Cittern, David. "Computational models of attachment and self-attachment." Thesis, Imperial College London, 2016. http://hdl.handle.net/10044/1/45314.
Full textAbstract:
We explore, using a variety of models grounded in computational neuroscience, the dynamics of attachment formation and change. In the first part of the thesis we consider the formation of the traditional organised forms of attachment (as defined by Mary Ainsworth) within the context of the free energy principle, showing how each type of attachment might arise in infant agents who minimise free energy over interoceptive states while interacting with caregivers with varying responsiveness. We show how exteroceptive cues (in the form of disrupted affective communication from the caregiver) can result in disorganised forms of attachment (as first uncovered by Mary Main) in infants of caregivers who consistently increase stress on approach, but can have an organising (towards ambivalence) effect in infants of inconsistent caregivers. The second part of the thesis concerns Self-Attachment: a new self-administrable attachment-based psychotherapy recently introduced by Abbas Edalat, which aims to induce neural plasticity in order to retrain an individual's suboptimal attachment schema. We begin with a model of the hypothesised neurobiological underpinnings of the Self-Attachment bonding protocols, which are concerned with the formation of an abstract, self-directed bond. Finally, using neuroscientific findings related to empathy and the self-other distinction within the context of pain, we propose a simple spiking neural model for how empathic states might serve to motivate application of the aforementioned bonding protocols.

Full textAbstract:
This paper seeks to explore the development of attachments in humans as seen through Bowlby's (1980) attachment theory. Components of the theory which focus on how attachments are formed and how they influence future behavior are explored. These are used to then examine how attachment theory applies to the attachment patterns seen in homosexual males.

In this study, results from Epstein's (1983) study were replicated and parental acceptance was found to be significantly correlated with measures of global self-esteem and lovability. This study extends his work to examine the unique effect of parental nonconcordance (i.e., one parent experienced as accepting and the other parent experienced as rejecting). Undergraduate students (N = 259) completed the Mother-Father-Peer Scale and the Multidimensional Self-Esteem Inventory. Results of the hierarchical multiple regression analysis supported the hypotheses that mother acceptance is a better predictor of global self-esteem and lovability than father acceptance in cases of parental nonconcordance. The results are discussed in lights of Bowlby's (1969/1982. 1973, & 1980) attachment theory, the construct of internal working models of attachment and the hierarchical nature of these models.Department of Counseling Psychology and Guidance Services

Bodinetz, M. "Using the child attachment interview to identify disorganised attachment." Thesis, University College London (University of London), 2008. http://discovery.ucl.ac.uk/1444111/.
Full textAbstract:
The question addressed in this review was whether or not the available empirical evidence suggested a significant association between childhood maltreatment and insecure attachment. In particular the focus was on the disorganised category of attachment insecurity as attachment theory considers this to be the most problematic attachment classification in terms of the links to later psychopathology (Carlson, 1998). The purpose of this paper was therefore to review the empirical evidence of an association between childhood maltreatment and attachment insecurity and, through a meta-analysis, calculate the odds ratios associated with a maltreated child being classified as having an insecure attachment style, in particular disorganised attachment. Following a literature search that yielded 84 citations, 12 studies were identified that met the inclusion criteria (see method section for details of the systematic search). The results of the meta-analysis showed that children who had been maltreated were at a significantly greater risk of having an insecure attachment pattern. In particular, the disorganised attachment classification showed a greater association than either the avoidant or preoccupied classifications. These findings support the theoretical link between childhood maltreatment and attachment insecurity and suggest that disorganisation of the attachment system is a possible mediator of the negative outcomes associated with childhood maltreatment. This would indicate the necessity for further examination of this association, with particular focus on the disorganised attachment category.

Full textAbstract:
This thesis, presented in partial fulfillment of the requirements for the degree of Master of Business Administration/Master of Fine Arts in Theatre Management, identifies the antecedents of emotional attachment to the theatre industry and specific organizations. The five identified antecedents of theatre emotional attachment are: social bonding, audience co-creation of value, escapism, cannon of work, and organizational culture. These emotional attachments can be leveraged through marketing efforts to increase the lifetime value of a patron and raise the overall profitability of the theatre organization.

Elliott, Amy Margaret. "Attachment and caregiving." Thesis, University of Birmingham, 2013. http://etheses.bham.ac.uk//id/eprint/3974/.
Full textAbstract:
This thesis is comprised of two volumes submitted to fulfil the academic requirements for the degree of Doctor of Clinical Psychology (Clin.Psy.D), School of Psychology, University of Birmingham. The first volume contains three papers which explore the broad theme of attachment and caregiving. The first paper, a literature review, examines the role of the caregiver in helping the infant to establish a secure attachment relationship. Specifically, it explores whether the caregiver’s ability to understand the world from the infant’s perspective is conducive to the development of attachment security. The second paper, reports an empirical study which considers caregiving in spouse partnerships where one person has dementia. The research explores caregivers’ perceptions of change within their relationship from an attachment perspective. It was hypothesised that attachment theory may potentially help to explain why some individuals experience continuity and others discontinuity. The third paper is a public domain briefing paper which comprises a summary of the literature review and empirical paper. This includes a case formulation (from two different psychological perspectives), a service evaluation, a single case experimental design and a case study. The last report is an abstract describing a case study clinical presentation.

McKay, J. M. "Attachment and psychotherapy." Thesis, City University London, 2010. http://openaccess.city.ac.uk/8727/.
Full textAbstract:
The aim of this study was to explore the relationship between therapy outcome, the therapeutic alliance and both patient and therapist attachment styles. 14 therapists and 27 patients participated. 78.57% (n = 11) therapists and 29.63% (n = 8) patients were classified as securely attached by self-report measures. It was predicted that more patients of secure therapists would show clinically significant improvement as determined by CORE-OM scores. However, 21.05% of patients with a secure attachment style therapist compared to 40% of patients with a dismissing attachment style therapist showed clinically significant improvement. Short-term therapies of once-weekly intensity enabled dismissing style patients to restore their defences, reduce distress and show clinically significant change in terms of reduction of symptomatology. There did not appear to be an association between attachment style of either therapist or patient and overall ratings of the alliance in this study. However, changes in both therapist and client ratings of the ARM subscales for Confidence and Openness between Time 1 and Time 2 suggested that therapist and client were beginning to perceive the alliance more similarly as therapy progressed. Mediation of the relationship between attachment style and therapeutic outcome by the therapeutic alliance was not found to be significant. A significant finding in this study was that patient participants were more likely to have only brothers and no sisters (51.9%, n = 14), X2 = 13.15, df = 3, p = 0.004.

Full textAbstract:
The purpose of this thesis was to examine the relationship between adult attachment style and health. Design Three questionnaire studies and one interview study were completed. Method . Questionnaires were administered to examine the relationship between attachment style and symptom reporting in healthy undergraduates (study 1) and cardiac patients (study 3). In Study 2 physiological response to stress was also measured. Study 4 used a semi structured interview approach to examine illness experience in cardiac patients. Results In study 1 insecurely attached students reported more somatic, anxious, social dysfunction and depressed symptoms than secure students. This relationship was mediated by anger and social support. In study 2 baseline differences in cardiac output and total peripheral differences were found, however, no differences were found in response to stress. Furthermore, insecurely attached students reported more depressed symptoms than those classed as secure. No mediators were identified. In study 3 the relationship between attachment styles on symptom reporting was . examined in chronic heart failure (CHF) and transplant populations. Insecure CHF patients reported a greater number of symptoms than secure patients. Anger and social support mediated this relationship. Only one difference was reported in the transplant group, with insecurely attached transplant patients reported more depressed symptoms than those classed as secure. Finally,interviews in study 4 identified four themes of control, normality, social support and emotional disclosure. Standardised symptom reporting tools may not capture these elements of the patient experience, and attachment style may offer one explanation for the variations reported by respondents. Conclusion In conclusion, the results of this thesis support attachment related differences in symptom reporting behaviour in clinical and non clinical populations, and that anger and social support mediated this relationship. The research suggests that attachment style may be a valuable tool to be utilised within the health services.

Full textAbstract:
Abstract : The diagnostic criteria for Reactive Attachment Disorder (RAD) have remained fairly constant over the last few decades. However, the most recent change in the fifth version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatry Association; APA, 2013) is fairly significant, as the inhibited and disinhibited types of RAD that were found in the previous versions of the manual have been removed. RAD has been replaced with a definition that resembles in some ways the previous inhibited type. Diagnosed in early childhood, this disorder interferes with the child’s ability to form secure relationships with their attachment figures and others. One of the criteria that remain constant is that deprivation in the quality of early care is a risk factor for developing RAD. Although physical abuse and extreme neglect may be easier to identify, emotional neglect is more challenging as a variable to understand. There has been less research on RAD regarding the subtle interactions between mother and child. The theory of mentalization explores some of the complications that arise in attachment and relationships to others that are aggravated by neglect, abuse, and trauma (Bateman & Fonagy 2004). The infant relies on the sensitive attunement and capacity to mentalize of the primary caregiver to help him understand what he is experiencing. The first article uses mentalization and object relations theory applied to children with RAD, in order to facilitate an understanding of these children psychologically as well as certain aspects of the relationship with their mothers. The second article presents two case studies of mother-child dyads of children who have been diagnosed with RAD. The mother and child were evaluated with instruments that provided information regarding the mother’s capacity to mentalize and the child’s attachment representations. The objective of the case studies were meant to reveal how these instruments could be utilized for the specific scores, but also to illustrate what is transpiring psychologically in the relationship between mother and child. The capacity to mentalize of the mothers was measured with the Addendum to Reflective Functioning Scoring Manual (Fonagy, Steele, Steele, & Target, 1998) applied to the Parent Development Interview-Revised (PDI-R; Slade, Aber, Berger, Bresgi, & Kaplan, 2005). The results of the mother’s scores for mentalization were in the low and questionable range. The attachment representations of the children were evaluated through the use of the Attachment Focused Coding System (AFCS; Reiner & Splaun, 2008) applied to the Attachment Story Completion Task (ASCT; Bretherton, Ridgeway, & Cassidy, 1990). The results of the instrument revealed that the two children with RAD (inhibited and disinhibited type) had lowered scores for Supportive Mother and a tendency for Avoidant Attachment Behaviour and Communication. The notions of mentalization and attachment representations were shown to provide a more profound understanding of the mother and child dyad. These evaluation methods support considering a larger study to explore the link between the mother’s capacity to mentalize and the child’s attachment representations in children diagnosed with RAD.Résumé : Les critères diagnostiques du trouble réactionnel de l'attachement (TRA) sont demeurés relativement stables au cours des dernières décennies. Toutefois, la cinquième version du Manuel diagnostique et statistique des troubles mentaux (DSM-5; American Psychiatric Association; APA, 2013) propose un seul type de TRA, qui correspond au type inhibé de la quatrième version révisée (DSM-IV-TR; APA, 2000), au lieu de distinguer entre deux types, soit inhibé et désinhibé. Diagnostiqué dans la petite enfance, le TRA interfère avec la capacité de l'enfant à former des relations sécurisantes avec ses principales figures d'attachement qui demeure un des critères diagnostiques et un facteur de risque pour le développement du TRA. Bien que l’abus physique et la négligence extrême soient plus faciles à identifier, la négligence au plan affectif est plus subtile et difficile à comprendre. Peu de recherches portent sur les interactions subtiles entre les mères et les enfants ayant reçu un diagnostic de TRA. La notion de mentalisation explore les complications qui peuvent survenir dans la relation aux principales figures d’attachement et dans les interactions sociales dans un contexte d’abus et de négligence (Bateman & Fonagy 2004). Pour être en mesure de comprendre ce qu’il vit, l'enfant nécessite des figures d’attachement sensibles et capables de mentaliser. Dans le premier article, les théories relatives aux notions de mentalisation et des relations d’objet sont utilisées pour comprendre le fonctionnement psychologique des enfants et la relation qu’ils entretiennent avec leurs mères chez des jeunes présentant un diagnostic de TRA. Dans le second article, deux études de cas de dyades mère-enfant ou l’enfant a reçu un diagnostique de RAD sont présentés. Les études de cas avaient pour objectif d’illustrer que les notions de mentalisation et de représentation d’attachement ainsi que les instruments permettant de les mesurer pourraient être utilisé pour approfondir ce qui passe entre la mère et l’enfant aux plans psychologique et relationnel. La capacité de mentalisation des mères participant à l’étude a été mesurée à l’aide de l'Échelle du fonctionnement réflexif (Addendum to Reflective Functioning Scoring Manual; Fonagy et al., 1998) appliquée à l’Entrevue sur le développement du parent (Parent Development Interview-Revised; PDI-R; Slade et al., 2005). Les résultats de la capacité de mentalisation des mères se situent dans les catégories faible ou questionnable. Les représentations d'attachement des enfants ont été évaluées en utilisant le Système de cotation centré sur l’attachement (Attachment Focused Coding System. (AFCS; Reiner & Splaun, 2008) appliqué aux Histoires d’attachement à compléter (Attachment Story Completion Task, ASCT; Bretherton, Ridgeway, & Cassidy, 1990). Les enfants participant à l’étude, ayant respectivement un TRA de type inhibé et désinhibé, ont obtenus des scores faibles dans les échelles Mère soutenante et Évitement des comportements et des communications relatifs à l’attachement. La théorie et la recherche concernant la notion de mentalisation permettent de mieux comprendre les difficultés rencontrées chez les dyades mère-enfant dont les jeunes présentent un diagnostic de TRA. Les notions de mentalisation et de représentations d’attachement ont permis d’approfondir la compréhension des dyades mère-enfant. Les méthodes d’évaluation utilisées dans la présente étude pourraient être utilisés pour explorer le lien entre la capacité de mentalisation de la mère et les représentations d'attachement de l'enfant au sein d’un échantillon plus large d’enfants présentant un diagnostic de TRA.

Full textAbstract:
This study attempted to investigate father attachment using the dual primary attachment figure model by examining caregiving and exploration behaviors of mothers and fathers as they relate to attachment security utilizing an archival data set of 177 young adult females. A subsequent factor analysis of the involvement scales revealed four distinct items creating the caregiving variables (one for mother and one for father) and six items creating the exploration variables. Results showed that mothers engaged in caregiving and exploration behaviors more than fathers, but their exploration predicted mother attachment more than caregiving. Fathers engaged in more caregiving than exploration, but it was their involvement in exploration that was more strongly related to father attachment. These findings, which provide partial support for the dual primary attachment figure model, suggest that father exploration is a cornerstone for the father-child attachment relationship, but also predictive of mother-child attachment. Future studies should include observational assessments of father attachment as well as exploration in current assessments of father attachment.

Full textAbstract:
The interaction of low energy electrons with stable and unstable molecules has been investigated with particular emphasis on negative ions formed in dissociative electron attachment. The experiment includes a trochoidal electron monochromator and a time-of-flight mass spectrometer. Measurements of dissociative electron attachment to HCCCN have been made inspired by the presence of this molecule in many extraterrestrial environments and by recent theoretical calculations of electron attachment to HCCCN. Two regions of electron attachment were observed with formation of CCCN- at 1.56 eV and CCCN-, CN-, HCC- and CC at - 5.30 eV where 2 II shape resonances were predicted to be located. Quantum chemical calculations performed in this work confirm these dissociation processes follow electron attachment into empty rr* orbitals. Negative ions were also observed at higher energies due to core excited resonances. Metastable dissociation of SF6-* has been observed in competition with autodetachment after attachment of close to 0 eV electrons to SF6. The lifetime of SF6-* has been estimated from the present measurements as a function of electron energy and hence, the internal energy of the anion. Metastable dissociation of a number of substituted benzene rings, such as dinitrobenzene, has also been investigated. This appears to be the first experimental study of the metastable decay of molecular anions with known internal energies. Measurements of dissociative electron attachment to the unstable CS and molecules have been performed to obtain total cross sections for dissociative electron attachment and characteristic negative ion mass spectra 'fingerprints'. CS forms S- at 5.43 eV, Cat - 6.40 eV and S- at - 6.70 eV. Dissociative electron attachment to CF2 was not observed, and an upper limit of the absolute cross section for the formation of F+CF has been deduced. A potential application of dissociative electron attachment measurements to plasma diagnostics is considered.

Full textAbstract:
Eye Movement Desensitisation and Reprocessing (EMDR) therapy is a recommended treatment for Post-Traumatic Stress Disorder (PTSD). Despite its rapidly growing evidence base, relatively little is known about its treatment effects beyond improving PTSD symptoms. This preliminary study aimed to explore the capacity for EMDR to facilitate a change in attachment security in a clinical sample of adults experiencing symptoms of PTSD and Complex PTSD (CPTSD). It also explored the role of the therapeutic alliance. A within-subject, repeated-measures design was used. Participants received 10 EMDR sessions on average, as part of their routine care. Self-report measures of attachment, PTSD, CPTSD, and the therapeutic alliance were administered during therapy. No significant changes in attachment were observed; however, there was a trend in the expected direction. A significant reduction in PTSD scores was found, in addition to some associations between change in attachment security and change in PTSD and CPTSD symptoms. No significant relationship between the strength of the therapeutic alliance and attachment change was found. This study contributes to the emerging literature on change in attachment; however, the findings should be interpreted with caution due to limitations including the small sample size. Clinical implications and recommendations for future research are discussed.

Full textAbstract:
This thesis explores the association between adult attachment and psychological therapy by examining attachment as an outcome variable of therapy, as well as a predictor of therapy outcome. The literature review systematically explores research that has examined changes in attachment representations during psychological therapy. The purpose of the review is to enhance understanding of change processes in adult attachment and to provide empirical support to the premises of attachment theory. In spite of inconsistencies with regards to measurement and conceptualisation of attachment, the evidence suggests that attachment security increases during therapy, whereas insecurity decreases.The aim of the empirical paper was to examine the association between global adult attachment representations, specific attachment to the therapist, working alliance and response to individual Cognitive-Behaviour Therapy (CBT). The study also investigated changes in global attachment representations and their relationship with outcome. The results indicated that clients with greater secure attachment to the therapist showed greater improvements in symptoms, whereas clients with higher avoidant-fearful attachment to the therapist demonstrated less improvement. Significant improvements in attachment avoidance and anxiety were also associated with improvements in psychological symptoms, as was working alliance. No associations between adult global attachment and outcome were found. In paper 3, the approaches used within the current thesis are evaluated in terms of their strengths and weaknesses. Clinical implications of the findings are discussed and ideas for future research are outlined.

This research conceptualises luxury brand attachment and develops a measurement scale for the construct. Underpinned with self-expansion and social identity theory, a research model is proposed with a set of hypotheses to investigate the inter-construct relationships. The self-congruity aspect within the luxury brand attachment construct is postulated to be moderated by the influence of consumers’ public self-consciousness and the product’s private/public status. The findings of this research will provide meaningful insights for academics and practitioners.

Full textAbstract:
Insecure attachment styles in infants are linked to mental health difficulties in later life (Fearon, Lapsley, Bakermans-Kranenburg, van Ijzendoom & Roisman, 2010), and are consequently important for identifying individuals at risk for psychopathology. The reliable and valid measurement of attachment security in infants is well documented (Ainsworth, 1979) as are measures for adults (George, Kaplan, & Main, 1985). However, reliable and valid measurement of attachment in middle childhood remains underdeveloped. The Child Attachment Questionnaire (CASQ) and Child Attachment Style Interview (CAS!) (Bifulco, Moran, Ball & Bernazzani, 2002a; Bifulco, Moran, Ball & Lillie, 2002b) were investigated for reliability and validity. Rates of attachment styles were expected to reflect those found in other studies of attachment in middle childhood. Insecure attachment identified with the CASQ was expected to correlate with higher clinical symptom scores on the Strengths and Difficulties Questionnaire (SDQ) and lower self-esteem scores on the Rosenberg self-esteem scale. 132 participants aged 9-11 years from a community sample completed the CASQ, SDQ and Rosenberg scale, of which 23 participants also completed the CASI. Rates of attachment security were similar to comparison studies in middle childhood. Children categorised with insecure attachments (both avoidant and anxious) were found to have significantly higher rates of clinical symptoms than securely categorised participants, and participants categorised as anxiously attached had significantly lower rates of self-esteem than securely categorised participants. The CASQ scales of attachment correlated significantly positively with the CASl scales of attachment. However, the overall categorisation of attachment style between the two measures was non-significant. The CASQ demonstrated significant test-retest reliability when read-ministered after five months. Evidence was found for validity and reliability of the CASQ, and validity of the CAST. High numbers were also identified in the "mixed" and "can't classify" groups. Developments of the measures and clinical implications were discussed.

Cohen, Diane L. "Exploring the role of secondary attachment relationships in the development of attachment security." Thesis, University of North Texas, 2005. https://digital.library.unt.edu/ark:/67531/metadc4891/.
Full textAbstract:
The process by which earned-secures achieve attachment security in adulthood, despite having insecure parent-child relationships in childhood, was the focus of the current study. As internal working models are thought to be formed within relationships, specifically primary attachment bonds (Bowlby, 1969), it was postulated that secondary attachment relationships, specifically those that were positive, had the capacity to revise insecure models of self and other. In the current study, the secondary attachment histories of undergraduates who were earned-secure and continuously-insecure, or insecurely attached since childhood, were compared. A new measure of secondary attachment quality was developed (Questionnaire About Secondary Attachment Figures (Q-SAF)), which was used to measure undergraduates' perceptions of their past and current secondary attachment figures. Findings indicated that in comparison to continuous-insecures, earned-secures perceived their negative secondary attachment figures in adolescence as less mean. Earned-secures also reported being less dependent upon these figures' approval of them for their self-worth and more secure within these relationships. In adulthood, earned-secures reported more trust and intimacy with their positive secondary attachment figures. Compared to continuous-insecures, earned-secures described their peers as being more empathic and altruistic during childhood and more warm during adolescence; earned-secures also reported less dependency and greater closeness with their peers throughout development. Grandparents were listed the most frequently by earned-secures as positive secondary attachment figures during childhood and this number was more than double that for continuous-insecures. Further, earned-secures described their grandparents in childhood as being more altruistic and they reported being less concerned with receiving their acceptance. Siblings from childhood were described by earned-secures as being more empathic than those of continuous-insecures, yet earned-secures also reported greater dismissing attachment to their siblings and cousins in childhood. Significant others from adolescence were rated by earned-secures as being less mean than those of continuous-insecures and earned-secures reported being more securely attached to these relationships in both adolescence and adulthood. Implications of the current study and directions for future research are presented.

Full textAbstract:
This study explored the relationship between attachment quality and school connectedness in a high school sample of adolescents. Although there is a literature related to adolescent attachment quality and its effects on adjustment and development, relatively little attention has been paid to the relationship between parent and peer attachment and school connectedness. Further, these attachments and connections have yet to be examined among general and special education populations. Attachment quality has been correlated with identity development, self-esteem, competence, and psychopathology and has been investigated as a mediator in the relation between risk and resilience. School connectedness centers around the theory that when adolescents perceive consistent personal power, attention, and praise, they develop a sense of attachment to their school environment. Further, school connectedness, attachment to family, and positive peer bonds, respectively, have been viewed as protective factors, i.e., preventing adolescents from engaging in health risk behaviors (i.e., violence, risky sexual behavior, drug use, and dropping out of school) (U.S. Department of Education, 2006). The present study included 157 students, aged 15 to 18 years who participated in a longitudinal study (The Longitudinal Study of Co-morbid Disorders in Children and Adolescence). Using quantitative methodologies, analyses examined the relationships among gender, ethnicity, risk status and parent attachment, peer attachment, and school connectedness. Measures included self-report questionnaires of attachment quality and school connectedness in adolescence. Several major findings from the present investigation include: (1) higher ratings of attachment to parents were associated with higher ratings of school connectedness; (2) higher ratings of attachment to peers were associated with higher ratings of school connectedness; (3) students at risk reported less school connectedness than not at risk students; and (4) the effects of peer attachment on school connectedness were moderated by risk group.

Full textAbstract:
The attachment system is activated when a threat is perceived in the environment. Attachment style differences moderate the levels of this activation. Whereas anxiously attached people are more hypervigilant to attachment-related stress, avoidant people have an ability to suppress their attachment related thoughts under stressful conditions. The aim of the present study was to investigate whether the subliminal presentation of threat and attachment figure primes interfere with the cognitive task performance of participants with different attachment styles. It was hypothesized that anxious participants would perform worse than secure and avoidant participants under both conditions of attachment-related threat and attachment figure primes. Avoidant participants were expected to perform poorly only when a threat prime is followed by an attachment figure prime. The securely attached participants were expected to perform better than the other attachment groups. University students (N = 225) filled out a questionnaire package including the measures of attachment figure names (WHOTO), attachment anxiety and avoidance (The Experiences in Close Relationships, ECR)and they were administered computerized Signal Detection and Stroop tasks representing cognitive attentional performance in the laboratory. The results showed that attachment avoidance was a significant predictor of decreased cognitive performance, and attachment anxiety makes people vulnerable to cognitive performance decline only under certain circumstances of attachment system activation. Attachment security was identified to make individuals immune to the effects of threat or attachment figure availability priming on cognitive performance. The findings were discussed considering previous work and implications for cultural differences.

Full textAbstract:
The Manchester Attachment Story Task (MCAST) is an instrument developed to assess preschool and school-aged children’s attachment representations. It has previously not been validated for children below 4.5 years. This study examined the discriminative validity of MCAST against a series of potential factors that may threaten the validity of the measured attachment in four-year-olds. Specifically variations in; children’s; (1) age and (2) cognitive/language ability, administrators (3) experience and (4) style, and coders (5) inter-rater reliability, and these factors in relation to MCAST attachment classifications, disorganization-scores and narrative coherence were investigated. A total of 872 children were assessed using MCAST as a measure of attachment. Peabody Vocabulary Test III-r (PPVT) was used to assess language/ cognitive competence, and Språ 4 to assess language competence. There were no age effects in attachment classifications for the whole interview or for some of the vignettes, in narrative coherence or disorganization scores. PPVT and Språ 4 showed a significant relationship to the variance in attachment categories. PPVT accounted for 2.3 % of the variance in d-scores and 1.3 % of the variance in coherence. It was found significant negative relationship in administrators experience and children’s scores on disorganization. Coder’s factor measured by inter-rater reliability was low. It is discussed whether the results from the study can be reliable considering low inter-rater-reliability. According to findings related to children and administrator factors, the results indicate that MCAST can be used in younger children than it is previously validated for. A more comprehensive validation study and some adjustments in the manual are recommended.

Full textAbstract:
Background & Introduction: Violence is a pervasive problem that is extremely costly to our society. Research in this area is therefore crucial in order that prevention strategies can be considered. Attachment theory provides a useful framework for understanding violence as it acknowledges the importance of both interpersonal and developmental factors. The theoretical literature suggests that attachment is associated with violence, but the evidence was equivocal as to whether insecure attachment was a risk factor for criminality, psychopathology more generally, or both. Consequently, a systematic review of the literature was conducted using meta-analytic methods. Results indicated that insecure attachment was strongly associated with all types of criminality (i.e. sexual offending, violent offending, non-violent offending, and domestic violence) even in the absence of psychopathology. Further sub-group analyses indicated differences in attachment patterns between sexual offenders and violent offenders, for example. The implications of the findings are discussed and suggestions for further research made. The present empirical study sought to address some of the questions raised by the meta-analysis, and to consider the influence of potential mediating variables, as insecure attachment is not sufficient to fully explain offending behaviour. Consequently, theory of mind (ToM) and emotional intelligence (EI), two variables proposed to mediate the relationship between insecure attachment and violence, were examined in a sample of violent offenders. It was hypothesised the majority of the sample would be insecurely attached, and that deficits in ToM and EI would increase as attachment security decreased. The possibility that attachment served not only as a general risk factor, but also as a victim specific one, was explored by examining whether attachment pattern was related to victim choice. Method: Assessments of adult attachment, ToM, and EI were administered to a group of 49 violent offenders both with and without mental disorder. File information pertaining to whether participants had ever been violent towards a significant other or not was also collected in order to categorise participants into groups of those who had a history of violence towards attachment figures, and those who did not. Data were analysed using f-tests and Pearson product moment correlations. Results & Discussion: Consistent with the findings of previous research, the majority of the sample was found to be insecurely attached. They were also significantly more anxious and avoidant in their attachments in comparison with normative data. No significant differences in attachment were observed between the mentally disordered offending group and the non-mentally disordered offending group. Rather, the levels of insecurity were similarly high across both groups, which would be consistent with the notion that insecure attachment is associated with criminality more generally as opposed to simply being a risk factor for mental disorder. The proposed association between attachment insecurity and poorer ToM abilities was not supported. The entire sample was found to be slightly below average with respect to EI, and the hypothesis that as attachment insecurity increased EI would decrease was statistically supported. No significant differences in attachment were observed when comparing those who had a history of violence towards attachment figures and those who did not. The clinical and theoretical implications of the findings are discussed, as well as the strengths and limitations of the study. A number of recommendations for future research are made.

Full textAbstract:
Understanding why some people are entrepreneurial and some are not, and why some societies are entrepreneurial and some are not, has been the focus of much attention in management studies, economics, sociology and psychology. A better understanding of what influences individual and societal entrepreneurship is important, if sustainable human progress is to be fostered through the encouragement of new business development. An important means of increasing knowledge of entrepreneurial behaviour is the development of a better understanding of the psychological factors involved in this form of human achievement. This research sheds light on one of the psychological antecedents of entrepreneurial behaviour by exploring the relationship between adult attachment style and entrepreneurship.
Attachment theory suggests that the relationship an infant and it's primary caregiver (usually the mother) develop during the first 18 months of infancy, has important lifelong repercussions. The result of this relationship-building process is either a secure or an anxious attachment pattern. This very first human relationship becomes the template used in the development of subsequent close relationships. Adult attachment styles echo attachment styles identified in infanthood. One influential view of adult attachment patterns is that they are based on an individual's working model of self and working model of other. The attachment styles based on the working model theory are secure, dismissing, preoccupied and fearful: The first two being positive model-of-self attachment styles, and the latter two, negative model-of-self attachment styles. Entrepreneurship is a continuum of behaviour that is related to, and similar to, creativity. Creative people, and entrepreneurial people, appear to have shared similar, anxiety inducing, experiences in early childhood, and have many similar psychological characteristics. Thus, attachment theory, with its overtones of anxiety, may be related to both creative achievement, and entrepreneurship. This study explores the posited relationship between entrepreneurship and adult attachment style. In order to do this, a quantitative research protocol was developed that included the evaluation and modification of existing research instruments designed to measure the constructs of interest. The research proceeded through three main phases; the development of a theoretical argument relating entrepreneurship with attachment theory, a preliminary study that confirmed that theoretical association, and a main survey of small business owners that further explored the relationship.
The findings of the research supported the claim that attachment style is related to entrepreneurship. The first important, but not surprising finding was that business ownership was associated with positive model-of-self attachment style, but not with negative model-of-self attachment styles. Entrepreneurial orientation was also associated with attachment style in that business owners scoring high on entrepreneurial orientation also scored high on either secure or dismissing attachment. Of particular interest here was the apparent gender effect. Male business owners with high entrepreneurial orientation tended towards a secure attachment style, whereas female business owners with high entrepreneurial orientation tended towards a dismissing attachment style. A gender effect was also evident in other aspects of business ownership such as founding status, growth aspirations and perceptions of performance satisfaction. The final finding was that the research supported the notion that entrepreneurship is, indeed, a characteristic that varies in intensity amongst individuals, and as such should be considered to be a trait-like characteristic. Findings relating to the relationship between gender, entrepreneurship and attachment style have important implications for several groups of stakeholders interested in entrepreneurship. Governments that attempt to foster entrepreneurial behaviour can benefit from a greater understanding of the varying support needs of individuals with different psychological dispositions. Business owners themselves will also benefit from an understanding of how their business practices and outcomes might be affected by attachment style. Business educators and entrepreneurship scholars now have a deeper understanding of the individual psychological dispositions that affect entrepreneurial behaviour. This research provides a new platform from which the entrepreneurial psychology can be explored.Thesis (PhD Doctorate)

Full textAbstract:
The main objective of this thesis was to identify facilitators of strong maternal affective attachment bonds to children. First, a systematized review of the literature was conducted to gather and synthesize all the research over the last 25 years that has identified correlates and predictors of maternal affective attachment. The review found 26 articles relevant to the research question, and main findings from the existing literature were summarized. The main study of the thesis was built upon the findings of the review using data collected through an online survey of Canadian mothers. First, a latent profile analysis (LPA) was used to cluster mothers into maternal profiles based on their patterns of responses to measures of previously identified correlates and predictors of the maternal affective attachment; symptom distress related to symptoms of depression and anxiety, the dimensions of avoidance and anxiety in mothers’ adult romantic attachment, and mothers’ sense of parental efficacy and satisfaction in the maternal role. Then, a MANOVA was conducted to determine whether profile membership would account for a significant portion of the variance in the maternal affective attachment bond to children. Results indicated that maternal profiles characterized by lower symptom distress, lower romantic attachment avoidance and anxiety, and higher efficacy and satisfaction in the parental role reported higher affective attachment, and perceived more closeness and less conflict in their relationships with their children. The results of this thesis help to inform the scholarship of motherhood by identifying salient maternal experiences associated with positive family outcomes.

Full textAbstract:
The PlaceInGIS project is a comprehensive examination of how places can be represented using modern Geographic Information System (GIS). After decades of research, geographers now understand that places are dynamic features, whose fuzzy boundaries change over time, subject to internal and external forces. The long-term goal of the PlaceInGIS project is to make people's understanding of place visible, comparable and amenable to analysis.
Place attachment is a theoretical construct that permits the quantification, visualization and analysis of the importance of place. The method described makes use of two significant sub-components of place attachment, place dependence and place identity, to create fuzzy surfaces in a GIS.
After conducting a detailed GPS mapping exercise of the Colliery Dam Park study area in Nanaimo, British Columbia, Canada, 302 study participants were presented with a survey questionnaire between 2011 and 2012. The place attachment and place dependence components for each feature described were used to create "feature surfaces." These were then combined using a Fuzzy OR operator to generate a single "place attachment surface" for each individual, which can be compared against each other or summed to show the overall opinions of groups.
In the short term, we are developing an application called the Place Analysis System (PAS), which enables places to be adequately represented. There are numerous applications for the PAS, as it creates a foundation for the comparative study of place. For the first time, it is possible to visualize, take measurements and analyze place attachment. What was once an ephemeral concept has been made concrete and amenable to study. The PAS can analyze fuzzy boundaries, or the fuzzy boundaries can be defuzzified to be more compatible with traditional representations of data in a GIS. We examine two applications of the PAS, one as a tool for site planning, and the other for the geographical analysis of core and periphery. These applications demonstrate the utility of the PAS, and we conclude by considering further applications and modifications to make the method easier to employ in future studies.Arts, Faculty of

Full textAbstract:
Whilst transient dissociative states are commonplace in the face of overwhelming traumatic events, long-standing dissociative phenomena are also frequently reported in adults who have childhood histories of severe sexual or physical abuse. Dissociation itself may take a number of forms, including isolation, adsorption, fragmentation and memory disturbance: the relative importance of environmental and personality variables in determining an individual's "style" of dissociation is unclear, although there is good evidence for a cumulative effect, such that dissociation in the face of trauma is most frequent in individuals who have also suffered childhood abuse. Bowlby's attachment theory may help to explain the relationship between social support, dissociative phenomena and traumatic events in childhood and adulthood. Attachment theory is a theory of affect regulation which proposes that individuals make use of social and cognitive strategies in their attempts to manage negative affect. These strategies are thought to be selected on the basis of an individual's childhood experiences with caregivers and are maintained through the operation of relatively stable "internal working models". Social support is widely cited as a protective factor mitigating against the development of psychopathology following exposure to trauma, but it is unclear whether social support directly protects against the effects of trauma, or whether both perceived social support and adaptation to trauma reflect underlying attachment patterns, as suggested by attachment theory. This thesis examines the relationship between attachment pattern and (i) tendency to experience particular dissociative states and (ii) use made of available social support. Two groups were recruited. These were (i) control subjects with no history of treatment for psychological problems, and (ii) out-patient psychology department attendees with a broad range of psychological problems. Measures of attachment, social support, dissociation, exposure to life events and mood were administered. The results are presented and discussed in light of current theories of attachment, social support and dissociation.

Full textAbstract:
This thesis work is based on the analysis of a fan blade attachment whereby a complete 3D model is presented by a partner company. The acceptability of a new design regarding the mechanical loads consisting of dividing the hub into two parts instead of using a solid hub is studied. From the model some critical parameters for the attachment of the blade with respect to the stresses are chosen such as the rotational speed, fillet size of the blade and the neck size of the blade. Parametric studies of these parameters are carried out in order to suggest the new design. Bearing in mind that a safety factor of 2 is the prerequisite, based on the analysis performed on ANSYS Workbench, it is suggested from the preliminary design that the axial fan can operate in two specific scenarios consisting of a rotational speed of 1771 rpm and a rotational speed of 1594 rpm. Using this set of parameters, a suggestion is drawn up on the blade fillet which will give lower stress. Blade fillet size of 30 to 35mm is recommended while a size of 45mm is recommended on the neck of the blade. A modal analysis is performed in order to find at what frequency will the model be vibrating and a lowest and critical frequency of 16.8 Hz is obtained. Finally, a fatigue analysis of some interesting areas is performed in order to determine the numbers of cycles before fatigue failure occur. It is recommended to use the rotational speed since these speeds have offered a High Cycle Fatigue results.

Full textAbstract:
Preferential attachment networks with power law degree sequence undergo a phase transition when the power law exponent τ changes. For τ > 3 typical distances in the network are logarithmic in the size of the network and for 2 < τ < 3 they are doubly logarithmic. In this thesis, we identify the correct scaling constant for τ ∈ (2, 3) and discover a surprising dichotomy between preferential attachment networks and networks without preferential attachment. This contradicts previous conjectures of universality. Moreover, using a model recently introduced by Dereich and Mörters, we study the critical behaviour at τ = 3, and establish novel results for the scale of the typical distances under lower order perturbations of the attachment function.
