Full textThe unresolved question of whether Fear of Success is a motive or a measure of gender-role stereotypes is at the centre of the confusion about this construct. The purpose of the present study was to re-explore the nature of Fear of Success through the relationship of this construct to other theoretically related variables. The list of variables included Self-Efficacy, Autonomous and Social Achievement Values, Attitudes Towards Women, Positive and Negative Affect and Age. Cronbach and Meehl's (citedin Tresemer, 1976a) statement that the nomological net of propositions in which a construct is embedded must show predicted relationships with that construct, fostered the expectation that at least some of these variables would predict Fear of Success. It was anticipated that establishing a relationship with either the sociological or the personality constructs would clarify the nature of Fear of Success. The sample consisted of 240 white, English-speaking Capetonian women. The sample was restricted to women from the same cultural group so as to avoid the introduction of confounding variables, and to facilitate comparison of the results with the bulk of the research, most of which has been conducted in America. Furthermore, subjects were drawn from the working population· rather than students, as many researchers in this field have done, so that results would be generalizable to the workplace. Each subject was administered a questionnaire containing the following scales: Good and Good's(1973) Fear of Success Scale, The Positive and Negative Affect Schedule which was developed by Watson, Clark and Tellegen (1988), Tipton, Everett and Worthington's(1984) Generalized Self-Efficacy Scale, Spence and Helmreich's (1972) Attitudes Towards Women Scale and the Autonomous and Social Achievement Values Scale which was compiled by Strümpfer (1975).

Full textContextual fear conditioning involves pairing a novel context (conditioned stimulus) with several footshocks (unconditioned stimulus) that serve to condition fear to that context. As the retention interval between training and testing increases context specificity is lost. In other words, the fear memory is no longer precise or context-specific, but has generalized to novel contexts at remote time points. In an attempt to investigate the neural pattern of an imprecise contextual memory trace as a function of time, we used fluorescent in situ hybridization to for Arc mRNA as a measure of neuronal activation following expression of a precise vs. imprecise context fear memory. Expression of a contextually precise memory involved increased Arc mRNA expression in both the dorsal and ventral CA1 regions of the hippocampus as well as the ACC and IL. Expression of a contextually imprecise fear memory involved Arc mRNA expression in the ventral CA1, ACC, IL, and the PL suggesting that both the hippocampus and prefrontal cortex are involved in the expression of a remote contextually imprecise memory. Further, inactivation of the ACC at remote time points returned the context memory to a precise state, but had no effect on memory for the training context. Taken together, these data suggest that as a context fear memory ages, both the hippocampus and prefrontal cortex interact in the expression of the memory trace resulting in the loss of precision. Preventing this interaction through inactivation of the ACC allows the hippocampus to express the contextually precise memory. In addition to the systems investigation of fear generalization, we also investigated a potential synaptic mechanism of the phenomenon. Specifically, we discovered that mice lacking a GABAB1 receptor subtype, GABAB1a, exhibit a loss of context discrimination compared to wild-type animals. Animals lacking GABAB1a receptors showed a significant, but not complete loss of context specificity 24 hours post-training. GABAB1a knock out mice exhibited a complete loss of context discrimination by 5 days post-training. However, knock out mice exhibited normal context discrimination immediately following training, suggesting that GABAB1A receptors are necessary for the retention, but not acquisition, of context discrimination. Our results indicate that presynaptic inhibition is required for the maintenance of context.

Full textThe present thesis explored the neurobiological basis of three aspects of defense behaviors in humans. Positron emission tomography methodology was used, and changes in regional cerebral blood flow (rCBF) were measured as an index of neural activity. Firstly, brain function was studied in a group of patients suffering from combat-related posttraumatic stress disorder, using a symptom provocation paradigm with combat sounds in order to elicit fear. Exposure to auditory trauma reminders relative to neutral sounds was associated with increased rCBF in sensorimotor areas, the cerebellar vermis, the periaqueductal gray matter, and the right amygdala, whereas decreased activity was observed in the retrosplenial area of the posterior cingulate cortex. Secondly, the neural circuitry mediating the acoustic startle response and its habituation was studied in a group of healthy subjects. During acoustic startle stimulation as compared to a resting condition, increased rCBF was found in a medial posterior area of the pons corresponding to the nucleus reticularis pontis caudalis. As a result of startle repetition, altered activity was found in the cerebellum, pointing to its involvement in startle habituation. Thirdly, neural activity associated with startle modulation by phobic fear was studied in a group of subjects with specific animal phobias during exposure to pictures of their feared and non-feared objects, paired and unpaired with acoustic startle stimuli. As a result of startle potentiation, increased rCBF was found in the left amygdaloid-hippocampal region, and medially in the affective division of the anterior cingulate cortex. In conclusion, these results provide evidence for the involvement of limbic and paralimbic brain areas during fear provocation and fear-potentiated startle and for a similar neurocircuitry underlying startle in humans and animals.

Full textThis thesis explores different ways the media influences the psyche and society. Although research has found some positive effects, it points to primarily negative impacts, including manipulating emotions, instilling fear, promoting racism, influencing social control, and ultimately impacting peoples’ perceptions of reality and the world, which can extend into problematic effects on the electoral process and the shaping of popular culture. North Americans can be adversely impacted by media images and content to which they are exposed daily. Negative and fear-producing content can contribute to mental illness as well as societal degeneration. This thesis uses a hermeneutic methodology to identify ways in which the media may be negatively impacting the psyche. The research suggests connections between media and the contents of the cultural unconscious related to the American dream, female objectification, and fear of the other. It posits that fear-producing media can be seen as a form of psychological abuse.

Full textAnxiety disorders are the most prominent mental disorder in the United States, and women are 60% more likely than men to have an anxiety disorder. One hypothesis for this sex difference is faster fear generalization rates in females. In previous studies using male subjects, context change disrupted a fear response at a short, but not long retention interval. An incidental observation suggested that females would show a different temporal pattern of fear generalization. In Experiment 1, male and intact female rats displayed disrupted fear responses in a novel context at 1 day. Males displayed context discrimination at all intervals, whereas females exhibited generalization by 5 days. In Experiment 2, ovariectomized females were given an empty capsule or a capsule containing 17β-estradiol to determine the role of estrogens in fear generalization. Female rats with no hormone replacement displayed context discrimination at 5 days, whereas those receiving estradiol generalized their fear response to a novel context. These results demonstrate that fear generalization for contextual cues occurs faster in female rats and that this effect is mediated, in part, by estrogens. Understanding the sex differences in fear generalization is likely to be critical to developing effective treatments for anxiety disorders.

Full textLimited research has attempted to quantify Fear of Missing Out. Only one prior study has examined adolescents’ experience of Fear of Missing Out and did so with a small, homogenous Belgian sample. In order to expand upon this limited research base, the present study sought to examine Fear of Missing Out with an American adolescent sample. Specifically, the purpose of the present study was to analyze the reliability and validity of the Fear of Missing Out Scale (Przybylski, Murayama, DeHaan & Gladwell, 2013) that was originally developed with an adult population, as well as strengthen understanding of Fear of Missing Out as it pertained to specific demographics. Students (grades 5–12) participating in a large, urban school district after school program in North Texas were surveyed on their experience with Fear of Missing Out and frequency of social media engagement (n = 961; 55% male). Results of a principal components analysis confirmed the presence of a 1-factor model, maintaining all 10 original scale items with strong internal consistency (α = 0.93). Regression analysis suggested Fear of Missing Out was predictive of increased social media engagement ( p = .003). Gender and ethnicity were not related to Fear of Missing Out; grade level and Fear of Missing Out were inversely related, such that the older a student was, the less Fear of Missing Out was reported. Future researchers should utilize intentional and purposeful methodology for measuring social media engagement and focus on strengthening the validity and reliability of Fear of Missing Out as a unique construct. Further, theorists should consider updating their developmental perspectives related to adolescence based on advances in technology, media consumption, and interpersonal communication, particularly via social media. Practitioners are encouraged to understand and disseminate this information as it pertains to educating adolescents and their families about the benefits and costs of mobile technology and social media engagement.

Full textLa douleur et l'invalidité persistante sont souvent associées avec des blessures musculo-squelettiques et peuvent entrainer une souffrance personnelle majeure ainsi qu'un fardeau social considérable. Le Modèle Cognitivo-Comportemental de la Peur liée à la douleur (MCCP) donne un compte rendu théorique de la manière dont l'invalidité associée à la douleur se développe et a inspiré une grande partie de la recherche qui vise à atténuer les conséquences de blessures musculo-squelettiques. Tandis que le MCCP est la théorie de premier ordre sur l'invalidité associée à la douleur, plusieurs aspects théoriques et empiriques du modèle n'ont pas encore été pleinement adressés. Cette thèse vise à examiner ces aspects. Cette thèse consiste en cinq chapitres : une introduction générale, trois études empiriques et une conclusion générale. L'introduction présente le cadre théorique pour les trois études empiriques. Les études incluses dans cette thèse visent à combler deux lacunes empiriques ; les études évaluent des relations prospectives spécifiques proposées par le MCCP, et examinent les relations alternatives entre les variables pertinents au modèle. La discussion générale fournit une exploration détaillée de diverses hypothèses théoriques développées dans le MCCP qui peuvent aider à expliquer les résultats des trois études.

Full textLa peur et le stress sont deux concepts psychologiques intimement reliés. Au niveau biologique, l'activité du système nerveux sympathique (SNS), mesuré par la réponse électrodermale (RÉD), est considéré comme un marqueur de la peur chez l'être humain. Parallèlement, la sécrétion de cortisol suite à l'activation de l'axe hypothalamo-hypophyso-adrénergique (HHA) est le marqueur le plus commun du stress. Cependant, peu d'études se sont penchées sur l'interaction entre le cortisol et la RÉD lors d'un conditionnement de peur pavlovien chez l'être humain. De plus, le conditionnement de peur est utilisé comme modèle pour étudier le Trouble de Stress Post-Traumatique (TSPT). Ce trouble est considéré comme un échec de supprimer une réaction de peur exagérée acquise lors du traumatisme. Le cortisol, en tant qu'hormone de stress principale, est considéré comme un agent qui influencerait la force des réactions de peur dans le TSPT. Cependant, il demeure incertain si le TSPT est principalement un trouble relié à la peur ou si sa symptomatologie est relié à d'autres facteurs, tels le cortisol ou des structures neurologiques qui ne sont pas associées au système de la peur.Les travaux de cette thèse suivent deux lignes parallèles. Les deux premiers chapitres présentent les résultats de l'étude de l'interaction entre la peur et le stress chez des participants en santé. Nous illustrons que l'exposition à un conditionnement de peur n'est pas suffisant pour provoquer une réponse de cortisol. De plus, nous avons observé une plus forte réactivité au conditionnement chez les femmes. Les résultats de notre deuxième étude indiquent qu'une augmentation de cortisol endogène est associé à un déclin plus rapide de la réponse au stimulus conditionné lors de l'extinction. Cette étude confirme aussi une plus forte réactivité chez les femmes. Enfin, alors que la sécrétion de cortisol est associée à l'adversité durant l'enfance et l'anxiété, la RÉD n'était pas associée aux traits de personnalité.Parallèlement à ces études, nous avons étudiés des civils exposés à un événement traumatique. Notre troisième étude montre qu'une réponse accrue de cortisol en réaction au réveil est associée à la résilience face à un événement traumatique. De plus, notre étude de l'épaisseur corticale a confirmé que, chez des individus récemment exposés à un événement traumatique, le cortex cingulaire antérieur est correlé négativement à la sévérité des symptômes. Cette étude a aussi mis en lumière deux nouvelles structures, le cortex ventro-temporal et le pôle frontal, qui sont associées à la sévérité des symptômes. Ces deux structures ajoutent une dimension cognitive et sociale à la sévérité du TSPT et sont associés plus fortement au stress qu'à la peur en soi. Elles suggèrent donc un modèle d'étude qui va au-delà du conditionnement de peur et qui intègre l'importance du stress pour mieux décrire la symptômatologie.Je conclue cette thèse en réexaminant le modèle d'interaction entre le stress et les mesures périphériques de la peur. Suivant cela, j'examine le sexe comme médiateur possible dans l'apprentissage de peur, la réactivité au stress et l'extinction de la peur. Enfin, je fais le pont entre les premières études et celles sur le TSPT pour évaluer l'usage du pur conditionnement de peur comme modèle pour décrire l'émergence et le maintient des symptômes.
