Full textAbstract:
Perceptual biases can be interpreted as adverse consequences of optimal processes which otherwise improve system performance. The review presented here focuses on the investigation of inaccuracies in multisensory perception by focusing on the perception of verticality and self-motion, where the vestibular sensory modality has a prominent role. Perception of verticality indicates how the system processes gravity. Thus, it represents an indirect measurement of vestibular perception. Head tilts can lead to biases in perceived verticality, interpreted as the influence of a vestibular prior set at the most common orientation relative to gravity (i.e., upright), useful for improving precision when upright (e.g., fall avoidance). Studies on the perception of verticality across development and in the presence of blindness show that prior acquisition is mediated by visual experience, thus unveiling the fundamental role of visuo-vestibular interconnections across development. Such multisensory interactions can be behaviorally tested with cross-modal aftereffect paradigms which test whether adaptation in one sensory modality induces biases in another, eventually revealing an interconnection between the tested sensory modalities. Such phenomena indicate the presence of multisensory neural mechanisms that constantly function to calibrate self-motion dedicated sensory modalities with each other as well as with the environment. Thus, biases in vestibular perception reveal how the brain optimally adapts to environmental requests, such as spatial navigation and steady changes in the surroundings.

The ongoing state of the brain radically affects how it processes sensory information. How does this ongoing brain activity interact with the processing of external stimuli? Spontaneous oscillations in the alpha range are thought to inhibit sensory processing, but little is known about the psychophysical mechanisms of this inhibition. We recorded ongoing brain activity with EEG while human observers performed a visual detection task with stimuli of different contrast intensities. To move beyond qualitative description, we formally compared psychometric functions obtained under different levels of ongoing alpha power and evaluated the inhibitory effect of ongoing alpha oscillations in terms of contrast or response gain models. This procedure opens the way to understanding the actual functional mechanisms by which ongoing brain activity affects visual performance. We found that strong prestimulus occipital alpha oscillations—but not more anterior mu oscillations—reduce performance most strongly for stimuli of the highest intensities tested. This inhibitory effect is best explained by a divisive reduction of response gain. Ongoing occipital alpha oscillations thus reflect changes in the visual system's input/output transformation that are independent of the sensory input to the system. They selectively scale the system's response, rather than change its sensitivity to sensory information.

Many concepts of the human personality are based on assumptions about underlying physiological processes. The most prominent example is probably the concept of extraversion introduced by H.J. Eysenck decades ago. However, more recent approaches also propose that personality traits may be reflected by physiological processes. For example, empathic personality dimensions have been linked to tactile perception, suggesting that individuals with higher tactile sensitivity are also more empathetic to the sensations of others. Another recent example is the concept of sensory processing sensitivity, which has been linked to enhanced primary sensory processing. However, the exact relationship between tactile abilities and personality is still unclear, thus the current study aims to test whether different personality dimensions affect the performance in a tactile acuity task. Tactile abilities of healthy participants were tested with tactile 2-point-thresholds on the hands. Personality dimensions were examined with respect to empathy, sensory processing sensitivity, and the Big Five. Results revealed that empathy, but not sensory processing sensitivity, was associated with tactile performance. We conclude that the ability to feel with someone else seems to be linked to the perception of our own body. Thus, the sense of touch may play an important role for empathy. We discuss explanations of these results and highlight possible implications of our findings.

Two experiments are described. In Exp. 1, subjects compared the apparent numerosity of two kinds of dot patterns, regular vs irregular, with two different exposures (160 vs 2000 msec). In Exp. 2, the subjects had to estimate the numerosity of the same patterns, presented one at a time. Analysis showed a relative overestimation of the regular patterns in Exp. 1 but not in Exp. 2. In general an overestimation occurred with an increase in exposure. Such results support our hypothesis of two separate processes as the basis of the two kinds of performance (estimating vs comparison).

Full textAbstract:
Abstract Illusory contours (ICs) are borders that are perceived in the absence of contrast gradients. Until recently, IC processes were considered exclusively visual in nature and presumed to be unaffected by information from other senses. Electrophysiological data in humans indicates that sounds can enhance IC processes. Despite cross-modal enhancement being observed at the neurophysiological level, to date there is no evidence of direct amplification of behavioural performance in IC processing by sounds. We addressed this knowledge gap. Healthy adults () discriminated instances when inducers were arranged to form an IC from instances when no IC was formed (NC). Inducers were low-constrast and masked, and there was continuous background acoustic noise throughout a block of trials. On half of the trials, i.e., independently of IC vs NC, a 1000-Hz tone was presented synchronously with the inducer stimuli. Sound presence improved the accuracy of indicating when an IC was presented, but had no impact on performance with NC stimuli (significant IC presence/absence × Sound presence/absence interaction). There was no evidence that this was due to general alerting or to a speed–accuracy trade-off (no main effect of sound presence on accuracy rates and no comparable significant interaction on reaction times). Moreover, sound presence increased sensitivity and reduced bias on the IC vs NC discrimination task. These results demonstrate that multisensory processes augment mid-level visual functions, exemplified by IC processes. Aside from the impact on neurobiological and computational models of vision, our findings may prove clinically beneficial for low-vision or sight-restored patients.

Full textAbstract:
It has been proposed that temporal perception and performance depend on a biological source of temporal information. A model for a temporal oscillator put forward by Treisman, Faulkner, Naish, and Brogan (1990) predicted that if intense sensory pulses (such as auditory clicks) were presented to subjects at suitable rates they would perturb the frequency at which the temporal oscillator runs and so cause over- or underestimation of time. The resulting pattern of interference between sensory pulse rates and time judgments would depend on the frequency of the temporal oscillator and so might allow that frequency to be estimated. Such interference patterns were found using auditory clicks and visual flicker (Treisman & Brogan, 1992; Treisman et al., 1990). The present study examines time estimation together with the simultaneously recorded electroencephalogram to examine whether evidence of such an interference pattern can be found in the EEG. Alternative models for the organization of a temporal system consisting of an oscillator or multiple oscillators are considered and predictions derived from them relating to the EEG. An experiment was run in which time intervals were presented for estimation, auditory clicks being given during those intervals, and the EEG was recorded concurrently. Analyses of the EEG revealed interactions between auditory click rates and certain EEG components which parallel the interference patterns previously found. The overall pattern of EEG results is interpreted as favouring a model for the organization of the temporal system in which sets of click-sensitive oscillators spaced at intervals of about 12.8 Hz contribute to the EEG spectrum. These are taken to represent a series of harmonically spaced distributions of oscillators involved in time-keeping.

Full textAbstract:
Abstract Gilles de la Tourette syndrome is a multifaceted neurodevelopmental disorder characterized by multiple motor and vocal tics. Research in Tourette syndrome has traditionally focused on the motor system. However, there is increasing evidence that perceptual and cognitive processes play a crucial role as well. Against this background it has been reasoned that processes linking perception and action might be particularly affected in these patients with the strength of perception-action binding being increased. However, this has not yet been studied experimentally. Here, we investigated adult Tourette patients within the framework of the ‘Theory of Event Coding’ using an experimental approach allowing us to directly test the strength of perception-action binding. We included 24 adult patients with Tourette syndrome and n = 24 healthy control subjects using a previously established visual-motor event file task with four levels of feature overlap requiring repeating or alternating responses. Concomitant to behavioural testing, EEG was recorded and analysed using temporal signal decomposition and source localization methods. On a behavioural level, perception-action binding was increased in Tourette patients. Tic frequency correlated with performance in conditions where unbinding processes of previously established perception-action bindings were required with higher tic frequency being associated with stronger perception-action binding. This suggests that perception-action binding is intimately related to the occurrence of tics. Analysis of EEG data showed that behavioural changes cannot be explained based on simple perceptual or motor processes. Instead, cognitive processes linking perception to action in inferior parietal cortices are crucial. Our findings suggest that motor or sensory processes alone are less relevant for the understanding of Tourette syndrome than cognitive processes engaged in linking and restructuring of perception-action association. A broader cognitive framework encompassing perception and action appears well suited to opening new routes for the understanding of Tourette syndrome.

Full textAbstract:
The importance of forming primary school children’s musical perception is justified by the introduction of the new version of the educational standard and educational programs as well as by teaching Arts on the basis of an integrative methodological approach. The purpose of the article is to scientifically ground the system of didactic influences on musical perceptual processes of younger school children focusing on the following research tasks: a) to define sensory ability as a unit of functioning of musical perception; b) to characterize the levels of pupils’ musical sensory skills formed in the mass experience of primary education; c) to disclose the specifics of variable experimental effects which differ in the degree of intensity of intermodal connections of sensory channels; d) to compare the quality dynamics of musical sensory skills formation in different versions of the pedagogical experiment. Musical sensory ability is defined as the performance of a system of auditory interiorized perceptual familiarizing and cognitive actions based on the mastered standards of music sounds and skills of applying these standards in the examination of musical phenomena. It has been found that in the mass experience of primary education pupils master musical sensory skills at elementary, intermediate and sufficient quality levels where the intermediate one prevails. The system of exercises and game tasks has been developed on the basis of intermodality with coordination of musical and phonemic auditory, musical auditory and color visual, musical auditory and spatial visual sensory processes. The system is aimed at expanding and systematizing pupils' reference ideas about music sounds as well as forming rational ways of their examining musical phenomena. The effectiveness of the introduced didactic influences has been proved: in comparison with the control group the participants of experimental groups, especially the first one, have demonstrated both the highest efficiency of distinguishing and systematizing music sounds and a variety of skills to reproduce them in singing, spatial modelling and instrumental game. The following changes have taken place in the structure of experimental groups: the respondents with an elementary level of musical perception development have not been identified, but a level gradation with intermediate, sufficient, high and consistently high levels of mastery of musical sensory processes. Key words: musical sensory ability, standards of musical sounds, methods of examination of musical sounds, game tasks, exercises, younger students.

Full textAbstract:
In the context of fair trade and protection of consumer rights, the aim of this study was to combat adulteration, counterfeiting, and fraud in the tea market, and rebuild the image of high-quality Taiwan teas. Experts at the Tea Research and Extension Station, Taiwan (TRES), are engaged in promotion of the systems of origin identification (AOC) and grading for authentication of Taiwan’s premium teas. From tea evaluation competitions (bottom-up quality campaign), the flavor descriptions and consumers’ perceptions were deconvoluted and characterized for the eight Taiwan specialty teas, namely, Bi-Luo-Chun, Wenshan Paochong, High-Mountain Oolong, Dongding Oolong, Tieh-Kuan-Yin, Red Oolong, Oriental Beauty, and Taiwan black tea. Then, according to the manufacturing processes, producing estates and flavor characters, the specialty teas were categorized into six sensory wheels. The flavor descriptors of the sensory wheels were also recognized in consumers’ feedback. In recent years, the performance of international trade in tea also demonstrates that the policy guidelines for authentication of specialty teas are helpful to the production and marketing. Furthermore, the development of sensory wheels of Taiwan’s specialty teas is the cornerstone to the establishment of the Taiwan-tea assortment and grading system (TAGs) for communication with the new generation consumers, enthusiasts, sellers, and producers.

Find full textAbstract:
This thesis is concerned with creating and evaluating interactive art systems that facilitate emergent participant experiences. For the purposes of this research, interactive art is the computer based arts involving physical participation from the audience, while emergence is when a new form or concept appears that was not directly implied by the context from which it arose. This emergent ‘whole’ is more than a simple sum of its parts. The research aims to develop understanding of the nature of emergent experiences that might arise during participant interaction with interactive art systems. It also aims to understand the design issues surrounding the creation of these systems.
The approach used is Practice-based, integrating practice, evaluation and theoretical research.
Practice used methods from Reflection-in-action and Iterative design to create two interactive art systems: Glass Pond and +-now. Creation of +-now resulted in a novel method for instantiating emergent shapes. Both art works were also evaluated in exploratory studies. In addition, a main study with 30 participants was conducted on participant interaction with +-now. These sessions were video recorded and participants were interviewed about their experience. Recordings were transcribed and analysed using Grounded theory methods. Emergent participant experiences were identified and classified using a taxonomy of emergence in interactive art. This taxonomy draws on theoretical research.
The outcomes of this Practice-based research are summarised as follows. Two interactive art systems, where the second work clearly facilitates emergent interaction, were created. Their creation involved the development of a novel method for instantiating emergent shapes and it informed aesthetic and design issues surrounding interactive art systems for emergence. A taxonomy of emergence in interactive art was also created. Other outcomes are the evaluation findings about participant experiences, including different types of emergence experienced and the coding schemes produced during data analysis.

Tese de doutoramento em Ciências do Desporto e Educação Física (Ciências do Desporto) apresentada à Fac. de Ciências do Desporto e Educação Física de CoimbraApesar da influência que os comportamentos de liderança e de coesão de grupo parecem ter no rendimento desportivo, poucos são os estudos (Westre e Weiss, 1991 ; Antunes e Cruz, 1997 ; Leitão, 1997) que procuraram avaliar de uma forma processual e concorrente os construtos de liderança e de coesão. Assim, este estudo teve como objectivo geral analisar as relações entre o treinador e o atleta e em particular, observar a influência da percepção dos comportamentos de liderança e de coesão no rendimento desportivo. Os atletas (N=316, M=23.2 anos, DP=4.33) provenientes de 23 equipas de futebol participantes em campeonatos nacionais (2ª e 3ª divisão nacional) e distritais (1ª divisão distrital) foram avaliados em três momentos ao longo de uma época desportiva, através das escalas resultantes do Modelo Multidimensional de Liderança (Chelladurai, 1978, 1991) e do Modelo Conceptual de Coesão (Carron et al., 1985). Como medidas adicionais foram também utilizadas medidas de rendimento individual e de equipa. Desta forma, tendo em vista a análise psicométrica dos instrumentos teóricos de avaliação, foi efectuado um estudo factorial exploratório e confirmatório às escalas - Leadership Scale for Sports (LSS - Chelladurai e Saleh, 1978), Group Environment Questionnaire (GEQ - Carron et al., 1985) e à Satisfaction Scale for Athletes (Chelladurai et al., 1988). Através da análise multigrupos, foi igualmente testada a invariância dos parâmetros estruturais dos modelos de liderança, coesão e satisfação. Por sua vez, tendo em atenção os objectivos e hipóteses que orientaram este estudo, as técnicas estatísticas utilizadas - path-analysis, análise discriminante, análise multigrupos e meta-análise - permitiram verificar : i) a existência de diferenças significativas na percepção dos comportamentos de liderança, coesão e de satisfação em função da responsabilidade contratual dos atletas (profissionais e não profissionais) e do estatuto dos atletas (efectivo e não efectivo) ; ii) a instabilidade e mudança permanente dos processos de grupo ; iii) a existência de potenciais variáveis moderadoras (v.g., estatuto dos atletas, obrigação contratual, percepção do rendimento individual e colectivo) da percepção dos comportamentos de liderança, coesão e satisfação e iv) um efeito mais elevado entre o rendimento e coesão do que o observado entre este construto e o rendimento (posterior).

Full textAbstract:
This study presents an analysis of human encounter with place. It examines the personal and cultural importance of an attachment to place, focusing on the reciprocal relationship between cultural heritage and a sense of place. Place is constructed out of mutual meanings between people and their environment. The study begins with an indepth look at the theory of place. In a series of heritage management case studies, the theory is applied in order to illustrate how meanings of place may be expressed. Place as a normative concept provides a role for resource managers in finding the meanings people associate with places, and in nurturing and enhancing these meanings. This involves the recognition of different values and 'stories' that are associated with place. Recognising these differences helps shift resource management away from the simplicity of grand narratives and totalizing discourses, towards a respect for intangible and multiple meanings in place. To a certain extent an understanding of place is already informing both natural and cultural management decisions in New Zealand, although this may not be explicitly recognised. To approach cultural heritage management from the perspective of place, however, challenges the current directions that heritage management is taking in this country. The study proposes a way of taking up that challenge, and concludes that the importance of place should not be overlooked.

The technology availability and hype of virtual reality has intersected as of 2016, bringing a lot of attention to virtual reality (VR) games. The research into this technology has been ongoing since its early exploration in the 1970’s. Methods have been created to try to understand and predict what causes phenomena such as motion and simulator sickness in the human computer interaction devices. Heuristics have been developed to aid the design these applications and to avoid such discomforting circumstances. Concepts and their continued exploration have been growing to improve the experience of virtual reality technology and continue the expanding imagination of what is capable with this technology. All the tools are available to create highly immersive virtual experiences, but it is up to the interpretant, the user to decide how believable, immersive and enjoyable these experiences are. By conducting an interview study on a part of the VR gaming community, more can be understood about the success and failure of immersive design by exploring the experiences of certain highly immersive games. This study takes the opportunity to listen to gamers as a means of highlighting significant key challenges and characteristics creating immersive VR games. By evaluating transcripts via thematic analysis, themes were created to understand and categorize the various aspects that are most important to the immersion and embodiment in VR games. This study and themes drawn from it reflect on the experiences and feelings of experienced VR gamers in the context of role-playing games.

The purpose of this research was to investigate how work orientation (job, career, and calling) affects the professional life of leaders; and how leaders perceive their work regarding these three dimensions. In addition, this study aimed to relate work orientation to performance. Also, phenomenology approach allowed a deep investigation of the experience of leaders with regard to their work.
For this purpose, two surveys were used; one was on work orientation and the other on performance. After completion of the surveys, six participants were invited to participate in an in-depth interview. The participants were aligned with the calling orientation and had a high performance at work. They described their work as integrated into their lives, involving their families in decisions, helping people, and desiring to make a difference in this world. Also, the findings showed that people who live a calling feel that work and life have intertwined meanings. The motivation, well-being, connection with an organization, engagement with work, and having a purpose were factors that had significance for those who perceive work as a calling. The main results were that the participants faced new challenges, built new meanings and understandings about work during their careers. Each experience helped them to improve the next, while also improving their performance. The relationship between these factors revealed a cycle of meanings. The cycle represents the evolution of the creation of new meanings which defines how people perceive their work and how that influences performance. Furthermore, this study showed that it is possible to change the perception of work through goals, achievement, working context, the adversities faced, stages of life, and the work environment. All of these lead to new meanings and becoming aligned to different dimensions of work orientation.

Full textAbstract:
Grounded in Green and Kreuter's (1991) flexible research framework (the PRECEDE model), the prime purpose of this doctoral research agenda has been to enhance our understanding of the frequently obscure psychosocial implications of ageing with hearing handicap (HH) in the audible world, by focusing on the dyadic perspectives of older New Zealand (NZ) ex-service personnel and their spouses. Glass and Balfour's (2003) Ecological Model of Ageing guided the multidisciplinary literature review, in order to accommodate the functional implications of age-related losses which could potentially exacerbate the social and emotional sequelae of ageing with HH and tinnitus. In addition, Cohen's (1992) Transactional Model of Stress (which integrates three social support constructs with Lazarus and Folkman's [1984] model describing adaptations to stressful events), illustrates how on-going social and emotional adjustments to hearing losses could potentially affect older adults' health-related quality of life (H-QoL). Infused by these transdisciplinary ecological perspectives, a composite model of Ageing with Hearing Handicap was proposed to explore older dyadic partner perspectives of NZ veterans' adjustment to ageing with hearing handicap; and to identify which factors exerted the most influence over the veterans' self-reported perceptions of HH and H-QoL. Methods: A purposive pilot study sample (N=51 veterans) initially guided the appropriate selection of ecologically relevant biopsychosocial variables and data collection methods (self-report mail out booklets) for two subsequent studies: (i) The main 'parent' study (referred to as the Hearing Aid Research Project [HARP]), which examined the predictors of hearing aid use in veterans aged 50 year and older; and (ii) The doctoral study, which explored dyadic perspectives of ageing with HH. The doctoral study's dyadic partner sample (N=671 dyads) comprised a subset of the 1249 HARP veterans. This subset met the doctoral study's inclusion criteria of male veterans aged 65 years plus, who had responded with a female partner/spouse residing in the same household. Only dyads with reasonably complete mail out survey response sets were selected. The dyadic partner response sets included social demographic details and responses to a number of constructs relevant to the doctoral research context including: aural rehabilitation, HH, H-QoL, emotional wellbeing, social support and memory in everyday life. Results: The results describe significantly different aural rehabilitation coping trajectories between the self-identified 'first time' and more experienced hearing aid users; and dyadic partner comparisons which highlight that the female partners were more acutely aware of the stigmatising impact of hearing losses on the veterans' social and emotional agency. Analyses of the intersecting structural and functional features of social support illustrated that increasing levels of the veterans' hearing handicap (HH) exacerbated both partners' social isolation. Wenger's (1994) support network typology illustrated how both partners' depressive symptoms and the veterans' frequency of forgetting increased significantly across a socially integrated to isolated support network continuum. The composite model of Ageing with Hearing Handicap accounted for 71.5% of the variation in the veterans' self-reported HH; 62.6% of their physical and 37.3% of their mental H-QoL. The multivariate analyses also demonstrated that HH produced a direct and negative impact on the veterans' mental H-QoL, by constraining their social and emotional agency; but only indirectly on their physical H-QoL, through reducing their energy levels and constraining their social participation. Conclusions: These transdisciplinary perspectives provide cross-sectional insights about the social and emotional wellbeing of veterans ageing with HH and their spouses, and suggest downstream links that affect their H-QoL. These findings highlight the importance of hearing health policy agendas and the communication contexts of health service delivery across all age groups. Moreover, by resolving the complex methodological and conceptual challenges inherent in focussing on older dyadic partners' everyday experiences, targets have become apparent for further investigation, to enhance and refine our understandings of engaging ecological perspectives when conducting health research.

Full textAbstract:
The monitoring-blunting theory of coping in threatening situations (Miller, 1981, 1987) suggests that when faced with a threatening situation, individuals can respond either by attending to threatening information (―monitoring‖) or by avoiding threatening information (―blunting‖). A valid and reliable measure of children’s preferred coping styles in dental situations may assist dental staff in providing efficacious anxiety-reducing interventions to diverse groups of children. The current study sought to validate a scale of children’s preference for monitoring or blunting in dental situations (the Monitoring Blunting Dental Scale or MBDS). The psychometric characteristics of the scale were assessed in a group of 240 eleven to thirteen year old New Zealand children. Internal consistency reliability was adequate for both the monitoring ( = .743) and blunting ( = .762) subscales. Convergent validity was indicated by strong correlations (> .6) between the MBDS monitoring and blunting subscales and those of an adapted version of the Child Behavioural Style Scale (CBSS-M). Discriminant validity with respect to dental anxiety was strong for the monitoring subscale, r = .079, p = .221, but not the blunting subscale, r = .478, p <.001. Confirmatory factor analysis of the MBDS indicated adequate fit for a two factor monitoring-blunting model (RMSEA = .079), but unacceptable fit for a one factor model (RMSEA = .095). A similar finding was observed when confirmatory factor analysis of the CBSS-M was conducted. These confirmatory factor analyses suggested that the monitoring and blunting theoretical constructs cannot be justifiably regarded as representing poles of a single underlying dimension, but are better regarded as distinct, related constructs. A content analysis of children’s comments about the coping strategies they might adopt in several dental scenarios indicated that these strategies were largely classifiable within monitoring-blunting theory, with blunting-type strategies much more commonly mentioned. Given further validity evidence, the MBDS could be a useful measure when attempting to tailor anxiety-reducing interventions in dental settings to children with diverse coping preferences.

The link between volatile organic compounds (VOCs) from breath and various diseases and specific conditions has been identified since long by the researchers. Canine studies and breath sample analysis on Gas chromatography/ Mass Spectroscopy has proven that there are VOCs in the breath that can detect and potentially predict hypoglycemia. This project aims at developing a smart nanosensor system to detect hypoglycemia from human breath. The sensor system comprises of 1-Mercapto-(triethylene glycol) methyl ether functionalized goldnanoparticle (EGNPs) sensors coated with polyetherimide (PEI) and poly(vinylidene fluoride -hexafluoropropylene) (PVDF-HFP) and polymer composite sensor made from PVDF-HFP-Carbon Black (PVDF-HFP/CB), an interface circuit that performs signal conditioning and amplification, and a microcontroller with Bluetooth Low Energy (BLE) to control the interface circuit and communicate with an external personal digital assistant. The sensors were fabricated and tested with 5 VOCs in dry air and simulated breath (mixture of air, small portion of acetone, ethanol at high humidity) to investigate sensitivity and selectivity. The name of the VOCs is not disclosed herein but these VOCs have been identified in breath and are identified as potential biomarkers for other diseases as well.
The sensor hydrophobicity has been studied using contact angle measurement. The GNPs size was verified using Ultra-Violent-Visible (UV-VIS) Spectroscopy. Field Emission Scanning Electron Microscope (FESEM) image is used to show GNPs embedded in the polymer film. The sensors sensitivity increases by more than 400% in an environment with relative humidity (RH) of 93% and the sensors show selectivity towards VOCs of interest. The interface circuit was designed on Eagle PCB and was fabricated using a two-layer PCB. The fabricated interface circuit was simulated with variable resistance and was verified with experiments. The system is also tested at different power source voltages and it was found that the system performance is optimum at more than 5 volts. The sensor fabrication, testing methods, and results are presented and discussed along with interface circuit design, fabrication, and characterization.

Vehicle automation is developing at a rapid rate worldwide. However, even lower levels of automation, such as SAE Level-1, are expected to reduce drivers’ workload by controlling either speed or lane position. At the same time, however, drivers’ engagement in secondary tasks may make up for this difference in workload displaced by automation. Previous research has investigated the effects of adaptive cruise control (ACC) on driving performance and workload, but little attention has been devoted to Lane Keeping Systems (LKS). In addition, the influence of secondary cognitive tasks on Level-1 driving performance is also not well understood.
The first goal of this thesis study was to examine the effects of secondary cognitive tasks and driving condition on driving performance. The second goal was to examine the effects of secondary cognitive tasks and driving condition on heart rate related measurements that reflect changes in workload. Both a novel nano-sensor and a commercial ECG sensor were used to measure heart rate. Thus, the third goal was to compare the capability of a nano-sensor in detecting changes in heart rate and heart rate variability with a commercially available ECG sensor. Twenty-five participants drove a simulated vehicle in manual, ACC and LKS driving conditions, while performing a secondary cognitive (N-back) task with varying levels of difficulty.
Results showed that more difficult cognitive secondary tasks were beneficial to driving performance in that a lower standard deviation of lane departure (SDLD) and a lower standard deviation of vehicle speed (SDVS) were both observed. Heart rate and NASA-TLX workload scores were significantly higher in the most difficult secondary task and in the manual driving conditions. However, heart rate variability measures (SDNN, RMSSD, pNN50, LF Power and HF Power) indicated lower variability under more difficult secondary tasks. This thesis suggests that nanotechnological devices may serve as a potential alternative to other heart rate measuring technology. Limitations in detecting minor heart rate changes between different driving conditions and in heart rate variability measuring were also acknowledged.

Full textAbstract:
The concept of shape is widely used by musicians in talking and thinking about performance, yet the mechanisms that afford links between music and shape are little understood. Work on the psychodynamics of everyday life by Daniel Stern and on embodiment by Mark Johnson suggests relationships between the multiple dynamics of musical sound and the dynamics of feeling and motion. Recent work on multisensory and precognitive sensory perception and on the role of bimodal neurons in the sensorimotor system helps to explain how shape, as a percept representing changing quantity in any sensory mode, may be invoked by dynamic processes at many stages of perception and cognition. These processes enable ‘shape’ to do flexible and useful work for musicians needing to describe the quality of musical phenomena that are fundamental to everyday musical practice and yet too complex to calculate during performance.

Full textAbstract:
Abstract The spectral attitude toward composition that emerged in France in the 1970s and 1980s was intimately related to the creative processes of performers, their practices, and their perceptions. The composers associated with L’Itinéraire in its early years—Tristan Murail, Gérard Grisey, Michaël Lévinas, Hugues Dufourt, and Roger Tessier—were performing musicians themselves, and their experiences contributed to their pre-occupation with timbre, temporality, process, and perception. Expressing an ecological perspective, they saw the performer as an integral part of the sensory environment, and of the ensemble energies and forces effecting the animation of acoustic phenomena. The “pure becoming of sound” could only be conveyed through the pure becoming of a performance, requiring a highly disciplined performer dedicated to processes of synthesis and transformation. Locating the performance practice of spectral music historically leads to a consideration of virtuosity and physicality in relation to Romantic, aleatoric, and New Complexity repertoire, and also to the work of post-spectralists Jonathan Harvey and Georg-Friedrich Haas.

Most design interventions manipulate the environment to convey sensory information to the public. However, aside from cosmetic industry, research on the olfactory modality has been broadly overlooked. Being one of the most ancient senses, smell provides motivational guidance within the environment, and some evidence has pointed to multisensory influences of smell. Thus, if the olfactory experience could surpass its mere perception and extend to our decisions, it would become a critical topic for design R&D. We assessed the influence of environmental smells on the performance of two distinct decision tasks, namely, a parallel response selection / conflict monitoring task (see Beste et al. 2013) and a cocoa taste-discrimination task, respectively employing an orthonasal (experiment 1) and a retronasal (experiment 2) smell exposure. Three identical laboratory rooms were used in both experiments to expose the participants to control, pleasant (apple fragrance scented room), and unpleasant (faecal / putrid room) smells in a counterbalanced within-subject design. Although participants’ response times were equivalent between conditions in experiment 1, the unpleasant room was associated with a decreased (albeit non-significant) number of errors. Remarkably, experiment 2 revealed that the unpleasant smell condition produced significantly more accurate judgments about the cocoa content of the trials than those obtained under pleasant (p< 0.01) and control (p< 0.05) conditions. Our findings are discussed considering the salience of smells (i.e., motivational value), and task demands (i.e., exposure length and type of cognitive processes engaged). Those factors likely combine to determine the resources (e.g., attention) allocated at each task and consequently, the degree of interference that smells could have on decision-making. We argue that olfactory design interventions might benefit those people in various contexts where sharp decisions are an asset (e.g., operating rooms, court rooms, etc).

Full textAbstract:
Patient-centered care (PCC) approaches are critical for the delivery of high-quality care in cancer care where the therapeutic alliance between patients and the oncologists is frequent over extended periods of time. The concept of patient-centered care has received increased attention since the publication of the 2001 Institute of Medicine (IOM) report Crossing the Quality Chasm. In this study, we create and evaluate a new framework for patient-centered care in cancer using human factors approaches. Many initiatives focused on developing technologies that help foster PCC by increasing patients’ access to information and facilitating self-monitoring and patient convenience. This paper makes an important contribution to the literature by historically examining the evolution of the definitions of care approaches from disease-centered care focusing on curing the diseases to patient-centered care satisfying patients’ needs to person-centered care. Instead of treating people like victims of diseases, this model recognizes their need for more than one professional to support them emphasizing their capabilities and potential to improve their own health by themselves. It also provides a different and complementary way to the visit-oriented approach furnishing more accessible and continuous care over time, Our contribution also covers summarizing the existing measures adopted to measure its components and finally suggests a socio-technical framework based on the human factors approach to measuring PCC effectiveness. Our approach to measuring PCC is grounded in the conceptual framework we are suggesting that evaluates the effectiveness of patient-centered care based on a socio-technical perspective. We link the cognitive perception of patients towards PCC (Cognitive Sensory Input) to their exposure to external factors (Exposure) that may affect their (Cognition) behavior. A holistic approach recognizing health care as a dynamic socio-technical system in which sub-elements interact with each other remains necessary to better understand the system and its constraints in cancer care. We use a case study to emphasize the importance and need of such a human factors-based framework in providing a better quality of care and improving health outcomes. Achieving high-quality care is a complex pursuit in any setting especially for cancer care and improving the patient journey requires an integrated system of care and productive interactions among many system levels. By understanding the work system components, the design and integration of tasks, technology, and clinical processes can be reviewed to better support the respective needs of individuals while optimizing system performance. A supportive work environment and a highly engaged workforce are highly correlated with improved quality of patient-centered care and hospital performance. At the population level, case managers, navigators, quality officers, and administrators may track outcomes across patients.This framework can help organize clinical interventions that aim to control cancer patients’ behavior from a patient-centered perspective. It can also help technology designers by giving them insight into how patient-centeredness in the design of health informatics can impact cancer patients’ behavior. In addition, patient-centered designs can enhance technology acceptance among cancer patients making it easier to adopt technology for follow-up reasons by involving human factors and ergonomics principles in order to ensure successful results.
