Multisensory self‐motion encoding in parietal cortex

Navigation through the environment requires the brain to process a number of incoming sensory signals, such as visual optical flow on the retina and motion information originating from the vestibular organs. In addition, tactile as well as auditory signals can help to disambiguate the continuous stream of incoming information and determining the signals resulting from one's own set of motion. In this review I will focus on the cortical processing of motion information in one subregion of the posterior parietal cortex, i.e., the ventral intraparietal area (VIP). I will review (1) electrophysiological data from single cell recordings in the awake macaque showing how self‐motion signals across different sensory modalities are represented within this area and (2) data from fMRI recordings in normal human subjects providing evidence for the existence of a functionally equivalent area of macaque area VIP in the human cortex.     

Structural equation modelling of human judgement

Structural equation modelling (SEM) is outlined and compared with two non-linear alternatives, artificial neural networks and “fast and frugal” models. One particular non-linear decision-making situation is discussed, that exemplified by a lexicographic semi-order. We illustrate the use of SEM on a dataset derived from 539 volunteers' responses to questions about food-related risks. Our conclusion is that SEM is a useful member of the armoury of techniques available to the student of human judgement: it subsumes several multivariate statistical techniques and permits their flexible combination, and it provides robust goodness-of-fit statistics and is available in (generally) easy-to-use computer packages. Although the number of tasks for which SEM provides a persuasive psychological model is small, it is very useful in identifying the important variables and their inter-relations that contribute to task performance, and thus can constitute a valuable intermediate staging point between raw data and a fully fledged psychological theory.     

Reassessing the Work Ethic: A New Look at Work and Other Activities

Abstract

The aim of this paper is to argue that psychological research on the work ethic, or work centrality, uses too narrow a focus for understanding shifts in behaviour and attitudes over time. The appropriate unit of analysis is activity. Working is a subcategory of this larger unit. Six areas of activity are distinguished: education and training in early life, paid tasks or work, updating education throughout life, unpaid tasks or voluntary activity, education of the third age, and active or passive leisure. Historical, sociological, and anthropological evidence is reviewed and related to the psychological analysis of the meaning of working. It emerges that work is a controversial topic; it is extensively praised by some and condemned by others. Few would deny that paid work is a necessary way of obtaining basic and supplementary human requirements under present-day circumstances, but the differential conditions and constraints under which it is carried out are not always accepted as a necessary corollary. Is paid work a necessary or a desirable means of obtaining a standard of living? The answer depends on whether paid work is seen in isolation or as a subsystem of a wider range of activities which together result in a fulfilling life.     

Hornsby and Baker on the physicalist orthodoxy

I examine some recent claims put forward by L. A. Paul, Barry Dainton and Simon Prosser, to the effect that perceptual experiences of movement and change involve an (apparent) experience of ‘passage’, in the sense at issue in debates about the metaphysics of time. Paul, Dainton and Prosser all argue that this supposed feature of perceptual experience – call it a phenomenology of passage – is illusory, thereby defending the view that there is no such a thing as passage, conceived of as a feature of mind-independent reality. I suggest that in fact there is no such phenomenology of passage in the first place. There is, however, a specific structural aspect of the phenomenology of perceptual experiences of movement and change that can explain how one might mistakenly come to the belief that such experiences do involve a phenomenology of passage.     

Disability Cosmology: The Practice of Making Disability Worlds

The practice of making disability worlds is investigated both theoretically, in the context of developments in disability studies, in particular in the cultural model of disability, and practically in two examples, namely inclusive education environments and public environments. Theoretically, we argue that disability worlds can be better understood by introducing the notion of disability cosmology as the largest possible perspective on the making of disability worlds. A cultural model research perspective of disability consists then of the complementary study of disability identity, culture and cosmology. The practical examples work out the particularities of making and understanding disability worlds. In the making of disability worlds, much attention goes to the ways in which disability worlds relate to the normative world; for example in the formation of boundaries and transgressions, but also fundamentally how disability adds to becoming human.     

Adolescents who need help the most are the least likely to seek it: the relationship between low emotional competence and low intention to seek help

It has been found that university students who were the least skilled at managing their emotions also had the lowest intention of seeking help from a variety of nonprofessional sources (e.g. family and friends). The present study sought to extend these findings by focusing on adolescents, examining a larger number of emotional competencies, and exploring the possibility that social support explains the relationship between emotional competence and help-seeking. A total of 137 adolescents (aged 16-18) completed an anonymous survey that assessed social support, emotional competencies, and intention to seek help from a variety of professional and nonprofessional sources. As expected, adolescents who were low in emotional awareness, and who were poor at identifying, describing, and managing their emotions, were the least likely to seek help from nonprofessional sources and had the highest intention of refusing help from everyone. However, low emotional competence was not related to intention to seek help from professional sources (e.g. mental health professionals). The significant results involving nonprofessional sources were only partially explained by social support, suggesting that even adolescents who had high quality support were less likely to make use of that support if they were low in emotional competence.     

The Role of Virtual Experience in Consumer Learning

Through a series of studies designed to explore important aspects of virtual experience, a new type of product affordances—virtual affordances—is proposed and tested empirically. In addition, the existing geometric and material product taxonomy is extended to include mechanical products within the classification structure. Utilizing these new concepts, 3‐D product visualization is compared with traditional 2‐D product representations and television advertising. The results largely support the proposition that 3‐D product visualization is capable of influencing brand attitude and purchase intention for geometric and mechanical products within e‐commerce environments.     

Relations between social and emotional competence and mental health: a construct validation study

Researchers working fairly independently of each other have created numerous measures of social and emotional competence (SEC). These measures tend to correlate (sometimes highly) with each other and with measures of stressful events, suggesting potential redundancy. We evaluated which, if any, SEC variables predicted unique variance in social and mental health after controlling for other SEC variables in the study and the impact of stressful events. Three-hundred and thirty-one university students participated in an anonymous, cross-sectional study. We measured stressful events, and a wide variety of SECs, including: social problem solving skill (effective problem orientation, automatic processing, and problem solving), alexithymia (difficulty identifying and describing emotions; minimising emotions), effective emotional control (low rumination, high impulse control, high aggression control, low defensive inhibiting of emotions), and level of emotional awareness. We also assessed a variety of aspects of social and mental health (e.g. depression, anxiety, hopelessness, suicidal ideation, life satisfaction, social support). Covariance analyses revealed that all SEC measures except minimising emotions had significant incremental value over the other measures and over stressful events in predicting social and mental health. The optimal set of predictors differed depending upon the type of health predicted. These findings have important implications for the design of social and emotional intervention programs.
