Virtual reality in the rehabilitation of the upper limb after stroke: the user's perspective.

Our group has developed a relatively low-cost virtual reality (VR) system for rehabilitation of the upper limb following stroke. Our system is immersive in that the participant views a representation of their arm and hand, reaching and retrieving objects in the virtual environment (VE), through a head-mounted display (HMD). This is thought to increase the participant's sense of presence in the VE and may lead to improved rehabilitation outcomes. However, use of immersion, particularly with our low-cost system, may increase the incidence of side effects reported. Therefore, the aim of this project was to assess the interaction of healthy users and those following stroke, in terms of their experience of presence in the VE and the rate of self-reported side effects. Differences in rates of perceived exertion, levels of enjoyment, and sense of control between both groups were also explored.     

The locus of semantic priming effects in person recognition

Semantic priming in person recognition has been studied extensively. In a typical experiment, participants are asked to make a familiarity decision to target items that have been immediately preceded by related or unrelated primes. Facilitation is usually observed from related primes, and this priming is equivalent across stimulus domains (i.e., faces and names prime one another equally). Structural models of face recognition (e.g., IAC: Burton, Bruce, & Johnston, 1990) accommodate these effects by proposing a level of person identity nodes (PINs) at which recognition routes converge, and which allow access to a common pool of semantics. We present three experiments that examine semantic priming for different decisions. Priming for a semantic decision (e.g., British/American?) shows exactly the same pattern that is normally observed for a familiarity decision. The pattern is equivalent for name and face recognition. However, no semantic priming is observed when participants are asked to make a sex decision. These results constrain future models of face processing and are discussed with reference to current theories of semantic priming.     

The Training and Supervisory Needs of Racial and Ethnic Minority Students

Despite the increasing attention given to issues of multicultural training in counseling programs, there is a dearth of information available on the unique training needs of racial and ethnic minority trainees. The authors review the sparse literature relevant to the training needs of ethnic minority students, offer examples of training and supervisory issues, and make recommendations for future research and training.     

In the Dock: Chimeric Image Composites Reduce Identification Accuracy

The aim of presenting chimeric images (formed from opposing halves of a pair of same or different faces) in court settings is to optimise the accuracy of identification decisions based on CCTV evidence. The experiments reported here examined the utility of this technique. Experiment 1 examined the accuracy of face matching with vertically split, aligned chimeric images, misaligned hemi‐faces and full‐face images. Experiment 2 replicated the first experiment but replaced the misaligned images with opposing hemi‐faces separated by a gap. The final experiment used horizontally split faces. All three experiments showed that matching was less accurate with aligned chimeric images than with full‐face images. Furthermore, the pattern of responses obtained with chimeric images differed significantly from full‐face matching and misaligned/separated hemi‐face matching. Chimeric images produced a bias towards same responses even when the face halves were different. The results suggest caution in the use of chimeric images in court.

Mother's choice: An exploration of extended self in infant clothing consumption

Consumption behaviour has long been linked to identity and notions of the self, where materialistic behaviours and attitudes are seen as determinants of self‐image. Previous literature has focused on mothers' consumption in general, but not specifically in regard to identity construction through purchasing for an infant. There is a dearth of academic research understanding mothers' consumption behaviour that links identity construction with infant clothing, where the child is part of the mothers' extended self and display of self‐identity. This qualitative, exploratory study provides insight into how mothers construct and express their identity through the extended self, contributing to consumer culture theory. The study examines the purchasing motivations of 14 mothers, utilizing depth interviews and projective association techniques. The findings indicate three predominant drivers underlying mothers' consumption, namely prioritizing the child, self‐representation and conspicuous branding.

Historical Perspectives on Global Ecology

A historical perspective can shed light on the dilemmas and dimensions of current ecological predicaments. Consideration of long-term trends in economic, demographic, and energy history show just how peculiar, disruptive, liberating, and unsustainable modern times have been. The current era of ecological tumult derives its impetus from many sources, not least the near-stasis in ideas and politics. It is the big ideas, like nationalism, communism, or the premium placed on economic growth, rather than explicitly environmental ideas, that most affected environmental policy and outcomes in the 20th century, and will likely continue to do so in the 21st.
