Directional information and apparent movement

The number of alternative directions that a point of light can take in the apparent movement produced by the successive exposure of two points of light may be considered its directional information. The present experiment is concerned with the relationship between such directional information and the threshold between apparent movement and apparent successiveness, the original hypothesis being that the greater the directional information, the higher the threshold of movement. In fact, contrary results were obtained. Thresholds were obtained under conditions where movement could occur in either eight directions or only in two directions, better and more persistent movement being found under the former conditions. But this result is obtained only when one measures thresholds by an ascending method: increasing the time separation between light points from optimal movement to successiveness. An hypothesis is proposed to explain the findings stated in terms of “attentional disarticulation”.     

Cross-Lagged Relationships Between Insomnia and Posttraumatic Stress Disorder in Treatment-Receiving Veterans

Insomnia is a risk factor for the development of posttraumatic stress disorder (PTSD) while it is also plausible that PTSD symptoms can maintain insomnia symptoms. The present study examined longitudinal bidirectional relationships between insomnia and PTSD symptoms in treatment-seeking veterans. Participants were 693 ex-serving members of the Australian Defence Force who participated in an accredited, hospital-based outpatient PTSD program. Participants completed self-reported assessments of PTSD and insomnia symptoms at four time points: intake, discharge, 3-month, and 9-months posttreatment follow-up.Cross-lagged pathway analyses indicated significant bi-directional pathways between insomnia symptoms and PTSD symptoms at most time points. A final cross-lagged model between insomnia symptoms and the PTSD symptom clusters indicated that the PTSD symptom paths on insomnia symptoms, between intake and discharge, were attributable to reexperiencing PTSD symptoms. In contrast, across posttreatment follow-up time points there were significant paths of insomnia symptoms on all PTSD symptom clusters except from insomnia at 3-months to avoidance symptom at 9-months. PTSD symptoms and insomnia symptoms have bidirectional associations over time that may lead to the mutual maintenance or exacerbation of each condition following PTSD treatment. Where residual insomnia symptoms are present post-treatment, a sleep-focussed intervention is indicated and a sequenced approach to treatment recommended.     

Islamic inheritance in Australia and family provision law: are Sharia wills valid?

This article explains the context of Islamic inheritance and the distinctive nature of what is called in a preliminary sense as ‘Muslim intergenerational property’. The article suggests that a wider view of inheritance should be taken on the basis that inheritance is an intergenerational process that, in the case of Muslims, incorporates religious notions. Secondly, the article describes family provision law and the particular nature of the English transplant of inheritance law into Australia. Thirdly, the article describes the nature of legal services provided to Islamic families and the drafting of Sharia wills. Fourthly, in the light of the law under the State and Federal family provision legislation, the article considers the validity of Islamic wills.     

Medical Psychology in New Zealand

This paper describes medical psychology and health psychology in New Zealand, particularly in relation to psychologists teaching in medical schools, psychologists working in general medical settings, and health psychologists. It identifies a reasonably slow but continuing consolidation of the discipline, particularly from a research perspective, but also with therapeutic initiatives in the public and private health sector. The potential for increased activity in health promotion and increased psychological analysis and influence in the health system is identified.     

Links Between Anxiety and Allergies: Psychobiological Reality or Possible Methodological Bias?

ABSTRACT The objective of the study was to examine the link between anxiety and allergies to establish whether it reflects a psychobiological reality or a possible methodological bias. A cohort of 1,037 children enrolled in the study. Anxiety disorders were assessed between 11 and 21 years. Anxious personality was assessed at 18 years. Allergies were examined at 21 years by (a) self reports, (b) skin pricks, and (c) serum total immunoglobulin E (IgE). Self-reported allergies were predicted by recurrent anxiety disorders (OR [95% CI]=1.56 [1.06–2.30], p =.023) and self-reports of anxious personality (OR [95% CI]=1.67 [1.17–2.37], p =.004): Objectively verified allergies were not. These results suggest that the link between anxiety and allergies may reflect a methodological artifact rather than a psychobiological reality.     

Whither “Confucian Management”?

This article asks whether “Confucian Management” may be seen as the dominant influence in contemporary China. The philosophical legacy of Confucius on modern management theory and practice has received a good deal of attention in recent times, and here I attempt to assess its possible continuity. In order to carry out this task, I apply a bibliometric analysis called the “Culturomics” approach, looking at the literature on “Chinese Management” published in Mandarin in the last century, from 1900 onwards. After the presentation of the empirical data, the discussion section is set out, followed by the article’s conclusions.     

An exploratory investigation of shopper behaviour in an immersive virtual reality store

Shopper research has long been undertaken with physical simulated stores and desktop‐operated virtual stores. However, recent developments in motion‐tracked virtual reality offer a range of new possibilities for research using immersive walk‐around virtual simulated stores. To date, there is little knowledge published on the authenticity of shopper behaviour in such immersive virtual environments. The present study therefore reports exploratory results from 153 multicategory shopping trips conducted in an immersive virtual convenience store. Observed shopper metrics and theoretical effects are compared with equivalent data obtained from published sources and found to be consistent across all measures. Specifically, shoppers purchase a plausible share of private label brands, more private label brands in lower consumption pleasure product categories, more products from higher compared with lower shelf positions, make a plausible proportion of impulsive purchases, and spend less time inspecting familiar versus unfamiliar brands. Further, time in‐store, total spending, and product handling time are higher for women than for men. These exploratory findings show that participants continue to exhibit realistic shopper behaviours in an immersive virtual simulated store. Such stores are therefore a cost‐effective alternative to other methods for measuring consumer behaviour. They offer significant potential for innovative experimental designs in consumer research, as well as potential for future use as a digital shopping channel.
