Vulnerability of facial attractiveness perception to early and multi-year visual deprivation

Judgments of facial attractiveness invariably accompany our perception of faces. Even neonates appear to be capable of making such judgments in a manner consistent with adults. This suggests that the processes supporting facial attractiveness require little, if any, visual experience to manifest. Here we investigate the resilience of these processes to several years of early-onset visual deprivation. Specifically, we study whether congenitally blind children treated several years after birth possess the ability to rate facial attractiveness in a manner congruent to normally sighted individuals. The data reveal significant individual variability in the way each newly sighted child perceives attractiveness. This is in marked contrast to data from normally sighted controls who exhibit strong across-subject agreement in facial attractiveness ratings. This variability may be attributable, in part, to atypical facial encoding strategies used by the newly sighted children. Overall, our results suggest that the development of facial attractiveness perception is likely to be vulnerable to early visual deprivation, pointing to the existence of a possible sensitive period early in the developmental trajectory.     

Materialism and Fashion Consciousness: The Moderating Role of Status Consumption Tendencies and Religiosity

Understanding whether materialistic values translate directly into fashion consciousness or whether it is the status consumption and religiosity that intensifies this relationship within the specifics of explicitly religious consumers is important as fashion consumption appears to occupy a focal position both socially and economically in the lives of many. The Islamic fashion clothing market has begun to attract recent attention and is becoming an area of interest in consumer research. The Turkish Islamic fashion clothing consumptionscape that reached a yearly sales volume of $39 billion in 2013 within a $266 billion global market shows that the explicitly Muslim Turkish consumer gains excitement and pleasure from keeping up‐to‐date with fashion. Utilizing a unique data set from a survey in Istanbul this article examines the relationships between materialism, status consumption tendencies, intrinsic religiosity, and fashion‐novelty consciousness. Strong evidence is found for the positive relationship of materialism to fashion‐novelty consciousness. In addition, intrinsic religiosity has been identified to have a negative moderating effect on the materialism‐fashion‐novelty consciousness association.     

Exercise Training for Persons with Alzheimer's Disease and Caregivers: A Review of Dyadic Exercise Interventions

Alzheimer's disease (AD) is the most common form of dementia and the prevalence will increase dramatically in the next decades. Although exercise has shown benefits for people with dementia due to AD as well as their caregivers, the impact of a dyadic exercise intervention including both groups as study participants remains to be determined. The authors review the current clinical evidence for dyadic exercise interventions, which are exercise regimens applied to both the person with dementia and the caregiver. A total of 4 controlled trials were reviewed. This review shows that dyadic exercise interventions are feasible and may produce a positive effect on functional independence and caregiver burden. However, there was insufficient evidence to support a benefit of dyadic exercise intervention on cognitive performance and on behavioral and neuropsychiatric symptoms in participants with dementia due to AD. A dyadic exercise intervention improves functional independence and caregiver burden. However, there is a need for well-designed randomized controlled clinical trials to confirm these benefits and to investigate several important points such as the effects of a dyadic exercise intervention on cognitive and noncognitive outcomes of AD, the optimal intensity of exercise training, and the cost effectiveness of such a program.     

Ethical Dilemmas at the End of Life: Islamic Perspective

Many Muslim patients and families are often reluctant to accept fatal diagnoses and prognoses. Not infrequently, aggressive therapy is sought by the patient or his/her family, to prolong the life of the patient at all costs. A series of searches were conducted of Medline databases published in English between January 2000 and January 2015 with the following Keywords: End-of-life, Ethics and Islam. Islamic law permits the withdrawal of futile treatment, including all kinds of life support, from terminally ill patients leaving death to take its natural course. However, such decision should only take place when the physicians are confident that death is inevitable. All interventions ensuring patient’s comfort and dignity should be maintained. This topic is quite challenging for the health care providers of Muslim patients in the Western World.     

Why emotion recognition is not simulational

According to a dominant interpretation of the simulation hypothesis, in recognizing an emotion we use the same neural processes used in experiencing that emotion. This paper argues that the view is fundamentally misguided. I will examine the simulational arguments for the three basic emotions of fear, disgust, and anger and argue that the simulational account relies strongly on a narrow sense of emotion processing which hardly squares with evidence on how, in fact, emotion recognition is processed. I contend that the current body of empirical evidence suggests that emotion recognition is processed in an integrative system involving multiple cross-regional interactions in the brain, a view which squares with understanding emotion recognition as an information-rich, rather than simulational, process. In the final section, I discuss possible objections.     

Perceptions of and Attitudes toward Plagiarism and Factors Contributing to Plagiarism: a Review of Studies

The abundance of information technology and electronic resources for academic materials has contributed to the attention given to research on plagiarism from various perspectives. Among the issues that have attracted researchers’ attention are perceptions of plagiarism and attitudes toward plagiarism. This article presents a critical review of studies that have been conducted to examine staff’s and students’ perceptions of and attitudes toward plagiarism. It also presents a review of studies that have focused on factors contributing to plagiarism. Our review of studies reveals that most of the studies on perceptions of plagiarism and attitudes toward plagiarism lack an in-depth analysis of the relationship between the perceptions of plagiarism and other contextual, sociocultural and institutional variables, or the relationship between attitudes toward plagiarism and students’ perceptions of various forms of plagiarism. Although our review shows that various factors can contribute to plagiarism, there is no taxonomy that can account for all these factors. Some suggestions for future research are provided in this review article.     

Aging, Training, and the Brain: A Review and Future Directions

As the population ages, the need for effective methods to maintain or even improve older adults’ cognitive performance becomes increasingly pressing. Here we provide a brief review of the major intervention approaches that have been the focus of past research with healthy older adults (strategy training, multi-modal interventions, cardiovascular exercise, and process-based training), and new approaches that incorporate neuroimaging. As outcome measures, neuroimaging data on intervention-related changes in volume, structural integrity; and functional activation can provide important insights into the nature and duration of an intervention’s effects. Perhaps even more intriguingly, several recent studies have used neuroimaging data as a guide to identify core cognitive processes that can be trained in one task with effective transfer to other tasks that share the same underlying processes. Although many open questions remain, this research has greatly increased our understanding of how to promote successful aging of cognition and the brain.     

Post-training administration of corticosterone enhances consolidation of contextual fear memory and hippocampal long-term potentiation in rats

This study was designed to examine the effect of corticosterone on consolidation of contextual fear memory and hippocampal long-term potentiation (LTP) in rats. In Experiment 1, dose–response effects of corticosterone on consolidation of contextual fear memory were determined. Immediately after training in contextual fear conditioning task, rats received different doses of corticosterone. Testing 24 h later, it revealed that corticosterone enhanced memory consolidation in an inverted U shape as evidenced in increased freezing behavior of corticosterone-treated animals. The most effective dose was 3 mg/kg. In Experiment 2, LTP was examined in rats whose memory consolidation has been enhanced with corticosterone. The rats were trained as the above and received corticosterone (3 mg/kg) immediately after training. Immediately or up to one day after retention test, rats were anesthetized with urethane for LTP experiments. For LTP induction, three episodes of high frequency stimuli, 30 s apart, were delivered to the perforant path, each consisting of 10 stimuli at 250 Hz. LTP was assessed by measuring the increase in the initial slope of the population excitatory post-synaptic potentials and the amplitude of the population spikes. Data indicated that animals whose memory has been enhanced by corticosterone, also displayed enhanced hippocampal LTP. The above findings suggest that glucocorticoids may enhance contextual fear memory consolidation via enhancing hippocampal LTP.
