Working Memory and Cognitive Skills in Individuals with Down Syndrome

This work is aimed at analyzing working memory (WM) components and their relationships with other cognitive processes in individuals with Down syndrome (DS). Particular attention is given to examine whether a verbal WM deficit is due to difficulties in verbal abilities often showed by individuals with DS, or whether it is a deficit per se. A group of 20 individuals with DS was compared to a group of 20 typically developing (TD) children matched on vocabulary comprehension and to a group of 20 TD children matched on general verbal intelligence. The groups received a battery of 3 verbal and 3 visuospatial WM tasks requiring different degrees of control, and tests assessing verbal abilities (WPPSI verbal scale, PPVT), nonverbal skills (WPPSI performance scale), and logical thinking (LO). The results revealed that individuals with DS have deficits in both central executive (control) and verbal components of the WM system, and the latter one is independent of the general verbal abilities deficit. The data suggest that the development of central executive proceeds at a slower rate in individuals with DS and differently from TD children with comparable verbal abilities. The performance of individuals with DS on high-control WM tasks requires additional general resources that are strictly linked to intelligence.     

Can a communitarian concept of African personhood be both relational and gender-neutral?

This paper explores the relationship between the African communitarian conception of personhood and gender. Defenders of this conception of personhood generally hold that an individual is defined in reference to the community, or that personhood is something that is acquired in community. Such characterisations often ignore the role, if any, that gender plays in that conception of personhood. Our aim in this paper is to critically explore the relationship between the two. In doing this we advance a number of claims. First, we point out that the supposed gender-neutrality of the African communitarian idea of personhood is a more general feature of African philosophy that, for instance, evinces a general lack of attention to issues of gender violence and discrimination. Second, we briefly survey the literature on the communitarian idea of personhood in African thought, in particular the views of Ifeanyi Menkiti and Kwasi Wiredu. Our aim is to demonstrate our hypothesis that this idea of personhood is often construed as a gender-neutral concept. Third, we argue that the relational and community-based nature of the communitarian idea of personhood indicates that it is in fact a gendered notion. We conclude that the assumed gender-neutrality is in conflict with the gendered nature of the communitarian idea of personhood. Fourth, we explore a probable objection to our claim that the communitarian idea of personhood is gendered and therefore vulnerable to gender inequality, by examining Ifi Amadiume's position that the notion of gender in traditional African cultures was fluid and indicated complementarity rather than inequality between the sexes. We argue that Amadiume's case is not convincing.     

Using stressful films to analyze risk factors for PTSD in analogue experimental studies – which film works best?

Abstract

To understand mental disorders, analogue paradigms provide an indispensable contribution. In posttraumatic stress disorder (PTSD), the stressful film paradigm is a frequently used analogue approach: Films depicting traumatic events are shown to non-clinical participants in order to elicit stress responses analogue to responses to traumatic events in real life. Previous studies used a large variety of films, which is problematic with regard to the comparability of results. The main goal of this study was to identify a film clip that (a) consistently provokes stress reactions and (b) provokes reactions that are as similar as possible to traumatic stress.

We randomly exposed 105 male and female participants to one of four stressful films, differing, e.g., in content and origin. Intrusive memories of the film, reported immediately after the film and during a diary phase of three days, as well as distress, heart rate, and several mood states were measured. A film clip depicting rape elicited the most consistent reactions that were characterized by a higher heart rate, more distress and more intrusive memories, compared to the other three clips. Intrusive memories across all films were especially related to an increase in heart rate and disgust in response to the film.     

Love as a Fictitious Commodity: Gift-for-Sex Barters as Contractual Carriers of Intimacy

Gift-for-sex (GFS) barters are a niche practice potentially representing the commodification of everyday dating practices. We inquire how GFS exchanges are practiced and understood in contemporary Russia. Second, we situate these in relation to contemporary economic culture. Our project provides answers in two steps based on online content. First, we identify GFS exchange practices within a major dating website. Next, we take the signals exchanged in those dating profiles and display their intersubjective meanings in Russia based on blogs and discussion fora. Our analysis focuses on gender roles and inter-gender conflicts, the use of economic jargon, the link between luxury consumption and sexuality, and understandings of gift-giving and generosity, in order to show how GFS barters, despite being contractual, carry emotional and romantic content. As such, love is under a constant conversion process, through the medium of the contractual gift, into the fictitious commodity form.     

Spatial Working Memory in Aging and Mild Cognitive Impairment: Effects of Task Load and Contextual Cueing

ABSTRACT

Mild Cognitive Impairment (MCI) is characterized by episodic memory deficits, while aspects of working memory may also be implicated, but studies into this latter domain are scarce and results are inconclusive. Using a computerized search paradigm, this study compares 25 young adults, 25 typically aging older adults and 15 amnestic MCI patients as to their working-memory capacities for object-location information and potential differential effects of memory load and additional context cues. An age-related deficit in visuospatial working-memory maintenance was found that became more pronounced with increasing task demands. The MCI group additionally showed reduced maintenance of bound information, i.e., object-location associations, again especially at elevated memory load. No effects of contextual cueing were found. The current findings indicate that working memory should be considered when screening patients for suspected MCI and monitoring its progression.     

Genetic Counseling/Consultation in South-East Asia: A Report from the Workshop at the 10th Asia Pacific Conference on Human Genetics

This paper reports on the workshop ‘Genetic Counseling/Consultations in South-East Asia’ at the 10^th Asia Pacific Conference on Human Genetics in Kuala Lumpur, Malaysia, in December 2012. The workshop brought together professionals and language/communication scholars from South-East Asia, and the UK. The workshop aimed at addressing culture- and context-specific genetic counseling/consultation practices in South-East Asia. As a way of contextualizing genetic counseling/consultation in South-East Asia, we first offer an overview of communication-oriented research generally, drawing attention to consultation and counseling as part of a communicative continuum with distinctive interactional features. We then provide examples of genetic counseling/consultation research in Hong Kong. As other countries in South-East Asia have not yet embarked on communication-oriented empirical research, we report on the current practices of genetic counseling/consultation in these countries in order to identify similarities and differences as well as key obstacles that could be addressed through future research. Three issues emerged as ‘problematic’: language, religion and culture. We suggest that communication-oriented research can provide a starting point for evidence-based reflections on how to incorporate a counseling mentality in genetic consultation. To conclude, we discuss the need for creating a platform for targeted training of genetic counselors based on communication-oriented research findings.     

Factors Predicting Likelihood of Eating Irradiated Meat

Perception of risk associated with meat irradiation was investigated in a sample of 478 respondents. Fears associated with irradiation, the relative severity and risk of bacterial infection versus potential risks due to the irradiation, and perceptions of the safety of the meat irradiation process combined to strongly predict participants' reports of their likelihood of eating irradiated meat in the present investigation. Overall, respondents were skeptical with regard to eating irradiated meat if it became locally available. Respondents' acceptance of meat irradiation was clearly driven by concerns about the risks of irradiation, but not the risks of bacterial contamination, confirming findings in the literature on differences in perception of “natural” and “technological” risks.     

Color Preference and Food Choice Among Children

The effects of color on children's food choices were investigated. Subjects were 120 children who were equally distributed among each of the combinations of age (5 vs. 9 years old), sex (male vs. female), food type (3 types of candies), and color (red, green, yellow, and orange) in a counterbalanced, factorial, analysis-of-variance design with repeated measures on subjects. A significant main effect for color indicated that children preferred foods that were red, green, orange, and yellow, in that order. Interpretation of this main effect was not interfered with by main effects or interaction terms involving age, sex, or food type, which served as alternative rival hypotheses.     

Powerful Occupational Therapists: A Community of Professionals, 1950–1980

A powerful community of therapists changed occupational therapy in the United States between 1950 until 1980. These innovators, primarily women, strategically positioned themselves to market the emerging profession. These therapists, categorized as theorists and futurists, political movers and new and old guard sustainers, determined occupational therapy's direction. Participating in the 1950s rehabilitation, the 1960s equal rights, and the 1970s women's movements, the community of therapists separated from the male-dominated medical model to gain professional and scientific authority. An internal tension arouse between those therapists embracing an objective, and arguably male, science and those supporting a characteristically feminine caring philosophical base.     

The visuospatial functions in children after cerebellar low‐grade astrocytoma surgery: A contribution to the pediatric neuropsychology of the cerebellum

The aim of this study was to specify whether cerebellar lesions cause visuospatial impairments in children. The study sample consisted of 40 children with low‐grade cerebellar astrocytoma, who underwent surgical treatment and 40 healthy controls matched with regard to age and sex. Visuospatial abilities were tested using the spatial WISC‐R subtests (Block Design and Object Assembly), Rey–Osterrieth Complex Figure, Benton Judgment of Line Orientation Test, PEBL Mental Rotation Task, and Benton Visual Retention Test. To exclude general diffuse intellectual dysfunction, the WISC‐R Verbal Intelligence IQ, Performance IQ, and Full‐Scale IQ scores were analysed. Post‐surgical medical consequences were measured with the International Cooperative Ataxia Rating Scale. Compared to controls, the cerebellar group manifested problems with mental rotation of objects, visuospatial organization, planning, and spatial construction processes which could not be explained by medical complications or general intellectual retardation. The intensity of visuospatial syndrome highly depends on cerebellar lesion side. Patients with left‐sided cerebellar lesions display more severe spatial problems than those with right‐sided cerebellar lesions. In conclusion, focal cerebellar lesions in children affect their visuospatial ability. The impairments profile is characterized by deficits in complex spatial processes such as visuospatial organization and mental rotation, requiring reconstruction of visual stimuli using the imagination, while elementary sensory analysis and perception as well as spatial processes requiring direct manipulation of objects are relatively better preserved. This pattern is analogous to the one previously observed in adult population and appears to be typical for cerebellar pathology in general, regardless of age.
