The hypersocial profile characterizing individuals with Williams syndrome (WS), and particularly their attraction to human faces and their desire to form relationships with other people, could favor the development of their emotion recognition capacities. This study seeks to better understand the development of emotion recognition capacities in WS. The ability to recognize six emotions was assessed in 15 participants with WS. Their performance was compared to that of 15 participants with Down syndrome (DS) and 15 typically developing (TD) children of the same non-verbal developmental age, as assessed with Raven's Colored Progressive Matrices (RCPM; Raven et al...

INTRODUCTION: Internal medicine is an in-hospital speciality. Along with its expertise in rare diseases, it shares with general medicine the global care of patients but its place in the ambulatory shift has yet to be defined. The objective of our work was to evaluate the benefits of an internal medicine day-hospital devoted to general medicine. METHODS: Named "Centre Vi'TAL" to underline the link between the city and the hospital, this novel activity was implemented in order to respond quickly to general practitioners having difficulties to synthesize their complex patients or facing diagnostic or therapeutic problems...

Faces are among the most relevant social stimuli revealing an encounter's identity and actual emotional state. Deficits in facial recognition may be an early sign of cognitive decline leading to social deficits. The main objective of the present study is to investigate if individuals with amnestic mild cognitive impairment show recognition deficits in facial identity. Thirty-seven individuals with amnestic mild cognitive impairment, multiple-domain (15 female; age: 75±8 yrs.) and forty-one healthy volunteers (24 female; age 71±6 yrs...

Describing unfamiliar faces during or immediately after their presentation in a study phase can produce better recognition memory performance compared with a view-only control condition. We treated descriptions as elaborative information that is part of the study context and investigated how context retrieval influences recognition memory. Following general dual-process theories, we hypothesized that recollection would be used to recall descriptions and that description recall would influence recognition decisions, including the level of recognition confidence...

People have difficulties in remembering other-race faces; this so-called other-race effect (ORE) has been frequently observed in long-term recognition memory (LTM). Several theories argue that the ORE in LTM is caused by differences in earlier processing stages, such as encoding of ingroup and outgroup faces. We test this hypothesis by exploring whether the ORE can already be observed in visual working memory (VWM)-an intermediate system located between encoding processes and LTM storage. In four independent experiments, we observed decreased performance for outgroup faces compared to ingroup faces using three different VWM tasks: an adaptive N-back task, a self-ordered pointing task, and a change detection task...

INTRODUCTION: Graft-versus-host disease (GVHD) is caused by a pathologic and destructive response of the organism as a result of the interaction between donor immunocompetent T lymphocytes and the recipient tisular antigens. It's considered the most serious complication of hematopoietic stem cell transplantation, most frequently described after bone marrow transplantation (BMT). The skin is usually the first and most commonly affected organ, in both acute and chronic, with a variable clinical spectrum of presentation...

There is accumulating evidence that youths with antisocial behavior or psychopathic traits show deficits in facial emotion recognition, but little is known about the neural mechanisms underlying these impairments. A number of neuroimaging studies have investigated brain activity during facial emotion processing in youths with Conduct Disorder (CD) and adults with psychopathy, but few of these studies tested for group differences in effective connectivity - i.e., changes in connectivity during emotion processing...

When viewing unfamiliar faces, photographs of the same person often are perceived as belonging to different people and photographs of different people as belonging to the same person. Identity matching of unfamiliar faces is especially challenging when the photographs are of a person whose ethnicity differs from that of the observer. In contrast, matching is trivial when viewing familiar faces, regardless of race. Viewing multiple images of an own-race target identity improves accuracy on a line-up task when the target is known to be present (Dowsett et al...

Using a composite-face paradigm, we examined the holistic processing induced by Asian faces, Caucasian faces, and monkey faces with human Asian participants in two experiments. In Experiment 1, participants were asked to judge whether the upper halves of two faces successively presented were the same or different. A composite-face effect was found for Asian faces and Caucasian faces, but not for monkey faces. In Experiment 2, participants were asked to judge whether the lower halves of the two faces successively presented were the same or different...

The spatial confinement of conjugated phenyl rotators is a compulsory requirement for the fluorescence enhancement of aggregation induced emission (AIE) molecules. This work reports a novel spatially confined AIE material by restricting several tetraphenylethylene (TPE) molecules around the primary face of β-cyclodextrin (CD) via a Cu(I) catalytic 1,3-dipolar cycloaddition reaction (click chemistry). The spatial confinement effect was found to significantly enhance the fluorescence emission when compared with a single TPE modified CD...

Background: The demand for health services in developing countries often outweighs provision. This article describes the present condition of physiotherapy in Bangladesh. Physiotherapy is not recognized as a profession by the government. There is no single registration and regulation body. The health-related and economic benefits of physiotherapy are not felt by the majority of Bangladeshi citizens. Areas covered: The burden of disease is changing, and Bangladesh needs a profession that specializes in physical rehabilitation to face these challenges...

BACKGROUND: The developmental trajectory of psychopathy seemingly begins early in life and includes the presence of callous-unemotional (CU) traits (e.g., perturbed socioaffective reactivity and empathy, callousness) in youths with conduct disorder (CD). Whereas oxytocin receptor gene methylation (OXTRMeth ) and its downstream neuromodulatory effects are deemed relevant to CU traits, nothing is known of how OXTRMeth interacts with CU traits to impact socioaffective brain systems in youngsters with CD...

Dysfunction in the understanding of social signals has been reported in persons with epilepsy, which may partially explain lower levels of life satisfaction in this patient population. Extensive assessment is necessary, particularly when the mesial temporal lobe, responsible for emotion processing, is affected. The authors examined multiple levels of social perception in patients with mesial temporal lobe epilepsy (MTLE), including judgments of point-light motion displays of human communicative interactions (Communicative Interactions Database-5 Alternative Forced Choice format) and theory-of-mind processes evaluated using geometric shapes (Frith-Happé animations [FHA])...

OBJECTIVE: Previous research has consistently shown that the ability to recognize emotions from facial expressions is impaired in Huntington's disease (HD). The aim of this study was to examine whether people with the gene expansion for HD visually scan the most emotionally informative features of human faces less than unaffected individuals, and whether altered visual scanning predicts emotion recognition in HD beyond general disease-related decline. METHOD: We recorded eye movements of 25 participants either in the late premanifest or early stage of HD and 25 age-matched healthy control participants during a face-viewing task...

People form impressions of others from multiple sources of information. Facial appearance is one such source and judgments based on facial appearance are made after minimal exposure to faces. A more reliable source of information is affective person learning based on others' past actions. Here we investigated whether the effects of such appearance-independent learning on face evaluation emerge after rapid face exposure, a response deadline procedure, and a lack of explicit recognition of the faces. In three experiments, participants learned to associate novel faces with negative and positive behaviors, and then evaluated the faces presented on their own, without the behaviors...

AIM: Seeing a speaker's face facilitates speech recognition, particularly under noisy conditions. Evidence for how it might affect comprehension of the content of the speech is more sparse. We investigated how children's listening comprehension is affected by multi-talker babble noise, with or without presentation of a digitally animated virtual speaker, and whether successful comprehension is related to performance on a test of executive functioning. MATERIALS AND METHODS: We performed a mixed-design experiment with 55 (34 female) participants (8- to 9-year-olds), recruited from Swedish elementary schools...
