IntroductionLittle is known about the outcomes of subjects with a history of severe acute malnutrition (SAM). We therefore sought to explore the long-term effects of SAM during childhood on human capital in adulthood in terms of education, cognition, self-esteem and health-related disabilities in daily living.MethodologyWe traced 524 adults (median age of 22) in the eastern Democratic Republic of the Congo, who were treated for SAM during ...

Transition from acute whiplash injury to either recovery or chronicity and the development of chronic whiplash-associated disorders (WAD) remains a challenging issue for researchers and clinicians. The roles of social support and personality traits in long-term functioning following whiplash have not been studied concomitantly. The present study aimed to examine whether social support and personality traits are related to long-term functioning ...

Background: Humans can easily grasp the affective meaning of touch when observing social interactions. Several neural systems support this ability, including the theory of mind (ToM) network and the somatosensory system linked to embodied resonance, but it is unclear how these systems are affected in autism spectrum disorder (ASD). Individuals with ASD exhibit impairments in the use of nonverbal communication such as social and reciprocal touch. ...

Monitoring of one's own and other's performance during social interactions is crucial to efficiently adapt our behavior and to optimize task performance. In the present study we investigated to what extent social factors can modulate behavioral adjustments in performance. For this purpose, participants executed a flanker task and alternated either with a computer program or with a human partner in cooperative and competitive contexts. ...

Background Intranasal administration of the prosocial neuropeptide oxytocin is increasingly explored as a potential treatment for targeting the core characteristics of autism spectrum disorder (ASD). However, long-term follow-up studies, evaluating the possibility of long-lasting retention effects are currently lacking. Methods Using a double-blind, randomized, placebo-controlled, parallel design, this pilot clinical trial explored the ...

Background: Intranasal administration of the "prosocial" neuropeptide oxytocin is increasingly explored as a potential treatment for targeting the core characteristics of autism spectrum disorder (ASD). However, long-term follow-up studies, evaluating the possibility of long-lasting retention effects, are currently lacking. Methods: Using a double-blind, randomized, placebo-controlled, parallel design, this pilot clinical trial explored the ...

Social anxiety disorder (SAD) is characterised by fear of social or performance situations where the individual is exposed to unfamiliar people or to possible scrutiny by others. The literature on dopamine ligands and dopamine genotypes in SAD is however inconsistent. In this study we measured the effects of SSRI pharmacotherapy on dopamine transporter (DAT) binding in patients with SAD, also addressing variability in DAT genotype. Adult ...

Outcome monitoring is crucial for subsequent adjustments in behavior and is associated with a specific electrophysiological response, the feedback-related negativity (FRN). Besides feedback generated by one's own action, the performance of others may also be relevant for oneself, and the observation of outcomes for others' actions elicits an observer FRN (oFRN). To test how these components are influenced by social setting and predictive value ...

In science findings which cannot be extrapolated to other settings are of little value. Recruitment methods vary widely across chronic whiplash studies, but it remains unclear whether this generates recruitment bias. The present study aimed to examine whether the recruitment method accounts for differences in health status, social support, and personality traits in patients with chronic whiplash-associated disorders (WAD). Two different ...

The question of how we can voluntarily control our behaviour dates back to the beginnings of scientific psychology. Currently, there are two empirical research disciplines tackling human volition: cognitive neuroscience and social psychology. To date, there is little interaction between the two disciplines in terms of the investigation of human volition. The aim of the current article is to highlight recent brain imaging work on human volition ...
