The role of sex and androgen receptors (ARs) for social preference and social memory is rather unknown. In this study of mice we compared males, females and males lacking ARs specifically in the nervous system, AR(NesDel), with respect to social preference, assessed with the three-chambered apparatus test, and social recognition, assessed with the social discrimination procedure. In the social ...

We describe several forms of machine learning that are being applied to social interaction in Human-Robot Interaction (HRI), using a robot bartender as our scenario. We first present a data-driven approach to social state recognition based on supervised learning. We then describe an approach to social interaction management based on reinforcement learning, using a data-driven simulation of mult...

It has been hypothesized that social developmental disorders (SDD) like autism, Asperger's disorder and the social-emotional processing disorder may be associated with prosopagnosic-like deficits in face recognition. We studied the ability to recognize famous faces in 24 adults with a variety of SDD diagnoses. We also measured their ability to discriminate changes in internal facial configurati...

The cross-race effect (CRE) describes the finding that same-race faces are recognized more accurately than cross-race faces. According to social-cognitive theories of the CRE, processes of categorization and individuation at encoding account for differential recognition of same- and cross-race faces. Recent face memory research has suggested that similar but distinct categorization and individu...

objectives: the main purpose of the present study is to consider the rate of impression in group mental rehabilitation based on the regulation of self recognition sources on augmentation of self-respect among 14- to 18-year old female prisoners. methods: 30 female social seekers were randomly selected from the whole population, 15 of which were gathered in control group and the rest 15 within e...

We demonstrate a Semantic Web application that organizes social events for friends in the larger San Francisco Bay Area using real data from available web sources. We use a collection of techniques that will be at the heart of the next wave of applications on the web; entity extraction, querying federated databases, efficient spatial reasoning, temporal reasoning, practical RDFS++ reasoning, re...

Social cognition is important in everyday-life social interactions. The social cognitive effects of 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy') and methylphenidate (both used for neuroenhancement and as party drugs) are largely unknown. We investigated the acute effects of MDMA (75 mg), methylphenidate (40 mg) and placebo using the Facial Emotion Recognition Task, Multifaceted Empathy T...

Social recognition is the basis of all social interactions. Here, we show that, in humans, the evolutionarily highly conserved neuropeptide oxytocin, after intranasal administration, specifically improves recognition memory for faces, but not for nonsocial stimuli. With increased oxytocin levels, previously presented faces were more correctly assessed as "known," whereas the ability of recollec...
