introduction phenylketonuria (pku) is a congenital metabolic disorder of phenylalanine, if which, the diet is not to be followed exactly, it can lead to progressive mental retardation. the purpose of this study was to investigate the effect of face to face and non-face to face trainings by parental on controlling serum phenylalanine levels in the children with phenylketonuria. materials and met...

We use Goffman’s characterization of "front" and "backstage" interaction practices to analyze how the use of instant messaging in both face-to-face and technology-mediated meetings alters the spatial, temporal, and social configurations of meetings. In an interview study of workers in two organizations, we found that workers used instant messaging during face-to-face meetings and telephone co...

We predicted that able-bodied individuals and White Americans would have a difficult time saying no to persuasive appeals offered by disabled individuals and Black Americans, due to their desire to make such interactions proceed smoothly. In two experiments, we show that members of stigmatized groups have a peculiar kind of persuasive ‘‘power’’ in face-to-face interactions with non-stigmatized ...

Knowledge of how groups of people interact is important in many disciplines, e.g. organizational behavior, social network analysis, knowledge management and ubiquitous computing. Existing studies of social network interactions have either been restricted to online communities, where unambiguous measurements about how people interact can be obtained, or have been forced to rely on questionnaires...

In this paper we describe patterns of spatial co-ordination that, we propose, are a distinctive characteristic of multi-person face-to-face interactions. The data come from a task in which participants describe some simple, non-spatial, computer code in an instructor / learner scenario. Three participants take part; 2 instructors and 1 learner. Using excerpts from these interactions we show tha...

Media naturalness theory and social information processing theory make competing predictions regarding the effectiveness of different modes of communication at creating and maintaining emotionally intense social relationships. We explored how the duration of interaction and the form of laughter influenced happiness in communication modes with different levels of media naturalness. Forty-one par...

Humans and other primates spend much of their time engaged in social interactions where a crucial ability is to decode face expressions and act accordingly. This rapid reversal learning has been proposed to be important in the relative evolutionary success of primates. Here we provide the first neuroimaging evidence that the ability to change behaviour based on face expression in a model of soc...

In this paper, we describe two series of experiments that examine audiovisual face-to-face interaction between naive human viewers and either a human interlocutor or a virtual conversational agent. The main objective is to analyze the interplay between speech activity and mutual gaze patterns during mediated face-to-face interactions. We first quantify the impact of deictic gaze patterns of our...

Nonverbal behavior expresses many of the dynamics underlying face-to-face social interactions, implicitly revealing one's attitudes, emotions, and social motives. Although research has often described nonverbal behavior as approach versus avoidant (i.e., through the study of proxemics), psychological responses to many social contexts are a mix of these two. Fairness violations are an ideal exam...
