Applying an elaborate and novel experimental paradigmwe collected non-verbal responses to social inclusion and exclusion. A judgement experiment revealed that it was possible to determine whether a person was included or excluded, based solely on non-verbal, behavioral cues, especially if the person was male. A detailed coding using the ECSI scale suggests that included speakers displayed more ...

A doi:10.1016/j.jesp.2008.03.002 E-mail address: [email protected] Although a great deal is now known about how people mentally represent individuals and groups, less attention has been paid to the question of how interpersonal relationships are represented in memory. Drawing on principles of categorization, this paper reports an investi...

This paper introduces Exclusion Logic a modal logic based on hierarchical finite-state machines. We show how Exclusion Logic can be used as a deontic logic to model social practices. We describe a computer implementation of Exclusion Logic in a multi-agent simulation, and explain how it efficiently resolves conflicts between incompatible norms.

This paper investigates factors likely to increase a person’s risk of social exclusion, drawing on survey data specifically framed for this purpose. We use a generalised ordered logit model that accounts for observed and unobserved heterogeneity and derive the marginal effects for each influencing attribute. We find that people are less likely to be at risk of social exclusion if they have regu...

This study examines the evolution of social networks within groups of six subjects playing a prisoners dilemma game. In each round subjects cannot discriminate in their action choice but can exclude others from their social environment. Four treatments are considered, varying the cost of exclusion and the information flow through the network. Observed cooperation levels strongly depend on the t...

Because the belonging need is fundamental, an exclusion experience thwarts this need and causes cognitive, behavioral, and affective consequences for human functioning. This paper aims to integrate the enumerated effects of social exclusion in a real-world setting. Also, as the boundary between the real world and cyberspace is blurred, it became crucial to understand the dynamics of social rela...

Stigma research suggests that exclusion of peers with mental health problems is acceptable, however, no research has explored young people's beliefs about the fairness of exclusion. Group interviews with 148 adolescents explored judgements about the fairness of excluding peers with ADHD or depression from dyads and groups. Young people evaluated exclusion of peers with ADHD or depression from d...

Social exclusion is known to cause alterations in neural activity and perceptions of social distress. However, previous research is largely limited to examining social interactions as a unitary phenomenon without investigating adjustments in neural and attentional processes that occur during social interactions. To address this limitation, we examined neural activity on a trial-by-trial basis d...

Social ties are crucial for humans. Disruption of ties through social exclusion has a marked effect on our thoughts and feelings; however, such effects can be tempered by broader social network resources. Here, we use fMRI data acquired from 80 male adolescents to investigate how social exclusion modulates functional connectivity within and across brain networks involved in social pain and unde...
