Martha McClintock is a biopsychologist who specializes in social behavior and the regulation of fertility. It is through her pioneering work that menstrual synchrony amongst social groups of females was discovered to be a result of human pheromonal interactions. During McClintock's undergraduate work at Wellesley College, she observed that menstrual synchrony was a common phenomenon between her...

Social groups are fundamental building blocks of human societies. While our social interactions have always been constrained by geography, it has been impossible, due to practical difficulties, to evaluate the nature of this restriction on social group structure. We construct a social network of individuals whose most frequent geographical locations are also known. We also classify the individu...

We are interested in the role that visual (social) identity plays in product adoption. How does the type of people who own and are seen to use a particular product/service influence others' likelihood of purchase? For example, might men be less likely to buy a sporty coupe automobile if they observe lots of women are driving it? Might these cross-group effects be more likely in certain car cate...

UNLABELLED The paper discusses same aspects of psychodynamics and regression of social groups. The aims of the study are: 1. to promote the understanding of group processes which point out the presence of complex phenomena within social group and should help group members and a group leader to function on the higher level of sensitivity, capability and effectiveness; 2. to stimulate the knowled...

This chapter introduces some basic methods to deal with groups of people in surveillance settings. Recently, modeling groups has become a very active trend for video surveillance researchers. Our solution is proper of the recently forged field of social signaling, since it embeds notions of social psychology into computer vision techniques, offering a novel research perspective for the video su...

Homo Economicus has progressed from an atomistic and self-interested individual in standard economics to a socially embedded agent in modern economics who is endowed with a particular social identity or with specific preferences for the latter. While this vision makes the economic agent more realistic, its representation by adding variables in an agent’s utility function poses problems. The dis...

Axelrod’s model describes the dissemination of a set of cultural traits in a society constituted by individual agents. In a social context, nevertheless, individual choices toward a specific attitude are also at the basis of the formation of communities, groups and parties. The membership in a group changes completely the behavior of single agents who start acting according to a social identity...

When making decisions, humans can observe many kinds of information about others' activities, but their effects on performance are not well understood. We investigated social learning strategies using a simple problem-solving task in which participants search a complex space, and each can view and imitate others' solutions. Results showed that participants combined multiple sources of informati...

Status differences are ubiquitous and highly consequential. Yet with regard to human social groups, basic questions persist about how status differences develop. In particular, little is known about the processes by which individuals pursue status in social groups. That is, how do individuals compete and jockey for status with their peers? The current paper reviews recent research that helps fi...

Conversational Agents have been shown to be effective tutors in a wide range of educational domains. However, these agents are often ignored and abused in collaborative learning scenarios involving multiple students. In our work presented here, we design and evaluate interaction strategies motivated from prior research in small group communication. We will discuss how such strategies can be imp...
