Dove e quando

For decades, social psychology, along with cognitive sciences, has described social interaction, providing theories and models for understanding how humans interact in groups. In Computer Science, more precisely in the field of Social Signal Processing, automated group analysis grounds on such theories to propose tools for understanding and analysing human social behavior. In this seminar, we will illustrate our cognitive-based approach to group analysis of cohesion, “a dynamic process that is reflected in the tendency for a group to stick together and remain united in the pursuit of its instrumental objectives and/or for the satisfaction of member affective needs”. We will start with an overview of main socio-psychological theories on group behavior. After this we will focus on the must-do step before analyzing social interaction: segmenting the material. We will show how the spontaneous capability of human mind to simplify reality by chunking it into smaller units can be leveraged to segment video-recorded social interaction for further annotation. After this, we will move on to a framework exploiting non-verbal behavior for the automated analysis of group cohesion, drawn from cognitive theories on social interaction and inspired by methodologies proposed in the field of social signal processing.
