How the success of a group depends on its size and network structure

Winter Mason
Computational Social Scientist

ABSTRACT: In this talk I present two studies on group size and structure and the success of the group. In the first study, we experimentally manipulated the communication network structure of groups of people collectively searching a problem space for an optimal solution, and observed the effects on the groups' success. In the second study, we experimentally manipulated the number of people collaboratively working to extract, classify, geolocate, and validate events in a crisis from reports on social media, and observed the groups' ability to identify and correctly map key events. We find, across these two studies, that the composition of a group can have large effects on task performance, and not always in the ways one would expect.

BIO: I'm interested in things that bridge levels of social science. How do micro-level processes result in macro-level outcomes?

I specialize in social computing, especially crowdsourcing, social psychology, cognitive science, social media, and social network analysis.
