PhD Student

Sergio is a PhD student in the Department of Psychology. He graduated in Psychology in 2013, and obtained his Masters Degree in Animal Behaviour in 2014. His PhD involves the systematic observation and study of the chimpanzee group at Chester Zoo, with the objectives of studying the social network of the group and its relationship with personality and laterality of hand preference.

Research

Sergio’s research aims to explore the social network of a captive group of chimpanzees and its relationship with personality and laterality of hand preference. Social Network Theory has been widely used in social sciences for decades, but it has only recently been applied to the study of non-human animal behaviour. SNT allows the use of quantitative metrics that offer valuable information about why social structure matters and how the relative position of a given individual in said structure can influence its behaviour. These metrics can provide data about how social groups are formed and persist, and how different individual behaviours affect the group as a whole. Using SNT, Sergio’s PhD will investigate the role of hand preference in cooperation and competition within a group as well as how personality affects the position of individuals within a group.
