Overview

I am part of the Pheasant Ecology and Cognition (PEC) group. The social environment is considered key in shaping cognitive abilities and my research focuses on the causes and consequences of individual variation in cognitive performances in relation to the social environment. I am particularly interested in the relationship between learning performances with aggression and social rank, as well as how learning and inhibitory control abilities influence associative relationships. I investigate cognitive performances of young and adult pheasants in captivity in relation to their social relationships, as well as explore how these performances may predict an individual’s social relationships in the wild.
