BIOGRAPHY

His original undergraduate degree was in genetics from the University of Sheffield, and he obtained a PhD in molecular biology from Queens College, Cambridge in 1990. He worked for a number of years at the Ministry of Agriculture, Fisheries and Food (now DEFR) as a science advisor and administrator; during this time he studied for a BSc in Psychology at Birkbeck College, London. He then worked as a research assistant – first at London Guildhall University and then at the University of Birmingham. While at Birmingham he started a PhD in cognitive development that he completed in 2005. He lectured at London Metropolitan University before joining the University of Essex in 2008.

RESEARCH OVERVIEW

I am interested in how we develop those cognitive abilities that make us human and different from other animals. How is it that we are able to understand the way that the world works; and to control our behaviour, to achieve our goals within this world?

I began with an interest in executive functions (the higher cognitive abilities necessary to engage in complex, flexible, goal-oriented behaviour).  Research has focused on the early development of inhibitory control and working memory – as these basic executive functions may underpin the development of more complex abilities in later childhood and adolescence.  In particular this work has questioned what makes some behaviours prepotent (so that they are sometimes triggered inappropriately – creating the need for inhibitory control).

Investigating what makes actions prepotent led to an interest in imitation (a ‘notoriously prepotent behaviour’) and in the habitual actions made when using tools.  This in turn has led to two further research questions.  1) How does children’s knowledge of tools develop, and so enable them to operate in artefact-dense cultures?  And, 2) What do children and adults think about when they see others act with tools?
