Research summary

My primary research interest and the focus of my PhD is cognitive control in eating behaviours. Through a series of behavioural studies, I currently examine the cognitive and affective components underlying food preferences and choices between healthy and unhealthy foods. In another pre-registered study, a novel inhibitory control training (ICT) paradigm was investigated as an intervention for changing food evaluations. As part of the GW4 Undergraduate Psychology Consortium 2017/2018, a behavioural study was conducted to examine the effects of ICT on approach-avoidance tendencies in a large sample recruited from Cardiff University, University of Exeter and University of Bath campuses. I am an advocate of open science practices and all behavioural projects to date have been pre-registered on the Open Science Framework.
