My research to date has focused on five main areas:1. Goal and implementation intentions as determinants of behaviour change How do people achieve their goals and make changes to their behaviour? The usual answer is that people need to be motivated. However, even medium-to-large changes in people's intentions seem to have only a small-to-medium effect on their behavior. In short, motivation is not enough. As a result, much of my research to date has investigated how the effects of motivation can be boosted by forming specific plans -- known as "implementation intentions" -- that link good opportunities to act with suitable responses to those opportunities. 2. Internet-based interventions for health behaviours The Internet is increasingly used as a medium for the delivery of interventions designed to promote health behavior change. However, reviews of these interventions to date have not systematically identified intervention characteristics and linked these to effectiveness. We conducted a meta-analysis that attested to the importance of using theory to guide intervention development and compared the relative efficacy of a number of behaviour change techniques and modes of delivery. 3. Emotion regulation As part of an ESRC large grant titled "Emotion Regulation in Others and Self" (EROS) we are investigating the efficacy of a number of affect regulation strategies as well as the neurophysiology of emotion regulation. 4. Stereotypes and prejudice We’ve shown that the communication of stereotypical information in non-fictional sources (e.g., newspaper articles) differs from that in fictional sources (e.g., stories). I'm also developing an unobtrusive measure of prejudice based on an advice-taking paradigm used by Mansell and Lam (2006). 5. Public engagement of science We applied an augmented Theory of Planned Behaviour to understand scientists’ decisions to participate in public engagement of science events. Although many scientists agreed that a lack of time and money were an issue, these factors did not influence their intentions to participate. Instead, it was scientists’ attitudes toward public engagement, perceptions of control, and descriptive (not subjective) norms that determined intentions.
