Neural and Cognitive Studies of Reward Sensitivity and Its Influence on Addiction-Related Behaviour

Grant number: DP1092852 | Funding period: 2010 - 2013

Completed

Abstract

The proposed research aims to contribute to current scientific thinking on the influence of reward sensitivity on cognitive performance. Cognitive neuroscience research on this relationship is of major scientific interest because heightened reward sensitivity is a significant predictor of risk for a number of Australia's major social and economic problems. The findings of this project will contribute to the debate about how to manage such problems.
