Lee Hogarth, PhD

Dr. Hogarth is an experimental psychologist studying learning mechanisms underpinning individual vulnerability to addictive behaviour. His work has revealed that vulnerability to dependence in humans is not conferred by attentional bias, cue-reactivity or propensity to habit or compulsion, but by excessive valuation of the drug relative to alternative competing rewards driving up goal-directed drug choice, plus sensitivity to negative affect acting as a motivational state to further augment drug valuation and goal-directed drug choice. Hogarth advocates socioeconomic population level interventions for drug users to facilitate access to competing alternative sources of reward. He has published multiple articles in peer reviewed journals.

Matt Field, D. Phil.

Dr. Field is a Professor in the Department of Psychology, University of Sheffield. He conducts research into the psychological mechanisms that underlie alcohol problems and other addictions, and is particularly interested in the roles of decision-making and impulse control in addiction, recovery, and behaviour change more broadly. He has published multiple articles in peer reviewed journals.
