Research summary

I'm researching the psychology of food choice in  naturalistic settings, with a particular focus on how these settings can be  architected to promote healthier choices.

Part of this research involves a focused exploration of the Welsh Healthy Vending directive, which instructs hospitals in Wales to restrict their vending  machines to stock only healthy options and display only health-promoting labels  and signage.  We will measure the effects of the directive on the  profitability of vending, and explore whether manipulating product prices,  promotional material, and the locations of vending machines can push consumers towards healthier choices.

Other avenues of interest to us include the consequences of imposing healthy  choices on individuals, and the circumstances in which health-promoting labels  and signage do or do not influence choices.
