Abstract

This poster investigates the role of sleepiness and dopamine function (measured by spontaneous eye blink rate; sEBR), in impulsive action toward food stimuli. Analysis of Go/NoGo performance suggests that participants were more impulsive toward food stimuli compared to non-food stimuli, although there was no significant difference between high-calorie and low-calorie foods. A curvilinear relationship was found between sleepiness and high calorie NoGo accuracy. sEBR did not correlate to either sleepiness or Go/NoGo performance.
