Goal: To examine the potential relationship between psychophysiological indices of attentional bias to environmental stimuli (including alcohol-related images) as measured using traditional eye tracking characteristics (e.g., dwell time, point of initial fixation) vs. basic oculomotor plant metrics (e.g., in response to moving points of light). To examine the predictive capacity of eye-tracking measures, obtained via traditional attentional bias measures (e.g., dwell time and initial point of fixation to alcohol-related images) and oculomotor plant metrics (e.g., in response to moving points of light), for development of binge drinking first years of the college experience.

Motivation: College binge drinking is an issue of major concern in our society. Substance users’ cognitive processing of addiction-related stimuli (such as pictures of alcoholic beverages) is a critical component of craving, and ultimately, the use of addictive substances (such as alcohol). Pre-existing risk factors and exposure to alcohol could influence students’ perceptions of and attention to alcohol-related stimuli, an important determinant in students’ decisions to engage in risking drinking behaviors. Many studies have verified the link between attentional biases to addiction-related stimuli and the development and maintenance of addiction, as well as in relapse after periods of abstinence from an addictive substance. However eye-tracking studies of attentional bias to alcohol-related images have focused on simplistic eye-tracking metrics such as point of initial fixation (which component of the image is viewed first) and dwell time (how much time is spent looking at a particular aspect of the image), but basic physiological responses of the oculomotor system to control stimuli such as moving points of light was not investigated.
