The proposed research aims where to investigate the role of context on approach tendencies and attentional biases and relate this to actual drinking behavior in moderate and heavy drinkers. The study consists of two parts. First, approach tendencies and attentional biases towards alcohol related versus neutral contexts will be measured by two computerized tasks that has been used in previous experiments. These tasks will be an approach/avoidance task (i.e. stimulus-response compatibility task ) and a dot probe task . Second, influences of specific contexts on actual drinking behavior are measured by repeated assessments while participants attend drinking events. Repeated assessments consist of real-time questionnaires that will be administered by mobile phone software at nights when participants are drinking for four week s. Participants (N =200) will be students, recruited at the Radboud University and the HAN (Hogeschool van Arnhem en Nijmegen) and will first be screened on drinking behaviour.
