A consistent attentional bias for drug-related material in active cocaine users across word and picture versions of the emotional Stroop task

Abstract

Evidence from a number of drug-abuse populations suggests that an attentional bias for drug-related stimuli can be identified in chronic users. Such an effect has yet to be reliably demonstrated in cocaine users, despite mounting evidence of the salience and reinforcing properties of cocaine-related cues. The aim of the current study was to administer word (modeled on the versions shown to successfully identify attentional biases in alcohol abusers) and picture versions of the emotional Stroop tasks to gauge the reliability of cocaine-specific attentional biases across stimuli domains. A comparison of active cocaine users (n = 23), and their age and education matched controls revealed a sign..
