Does alcohol automatically capture drinkers' attention? Exploration through an eye-tracking saccadic choice task.

Area of Science:

• Neuroscience
• Psychology
• Addiction Research

Background:

• Theoretical models suggest automatic attentional bias (AB) to alcohol stimuli is a core feature of alcohol use disorder.
• This AB has been observed in binge drinkers, but its automatic nature remains unconfirmed.

Purpose of the Study:

• To investigate the automatic nature of attentional bias (AB) in binge drinkers using an alcohol-related saccadic choice task.
• To determine if alcohol-related stimuli automatically capture attentional resources in binge drinkers, similar to faces.

Main Methods:

• Forty-three binge drinkers and 44 controls completed two saccadic choice tasks: one with faces/vehicles and another with alcohol/non-alcohol stimuli.
• Eye-tracking measured saccadic responses (accuracy, speed, amplitude) to assess attentional capture and disengagement.

Main Results:

• The automatic attraction to faces was replicated in both groups.
• No differences were found in initial saccade accuracy, speed, or amplitude towards alcohol stimuli between binge drinkers and controls.
• Binge drinkers showed a higher proportion of corrective saccades away from non-alcoholic stimuli after initially targeting alcohol, suggesting an alcohol disengagement bias.

Conclusions:

• Alcohol-related attentional bias in binge drinkers is not driven by automatic attention capture.
• The bias appears to involve later, more controlled processing, specifically a difficulty in disengaging attention from alcohol-related stimuli.
