A diffusion model decomposition of the effects of alcohol on perceptual decision making

Key Points

The research investigates how alcohol affects the speed of decision-making in perceptual tasks.
Conducted a simple perceptual discrimination task
Administered moderate doses of alcohol to participants
Measured changes in information processing and decision components
Alcohol decreased the rate of information processing
Moderate alcohol negatively affected the non-decision component
Response caution remained largely unchanged

Abstract

In a simple perceptual discrimination task, even a moderate dose of alcohol decreased the rate of information processing and negatively affected the non-decision component. However, alcohol consumption left response caution largely intact.
