Effect of cues associated with an alcoholic beverage on executive function

Area of Science:

• Neuroscience
• Psychology
• Behavioral Science

Background:

• Alcohol consumption can impair cognitive functions such as inhibition, working memory, and attention.
• Environmental cues associated with alcohol may trigger conditioned responses.
• Understanding these conditioned responses is crucial for managing alcohol's effects.

Purpose of the Study:

• To determine if alcohol-associated drink cues elicit conditioned compensatory responses.
• To investigate if these responses can mitigate alcohol's negative effects on cognition and alertness.

Main Methods:

• A between-subjects study with three groups: alcohol-associated lager drink, non-associated fruit squash, and non-associated apple schnapps.
• Participants received a standardized dose of alcohol (0.65 g/kg for men, 0.57 g/kg for women).
• Cognitive functions (inhibition, working memory, set-shifting) and alertness were assessed using the CANTABeclipse battery before and after consumption.

Main Results:

• The lager group exhibited less disinhibition and a smaller reduction in alertness compared to the other groups.
• The lager group demonstrated faster responses in a set-shifting task.
• No significant differences in subjective drink evaluations were found across groups.

Conclusions:

• Cues associated with alcohol, such as lager's taste and smell, may elicit compensatory responses.
• These conditioned responses appear to counteract alcohol's cognitive effects and impact on alertness.
• Findings suggest a potential mechanism for how learned associations influence alcohol's physiological and cognitive outcomes.
