简要总结
This preregistration documents an experiment examining the effects of acute stress and social context on alcohol-related decision-making. The study uses a 2x2 factorial design (stress vs. control × social vs. alone) with dyadic recruitment.
详细描述
Behavioral data:
Our first set of hypotheses tests whether the decision is influenced by stress and social context:
H1a: Stress affects the decision between alcoholic and non-alcoholic drinks, so that participants in the stress conditions choose alcoholic over non-alcoholic drinks more often compared to participants in the no stress conditions.
H1b: Social context affects the decision between alcoholic and non-alcoholic drinks, so that participants in the social conditions choose alcoholic over non-alcoholic drinks more often compared to participants in the alone conditions.
H1c: We test two competing predictions:
