Effects of Alcohol on Persistent Effort and Deductive Thinking During the Preparation Phase of the Creative Process

According to the four stage model of creativity (Wallas, 1926/1970) the first stage is a phase of preparation, which requires a persistent intellectual effort over time and ability to reason deductively. The present study explored whether alcohol intoxication would impair these two abilities. 42 men and women were randomly assigned to either an Alcohol, a Placebo, or a Control group. After drinking subjects completed two tests measuring persistent effort and deductive reasoning. Results indicated that the Alcohol and Placebo groups were impaired with respect to persistent effort and that the Alcohol group also was impaired with respect to deductive reasoning. Consequences for the creative production under alcohol intoxication were discussed.
