title: Self-assessment of inebriation from external indices.
abstract: OBJECTIVE
  The objective was to study people's judgments, through the use of external indices, of their expected degree of inebriation and to characterize the cognitive processes involved in making these judgments.
  
  
  METHODS
  The participants were 143 adults living in France. In accordance with N. H. Anderson's functional theory of cognition (1982, 1996), their primary task was to read 64 cards depicting drinking situations characterized by three parameters: number of glasses, type of drink, and temporal relation to eating; to associate with each situation a certain degree of personal intoxication; and to indicate this degree of expected intoxication on linear scale anchored by Not at all drunk and Extremely drunk.
  
  
  RESULTS
  Participants were able to judge the general direction and combination of effects. They indicated incorrectly, however, that incremental effects decrease at higher levels of consumption (4 or more glasses) and at higher concentrations of alcohol in a drink. On the other hand, they indicated correctly that eating food decreases the impact of drinking alcohol. Drinkers and nondrinkers used different rules for self-assessment from external indices. IMPICATIONS: The systematic errors in both drinkers' and nondrinkers' use of external clues could, unless corrected, result in their becoming more inebriated than intended.
