• Resumen

  • Difficulties with chronopsychology studies include a masking effect of variables, the combination of different rhythms and variations of strategies. An experiment is conducted to analyze the role of circadian variations of elementary processes in the variations of performance for a complex task. Twenty-four subjects solved anagrams and tried to find the rule of anagram construction, during two sessions, at 10 am and 5 pm. Responses were classified in three groups : (a) discovery of the anagram construction rule (R2 responses) ; (b) resolution of anagram without discovery of rule (Rl responses) ; (c) failure, no resolution of anagram (RO responses). During the second session, R2 performances were better at 10 am than at 5 pm. In contrast, Rl performances were better at 5 pm than at 10 am. Rule application was faster at 10 am than at 5 pm. Results are discussed in terms of variations of short-term memory capacity (Folkard and Monk, 1980). Using chronopsychology to analyze the role of elementary processes in a complex task is discussed.
