摘要: A guessing task was performed in three conditions of feedback sequence. One sequence random; the other sequences were nonrandom. Each subject made 300 responses per session for four sessions. The frequency distribution differences between response/feedback immediately preceding trial and current response analyzed pooled data. results suggest that there are two processes operating this task: a static process dynamic process. This model has advantages. First, it can explain sequential dependencies present study Ward Lockhead’s (1971) Study 3. Second, each proposed here theoretical foundation: is based on subject’s tendency to generate random with many alternatives; modified version learning signal detection (Dorfman, Saslow, & Simpson, 1975).
