The effects of two training procedures on learning and performance are compared. Performers select a response alternative for each stimulus on Trial I and receive feedback in terms of "Right" or "Wrong". Observers receive the same information by listening to the experimenter. Experiment I tests the hypothesis that performers and observers are using a different learning strategy when there are only two response alternatives available for each stimulus on Trial I. A recognition procedure was used on Trial z ; each stimulus was followed by four alternatives, two of them being the same as presented on Trial I , Subjects have to recognize the two "old" alternatives. Performers are always better at recognizing the chosen alternative, whereas observers are better at recognizing the correct alternative. Experiment I1 extends the comparison between performers and observers to a task with four response alternatives on Trial I. There are no longer differences in performance between the two training procedures.
