In a serial recall task, the "Hebb repetition effect" occurs when recall performance improves for a sequence repeated throughout the experimental session. This phenomenon has been replicated many times. Nevertheless, such cumulative learning seldom leads to perfect recall of the whole sequence, and errors persist. Here the authors report…

Knowledge of the importance of mediating processes for sustaining performance, and of self-organizing abilities for learning to perform a given task, served as the basis for a method (called TASKTEACH) of using a time-sharing digital computer to assist learning of prescriptively-guided or problem-solving serial-action tasks. The students involved…
