In a series of 5 experiments, similar keystroke sequences on a computer keyboard were learned and practiced by human subjects. Each experiment consisted of learning sessions followed by a final test session in which the subjects were required to choose and perform one from offered sets of three. In the test session, most subjects showed either primacy or recency effects, and relatively few showed both. The paper discusses the implications of these results for resurgence effects.
