Abstract

The problems discussed in this paper arose during a search for an experimental design that would yield reliable measures of associative interference for the individual subject. Such measures are needed as part of an extensive research project concerned with individual susceptibility to interference in verbal and psychomotor performance. Interference effects are commonly studied in the laboratory under conditions that provide for original learning (OL) of some task to a given criterion, interpolated learning (IL) of a different task to a given criterion, and the subsequent relearning (RL) or recall of the original task. Two measures of interference are sought when this design is employed: (1) the retardation in the learning of the interpolated task resulting from the previous learning of the original task (associative inhibition), and (2) the decrement in the recall of the original task arising from the learning of the interpolated task (retroactive inhibition). A control condition is included to reveal the effects of rest periods (passage of time) inserted between the learning of the original task and its later recall.
