| Abstract: | Two tests were made of inferences about how learning strategies affect recall accuracy, and how peculiarities of strategy might account for mentally retardeds' memory deficiencies. Learning strategy was defined as the pattern of pauses generated by S as he paced himself through serial lists of letters. When given freedom to proceed as they wished, normally intelligent Ss paused increasingly the deeper they went into the list. Retarded Ss did not. It was concluded that the normals' active strategies contribute to their high primacy, while the retardeds' lack of distinctive pauses accounts for their low primacy. In the second test, the strategies were reversed. The normals were forced to abandon rehearsal; the retardeds were forced to rehearse. This resulted in greatly enhanced primacy for the retardeds, and greatly decreased primacy for the normals. In addition to showing how spontaneous strategies and forced strategies can directly influence recall accuracy, these findings suggest a reasonably simple means of mitigating short-term memory deficiencies. |
