Analysis of Cine-Psychometric Visual Memory Data by the Tucker Generalized Learning Curve Method: Final Report.
Reid, J. C.; Seibert, Warren F.
The analysis of previously obtained data concerning short-term visual memory and cognition by a method suggested by Tucker is proposed. Although interesting individual differences undoubtedly exist in people's ability and capacity to process short-term visual information, studies have not generally examined these differences. In fact, conventional analyses have used group means which destroy the investigation of individual differences. Previous research by the authors indicates substantial and reliable changes in the abilities a group of subjects uses to process information as the stimulus itself subtly changes. These changes that an individual manifests have, however, been obscured until now. The proposed method by Tucker simultaneously analyzes the differences among subjects and describes the complexity of the stimulus. Thus the behavior of a single individual to a visual stimulus can be summarized and analyzed in light of other abilities he may possess. Tucker's method can estimate practice and fatigue effects on a task. Finally, the experience gained herein with the Tucker method should prove useful, in that it could be an alternative way of analyzing individual differences other than the regression approach.
