Factor Analysis of Dichotomous Memory Items from a Designed Experiment.
Hofacker, Charles F.
Recently, confirmatory factor analysis has been extended to the case of dichotomous data (e.g., Muthen, 1978). In this study, confirmatory factor analysis was applied to all-or-none recall data from a designed experiment. In the experiment, subjects read pairs of English nouns and then tried to recall the right hand member of the pair when presented with the left hand member. The retention interval was varied within-subjects. Factor analyses treating the within-subject factor as separate variables failed to confirm a unidimensional view of memory. Instead, a distinction between short- and long-term memory was necessary to account for the data. The proposal of Atkinson and Shiffrin (1968), in which memory is held to consist of two separate storage systems, was supported. (Author)
