The Composition of Episodic Memory.
Underwood, Benton J.; And Others
This study examined the interrelationships among a number of episodic memory tasks and among various attributes of memory. A sample of 200 college students was tested for ten sessions; 28 different measures of episodic memory were obtained. In addition, five measures of semantic memory were available. Results indicated that episodic and semantic memory were generally unrelated. Among the measures of episodic learning, clustering was found to be unrelated to performance on other tasks. This was also true for a double-function, verbal-discrimination task and for a task designed specifically to measure susceptibility to interference. Twenty-two of the measures were included in a factor analysis from which five factors emerged. One factor was tied to free-recall tasks, another to paired-associate and serial tasks. Memory span constituted a third factor, a fourth factor involved involved verbal-discrimination lists, and a fifth was constituted by frequency assimilation and classical recognition. Reasons for the failure to form factors not tied to the type of task are discussed. (Author/AA)
