The focus of this report was the degree of independence of memory attributes in determining performance. A demonstration experiment indicated that memory can carry an associative attribute and a frequency attribute simultaneously with little interaction between the two, that is, they were independent in their influence on performance. The discussion centered on attribute control as a function of perceived task demands, on the distinction between attribute composition and attribute utilization, and on certain problems inherent in the analysis of memory and the corresponding problems in theory construction.
