The following hypotheses were experimentally investigated 1 A distinct semantic-memory ability exists for each of the six product categories of the Structure-of-Intellect SI model 2 Six semantic Divergent-Production DP abilities can be identified in a senior-high-school population and 3 The six memory abilities are unrelated to semantic abilities in the other operation categories of the SI model. A sample of 175 11th-grade students was tested with a battery of 50 intellectual-aptitude tests. Of these tests, 28 were newly written and were designed for aspects of semantic memory 14 were measures of divergent production and 8 were marker tests for factors in other operation categories. All factorial hypotheses were found to be tenable. The newly demonstrated semantic-memory abilities are memory for isolated items of information memory for class ideas memory for meaningful connections between meaningful items of information memory for the structure or order of information memory for redefinitions and other changes in information and memory for arbitrary connections between meaningful items of information.
