Some Changes in the Structure-of-Intellect Model

This paper serves to update the structure-of-intellect (SOI) model. In addition to a previously indicated separation of the figural element of the content facet of the SOI model into visual and auditory components, the memory element within the operations facet has been differentiated into memory recording and memory retention. Research supporting these changes is cited. Thus the revised SOI model now contains five content properties termed visual, auditory, symbolic, semantic, and behavioral; six operations entitled cognition, memory recording, memory retention, divergent production, convergent production, and evaluation; and the same six products as formerly, named units, classes, relations, systems, transformations, and implications.
