Using Guilford's model, the text reviews the structure of the intellect (SOI) and its operations, contents, and products. Those operations and components are further described, including the factors of cognition, memory, evaluation, convergent-production, and divergent-production. For each factor, the figural, symbolic, and semantic dimensions are defined; for cognition, the behavioral dimension is also treated. In addition, for each factor cell, the description is related to psychometric materials and curriculum practices are suggested for the training of that ability. The interpretation of the SOI is explained, with an information-processing model, a proposed schematic for prescriptions in educational psychology, and a mapping procedure for assigning test items to the SOI and illustrative items provided and the SOI and individual tests of intelligence and validation explained. Also explained is the use of templates for translating the results of the Stanford Binet LM, WISC, and WPPSI. Automated programing based on SOI profiles is discussed, with consideration given to common abilities in the Binet and WISC; SOI profiles for clinical types are described, with attention paid to individual profiles based on SOI analyses and steps towards curriculum planning.
