J.P. Guilford classified the structure-of-intellect model into ___________.

Operations, Contents and Products

J.P. Guilford proposed the structureof-intellect model which classifies intellectual traits among three dimensions: operations, contents, and products. Operations are what the respondent does. These include cognition, memory recording, memory retention, divergent production, convergent production, and evaluation. Contents refer to the nature of materials or information on which intellectual operations are performed. These include visual, auditory, symbolic (e.g., letters, numbers), semantic (e.g., words) and behavioural (e.g., information about people’s behaviour, attitudes, needs, etc.). Products refer to the form in which information is processed by the respondent. Products are classified into units, classes, relations, systems, transformations, and implications. Since this classification (Guilford, 1988) includes 6´5´6 categories, therefore, the model has 180 cells.
