J.P. Guilford proposed the Structure of Intellect (SOI) model to describe 180 different types of intellectual abilities. The SOI model categorizes abilities into three dimensions: operations (6 types of thinking processes), content (5 types of information), and products (6 types of outcomes). Each combination of one operation, one content, and one product defines a specific intellectual ability. The model suggests intelligence involves distinct skills that can be improved through training. It also implies curriculum should incorporate different combinations of operations, content, and products to develop students' intellects based on their individual differences.

2. • It is the result of Factor analytic research conducted by
Guilford and his associates in the Psychological Laboratory,
at the University of Southern California, USA.
• According to him an individuals performance on an
intelligence test can be traced back to underlying mental
abilities or factors of intelligence which are 180 in number
and can be organized under the following three
dimensions:
Operations: act of thinking/ Psychological Process
Content: content/ material i.e. nature of
information on which one works
 Products: Outcome of the working of Operations on
Content

• Visual: Information perceived through seeing
• Auditory: Information perceived through hearing
• Symbolic: Symbols and signs that have no meaning in themselves
• Semantic: Words/ sentences – oral/ written or in one’s mind
• Behavioural: Acts of individual/ individuals

• Units: Single items of knowledge- words, shapes, facial expression
• Classes: Organizing units into groups based on shared attributes
• Relations: Linking units either as opposites, associates, sequences or
analogues
• Systems: Multiple relation between units to create a network/
structures
• Transformations: Changes, perspectives, mutations to knowledge
• Implications: Predictions, inferences, consequences

4. SCHEMATIC REPRESENTATION OF SOI MODEL

5. EDUCATIONAL IMPLICATIONS OF THE SOI MODEL
i. Intellect is a matter of skills and hence can be
improvised through training.
ii. Must consider individual differences among
students.
iii. Ability to judge people’s behaviour .
iv. Curriculum should be such that a combination of
operations, content and product is made for the
development of intellect.
