What is Guilford Theory of Intelligence B.Ed Notes

Guilford Theory

Joy Paul Guilford was an American psychologist born on 7 March 1987, in Marquette, Nebraska, U.S. Guilford came up with his theory of intelligence in 1956. He was interested in learning the unevenness of abilities in different domains of children. For him, Intelligence was based not only on one attribute but on various intellectual abilities.

Guilford’s Structure of Intellect Theory

Guilford’s Structure of Intellect (SOI) Model is a theory of multiple intelligences. According to Guilford, Intelligence is a mixture of multiple abilities rather than one attribute. SI theory comprises up to 150 different components of intelligence arranged along three dimensions, which are operation, content, and products.

Operations dimension

There are six operations:


It is the ability to understand, comprehend, discover, and become aware of the information gathered.

Memory recording

It is the ability to memorize information.

Memory retention

It is the ability to recollect information.


It is the ability to know if the information is accurate and valid or not.

Divergent production

It is the ability to come up with several solutions to a problem.

Convergent production

It is the ability to end up with a single solution to a problem.

Products dimension

There are six products:


It is a single item of information.


It is a set of items sharing common attributes.


It is the items linked as opposites or in associations, sequences, or analogies.


It is multiple items interrelated to compromise structures or networks.


Change’s perspectives, conversions, or mutations to knowledge.


Predictions, inferences, consequences, or anticipations of knowledge.

Content dimension

It is the visual information perceived through the eyes.


Information perceived by the ear


Information is perceived as symbols or signs that mean something else.


Information is perceived verbally in words or sentences. It may be in written form or orally.
