Tridimension theory of intelligence is propounded by :

Question

Accepted Answer

The Tridimensional theory of intelligence is propounded by J.P. Guilford, making Option 2 the correct answer. Guilford's theory is also known as the Structure of Intellect (SI) model, which he developed to explain the complexity of human intelligence. According to Guilford, intelligence is not a single general ability but a combination of multiple abilities. He proposed that intelligence can be understood in three dimensions: operations, contents, and products.

1. **Operations** refer to the types of mental processes involved, such as cognition, memory, divergent production, convergent production, and evaluation.
2. **Contents** are the types of information or material upon which operations are performed, including visual, auditory, symbolic, semantic, and behavioral.
3. **Products** are the forms in which information is processed, such as units, classes, relations, systems, transformations, and implications.

Guilford's model suggests that intelligence is a combination of these three dimensions, resulting in a wide array of intellectual abilities.

Now, let's explain why the other options are incorrect:

1. **Thorndike (Option 1)**: Edward Thorndike is known for his work in educational psychology and the theory of connectionism, which focuses on the association between stimuli and responses. He did not propose the Tridimensional theory of intelligence.

2. **Spearman (Option 3)**: Charles Spearman is famous for his two-factor theory of intelligence, which includes the general intelligence factor (g) and specific factors (s). His theory is quite different from Guilford's multidimensional approach.

3. **Thurstone (Option 4)**: L.L. Thurstone proposed the theory of primary mental abilities, which identifies several distinct factors of intelligence, such as verbal comprehension, numerical ability, and spatial visualization. While his theory acknowledges multiple abilities, it does not align with the tridimensional structure proposed by Guilford.

In conclusion, J.P. Guilford's Tridimensional theory of intelligence is unique in its comprehensive approach to understanding intelligence through the interaction of operations, contents, and products, making Option 2 the correct choice.
