Question
Question 3IQ tests are typically made up of several sub-tests. According to Spearman's two-factor of intelligence, which of the following is true:1 pointa. The 'g' factor explains the similarities among sub-tests, while the 's' factor explains the differences b. The 'g' factor explains the differences among sub-tests, while the 's' factor explains the similarities c. both 'g' and 's' explain the similarities among sub-testsd. both 'g' and 's' explain the differences among subtests
Solution
The correct answer is a. The 'g' factor explains the similarities among sub-tests, while the 's' factor explains the differences.
Spearman's two-factor theory of intelligence includes a general intelligence factor, known as the 'g' factor, and specific factors, known as 's' factors. The 'g' factor refers to the general intelligence that contributes to performance on all cognitive tasks. This is why it explains the similarities among sub-tests - because it is a common factor in all of them.
On the other hand, the 's' factors refer to abilities that are specific to the task. These factors can vary from one sub-test to another, which is why they explain the differences among the sub-tests. For example, a person might have a high 's' factor for a sub-test involving vocabulary, but a low 's' factor for a sub-test involving spatial reasoning.
