Final answer:
Howard Gardner would agree with the statement, as he developed the Multiple Intelligences Theory, which identifies spatial, body-kinesthetic, and intrapersonal as distinct types of intelligence.
Step-by-step explanation:
The psychologist who would agree that an architect likely has good spatial intelligence, a gymnast or dancer likely has good body-kinesthetic intelligence, and a psychologist probably has good intrapersonal skills is Howard Gardner. Gardner developed the Multiple Intelligences Theory, suggesting that there are eight distinct intelligences. The mentioned intelligence types - spatial, body-kinesthetic, and intrapersonal - are part of his theory. This classification reflects the notion that intelligence is multidimensional and that each individual possesses a unique combination of these intelligences.
