In a study, researchers administered a battery of cognitive tests to 500 adults. They found that performance on vocabulary, mathematical reasoning, spatial rotation, and processing speed were all positively correlated. A factor analysis extracted a single dominant factor that accounted for a substantial portion of the variance across tests, while leaving smaller residual variance unique to each subtest.
A theorist who argues that this single-factor finding overlooks distinct musical, interpersonal, and bodily-kinesthetic abilities is best aligned with

Binet's mental age concept

Gardner's theory of multiple intelligences
Explanation
Gardner argues for multiple, relatively independent intelligences (e.g., musical, interpersonal, bodily-kinesthetic) that a single g factor fails to capture.
