Question

Quizplus · Accepted Answer

The best choice is D, general intelligence (g), as it describes the idea that there is a core ability or factor that contributes to performance across various intellectual tasks. This concept has been supported by research in psychometrics and is one of the most widely accepted theories of intelligence. Option A, gainful loss (gl), is not a recognized concept in the study of intelligence. Option B, general mental age (gm), is a term commonly used in developmental psychology to describe a child's overall level of cognitive functioning, but it does not apply to adults and is not a comprehensive measure of intelligence. Option C, mental giftedness (mg), describes an exceptional level of intelligence or talent in a specific area, but it does not encompass the broader idea of general intelligence.
