Which test was developed by Lewis Terman and is used to assess general cognitive ability based on Binet's original scale?

• A. Wechsler Scales
• B. Gardner's Multiple Intelligences
• C. Stanford-Binet Intelligence Scale
• D. Emotional Intelligence

Answer: (C)

This test is the Stanford-Binet Intelligence Scale, a revision of Binet’s original assessment that Lewis Terman developed at Stanford to measure general cognitive ability across ages. It was designed to yield a single index of intelligence by comparing a person’s performance to normative data and their age, capturing the idea of a unitary general mental ability. That focus on a broad, overall measure of cognition—rooted in Binet’s original concept—is why this is the best answer. The other options point to different ideas: Wechsler scales are another family of intelligence tests designed with different structure and subtests; Gardner’s theory emphasizes multiple distinct intelligences rather than a single general ability; Emotional Intelligence refers to skills in recognizing and managing emotions, not a general cognitive ability test.
