Question

Who is known as the “father of measurement of intelligence”?

• A. Alfred Binet
• B. Cattell
• C. Spearman
• D. Buckingham \medskip \textbf{Correct Answer:} (A) Alfred Binet \medskip

Hint:

“First usable test + mental age” \(\Rightarrow\) Binet–Simon.

Answer 1

The Correct Option is A

Step 1: Historical anchor. Alfred Binet (with Théodore Simon) devised the first practical {intelligence scale} (1905), introducing the idea of {mental age}.
Step 2: Distractors. Cattell coined “mental tests” (1890) but not the IQ scale; Spearman gave the {g} factor/two-factor theory; Buckingham is not credited with founding intelligence measurement.
Step 3: Conclude. \[ \boxed{\text{Alfred Binet (Option A).}} \]
