Who is the proponent of the Wechsler-Bellevue Intelligence Scale?
Detailed Explanation
📌 Core Theoretical Concept:
The Wechsler-Bellevue Intelligence Scale was developed by David Wechsler in 1939. David Wechsler revolutionized intelligence testing by creating individually administered tests designed specifically for adults and later for children, addressing the limitations of earlier verbal-heavy tests like the Binet-Simon scale. Wechsler defined intelligence globally as the capacity of an individual to act purposefully, to think rationally, and to deal effectively with their environment. His scales introduced a combination of verbal and performance subtests, providing a comprehensive profile of an individual's cognitive strengths and weaknesses.
📊 Key Exam Points:
- David Wechsler developed widely used scales such as WAIS (Adults), WISC (Children), and WPPSI (Preschoolers).
- Option (a) Jean Piaget is renowned for his theory of Cognitive Development.
- Option (b) Ivan Pavlov formulated the theory of Classical Conditioning.
- Option (c) Clark Hull proposed the Drive Reduction Theory of learning and motivation.
📖 Theoretical Reference: Wechsler's scales introduced the concept of Deviation IQ, replacing the traditional mental age concept. For comprehensive study materials, check Intelligence Testing & Assessment.

Deep Pedagogical Analysis & Exam Strategies:
Questions regarding intelligence test creators are frequent in teacher eligibility tests like CTET, UPTET, and various state TETs. Understanding Wechsler's approach helps educators recognize individual differences in cognitive profiles. Unlike group tests, Wechsler scales allow educational psychologists to assess specific sub-skills like working memory and perceptual reasoning, aiding in the identification of learning disabilities and giftedness among students.
