Who created the Wechsler Scales used for intelligence testing?

David Wechsler is the correct answer because he developed the Wechsler Scales, which are widely used for measuring intelligence in both children and adults. The Wechsler Intelligence Scale for Children (WISC) and the Wechsler Adult Intelligence Scale (WAIS) reflect a departure from earlier intelligence tests by focusing on a broader understanding of cognitive abilities rather than a single measure of intellect. Wechsler emphasized a more comprehensive approach to assessing different aspects of intelligence, including verbal and performance skills, which has greatly influenced psychological assessment and practice in social work and related fields.

In contrast, Alfred Binet is known for creating the first standardized intelligence test, which laid the groundwork for later developments in intelligence testing but was not responsible for the Wechsler Scales. William Stern contributed to the concept of the intelligence quotient (IQ), while Charles Spearman is noted for his work on the idea of general intelligence (g factor), neither of whom developed the Wechsler Scales. By focusing on multiple dimensions of intelligence, Wechsler's work allows for a more holistic understanding of an individual's cognitive strengths and weaknesses, which is valuable in various applications, including educational settings and clinical assessments in social work.
