Which psychologist first created the intelligence test?

Correct option is B

Alfred Binet, a French psychologist, was the first to create an intelligence test in the early 20th century. In 1905, along with his colleague Théodore Simon, Binet developed the Binet-Simon Intelligence Scale to identify children in need of special education support. This test measured cognitive abilities and provided an intelligence quotient (IQ) score, which later became the foundation for modern intelligence testing.

Information Booster:

• Binet-Simon Scale (1905): The first-ever intelligence test, designed to assess the mental abilities of children.
• Purpose of the Test: It was originally developed to help identify students who needed additional academic assistance in France.
• IQ Concept Development: The test introduced the idea of mental age, which compared a child's performance to the average ability of children in a specific age group.
• Influence on Modern IQ Tests: The Binet-Simon Scale inspired later intelligence tests, including the Stanford-Binet Intelligence Scale used widely today.
• Contribution to Educational Psychology: Binet’s work emphasized that intelligence is not fixed and can be improved through education and training.
• Recognition and Influence: His work influenced later psychologists like Lewis Terman, who modified and popularized the test in the United States.

Additional Information:

• Wechsler: David Wechsler developed the Wechsler Adult Intelligence Scale (WAIS) and Wechsler Intelligence Scale for Children (WISC), which are widely used today for intelligence assessment.
• Spearman: Charles Spearman proposed the g-factor theory, which suggests that intelligence is a single, general ability influencing all cognitive tasks.
• Cattell: Raymond Cattell introduced the concepts of fluid intelligence (Gf) and crystallized intelligence (Gc) to explain different types of cognitive abilities.
