Correct Answer - Option 4 : Alfred Binet
  • The first modern intelligence test was developed in 1904, by Alfred Binet (1857-1911).
  • He was one of the most influential psychologists in history.
  • He designed a series of questions with the objectives to distinguish children who may have learning disabilities and mental retardation.
  • His test was based on assumption that intelligence developed with age.
  • Binet concentrated on mental abilities such as attention and memory, it may be used to identify children who needed additional academic assistance.
  • Binet worked with his research assistance 'Simon' and introduced an intelligence test, known as the Binet-Simon Intelligence scale.
  • The test consists of 30 different questions or tasks and the goal of the task was to assign a child a mental age based upon the average performance of children at each age.

Hence, the first intelligence test was developed by Alfred Binet.

Intelligence testing:

  • An Intelligence Test is an assessment that measures the range of intellectual, memory, speed, attention, reasoning abilities, and cognitive abilities.
  • Generally, Intelligence tests are designed specifically to assess human intelligence through the performance of various tasks.  
  • Intelligence Quotient is the measure of a child's ability to reason and solve problems. 
  • IQ is correlated either directly or indirectly with problem-solving and educational performance.

Intelligence Quotient (IQ) can be obtained by the equation (MA/CA) * 100 = IQ, where MA is mental age and CA is chronological age.

  • Mental Age is the measure of the intellectual level at which an individual functions; for example, someone described as having a mental age of 8 years would be functioning at the level of an average 8 years old.
  • Chronological Age is the number of years a person has been alive
