Alfred Binet's insight regarding a method of measuring mental development had an international impact in the twentieth century. Explain how he went about calculating a child's mental abilities
What scoring system did later researchers base on Binet's method, and how was it originally calculated?
What will be an ideal response?
Answer: A good answer will include the following key points.
• Binet's test included items ranging from those that most young children could do easily to those that only older children could handle.
• The test was given to large numbers of children and the typical performance for each age was determined.
• This allowed him to determine a child's mental age, the level of intellectual development relative to other children.
• The purpose of Binet's test was to determine which children were slow learners so that they could be given remedial work and brought up to the average.
• Later researchers used Binet's concept of mental age to calculate an intelligence quotient (IQ) score for individuals.
• Originally, IQs were calculated by dividing a child's mental age by his or her chronological age and then multiplying by 100.
