Answer:
Intelligence
During the early 1900s, the French government asked Binet to help decide which students were most likely to experience difficulty in school. The government had passed laws requiring that all French children attend school, so it was important to find a way to identify children who would need specialized assistance.
Binet and his colleague, Theodore Simon, began developing questions that focused on areas not explicitly taught in schools, such as attention, memory, and problem-solving skills. Using these questions, Binet determined which ones served as the best predictors of school success.
He quickly realized that some children were able to answer more advanced questions that older children were generally able to answer, and vice versa. Based on this observation, Binet suggested the concept of mental age, or a measure of intelligence based on the average abilities of children of a certain age group.
