CHYS 2P10 Lecture Notes - Lecture 6: Wechsler Intelligence Scale For Children, Dyslexia, Theory Of Multiple Intelligences
Document Summary
Intelligence is a trait or set of traits on which individuals differ. To determine intelligence, they sought to examine items that were correlated with high teacher ratings. From this they developed the binet-simon test of intelligence, which gave a score in terms of the child"s mental level (also referred to as mental age) These tests were eventually modified in the u. s. a. to become the stanford-binet test. This test reported test scores in terms of intelligent quotient (iq), which was a function of the mental age of the child divided by their actual physical age. Adult version is the wais-iii, child version is the wisc-iii. Intelligence quotient calculated as iq = mental age/chronological age *100, but all modern tests now use deviation iqs. Tests include both verbal and nonverbal (performance) measures. Sir francis gelton believed that intelligence was based on biological differences in the speed of neural conduction.
