Document Summary
Bi(cid:374)et"s i(cid:374)tellige(cid:374)ce test: developed a set of intellectual tasks that became model for current intelligence tests, first used to identify children needing additional educational programs, mental age is not always equal to chronological age. Reasoning, thinking, and problem-solving all depend on intelligence. Intelligence can be improved with practice: stanford-binet (lewis termin) English version of binet tests; allowed ranking. Added items to measure adult iq, not just children: wechsler scale. Consist of 7 verbal and 7 performance scales which could be scored separately. Verbal: based on language and cultural knowledge. Performance: such as spatial ability and capacity to manipulate objects. Reasonably good validity for predicting certain criteria like performance in school: standardized. Same items, same conditions for each test taker: norms. The average score at each age level is assigned the iq value of 100. What do results tell us: ability to address groups differences. Impact of context on test performance and interpretation.
