These subscales are measured with several different tests. -Verbal scale subtests: finding similarities between 2 words and defining words (to see if you have an extensive vocab). -Performance subtests: picture completions (determine what is missing from a picture) and picture arrangement (organize pictures in a logical order). -Problem with this test: culturally biased. - Raven’s matrices: -Non-verbal assessment of fluid intelligence (=abstract thinking). -Relatively free from linguistic and cultural biases. -People are shown a pattern and asked to fill in a missing piece from a set of options below. -Autistic people perform better at this test than predicted by WAIS or WISC: suggests that these tests predict different facets of intelligence. - Genetics & Intelligence -The heritability in IQ reported between 0.5 and 0.72. -Twin studies show that even if they’re raised in different environments, they have almost an identical IQ score (higher than siblings who live together). -There is an increase in the role of genes on intelligence over time. -Genetic amplification: as we age, we select and modify our own environment based on our genetic make-up. - The environment & intelligence:
