7. Does language affect thought? Whorf  “Yes, there is linguistic determination of thought!” Evidence - Tribes that have words describing two similar shades of yellow and better at distinguishing those two shades - The way we use pronouns affects thought; e.g., The nurse returned all his missed calls - Bilinguals describe themselves as having different personalities based on the language in which they are asked But do we need language to think? - The role of imagery; e.g. “mental practice” and dart throwing

16. Environmental influences Schooling effects Early intervention effects Cultural effects

17. Group differences Verbal scores LowHigh MenWomen Within-group difference > Between-group difference Difference diminishing with time Stereotype threat
