A) increase attention to non-hostile cues at step 1. B) consider more alternatives at step 4. C) evaluate responses in terms of consequences at step. Intellectual ability differences and social behavior: less clear: distributions of scores for both sexes, overlap but they are statistically different, maccoby and jacklin (1974, clearcut differences only in 4 areas. Aggression m>f: intellectual ability, verbal ability: True in children (so has to be structural) Small but consistent differences: general ability, solving anagrams, quality of speech production. Structural differences: pre natal changes, impact of testosterone. Activational differences: adolescence onward, hormones jumpstart performance change, can be brain related, interacting: mathematical ability: Initially girls excel (computational emphasis) during adolescence boys excel (even when boys and girls are equated for # of math courses taken) Nurture: stereotypic views may affect differences that first emerge in adolescence.
