3 Intelligence and Cognitive Abilities: 1. Do females and males differ in their cognitive abilities?
4 Do females and males differ in their cognitive abilities? A large body of research has examined the cognitive abilities of females and males. This research can be grouped into clusters:
5 Research on sensation and perception: Olfaction: F > M. Taste: F > M. Audition: F > M. Exception: Sound localization. Vision: M > F. Exceptions: Adaptability to darkness, tolerance for high levels of illumination. Males are prone to attend to “mechanical motion,” whereas females are prone to attend to “biological motion.”
6 Research on general intelligence: IQ: F = M. Research on general knowledge: Current affairs, recreation, technology, geography, history: M > F. Medicine: F > M. Psychology, literature, business, art: F = M. Subjective estimates: M > F.
7 Research on verbal ability: Wechsler’s verbal intelligence scale: F > M. Reading fluency and comprehension: F > M. Writing ability: F > M. Verbal memory: F > M. Synonym generation: F > M. Spelling: F > M. Speech articulation: F > M.
8 Dyslexia: M > F. Note that research indicates that teachers “overestimate” the number of boys with reading disabilities. Meta-analysis: d for overall verbal ability is Stuttering: M > F. Sex differences in verbal abilities are consistent across age groups, but appear to be decreasing across time. Hyde (1981, 1988) maintains that gender accounts for only 1% of variance in verbal ability.
9 Research on mathematical ability: Arithmetic computation: F > M. Geometry: M > F. Standardized mathematics tests (e.g., SAT, GRE): M > F. Mathematically-gifted individuals: M > F. Problem solving: M > F. Grades in math classes: F > M.
10 Confidence in and identification with mathematics: M > F. Sex differences in mathematical ability increase across age groups, but appear to be decreasing across time. Meta-analyses: ds for overall mathematical ability range from +.03 to +.26.
