The purpose of this study was to determine whether timing of puberty is related to spatial ability in adult women, and whether, if so, the relation could be attributed to timing-related differences in hemispheric specialization and/or timing-related differences in personality and spatial activity. 53 female undergraduates were given 2 tests of spatial ability, tests of both right-hemispheric and left-hemispheric specialization using tachistoscopic procedures, several tests assessing masculinity and femininity, and a questionnaire on spatial activity. They were also asked to recall their age at menarche. Later age at menarche was associated with greater right-hemispheric advantage on the dot location task but not with higher spatial ability. Spatial ability in this sample was in fact correlated with greater left-hemispheric advantage on the dot location task, as well as with more balanced hemispheric specialization on the syllable task. It is suggested that variability in findings regarding cognitive correlates of timing of puberty may be related to variability in strategies for approaching tasks. The implications of these data for efforts to explain sex-related differences in spatial ability are discussed. |
