This investigation sought to determine if a relationship between rate of pubertal development and cognitive styles, previously observed in early adolescents, holds over time. In contrast to reports that early and late maturers, as early adolescents, have different patterns of cognitive abilities, two studies failed to confirm a relationship between maturation rate, indexed by age at menarche, and (1) spatial ability, (2) verbal fluency, or (3) relative degree of spatial versus verbal fluency in late-adolescent women. The results suggest a developmental instability of maturation-rate/cognition relationships, at least among females.
