A Developmental Evaluation of Frequency Memory for Actions Presented in Lists and Scripts.
Connolly, Deborah A.; Hockley, William E.
Two experiments tested Hasher and Zacks' (1984) age-invariance hypothesis of frequency memory, which proposed that frequency memory is fully developed when a minimal level of physiological maturation is reached (by two or three years of age). Participating in the first experiment were 24 subjects at each of three ages: 8 years, 11 years, and young adults. In the second experiment, there were 24 subjects at each of 4 ages: 6 years, 8 years, 11 years, and young adults. In both studies, children and adults heard atypical action statements, presented as many as seven times, either in list format or embedded in script-like stories. In the first experiment, frequency estimates were higher for actions presented in list format, and age differences were found between 8- and 11-year-old children and adults. In the second experiment, frequency estimates were unaffected by the presentation format, and age differences were found only between 6-year-old children and adults. Results from both experiments suggests that frequency memory is fully developed by 6 years of age. Overall, results supported the age-invariance hypothesis and provided novel support for the Script-Pointer-Plus-Tag theory of script memory. (MM)
