The emergence of strategic verbal rehearsal at around 7 years of age is widely considered a major milestone in descriptions of the development of short-term memory across childhood. Likewise, rehearsal is believed by many to be a crucial factor in explaining why memory improves with age. This apparent qualitative shift in mnemonic processes has…

Used a variance-partitioning procedure to identify age-related and age-invariant components of verbal and spatial memory span in 6- to 12-year olds. Concluded that verbal and spatial short-term memory appear to rely on similar processes when serial recall is required and that development in span is closely tied to increases in processing speed.…

This study, involving 24 young and elderly normal-hearing adults, addressed the effects of aging on auditory serial-recall performance for natural and synthetic words. Serial recall of monosyllabic words was not affected by age per se or by rate of presentation, but word difficulty affected recall for both groups. (Author/JDD)

Retarded subjects were compared with mental- and chronological-age matched controls on serial short-term memory (STM) tasks. Retarded subjects were inferior to the control groups on both primacy and recency items, under two recall conditions. These data are discussed in relation to possible mechanisms underlying IQ-related individual differences…
