Document Summary
Increases in two broad areas: capacity (hardware, memory span (of stm, processing speed, strategy use (executive function) (software, proficiency. Development of the short-term store (working memory capacity) Usually assessed with tests of memory span: unrelated items that can be recalled in order. Processing speed may be another factor accounting for age related differences in memory tasks. Young children require more time and use more resources (more of their limited capacity) to execute cognitive processes. The results of these limitations are seen on several memory tasks. Constraints on time and resources/capacity translate into poorer performance on wm tasks. Tasks varied in cognitive requirements, difficulty: name retrieval, mental addition, visual search, mental rotation, memory search. Results: pattern of response across the varied tasks was the same across age (faster rt = increased speed) Common trend across tasks implies change in basic processing capacity. With age, kids use their capacity more efficiently.
