Document Summary
How specific components of cognition help us think about cognitive development: general processing speed/automaticity, capacity of wm systems, changes in executive functions and inhibitory processes, growth of strategies, expansion of domain-specific knowledge. Information processing approach: working memory like a computer, how much information we can hold at one point in time and how efficiently we can manipulate that information, capacity and manipulation. Memory span: how much information you can hold at one point in time, set of numbers, how many you can remember, 8567123. Keying in on visual similarity: for 10 years old, the visually different, phonologically similar list is easier to remember. Changes in inhibitory processes, miller & weiss (1981), 7 v. 13 year olds: attentional control, young adults have the best cognitive system, and can"t switch attention. Semantic memory: memory of general knowledge, storehouse of knowledge, grows with experience, development of semantic memory over time is helping underlie other sorts of cognitive abilities.
