Document Summary
The information processing model: theory of how we expect information should pass through our memory systems, computer analogy mental hardware and software with input devices, ram, storage and a central processing unit. Information processing in older children: working memory capacity and efficiency, development of strategy us. Extent and how we use strategies change: role of knowledge. Starts with sensory input -> sensory memory -> attention/preference -> short term and working memory long term. 0. 5-3 sec: rehearsal strategies are used here, unrehearsed info lost in 10-15secs. Short term/working memory: site of ongoing cognitive activity. Central executive: analogous to cpu or operating system, responsible for all the movement of information, execution of needed responses, cognitive abilities and strategy selection for particular goals. Can i understand it and therefore store it in ltm: with each word coming in, you infer meaning from ltm to understand sensory input.
