Document Summary
Human: first stage of information processing (perception, stimulus identification, recognition that a stimulus is present (sensation, typically a change in the environment. Interpret a selection of information to form a representation of change in environment to determine what stimulus is. Sensation and perception: sensation, low-level neural and biochemical events at level of receptors and earliest coding structures. Identifies that stimulus is there: can"t generate action with low-level info, perception, cognitive and attention demanding process of drawing meaning from sensations, takes more mental effort, matching of stimulus features to a memory. Memory: encoding (neural representation of features), storage, and retrieval of information, sensory stores, limited capacity, < 1 second, short-term or working memory things thought about at a moment of time. Kpe160: limited capacity, seconds to a minute, long-term memory, large, but limited (only so many neurons), capacity and duration, sometimes one-time learning happens once and goes straight to long- term (eg. location of light switch)
