Document Summary
Sensory memory: holds raw, unanalyzed sensory information briefly (holds it until we process it, different form/ coding for each sense. Fast movement of a point of light is perceived as a streak instead of a moving dot (we are storing and holding the incoming sensory information) Echoic memory: auditory, lasts 3-4 seconds: ex. Lengths of a speech sound wave must be stored until their component phonemes (or entire words) can be interpreted from it: little research is available on touch/smell/taste memory, experiment-letter arrays. Associating rows with different tones (high, medium, low) Tones played immediately after letter array is removed from view. Cognitive blink suppression: when participants were forced to blink in-between arrays, their memory performance decreased. Miller: 7 + or 2 (depending on the type of item) Capacity limits can be overcome to a certain extend with chunking: multiple working memories items can be stored in a variety of encodings, what you perceive doesn"t always match the storage.
