Properties of memory stages: capacity: how much information it can hold, duration: how long information stays there. Sensory memory: holds sensory impressions that persist after the original stimulus has ended . Example: hand wave it in front of your face. Your fingers are not actually there they were just there. Thus, this memory was preserved for just a short period of time after the stimulus is no longer there where you"re seeing it. Attention: you can remember what your mom said when you weren"t listening right away. Visual = icon memory: ex: firework, or hand wingled in front of your face, duration: < 1 sec, capacity: large. But then replay your conversation: < 4 sec, capacity: large, machines. Tachistoscope: presents images for precise, brief period of time.
