Document Summary
Memory - the retention of information over time. Memory illusion - false but subjectively compelling memory. Span - how much information each system can hold. Duration - over how long a period of time that system can hold information. These systems serve distinct purposes and vary along at least two important dimensions: Sensory memory - brief storage of perceptual information before it is passed to short-term memory. Holds for a duration of a few seconds or less before being passed on to next level. Short-term (working) memory - memory system for retaining information in our memories for brief periods of time. Working memory - refers to our ability to hold on to information we"re currently thinking about. Explanations for the loss of information from short-term memory. Decay - fading of information from memory over time. Birth of new neurons in the hippocampus leads to the decay of memories in that brain region.
