Document Summary
* information-processing model_* sensory memory_* attention_* short-term memory_ Encoding is the processing of information into the memory system. Storage is the retention of encoded information over time. Retrieval is the process of getting information out of memory storage. What are the stages of memory as described in the atkinson- Sensory memory is a very brief memory that is based upon a sensory register. The information in this memory store is: (a) relatively raw and unprocessed (b) passively recorded (c) a fairly accurate representation. Iconic memory is a temporary visual buffer that holds information for a brief period of time (250-300 msec). After the time, the data begins to decay or incurs interference from subsequent visual information. Visual persistence is the apparent persistence of a visual stimulus beyond its physical duration. Echoic memory is a temporary auditory buffer that holds information for a brief period of time (2-4 sec). Selective attention is the focusing of conscious awareness on a particular stimulus.
