Sensory Memory

Sensory Memory

1. According to the multi-store model, there is a separate sensory memory store for each of the senses

2. Visual goes into the Iconic Store, Auditory goes into the Echoic Store, Tactile goes into the Haptic Store

   • Sensory stores work as a temporary buffer that hold information from the environment very briefly (0.25-3 sec)
     • Info here is raw, unprocessed, and modality specific, but has a very large capacity

3. Iconic Memory

   • Duration: < 1sec
   • Capacity: Approx. 20 items
   • Level of Awareness: Preconscious, Unconscious

4. Echoic Memory

   • Duration: < or = 3 sec
   • Capacity: 1 to 2 items
   • Level of Awareness: Preconscious, Unconscious

5. According to Sperling we absorb more raw information through visual perception than we can recall in short term memory

   • We consciously block ourselves, we tend to underestimate how good our visual memory is, many people could actually name all 9 letters if pushed
