Psychology - Sensory Memory

Psychology - Sensory Memory

1. Duration

   • Fractions of a second.

2. Capacity

   • Very Limited

3. Encoding

   • Unprocessed. Information comes from senses and is held like a copy of the experience.

4. Evidence

   • Sperling 1960
     • Showed a card with letters and numbers to see who could remember them in the exact places they were seen. Most could remember 3 or 4

5. We cannot control what goes into our sensory memory but what we pay attention to gets passed on so most items are lost.

6. Separate sensory stores for different senses.

   • Iconic (sight)
   • Echoic (sound)
   • Olfactory (smell)
   • Haptic (touch)
