- Memory according to MSM
- Sensory memory - initial contact for stimuli/info.
- This receives incoming information from the senses.
- It is modality specific which means information from each sensory system is encoded in the corresponding format.
- Three types of sensory store: iconic memory, for vision, echoic memory, for hearing, and the haptic memory, for touch.
- The duration of memories is very short. The capacity is surprisingly large (Sperling 1960)
- Forgetting occurs by decay although it may also happen because information has not been attended to.
- Short-term memory - the info that we are currently aware of or thinking about.
- This store receives information from the ** and it uses rehearsal to transfer info to LTM.
- Limited capacity of 7+/-2 chunks or items and a duration of 30 seconds.
- Forgetting occurs by displacement if info enters STM more quickly than it can be consolidated and transferred to LTM.
- Much of STM is encoded in an acoustic form.
- Long-term memory - continual storage of info which is largely outside of our awareness, but can be called into the sensory memory to be used when needed
- Encoding in LTM is semantic.
- Capacity is limitless and the duration is up to a lifetime.
- Forgetting occurs by decay, retrieval failure or interference.
- Retrieval may use several mechanisms including various kinds of cues, such as context and state.
- Sensory memory - initial contact for stimuli/info.
