Evaluate two models of theories of memory.

This essay will evaluate two models of theories of memory. Memory can be defined as the persistence of learning over time via the encoding, storage, and retrieval of information. Encoding is the process of categorizing incoming information through conscious effortful processing, rehearsal, or unconscious automatic processing. The storage process involves the retention of encoded information over time. Lastly, retrieval is the process of getting information out of memory. There are various types of memory. Sensory memory is the immediate, initial recording of sensory information in the memory system. It also plays a vital role in filtering out useless information, enabling us to focus our

Some information from the sensory store moves to the STM by paying attention to information, while some information from the STM moves to the LTM via constant rehearsal of that information. Once that piece of information is stored in the LTM, it is long-lasting - perhaps even for a lifetime if that certain piece of information is that strong. The difference in forgetting between the STM and LTM is that memory forgotten from the short term store is lost whereas forgotten memories in the LTM are still in the system but cannot be retrieved. The sensory, short-term, and long-term memory stores also differ from one another in regards to duration (how long information can be stored), capacity (how much information can be stored), and coding (in what form information can be stored). The sensory store decays rapidly, has unlimited capacity, and the information is picked up by our senses. Sensory memory includes iconic (visual), haptic (touch), and echoic (auditory) memories as well. STM lasts 15-30 seconds, is limited to 7 plus/minus 2 units, and is coded acousting. The information in STM is lost unless it is rehearsed via repetition. On the other hand, LTM can potentially last a lifetime, has unlimited capacity, and the information stored is primarily semantic but also acoustic and visual. The strengths of the multi-store model include: it stimulated further research into memory processes; it has considerable evidence for
