Question

Connecting to at least 2 facts for each theory compare Atkinson–Shiffrin three-stage model with Baddeley’s rehearsal systems approach. Include an example of information that is within each stage of the memory system to illustrate what type of information each memory system holds.

Answer 1

Memory means a system exists in our mind through which we basically try to take in various information. After the input of information we also try to store it so that it can be recalled at later stages and at suitable time.

So, three processes remain involved in memory building. These processes are; encoding of information, storage of information and retrieval of information. Atkinson and Shiffrin gave a theory of structural model of memory.

They proposed that there are three stores of memory which includes long term memory, short term memory and a sensory register. Short term memory is basically known as working memory. It lasts up to 20 seconds only. Long term memory keep on storing information for a longer period of time. Sensory memory basically remains involved in storage sensory information for a brief span of time.

Baddeley also proposed a working modal of memory. According to this model; there are basically three loops. One is phonological loop. Another one is Visuo-spatial sketchpad and third one is Central Executive.

Phonological loops processes sound. It is responsible for processing of speech based information. Visual and spatial sketchpad remains related with visionary information and space related information.

Central executive performs perplex functions. It remains related with multitasking. It is also responsible for selective attention through which irrelevant information are suppressed.
