Outline and evaluate the working memory model The working memory model is the part of the short term memory which is governed by the ‘central executive which monitors and coordinates the operation of the store systems; Phonological loop and visuo – spatial sketchpad. The phonological loop allows sounds to be stored for brief periods. The visuo spatial sketchpad allows visual and spatial information to be stored for brief periods. The two slave systems within the WMM are completely separate and can

Outline and Evaluate the Multi – Store Model of Memory ( 12 marks ) Information from the environment enters sensory memory‚ encoded through one of the 5 senses depending on the type of information. If attention is paid to this information it will enter short term memory ( STM )which‚ according to Miller‚ has a capacity of 7+/- 2 bits of information.

Outline & Evaluate The Multi-Store Model Of Memory (12 Marks) The multi-store model of memory is widely renowned as the definitive concept of how our memory works‚ through inter-connected stores. We encode information into our sensory memory by using incoming stimuli (our five senses)‚ our sensory memory is very limited‚ allowing us to only store around 2 items‚ for as little as 1 or 2 seconds. If however‚ we pay attention to the information that has been encoded into our sensory memory‚ it then

Outline and evaluate the multi-store model of memory (12) The multi-store model of memory (MSM) was developed by Atkinson and Shiffrin in 1968 and explains how information flows from one storage system to another‚ with three permanent structures in memory: sensory memory (SM)‚ short-term memory (STM) and long-term memory (LTM). It describes memory as something made up of a series of stores and these each differ in terms of their capacity‚ duration and encoding process. Information is detected

OUTLINE AND EVALUATE EVOLUTIONARY EXPLANATIONS OF FOOD PREFERENCES (4 MARKS + 16 MARKS) Outline (A01) Tastes experiences come from our taste receptors. These make us sensitive to a range of taste qualities. For example‚ sweet foods are usually associated with carbohydrates that are a great source of energy.

This uses the principles of Bandura’s Bobo Dolls experiment which involved children observing aggressive and non-aggressive adults and then acting themselves.
