It can process information in all sensory forms, directs information to other slave systems and collects responses. This is absolutely crucial! Corkin et al H. Look back at the assumptions of the Multi-Store Model of Memory above. The results of the study showed the witnesses were highly accurate in their accounts, and there was little change in amount or accuracy shalljce recall after 5 months.

Types of cues that have been studied by psychologists include context, state and organisation When we store a new memory we also store information about the situation and these are known as retrieval cues.

Animal research also raises the issue of extrapolation. The witnesses were also aksed to rate how stressed they had felt at the time of the incident, using a 7 point scale.

The basic idea behind state-dependent retrieval is that memory will be best when a person’s physical or psychological state is similar at encoding and retrieval. Proactive and retroactive Interference is thought to be more likely to occur where the memories are similar, for example: Because he wasn’t moving obviously they were able to scan for nine hours in astonishing detail.

For example, research has shown that using a combination of ‘report everything’ and ‘context reinstatement’ produced better recall than any of the conditions individually. Working memory is supported by dual task studies. The marking criteria are below.


One of the very influential early models of how our memory works was the Multi-Store Model of Memory Atkinson and Shiffrin, A more detailed summary of the numerous studies involving H.
