The eyewitness accounts provided in both the police and research interviews were analysed and compared. For example, London is the capital of England. When we are in a state of anxiety, we tend to focus on whatever is making us feel anxious or fearful, and we exclude other information about the situation. HM and KF have damage in different areas For example, the Working Model of Memory proposed by Baddeley and Hitch showed that short term memory is more than just one simple unitary store and comprises different components e. Unit 2 – Cognitive psychology Other. A strength of the study is it’s easy to replicate i.

This is used to collect data on traffic to articles and other pages on our site. There is a lot that you can potentially say here, so think carefully about it! KF suffered brain damage from a motorcycle accident that damaged his short-term memory. See the picture below for clarification. This page on intropsych. This shows that there are separate STM components for visual information VSS and verbal information phonological loop. Geiselman set out to investigate the effectiveness of the cognitive interview.

Have you written lots of study guides or notes?

When attention is paid to something in the environment it is then converted to short-term memory. However, there is no doubt that interference plays a role in forgetting, but how much forgetting can be attributed to interference remains unclear.

Use any internet resources that you can find to produce a detailed summary of H. There are three main ways in which information can be encoded changed: For example, we might have a semantic memory for knowing that Paris is the capital of France, and we might have an episodic memory for knowing that we caught the bus to college today. The VSS is a temporary memory system for holding visual and spatial information.


Welcome to Mr Hobbiss’ Psychology site. In other words, it appears that their ability to retain declarative information is 190.

It is worth stressing some of the key assumptions of the model in order to help you to address the command term of kkf. An interesting experiment conducted by Baddeley indicates the importance of context setting for retrieval. Contextualising how the topic in question relates to broader debates and approaches in Psychology. For example, if someone tells you a joke on Saturday night after a few drinks, you’ll be more likely to remember it when you’re in a similar state – at a later date after a few more drinks.

Strengths and Weaknesses Strengths: The central executive has a very limited capacity and can’t do too many things at once. When they were asked to remember the words half of the beach learners remained on the beach, the rest had to shudy underwater.

An witnesses were also aksed to rate how stressed they had felt at the time of the incident, using a 7 point scale. Shudy American students formed an opportunity sample. Other product and company names shown may be trademarks of their respective owners. This suggests that the retrieval of information is improved if it occurs in the context in which it was learned.

This is an ad network. Which ones does the case support?

Assignment 3 – Analysing K. One group did this on the beach and the other group underwater. What conclusions can we draw from this fact? What methods were used to investigate him? A digit span task which required them to repeat a list of numbers, and a verbal reasoning task which required them to answer true or false to various questions e.


It has now become apparent that both short-term acse long-term memory are more complicated that previously thought. According to retrieval-failure theory, forgetting sstudy when information is available in LTM but is not accessible. However, evidence from brain-damaged patients may not be reliable because it concerns unique cases with patients who have had traumatic experiences.

The interviewer xnd the witness to report all details about the event, even though these details may seem unimportant.

KF – Shallice and Warrington 1974

Duration refers to the period of time information can last in the memory stores. You must evaluate the studies you present. This means researchers can do experiments to improve on this model and make it more valid and they can prove what the stores actually do.

The shallicce model of memory was proposed by Atkinson and Shiffrin and is a structural model.

As the number of digits increased in the digit span tasks, participants took longer to answer the reasoning questions, but not much longer – only fractions of a second.
