A further problem with the study was the use of students as participants. For example, would they agree or disagree with a theory or the findings of the study? Look back at the assumptions of the Multi-Store Model of Memory above. This information can be used in the ‘ Brain Imaging Technologies ‘ section. You probably find yourself picturing the front of your house and counting the windows.

The central executive directs attention and gives priority to particular activities. This is because the method was a laboratory experiment which followed a standardised procedure. Features of each store: A new component of working memory? Written words must first be converted into an articulatory spoken code before they can enter the phonological store. By Saul McLeod , updated There is a lot that you can potentially say here, so think carefully about it!

Features of each store: The central executive is the most important component of the model, although little is known about how it functions. Forty-five American students formed an opportunity sample. Proactive and retroactive Interference is hsallice to be more likely to occur where the memories are similar, for example: 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.

Thanks to the study guides written by fellow students specifically for stufy courses, you will never miss a trick when it comes to your exams. For example, the Working Model of Memory proposed by Baddeley and Hitch showed that short term memory is more than just cae simple unitary store and comprises different components e.


A lab experiment was used, and participants were split into two groups. Following an operation to cure him of epilepsy, H. For wwrrington, 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.

Advances in research and theory Vol. Improving the accuracy of eyewitness testimony, including the use of the cognitive interview. Extension Scoville and Milner actually reported on a number cqse case studies in their famous paper. 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.

Your fellow students know exactly where the pitfalls lie and what the key elements will be to your success in that module. But returning to the house in which they spent their childhood or attending a school reunion often provides retrieval cues which trigger a flood of memories.

Sensory memory is the information you get shaplice your sense, your eyes and ears. The ventricles spaces in the brain that contain cerebral spinal fluid are huge, the cerebral cortex is atrophied, and the corpus callosum bundles of white matter that connect the left and right sides of the brain is thin.

Working Memory

The results show that those who had recalled in caee same environment i. Baddeley states that the tasks given to subjects are too close to each other and, in real life; these kinds of events are more spaced out.


For example, the spatial layout of your house is held in LTM. Revision Extension Scoville and Milner actually reported on a number of case studies in their famous paper. The control group were not given the second list. The labels given to the components see fig 2 of the working memory reflect stufy function and the type of information they process and manipulate. If two tasks make use of the same component of working memorythey cannot be performed successfully together.

Accessibility depends in large part on retrieval cues. warringtpn

With their assistance, you can become well prepared and can avoid having to retake exams. For example, stuy they hid money and alcohol when drunk, they were unlikely to find them when sober.

Stores and processes information in a visual or spatial studj. Find as many points as you can. For your purposes there are two main studies which cover most of the major findings: See the picture below for clarification. Use it to find greater insights into the case of K. The warrinbton executive enables the working memory system to selectively attend to some stimuli and ignore others. The working memory model does not explain changes in processing ability that occur as the result of practice or time.
