HM had suffered very bad epilepsy from age 16. Normal STM but unable to lay down new information in LTM, some LTM left unaffected as remembers who is wife is and other skills like playing piano and conducting. Lives in a snapshot of time, constantly believing he has just woken up from unconsciousness A virus attacked and destroyed his hippocampus and also damaged other areas of cortex. Participant and researcherĬlive Wearing was chorus master of London Sinfonietta, BBC radio producer and world music expert. This is shown by HM and Clive Wearing’s unaffected procedural memories. Case studies like these indicate that there are different memory stores but perhaps it is too simple to think that there are only three stores, memory for different types of information seems to be situated in different areas. The table below details three case studies conducted with people with brain injuries. This is clearly not always the case but worth bearing in mind □ Often there is no valid evidence of the person’s skill level prior to the brain injury, and therefore it is not possible to conclude with certainty that the brain injury has caused any issues the person appears to have, as these problems may have pre-dated the injury. The use of multiple research methods is known as method triangulation.Ĭase studies generally lack control as the injury was naturally occurring, this said, they can inspire more scientific studies that are able to examine cause and effect.Īs you may recall from the localisation topic, case studies focusing on people who have sustained brain damage allow researchers to explore the function of various brain regions through examining the impact of the damage on their behaviour and cognitive functioning.Ĭan you think of any scientific weaknesses of such studies? they have been involved in an accident, had an illness that has affected their brain or undergone surgery for a tumour or to treat epilepsy, for example.Ĭase studies focuses on an individual or small group and use information from a variety of sources including medical and educational reports and records, interviews, standardised tests and observations, and so on to gather a wide range of detailed information. Clearly, from an ethical standpoint we cannot deliberately injure someone purely to see what behavioural and cognitive changes may result! Instead, scientists often make use of naturally occurring cases where someone has an acquired brain injury, meaning they were functioning perfectly well beforehand, i.e. What is a case study?Ĭase studies allow us to gather in-depth information on areas where it may be impossible to carry out experiments. Case studies of people with acquired brain injuries have been particularly useful in providing support for one of MSM’s key claims, but the same studies have also highlighted some of the weaknesses of this model. In your essay, it is important that you are able to link research evidence to specific theoretical claims.
