Summary sheet of Cognitive Case studies
In addition to lab experiments, cognitive psychology will sometimes use case studies of brain injury
in their research.
1. What is a case study?
Case studies are a type of research investigation that involves a detailed study of a single
individual, institution or event.
2. What type of information can case studies give?
They can provide rich and detailed information about the brain and its functions. They are
highly subjective and idiographic.
3. What are the strengths of using case studies?
They can give rich, qualitative data that could not be obtained during experiments. They put
psychology into the context of real life and as they cannot be replicated and are idiographic,
they can provide insight into the workings of the mind
4. What are the weaknesses?
However, as they are generally extraordinary cases, they can sometimes be too unrealistic
that the findings cannot generalise to everyone. They are also idiographic in nature, as they
are studying one person in detail; so again, the data is unique to that person and cannot be
fully proven, as the cases are not replicable.
Examples of case studies
Phineas Gage- We learnt that the frontal lobes affect our personalities, as Gage's
personality drastically changed after he received damage to that area of his brain.
Split brain patients- Done to treat patients with severe epilepsy. We learnt that the brain's
left and right side has different functions.
The case of Clive wearing- Amnesia patient, we learnt from him the importance of memory
in our lives and significantly, how emotional and creative memories are particularly
important, as Clive could only remember his wife and how to play the piano.
Imposter delusion-This is where the part of the brain that gives an emotional response to
recognition is damaged. Therefore, the individual can recognise and name their loved ones,
but believe they are an imposter as they have no emotional response on seeing them.
