Question 8
Assess whether case studies of brain-damaged patients are an effective method for investigating human memory.
Worked Solution & Example Answer:Assess whether case studies of brain-damaged patients are an effective method for investigating human memory. - AQA - A-Level Psychology - Question 8 - 2020 - Paper 1
Step 1
Research using case studies of brain-damaged patients
Answer
Case studies of brain-damaged patients can provide in-depth qualitative data, offering insights into the workings of human memory. Each case presents unique characteristics, as brain damage is not uniform across all individuals. The detailed descriptions obtained through these studies help to paint a fuller picture of memory functions that would be difficult to capture with other methods.
Step 2
Effectiveness and limitations of brain damage studies
Answer
While these studies can yield rich qualitative information, they also have limitations. Case studies are often unique and not generalizable due to the atypical nature of brain injuries. Additionally, other research methods such as observations, PET scans, and experimental techniques may provide more controlled and replicable findings regarding memory functioning.
Step 3
Validity and Triangulation
Answer
Qualitative data from these case studies can enhance the validity of findings, particularly when combined with diverse methodologies. By employing a triangulation strategy, researchers can corroborate findings from case studies with other methods, thereby increasing the scientific credibility and rigor of their conclusions regarding memory.
Step 4
Longitudinal studies and developmental differences
Answer
Utilizing longitudinal studies on brain-damaged patients allows for the observation of changes over time. This can provide insights into memory functioning and developmental differences, especially in neurodegenerative disorders such as Alzheimer’s. Tracking individual cases over a prolonged period offers opportunities to assess both the stability and evolution of memory functions.
