For precertification of these drugs, callor fax Background Gaucher Disease Gaucher's disease, the most common of the lysosomal storage diseases, is caused by a deficiency of the enzyme glucocerebrosidase that leads to an accumulation of its substrate, glucocerebroside. Glucocerebroside can collect in the spleen, liver, kidneys, lungs, brain and bone marrow. Symptoms of the disease may include an enlarged spleen and liver, liver malfunction, skeletal disorders and bone lesions that may be painful, severe neurologic complications, swelling of lymph nodes and occasionally adjacent joints, distended abdomen, a brownish tint to the skin, anemia, low blood platelets, and yellow fatty deposits on the sclera.
They are being deemed non-scientific and of questionable usefulness. In this blog I will look at both sides of the argument for case studies and see whether as a design it is still useful for the field of psychology. Advantages Case studies allow a lot of detail to be collected that would not normally be easily obtained by other research designs.
The data collected is normally a lot richer and of greater depth than can be found through other experimental designs. Case studies tend to be conducted on rare cases where large samples of similar participants are not available.
An example of this is the study of Phineas Gage by Harlow, J. This example also connects with the point above with the depth of data obtained. Cases of brain damage are quite minimal and it is extremely rare to find people with the exact same parts of the brain affected.
To be able to gain knowledge of brain functions the damage between people have to be exact to ensure you are testing the right thing, this can generally only be done through case studies. Within the case study, scientific experiments can be conducted.
Case studies can help experimenters adapt ideas and produce novel hypotheses which can be used for later testing. Again to Phineas Gage, his contributions to neuropsychology and the workings of the brain are invaluable.
Disadvantages One of the main criticisms is that the data collected cannot necessarily be generalised to the wider population. This leads to data being collected over longitudinal case studies not always being relevant or particularly useful.
Some case studies are not scientific. Freud used case studies for many of his theories or studies. Such examples are that of Anna O and Little Hans. Both of these are not scientific nor are they able to be generalised. This can be attributed to them being case studies, but also Freudian theory in general.
Case studies are generally on one person, but there also tends to only be one experimenter collecting the data. This can lead to bias in data collection, which can influence results more than in different designs.
Case studies also tend to collect mainly qualitative data. I have put this as neither an advantage or disadvantage of case studies, as this depends on your stance on qualitative data.
If you look back a few blogs I have summarised my view of qualitative data.In the social sciences and life sciences, a case study is a research method involving an up-close, in-depth, and detailed examination of a subject of study (the case), as well as its related contextual conditions.
Case study method is particularly useful for theory development and testing and they can be exploratory, explanatory or descriptive (Yin ).
All these types of case study methods are useful in single or multiple case applications (Ghauri and Gronhaug, ). Psychology Chapter 1 Practice Test. Chapter 1: History, Theory, and Research Strategies.
