Case studys Flashcards
Case study?
using the details of a case of an indivisual or group of indivisuals or an event
picked due to some unusual trait, life experience or wider event within society
using past records (including medical), interviews (qualitive), questionaires (quantitive) and observations
mainly used if the thing we are studying would be unethical to create/conduct in a lab experement e.g. brain damage
Strength of case studys
ethics
Ethical as can study unethical things such as brain damage without having to artificialy create it in a lab, reducing physicial halm to the ppt therefore making it more ethical than a traditional lab study.
Weakness of Case study
internal Validity
Due to case studys usualy being picked to be studyes due to having brain damage, which helps in theory determin what a part of the brain that is damaged does by comparing the behaviour of the brain damaged ppt and a non damaged one
however we cannot be 100% sure that the brain damage is the cause of the difference in behaviour as other damage near that area of the brain may have caused the behaviour change
this means that we cannot accuratly establish cause and effect and therefore case studys have low internal validity
Strength of case study
longituduinal valididt
Case studys oftern take place over a long perioid of time (longituduinal) this means that the data recorded overtime can reveal patterns in development and change in behaviour. As data is collected all the time, over time, it gives case studys longituduinal validity
Weakness of Case study
generalisability
A weakness of case studys is that due to being used for their indivisual difference and uniqueness (mainly brain damage) ppt’s results cannot be generalised to the whole population as their (usualy brain structure/damage/experiences) are completly unique and cannot be generalised to anybody else
giving case studys
low generalisability
