WEAKNESSES OF USING CASE
STUDY TO INVESTIGATE
Researcher bias
SCHIZOPHRENIA
SCHIZOPHRENIA
Researcher personal beliefs, subjective
Develop relationship - patient
Influence interpretations
Low in population
validity
Only 1 patient, eg. Conrad- right drug
Schizophrenia symptoms - unique
Cannot generalise findings of treatment to everyone
Raise ethical
issues
Informed consent not given before giving drug/ ECT

GENERALISATIONS
FROM FINDING
LOW ECOLOGICAL
VALDITY
Use of Virtual Reality
does not resemble real life settings
people don’t go through VR on a
daily basis
people asses other‘s action based on
real life situations or encounter
LOW POPULATION
VALDITY
Small sample size
only 24 individuals (12 males, 12 females) were
taken as samples
Ethnocentric
recruited within University College London
might have higher intelligence
white/London residents/UK locals
non generalisable to other culture/individuals
with differing IQs
students and staff as samples
external factors affected their response
THANK
