case studies and patient HM
positive evaluation points
- avoids ethical issues of invasive investigation
- credibile - ultilises neuroimaging techniques (objective data)
- concurrent validity - collects large amount of data with several techniques
case studies and patient HM
negative evaluation points
- cause and effect - only study patient after damage - don’t know what he was like before
- low validity - neuroimaging may not pick up smaller sites of damage - e.g. mild traumatic brain injury
- population validity - unique cases - might not be generaisable to other brain damaged patients
