AO3

• A strength is that there is a lot of evidence to suggest that functions are localised eg. Patient HM, FK, Clive Wearing, Patient Tan
• the case of Phineas Gage supports the localisation aspect of personality
• a strength is that extreme neurosurgical removals of parts of the brain have equally shown that some symptoms of mental disorders are localised
• a weakness is that lashley suggested that cognitive processes and learning are distributed holistically across various locations of the brain
• a weakness is that it is difficult to draw conclusions about localisation of personality from data
• a weakness is that it is hard to know if damage caused by an injury or disease was due to the location of the lesion or other factors such as age, gender, genetics etc.
