Evaluation: Localisation of Function in the Brain

Question 1

outline Petersons brain scan evidence for LOF

Answer 1

scanned brains during listening tasks (Wernickes) and reading tasks (Brocas) and found that these areas of the brain were active during.

Question 2

Outline Tulvings brain scan evidence for LOF

Answer 2

semantic and episodic memories are found in different parts of the brain

Question 3

Outline the neurological evidence for LOF from Doughertys OCD patients

Answer 3

when OCD patients underwent cingulotomy:
1/3 had successful operations
14% partial responses
Suggests that the behaviour and symptoms of mental health disorders are localised

Question 4

Outline the case study facts of Gage

Answer 4

25 yrold - had a pole go through his left cheek, behind his left eye and out of the top of his head - tsking the frontal lobe out
- he survived but his personality was different
(calm>aggressive)
Evidence for frontal lobe being responsible for regulating moods

Question 5

outline the strengths and limitations of Gages case study evidence

Answer 5

S: evidence for frontal lobes function
L: generalisability

Question 6

Outline Lashleys research against LOF

Answer 6

took between 10-50% of cortex from rats learning a maze and found that no area was in use more than another
this suggests the brain functions more holistically
