Studies 2 Flashcards
Dougherty
44 ocd patients who had undergone cingulotomy 30% successful response 14% partial response LOCALISATION
Petersen
Used brain scans to show how wernicke area in temporal was active during listening task and broca in frontal during reading task LOCALISATION
Buckner + petersen
Revealed that semantic and episodic memories reside in different parts of prefrontal cortex LOCALISATION
Lashley
Removed areas of cortex in rats who were learning route of maze. Found no area was more important and all were important. Higher cognitive processes aren’t localised but holistic LOCALISATION
Dick and themblay
2% of modern researchers think language is completely controlled by broca and wernicke areas.LOCALISATION
fink
pet scans to identify areas active in visual processing task. RH active when attending to global elements and LH when focusing on finer detail LATERALISATION
nielsen
analysed brain scans and found people did use certain hemispheres for certain tasks but no dominant side LATERALISATION
rogers
lateralised chickens could look for food whilst watching for predators LATERALISATION
phineas gage
pole through frontal lobe caused bad temperment showed it was responsible for mood LOCALISATION
draganski
chemistry students 3 months before and after final exams larger grey matter in parietal cortex and hippocampus
maguire
cab drivers larger grey matter in hippocampus responsible for visual spatial infomation development
gazzaniga
split ps actually perform better on some tasks eg. odd one out
sperry procedure
11 split brain ps who had corpus callosum severed tested projectibg images to LVF and RVF
sperry findings
if shown to RVF could describe it
if shown to LVF could match it with left hand
