Document Summary
Gall who brought in concept of phrenology: areas for different functions. =prefrontal lobe = intellectual function = from people and primates; bulge in front = highly intelligent. Took group of monkeys trained them in series of behavioural tests looking at learning and memory/ higher order functioning and then did frontal lobotomy removing the prefrontal area (anterior portion of frontal lobe) Found that monkeys had loss of delayed response capabilities (could not perform, if there was a delay in time between seeing the solution and actual performing the solution) Put monkey in cage, good at tool usage. Thought this meant that general loss in immediate or short term memory. However found that if he left animals in dark during delayed period or given sedative (barbiturate) animals could actually solve and found that it was not memory it was distractability/ emotionality. Also found animals had problem in alternation (cups and rasisn)
