Lateralisation and split brain-EVAL Flashcards
what is one issue with split brain research?
It is idiographic because it looks at INDIVIDUAL case studies such as Sperrys research and makes a GENERAL assumption about th erest of the population. This means it lacks POP. validity as we CANNOT generalise result sof one individual to the rest of the world.
Another issue of split-brain research is that it was NOT standardised.
This was because the severance of the corpus callosum was more severe on different degrees to some patients than others. This means that there will be a LACK of control in the study, making us unsure on the findings of the research.
another issue with split-brain research is that some patients were previously suffering from epilepsy
These patients were suffering from epilepsy and were on long-term drugs. This is an issue as it becomes a CONFOUNDING variable;e, affecting the results of the study and LOWERING the I.v as we’re not sure if we are measuring split-brain research or effects of drug therapy, or epilepsy.
One strength of split-brain research is that it uses case-studies.
This is a strength as it ALLOWS in DEPTH research on an individual.
HOWEVER, it may also be a weakness as similarly to split-brain’s Sperrys research ultimately becomes IDIOGRAPHIC when you attempt to generalise result so the rest of the population.
