A-Level Psychology (AQA): Biopsychology - Hemispheric Lateralisation and Split Brain Research

[@amberfreeman342]

this is the first time ive understood sperrys research and my exam is tomorrow you saviour!!!

[@fionapowleychangecoach2858]

Ok... that makes so much more sense. Thank you for a really good visual and auditory explanation 👍🏼

[@smcartledge2723]

You're very welcome! Thanks for the comment.

[@saranajafi5952]

do we need to learn 3 evaluation points each for hemispheric lateralisation and split-brain research, or just three in total for that sub-topic?

[@Artfu1_d0dg3r]

Dude I finally understand sperry’s research thank you so much!!!!

[@TheManOfLaMancha]

taking a levels this year?

[@smcartledge2723]

You are very welcome.

[@smileyourebeautiful9613]

you’re amazing ! thank you so much :)

[@smcartledge2723]

Thank you very much

[@ellafaughnan4605]

When completing a 16 marker on this topic do we just evaluate the research or evaluate the theory as well? For example, Nielsen et al (2013) found no dominance when using hemispheres.

[@smcartledge2723]

You can evaluate both. Just make sure you are being clear on what you are evaluating.

[@ellafaughnan4605]

@@smcartledge2723 thank you very much! Your videos are super helpful.

Hi sir, can we get a 16 marker on hemispheric lateralisation and if we do then can we use ao3 points from localisation of function or split-brain research?

[@smcartledge2723]

Yes you can and If you do get a 16 marker on hemispheric lateralisation you can include split-brain research in your outline. So then you can use the AO3 points from both hemispheric lateralisation and split-brain research.

Is the horizontal row of lights not part of the procedure , where they flashed the patients right visual field and left VF, or is that the same procedure as the one as you have stated ?

[@smcartledge2723]

Sorry, what row of lights?

[@scarlettalexaaa]

very late reply but i think that was a sub experiment (it is listed on the simplypsychology website as the only one idk why) but the one with the words seems to be spoken about as the main experiment :)

[@umaraju593]

nicely explained. Thank you

[@scarlettalexaaa]

In an outline would we include all of the variations as in the saying words, drawing, composite words and the fruit one? or just focus on one or two in more depth?

[@smcartledge2723]

I would say two lots of findings would be plenty. Provided of course that the question isn’t specifically asking for more.

[@FILMSPECTIVEMAGAZINE]

hi sir, i'm quite confused on that if the corpus calusum is severed or destroyed how is both hemispheres still connected. on a normal person where corpus collosum is still intact is both hempishere conntect to one another

[@smcartledge2723]

If the corpus callosum is severed the two hemispheres cannot communicate. That is what was happening with the split brain patients. The two hemispheres were not communicating. E.g in a connected brain when the right hemisphere processes information it communicates it to the left so it can be said out loud. In a Split Brain Patient the communication can’t happen and so the information cannot be verbalised.
