Lateralisation and split brain research

Question 1

What is Lateralisation

Answer 1

it refers to the idea that the two halves of the brain have functional specialisations e.g left dominant in speech and language and the right is dominant in visual motor tasks

These two hemispheres are connected by the corpus callosum where they can share information

Question 2

What is split brain research

Answer 2

• the corpus callosum is cut to prevent them sharing information

Sperry and Gazzaniga studied split brain patients

Participants asked to respond when stimuli was presented to one of the hemispheres

Concluded that left hemisphere is responsible for language because verbal no response to the right hemisphere

Question 3

Evaluation

Answer 3

(-) split brain patients are hard to find and use in research, can’t exactly harm people on purpose to test - typically research has SMALL sample
