Brain Lateralisation

Question 1

What is Brain Lateralisation

Answer 1

Theory suggest both hemispheres function differently. Certain process are controlled by either the right or left hemisphere.

Question 2

What is the role of the Corpus Callosum

Answer 2

Some task require communication between both hemispheres. This means info is sent through the corpus callosum which allows the two hemispheres to communicate.

Question 3

What is the role of the left hemisphere?

Answer 3

Include language task E.g reading & speech

Question 4

What is the role of the right hemisphere?

Answer 4

Tasks on the right include spatial abilities E.g touch and drawing

Question 5

What was the aim of sperry (1968) split brain research

Answer 5

To investigate the role of each hemisphere in split brain patients (Corpus Callosum has been cut)

Question 6

What was the procedure sperry (1968) Split Brain Research

Answer 6

Participants eyes were fixed on centre of screen. Presented visual stimuli either on left or right of screen, participants had to identify or describe what they saw revealing how each hemisphere functioned.

Question 7

Findings of sperry (1968) Split Brain research

Answer 7

When right eye saw a word, left hemisphere could name it. When left eye saw a word to the right hemisphere visualises it, but speaking left couldn’t name it. Shows Corpus Callosum is essential for dual tasks.
