Hemispheric Lateralisation And Split Brain Research

Question 1

Hemispheric Lateralisation

Answer 1

The idea that the two halves of the brain are functionally different and are specialised

Question 2

What connects the two hemispheres of the brain

Answer 2

The corpus callosum

Question 3

What is the function of the corpus callosum

Answer 3

Interhemispheric communication

Question 4

What is the procedure called that removes the corpus callosum

Answer 4

Commissurotomy

Question 5

Who conducted a study into split brain research

Answer 5

Sperry and Gazzaniga

Question 6

What was the aim of Sperry and Gazzaniga’s research?

Answer 6

To examine the extent to which the two hemispheres are specialised for certain functions

Question 7

What were the four different types of tasks in Sperrys study

Answer 7

• describe what you see
• describe what you feel
• draw what you see

Question 8

What was the conclusion of Sperry and Gazzanigas study

Answer 8

There is differences between the two hemispheres, the left hemisphere is dominant in speech and language, and the right is dominant in terms of visual-motor tasks

Question 9

What is an assumed advantage of brain lateralisation

Answer 9

Increases processing capacity and the ability to perform multiple tasks simultaneously

Question 10

What research supports the advantages of lateralisation

Answer 10

Rogers - found in a domestic chicken that hemispheric lateralisation caused them to be able to search for food and also be vigilant for predators at the same time
