Hemespheric Lateralisation

Question 1

What is hemispheric lateralisation

Answer 1

Refers to the fact that some mental processes in the brain are mainly specialised to either the left of right hemisphere

Question 2

Which sides of the body does each hemisphere control

Answer 2

Left hemisphere- right side of the body
Right hemisphere- left side of the body

Question 3

Which functions is the left hemisphere responsible for

Answer 3

Language, movement of right side of body and processes information from right visual field

Question 4

Which functions is the right hemisphere responsible for

Answer 4

Visual-motor tasks, movement of left sude of body and processes information from left visual field

Question 5

What is the corpus callosum

Answer 5

A bundle of nerve fibres which join the two hemispheres of the brain

Question 6

What is split-brain research

Answer 6

Research that studies individuals who have been subjected to the surgical separation of the two hemispheres of the brain as a result of serving the corpus callosum

Question 7

Name a split-brain study

Answer 7

Speedy and Gazzaniga (1967)

Question 8

And object is placed in the left hand and the patient is asked to name it- predict what would happen and explain why

Answer 8

The patient will not be able to name it because object will be processed by right hemisphere, but language is in left hemisphere

Question 9

An object is placed in the left hand and the patient is asked to find the object with the right hand- predict what will happen and explain why

Answer 9

They will not be able to find the object because the object will be processed by the right hemisphere, which controls the left hand, not the right

Question 10

What is a strength of this research

Answer 10

High internal validity: made use of highly specialised and standardised procedures= high degree of control over variables
