The __________ __________ refers to a bundle of nerve fibres that connect the two hemispheres of the brain.
(a)
The corpus callosum is a bundle of __________ __________
(a)
(a) is a condition whereby bursts of electrical activity in the brain cause seizures.
Patients with severe (a) have previously had their corpus callosum severed to separate the two hemispheres.
Patients with a history of severe epilepsy who had their corpus callosum severed have been referred to as __________ _________ patients
(a)
__________ __________ refers to the idea that certain functions are governed by one hemisphere of the brain.
(a)
Sperry conducted split brain research to investigate:
Localisation of function
Hemispheric lateralisation
Plasticity of the brain
Functional recovery of the brain after trauma
How many split-brain patients took part in Sperry's research?
(a)
In his 'recognition by touch' test, Sperry found that:
Split-brain patients could select by hand out-of-sight objects with their right hand when they were previously shown in their left visual field.
Split-brain patients could select by hand out-of-sight objects with their right hand when they were previously shown in their right visual field.
Each hemisphere processes information and controls movement on the same side of the body.
Each hemisphere processes information and controls movement on the opposite side of the body.
In his 'describe what you see' test, Sperry found that:
When a picture was presented to split-brain patients' right visual field, they could say what they saw.
When a picture was presented to split-brain patients' right visual field, they could not say what they saw.
When a picture was presented to split-brain patients' left visual field, they could not say what they saw.
When a picture was presented to split-brain patients' left visual field, they could say what they saw.
The left hemisphere specialises in language.
In his 'Matching faces' test, Sperry found that:
Split-brain patients matched faces shown in their left visual fields more quickly and more accurately.
Split-brain patients matched faces shown in their right visual fields more quickly and more accurately.
The right hemisphere is dominant for facial recognition.
The right hemisphere, not the left, recognises faces.
From his split-brain research, Sperry concluded that:
The left hemisphere specialises in language.
The right hemisphere specialises in language
The right hemisphere is dominant for facial recognition
the left hemisphere is dominant for facial recognition
A split visual field refers to:
When participants are asked to focus on a dot in the centre of a screen and images are briefly presented to either the left or right visual fields.
When participants are asked to close one eye and images are briefly presented to either the left or right visual fields.
Sperry's research is easy to replicate because he used s (a) procedures.
It is difficult to generalise the findings of Sperry's split brain research because:
There were individual differences in the extent to which split-brain patients had their corpus callosums severed.
A small sample size was used.
Standardised procedures were used.
The research was conducted in the 1960s.
The fact that split-brain patients also had epilepsy was:
An independent variable
A dependent variable
A confounding variable
What experimental design did Sperry use?
Independent groups design
Repeated measures design
Matched-pairs design
What type of experiment did Sperry conduct?
Laboratory
Field
Natural
Quasi
A split-brain patient is shown an image of a house in the left visual field. What would they NOT be able to do?
Say what they saw
Draw what they saw with their left hand
Draw what they saw with their right hand
According to hemispheric lateralisation, the right hemisphere specialises in:
Speech production and comprehension
Receiving touch sensations and controlling motor movements on the left side of the body
Processing visual information from the right visual field and auditory information from the right ear
Facial recognition
According to hemispheric lateralisation, the left hemisphere specialises in:
Speech production and comprehension
Receiving touch sensations and controlling motor movements on the left side of the body
Processing visual information from the right visual field and auditory information from the right ear
Facial recognition
The fusiform face area (a brain region responsible for processing faces) is larger in what hemisphere?
Right hemisphere
Left hemisphere
Prosopagnosia is a condition where there is an impaired ability to recognise faces. This is more common after damage to what hemisphere?
Left hemisphere
Right hemisphere
There are individual differences regarding hemispheric lateralisation. For example, the left-side lateralisation of language is less common in people who write with what hand?
Right hand
Left hand
Research has found that the brain becomes more lateralised in adulthood.
True
False
Turke observed a patient who, after suffering damage to Broca's area in the left hemisphere, developed the capacity to speak using a brain region in the right hemisphere. This -provides opposing evidence for:
Functional recovery of the brain after trauma
Hemispheric lateralisation
Localisation of function in the brain
