❌- made up of the brain and spinal cord. The spinal cord is responsible for reflex actions, while the brain is the centre of all conscious awareness. It has a very advanced cerebral cortex compared to animals.
❌- made up of millions of neurons that transmit messages to and from the CNS.
❌- a subsystem of the PNS, this nervous system controls bodily functions, like breathing and heart rate
❌- a subsystem of the PNS, this nervous system controls voluntary movement.
❌- a branch of the ANS which is involved in the fight or flight response, and makes the body physiologically aroused
❌- a branch of the ANS which is involved in the fight or flight response, and returns the body to its resting state.

❌: the auditory area in which speech-based information is analysed. It is also in charge of facial recognition. Damage leads to partial hearing loss
❌: controls understanding speech. Damage leads to Wernicke's aphasia (fluent but nonsensical speech)

Explanation

Question 16 of 67

1

Select from the dropdown lists to complete the text.

There are three types of evidence which support localisation of function:

Brain scan evidence: ( Peterson, Wernicke, Tulving, Baddeley ) did brain scans and found Wernicke's area was active during listening tasks (understanding speech), while Broca's area was active for reading aloud tasks (speech production). ( Tulving, Peterson, Wernicke, Baddeley ) found that episodic and semantic memories were stored on different sides of the pre-frontal lobe. This type of evidence is scientific and objective.
Neurosurgical evidence: ( Dougherty, Baddeley, Tulving, Wernicke ) suggested that lesioning the cingulate gyrus helps treat OCD
Case study evidence: ( Phineas Gage, Clive Wearing, KF, Little Albert ) had a pole through his head which damaged the frontal lobe, and he became rash and lacked restraint. This shows the function of the frontal lobe

Explanation

Question 17 of 67

1

There are two main disadvantages of the localisation of function theory:
❌'s research: he removed parts of the cortex in rats and found that it didn't matter which part was removed, the effect on learning was the same. This supports the holistic view.
❌: when damaged, the brain can reorganise itself to recover the lost function. This suggests that all parts of the brain are involved in functions, thus supporting the holistic theory.

Select one or more of the following:

Good supporting evidence- his research produced impressive and sizeable evidence for hemispheric lateralisation
Good supporting evidence- his research produced impressive and sizeable evidence for functional recovery
Good methodology- used specialised and standardised procedures

Name two disadvantages of Sperry's split-brain research

Select one or more of the following:

Insufficient evidence- there is very little evidence to support Sperry's theory
Poor methodology- lack of standardisation and control, with researcher bias playing a significant role in the findings

1

What is one disadvantage of Campbell and Murphy's study into exogenous zeitgebers (shining light pads on the back of knees)?

Select one of the following:

May have had partial exposure to light in their eyes
The influence of demand characteristics was ignored
All participants had had the backs of their knees checked for sensitivity beforehand, so may not be able to generalise to the wider population

Explanation
