The theory that different areas of the brain are responsible for different behaviours/processes/activities.
1 of 14
What is hemispheric lateralisation?
The idea that 2 halves (hemispheres) of the brain are functionally different. Certain mental processes/behaviours are mainly controlled by one hemisphere rather than the other, eg. language = left hemisphere.

What's the motor area?
A region at the back of the frontal love, involved in regulating movement
3 of 14
WHat's the somatosensory area?
An area of the parietal lobe that processes sensory information such as touch
4 of 14
What's the visual area?
A part of the occipital lobe that receives and processes visual information
5 of 14
What's the auditory area?
Located in the temporal love and concerned with the analysis of speech based information
6 of 14
What's Broca's area?
An area of the frontal lobe in the left hemisphere (in most people), responsible for speech production
7 of 14
What's Wernicke's area?
An area of the temporal lobe (encircling the auditory area) in the left hemisphere (in most people) responsible for language comprehension

Frontal, Parietal, Occipital, Temporal, Cerebellum and the Spinal chord

Evaluation - Brain scan evidence of localisation +
Evidence suggests many neurological functions are localised. Tulving et al revealed that semantic and episodic memories reside in different parts of the frontal cortex.
10 of 14
Evaluation - Neurosurgical evidence +
The practice of surgically removing or destroying areas of the brain to control aspects of behaviour developed in the 1950s
11 of 14
Evaluation - Case study evidence +
Unique case studies of neurological damage support the localisation theory such as Phineas Gage

Evaluation - Lashley's research -
Learning isn't localised but distributed in a more holistic way.Learning is too complex to be localised and requires the involvement of the whole brain
13 of 14
Evaluation - Plasticity -
Argument against localisation - cortical remapping law of equipotentiality, where surviving brain circuits 'chip in' so the same neurologcal action can be achieved
