Localisation Of Function Flashcards
(15 cards)
What is the theory of localisation of function
Different areas of the brain are responsible for different functions in behaviors
What is the cerebral cortex and what are the 4 parts
Outer part of the brain
Frontal lobe
Parietal love
Occipital love
Temporal lobe
What is the frontal lobe responsible for
- movement, personality and higher level thinking (e.g. problem solving)
- motor area at back of frontal lobe responsible for controlling movements
What is the parietal love responsible for
- processing information from our senses
- somatosensory area - primary sensory area
What divides the frontal and parietal lobe
Central sulcus
What is the occipital lobe responsible for
- visual area
- receiving and processing visual information
What is the temporal lobe responsible for
- auditory area
- analysis of speech related information
What is aphasia
Term given to someone who has lost ability to understand or produce speech
What is Broca’s Area/Aphasia
Broca’s area - left frontal lobe, speech production
Broca’s aphasia - impaired ability to produce language caused by damage to Broca’s area
What was Broca’s research?
1861 - Patient Tan who always answered Tan Tan to questions and post mortem revealed her had lesion in the left frontal lobe
Wernicke’s Area and Aphasia?
Wernicke’s Area - left frontal lobe - speech comprehension
Wernicke’s Aphasia - impaired ability to understand speech caused by damaged Wernicke’s Area
AO3 Strength point
Wealth of case studies from patients with brain damage that helped develop our understanding
AO3 Strength evidence
For example, HM who had his hippocampi removed following epileptic seizures was no longer able to transfer episodic and semantic memories from STM to LTM but could learn new procedural tasks like the mirror drawing task
AO3 Limitation point
Failure to consider individual differences
AO3 Limitation evidence
Harasty (1997) found women have proportionally larger Broca’s and Wernicke’s Area explaining women’s greater ease with language. Beta bias as theory overlooks gender differences in men and women of brain regions size and activity
