the idea the certain functions of the brain belong to certain areas in the brain
Phineas Gage?
1848- iron pole went into head destroying the frontal lobe> change in personality . more angry and disinhibited > frontal lobe responsible for personality
Hemispheric lateralisation?
idea that 2 halves of the brain are responsible for different functions. 2 halves connected by nerve fibres the corpus callosum. (allows for communication
Equipotentiality theory?
basic motor and sensory functions are localised, but higher mental functions are not. claims that intact areas can take responsibility for specific cognitive functions
Petersen et al?
used brain scans to show that wernickes area was active when listening and brocas when reading.
Tulving et al?
semantic and episodic memories in separate parts of the brain
Lashley research?
removed 10-15% of rats cortex learning a maze, no area was more important. cannot generalise to humans.
Dronkers et al (2007)??
MRI scan found that other factors could be responsible for Tan speech production failure. such as damage to other areas.
Dejerne?
patient lost ability to read following damage to visual cortex and Wernicke's area. suggests damage to different areas can cause problems.
localisation?
biologically reductionist - some critics suggest that a more interactionist approach needed (cognitive and biological)
Herasty (1997)?
women have proportionally larger Broca's and Wernicke's area than men, which explains women greater ease of language. suggest beta bias in theory.
