AO3: Localisation of function

    Cards (4)

    • Strength: Evidence from neurosurgery
      What? Damage to areas of brain linked to mental disorders
      Who? Dougherty et al. - 44 people w/ OCD; undergone cingulotomy - 30% had successful response, 14% partial response
      Why? Behaviours associated with serious mental disorders may be localised
    • Strength: Evidence from brain scans
      What? Evidence of localisation from brain scans
      Who? Peterson et al. - Broca's/Wernicke's area was active during reading and listening tasks respectively + Buckner and Peterson - semantic/episodic memories in different parts of prefrontal cortex
      Why? Sound scientific evidence
    • Limitation: Language localisation questioned
      What? Language mightn't be localised to just Broca's and Wernicke's areas
      Who? Dick and Tremblay - 2% of modern researchers think language controlled by Broca's and Wernicke's area - brain imaging shows language function is distributed holistically
      Why? Language may be holistic
    • Counterpoint: Evidence from brain scans
      What? Challenges localisation theory
      Who? Lashley - removed 10%-50% of rats' cortex - learning unaffected
      Why? Higher cognitive processes more holistic
