split-brain research

• Serving corpus callosum (mainly for epilepsy)

  Sperry

  • 11 participants with split-brain
  • image projected to RVF or LVF
  • Describing task: RH (LVF) couldn’t describe, LH could - LH language dominant
  • tactile task: both coudl select matching object (somatosensory area in middle)
  • drawing task: RH good drawing - visual dominant
  • composite task: RH draw hat they saw, LH describe what they saw - can’t communicate
• split-brain research - evaluations

  • S: split-brain better at certain tasks (odd one out) + LH better at cognitive strategies, watered down by weak RH
  • S: standardised procedure - replicable - internal validity
  • W: causal relationships: slip-brain compared to neurotypical - unique effects of split0brain a result of epilepsy
  • W: artificial task: real patients can se both hemispheres
