Split Brain Research AO1

• Sperry's research


  • Researched with epileptic patients
  • Used Sperry box to present info to one visual field and ask to complete tasks
• Corpus callosum severed


  1. Picture presented to RVF - participants could describe (LANGUAGE=LH), and could select matching object with right hand

  2. If presented to LVF, they couldn't describe it but could select matching object with left hand

  3. Drawing better with left hand (even if right handed)

  4. Right hemisphere dominant for VISUAL MOTOR TASKS
• Sperry's research showed that with the corpus callosum severed, the two hemispheres cannot communicate
• Sperry's research used the Sperry box to present information to one visual field and ask participants to complete tasks
• When the picture was presented to the RVF, participants could describe it (as language is in the LH) and select the matching object with their right hand
• When the picture was presented to the LVF, participants couldn't describe it but could select the matching object with their left hand
• Participants drew better with their left hand, even if they were right-handed, showing the right hemisphere's dominance for visual-motor tasks
