Q

Right hemisphere

A

Emotion/creativity

17
Q

Contralateral

A

Hemisphere controls opposite side of body (LH -> right [e.g. motor])

18
Q

Ipsilateral

A

Hemisphere controls same side of body (LH -> left)

19
Q

Special case: vision

A

Both eyes have a left & right field of vision -> RVF = LH, LVF = RH

20
Q

Split-brain research

A

Severed connection between the LH & RH -> researchers look at how the hemispheres function w/o communication (surgery is done to reduce epilepsy)

21
Q

Study: Sperry

A
  • Aim: how 2 separated hemispheres deal with vision/speech related things
    + Sample: 11 people who had the operation
  • Method: Images projected to either LVF and/or RVF in 1/10th a second [they had 1 eye covered]
22
Q

Sperry’s findings (LVF)

A

Could not name what they had seen [no language in RH], could draw what they had seen with their left hand [controlled by RH], pinup girl scenario: had emotional reaction [blushing] but could not describe what had been seen

23
Q

Sperry’s findings (RVF)

A

Able to describe in speech & writing with right hand

24
Q

Conclusion of Sperry

A

LH = verbal
RH = silent but emotional

25
Q

+ Research on lateralisation

A
26

  • Research on lateralisation
