Flashcards in Biopsychology-lateralisation&split Brain Deck (8):
1

Lateralisation

The theory that the left and right hemispheres have specialist functions

2

Functions of the left hemisphere

Controls the right side of the body
Language
Right visual field

3

Right hemisphere functions

Controls the left side of the body
Spatial tasks
Left visual field
Facial recognition

4

Sperry

Group of severe epileptics who suffered seizures that couldn’t be controlled by drugs
Shown pictures to the left or right visual field, participants covered one eye and looked at a fixed point on a screen, slides projected on either the right or left side at high speed
If a pic was first shown in the left visual field participants didn’t recognise when it appeared in the right but if appeared in the right visual field patient could describe in speech and writing

5

Reductionist

Should consider that there are multiple functions in both hemispheres

6

Sample bias for sperry

Individual differences only 12 people who were used all had severe epilepsy so can’t generalise

7

Controlled assessments

Lab experiment, controlled artificial environment
Scientifically tested but lacks ecological validity

8

Plasticity (disadvantage )

Kitten study sewed the kittens eyes on, shows each hemisphere may not have specific function can adapt and change
Which contradicts laterlisation
