3- Hemispheric Approach

Question 1

What does the hemispheric approach explore?

Answer 1

Hemispheric asymmetries in colour categorical perception

Question 2

How is the brain organised?

Answer 2

Contralaterally- visual projections from the right visual field are processed in the left hemispheres

Question 3

Where in the brain is language processed?

Answer 3

Left hemisphere

Question 4

How can the hemisphere approach see if language is involved in categorical perception?

Answer 4

If it is the CP is expected to be greater for stimuli in the right visual field

Question 5

Gilbert et al’s (2006) study

Answer 5

Asked people to find a colour on a colour wheel and they had to press a button to say whether a colour is different or not

Question 6

Gilbert et al’s (2006) findings

Answer 6

CP only when different colour was presented on right visual field

CP regardless of which visual field stimuli presented to

Question 7

What did verbal interference in Gilbert et al’s (2006) study create?

Answer 7

No CP in RVF anymore, but lots of CP in LVF

Question 8

Franklin et al’s (2008) study

Answer 8

Looked at eye movements comparing adults and infants, measured speed of fixation on colour

Question 9

Franklin et al’s (2008) stimuli

Answer 9

Coloured background and within or between categories coloured circle presented to the left or right visual field

Question 10

Franklin et al’s (2008) findings when presented to left hemisphere

Answer 10

Faster for right visual field and between-category trials

Question 11

Franklin et al’s (2008) findings when presented to right hemisphere

Answer 11

Faster for the left visual field and between-category trials

Question 12

Franklin et al’s (2008) findings in adults

Answer 12

Larger categorical effect for RVF

Question 13

Franklin et al’s (2008) findings in infants

Answer 13

Opposite effect to adults, RH bias when toddlers are learning colour terms and LH bias when toddlers have already learnt colour terms

Question 14

Maier and Abdel Rahman’s (2019) study

Answer 14

Presented 3 different categories of items and looked at length of time for people to realise there was a different category item

Question 15

Maier and Abdel Rahman’s (2019) findings

Answer 15

Categorical perception in the LVF, right side of the brain involved more in categorisation than left side
