Strategic Control of Oculomotor Reflexes

Question 1

What is volitial control?

Answer 1

Voluntary control

Question 2

What did Hood and Atkinson (1993) do?

Answer 2

Tested fixation reflexes of infants with overlap and offset trials, very reflexive

Question 3

Why are infants very reflexive?

Answer 3

Subcortical structures are fully developed at birth but cortical structures underdeveloped

Question 4

What is the anti-saccade test?

Answer 4

See stimulus in periphery and look the opposite way

Question 5

How does age effect the anti-saccade test?

Answer 5

Do better as you age as cortical structures develop so better at offsetting reflexes, when get old and brain starts to deteriorate get worse again

Question 6

What did Machado et al. (2004) do?

Answer 6

Looked at FEF lesions on anti-saccade test, did much worse as no cortical control over reflexes

Question 7

What happens to our brains as we get old?

Answer 7

Ventricles get bigger, temporal lobe atrophy, sulci get bigger and thinner white matter tracts
