6. In which situation would a mobile eye tracking system be easier?
When exercising
During sleep
Studying social behaviour
In a lab
7. What percentage of errors to healthy controls make in the anti-saccade task?
41%
24%
10%
30%
8. In Gaymard et al. (1999), a patient with a lesion to the FEF had normal error rates in the anti-saccade task but increased time to make correct antisaccades. What does this suggest that the FEF is involved in?
Voluntary generation of saccades
Inhibiting unwanted reflexive saccades
9. What do the receptive fields in the lateral layers of the superior colliculus respond to?
Multisensory and motor neurons
Visual stimuli at specific locations
Electrical stimulation
Movements of external stimuli
10. What is saccadic suppression?
More visual processing occurs during saccades
The amount of saccades is increased
Little visual processing occurs during saccades
The amount of saccades is reduced
11. What does the anti-saccade task study?
Cortical control, reflexive and voluntary saccades
Cognitive inhibition, reflexive and voluntary saccades
Attention selection, cognitive inhibition and reflexive saccades
Attentional selection, reflexive and voluntary saccades
12. There can be activation in some neurons in the superior colliculus when... (Wurtz et al.)
Produce a saccade voluntarily
Covertly attending to a stimulus
Orienting reflexively towards sudden stimuli
Overtly attending to a stimulus
13. What is the aim of the anti-saccade task?
Attend to everything but the target
Look at the target
Look in the opposite direction of the target
Try to identify the target
14. What is the superior colliculus involved in?
Reflexive orienting towards sudden stimuli
Attending to the area in the visual field
Voluntary generation of saccades
Inhibiting unwanted reflexive saccades
15. What is vergence?
Eyes move in a different direction
Smooth tracking of target objects
Both eyes on a target which changes in depth
Eyes move in the same direction
16. Which of the structures discussed does not produce saccades when electrically stimulated?
FEF
DLPFC
SC
MC
17. What is drift?
Change on the fovea where the image is forming
Stationary period between saccades
Tiny fast movements
Smooth tracking of target objects
18. Electrical stimulation of neurons in the superior colliculus causes saccades with... (Wurtz et al.)
Orientation to sudden stimuli
A particular movement field
A preference for a particular location
19. What do the intermediate layers of the superior colliculus contain?
Multisensory and motor neurons
Multisensory and interneurons
Motor and mirror neurons
Receptive fields
20. How is a patient with a lesion to the FEF likely to perform on the anti-saccade task?
Normal error rates but increased time to make correct antisaccades
Abnormal error rates but decreased time to make correct antisaccades
Normal error rates and decreased time to make correct antisaccades saccades
Abnormal error rates and increased time to make correct antisaccades
