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
