Saccades, or eye movements, can distort perception, especially for low-contrast stimuli. This study shows that crowding effects during saccades depend on stimulus contrast, challenging previous findings.

Area of Science:

  • Visual perception
  • Neuroscience
  • Oculomotor research

Background:

  • Briefly flashed objects near saccades (rapid eye movements) are mislocalized.
  • Saccadic perceptual distortions interact with stimulus contrast.
  • Crowding, the inability to identify a target due to surrounding stimuli, is contrast-dependent.

Purpose of the Study:

  • To investigate the interaction between stimulus contrast, crowding, and pre-saccadic perception.
  • To determine how contrast influences crowding during saccades.

Main Methods:

  • Observers reported the orientation of a Gabor target, with or without flanking Gabors.
  • Tasks were performed during fixation or before a saccade.
  • Target and flanker contrasts were independently varied (high/low).

Main Results:

  • Crowding impaired performance in both fixation and saccade conditions.
  • Saccades reduced performance for low-contrast targets without flankers.
  • Impending saccades impaired performance with low-contrast flankers, but not high-contrast ones.
  • Crowding magnitude was affected by saccades only when target contrast was high and flanker contrast was low.

Conclusions:

  • Results support modulation of perisaccadic spatial localization by contrast and saccadic suppression.
  • Findings contradict previous reports of pre-saccadic crowding release.
