Overview

Saccades demonstrate reduced averaging with auditory cues, indicating better target discrimination accuracy.

Key Points

  • This study aims to investigate how auditory cues affect the accuracy of saccadic eye movements towards double targets.
  • Compared initial saccade amplitudes to single targets and pairs of targets.
  • Assessed the impact of auditory cues on target discrimination.
  • Varying target durations from 33 to 100 ms followed by a mask.
  • Auditory cues reduced saccadic averaging for target separations as small as 2°.
  • Saccadic averaging increased for targets shown briefly, indicating lower resolution.
  • Initial saccades often directed towards the midpoint between two targets.
