Predictive remapping of visual features precedes saccadic eye movements.

Area of Science:

• Neuroscience
• Cognitive Psychology
• Visual Perception

Background:

• Saccadic eye movements are frequent, posing challenges for continuous visual perception.
• Understanding how visual information is integrated across fixations is crucial.

Purpose of the Study:

• To investigate how visual form processing is altered presaccadically.
• To determine if visual adaptation transfers across saccades.

Main Methods:

• Human observers prepared for saccadic eye movements to displaced or stationary stimuli.
• Visual form adaptation was measured at current and future fixation points.
• Perception of intermediate stimuli was assessed.

Main Results:

• Visual form adaptation transferred from the current fixation to the saccadic target location before the saccade.
• This presaccadic adaptation influenced perception of stimuli at intermediate locations.
• Adaptation transfer occurred even when preparing to move eyes toward a peripheral stimulus.

Conclusions:

• Visual processing is remapped presaccadically, involving a transfer of adaptation.
• This presaccadic remapping of visual processing may explain the perception of smooth visual transitions across glances.
