Spontaneous Ocular Scanning of Visual Symmetry Is Similar During Classification and Evaluation Tasks

Area of Science:

• Cognitive psychology
• Neuroscience
• Visual perception

Background:

• Symmetry perception and preference are well-researched.
• Mechanisms of spontaneous eye movements during symmetry observation are less understood.

Purpose of the Study:

• To investigate spontaneous saccadic eye movements when observing symmetrical patterns.
• To understand how eye movements relate to symmetry perception and evaluation.

Main Methods:

• Twenty participants observed patterns with horizontal or vertical mirror reflection.
• Saccadic eye movements were recorded during objective and subjective tasks.

Main Results:

• Participants predominantly made saccades along the axis of reflection.
• This eye-movement pattern was consistent across different task types.
• Axis-scanning generates dynamic visual sequences, potentially aiding symmetry processing.

Conclusions:

• Spontaneous eye movements follow the axis of symmetry.
• This oculomotor behavior may enhance visual symmetry perception and evaluation by increasing neural responses.
