Mind-Craft: Exploring the Effect of Digital Visual Experience on Changes to Orientation Sensitivity in Visual Contour...

Area of Science:

• Visual perception
• Environmental statistics
• Human-computer interaction

Background:

• Visual perception relies on environmental statistical regularities.
• Natural scenes exhibit orientation anisotropy, favoring horizontal/vertical over oblique.
• This anisotropy contributes to the oblique effect, where canonical orientations are perceived more easily.

Purpose of the Study:

• To investigate if digital visual experience alters the oblique effect.
• To determine if exposure to framed digital content changes orientation anisotropy.

Main Methods:

• Developed a novel eye-tracking method to reliably measure the visual oblique effect.
• Experiment 1 validated the eye-tracking method and confirmed the oblique effect.
• Experiment 2 exposed participants to a video game and assessed changes in visual orientation perception.

Main Results:

• The developed eye-tracking method effectively indexed the visual oblique effect.
• A single session of video game exposure significantly altered visual orientation perception.
• Digital screen media's caricatured statistics can modify visual contour perception.

Conclusions:

• Digital visual experience, specifically with video games, can rapidly alter the oblique effect.
• Exposure to digital screen media's unique statistical properties impacts visual perception.
• This suggests that modern visual environments may be reshaping fundamental aspects of visual processing.
