Levels of orientation bias differ across digital content categories: Implications for visual perception

Area of Science:

• Visual perception
• Environmental psychology
• Digital media studies

Background:

• The oblique effect describes a bias towards horizontal and vertical lines over angled ones, potentially due to environmental exposure.
• Traditional 'carpentered' environments show more canonical than oblique contours, influencing visual processing.
• Increasing digital device use shifts visual experience towards digital environments, raising questions about their impact on orientation sensitivity.

Purpose of the Study:

• To investigate the potential influence of digital content on the oblique effect.
• To quantify orientation anisotropy in various digital and real-world scenes.
• To compare the orientation characteristics of digital media with natural and built environments.

Main Methods:

• Fourier analysis was employed to measure orientation anisotropy in digital scenes.
• Digital content (cartoons, video games, social media) was analyzed.
• Real-world scenes (nature, suburban, urban) served as a baseline for comparison.

Main Results:

• Digital content exhibits wide variation in orientation anisotropy.
• Pixelated video games and social communication websites showed significantly higher orientation anisotropy than all real-world scenes.
• This suggests digital environments may possess a stronger bias towards canonical contours.

Conclusions:

• Digital content, particularly certain video games and social media platforms, may induce a more pronounced oblique effect than previously observed.
• The pervasive nature of digital media could lead to substantial shifts in human visual orientation bias.
• Further research is needed to understand the full implications of these findings for visual processing and cognition.
