Larger visual changes compress time: The inverted effect of asemantic visual features on interval time perception.

Area of Science:

• Cognitive psychology
• Visual neuroscience
• Human-computer interaction

Background:

• Time perception is influenced by visual input, with low-level features affecting millisecond judgments.
• High-level cognitive and semantic factors influence time perception at longer intervals (seconds to minutes).
• Previous studies often confound semantic content with visual properties, complicating analysis of purely visual effects.

Purpose of the Study:

• To investigate the impact of as-semantic visual properties on interval time perception.
• To isolate the effects of visual features devoid of emotional or semantic meaning.
• To understand how visual manipulations influence perceived duration in seconds and minutes.

Main Methods:

• Experiments utilized binary and production tasks.
• Studies were conducted using both conventional and head-mounted displays.
• Four visual features were manipulated: spatial luminance contrast, temporal frequency, field of view, and visual complexity.

Main Results:

• A consistent pattern emerged: increased visual changes shortened perceived time.
• This effect was observed for time intervals up to 3 minutes.
• Findings contrast with previous research showing visual changes affecting millisecond-level time perception.

Conclusions:

• As-semantic visual properties significantly influence interval time perception.
• Larger visual changes lead to a compression of perceived time.
• These findings have potential applications for altering time perception in real-world scenarios.
