Meeting another's gaze shortens subjective time by capturing attention

Area of Science:

• Cognitive psychology
• Social neuroscience
• Visual perception

Background:

• Direct gaze is a salient social signal influencing cognition and behavior.
• The underlying mechanism of direct gaze effects (attentional capture vs. arousal) is debated.
• Time estimation is proposed as a method to differentiate between attentional capture and arousal effects.

Purpose of the Study:

• To investigate whether direct gaze effects are due to attentional capture or arousal.
• To examine the role of stimulus dynamics and ecological validity in direct gaze perception.

Main Methods:

• Temporal bisection task with stimuli of varying durations (988–1479 ms).
• Participants classified stimulus duration under conditions of direct vs. averted gaze.
• Comparison of effects with dynamic, static, figurative, and nonfigurative stimuli.

Main Results:

• Direct gaze led to underestimation of stimulus duration, supporting attentional capture.
• This effect was contingent on dynamic stimuli simulating movement toward the observer.
• Underestimation occurred with faces, eye regions, and eye-like stimuli, but not static faces or nonfigurative stimuli.

Conclusions:

• Direct gaze effects are primarily driven by attentional capture, not increased arousal.
• The dynamic nature of stimuli is crucial for eliciting the time underestimation effect.
• Future research should prioritize ecologically valid stimuli in social attention studies.
