Background:

Temporal visual attention in dynamic content is less studied than spatial attention.
Existing methods for temporal salience rely on gaze or content analysis.
Understanding temporal attention is crucial for video processing and user engagement monitoring.

Purpose of the Study:

To investigate the potential of using only brain signals to reveal temporal visual attention.
To develop methods for computing temporal visual salience and temporal brain salience.
To assess the correlation between visual and brain-derived temporal salience scores.

Main Methods:

Computed temporal visual salience from video frame salience maps.
Quantified temporal brain salience using cognitive consistency scores from multi-observer EEG data.
Assessed correlations between visual and brain salience scores using DEAP and MAHNOB datasets.

Main Results:

Found significant correlations between temporal visual attention and EEG-based inter-subject consistency.
Effect sizes (Cohen's d) ranged from small to very large across datasets.
Demonstrated that brain consistency among observers can unveil temporal visual attention cues.

Conclusions:

Brain signals, specifically EEG, can effectively reveal temporal visual attention.
This approach offers a novel, brain-signal-based method for analyzing attention in dynamic content.
Findings have implications for visual design, medical applications, and brain-computer interfaces.
