Trace: A research media player measuring real-time audience engagement.
Article in Behavior research methods, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Measuring attention and engagement is essential for understanding a wide range of psychological phenomena. Advances in technology have made it possible to measure real-time attention to naturalistic stimuli, providing ecologically valid insight into temporal dynamics. We developed a research protocol called Trace, which records anonymous facial landmarks, expressions, and patterns of movement associated with engagement in screen-based media. Trace runs in a standard internet browser and resembles a contemporary media player. It is embedded in the open-source package PsychoJS (the JavaScript sister library of PsychoPy) hosted via Pavlovia, and can be integrated with a wide range of behavioral research methods. Developed over multiple iterations and tested with over 200 participants in three studies, including the official broadcast of a major theatre production, Trace is a powerful, user-friendly protocol allowing behavioral researchers to capture audience attention and engagement in screen-based media as part of authentic, ecologically valid audience experiences.
