Recognition patterns of dynamic emotional facial expression stimuli.
Article in Perception, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study examined the emotion recognition patterns as a function of facial expression speed and intensity by using dynamic facial expression stimuli. Ninety-six university students participated in an emotion identification task, viewing computer-presented facial expressions depicting six basic emotions. Each emotion was morphed to vary across four intensity levels (20%, 40%, 60%, and 80%) and four facial expression speeds (250 ms, 500 ms, 750 ms, and 1,000 ms). A repeated-measures ANOVA was conducted to compare the effects of emotion, intensity, and facial expression speed on accuracy, false alarm rate, sensitivity, and response time. Significant two-way and three-way interactions were observed. Simple effects analyses revealed that each emotion demonstrated distinct optimal combinations of intensity and facial expression speed for accurate, sensitive, and fast recognition. Furthermore, recognition was optimized when expression speed matched intensity within each intensity level: low-intensity expressions were better recognized at faster speeds, while high-intensity expressions were better recognized at slower speeds. These findings suggest that emotion recognition varies systematically with specific combinations of facial expression speed and intensity, highlighting the importance of dynamic features in understanding facial emotion perception.
