Neuroticism, extraversion, and emotion sensitivity in a nonclinical young adult sample.
Article in PloS one, 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
introductionAccurate recognition of others' emotional facial expressions, referred to as emotion sensitivity (ES), is a central component of nonverbal communication. Previous research suggests that personality traits such as neuroticism and extraversion may shape nonverbal emotion decoding but findings have been mixed. The present study examined whether these traits predict performance on the Belmont Emotion Sensitivity Test (BEST), a task designed to measure subtle discrimination of anger, fear, and happiness while minimizing response bias.
methodA sample of 289 college students completed self-report measures of neuroticism and extraversion, as well as the Belmont Emotion Sensitivity Test (BEST), which assesses the ability to discriminate subtle differences in facial expressions of fear, anger, and happiness. Depression, anxiety, and stress levels were also measured.
resultsFemale participants reported higher levels of neuroticism (t = 4.39, p < .001; d = .59) and extraversion (t = 2.33, p = .02; d = .33) than male participants. Neuroticism severity was positively correlated with depression, anxiety, and stress. Extraversion was negatively correlated with depression, anxiety, and stress (range of rs = .55-.68, p < .001). Multiple regressions showed that neither neuroticism nor extraversion significantly predicted ES scores for any emotion category. DISCUSSION: Although women reported higher levels of neuroticism and extraversion, these traits did not predict performance on a validated emotion sensitivity task. These findings suggest that, in this nonclinical young adult sample, neuroticism and extraversion were not robust predictors of performance on this measure of emotion sensitivity. Implications are discussed for theories linking personality, psychopathology, and nonverbal emotion perception.
