Cortical emotional reactivity, caregiver-reported emotional control, and stuttering frequency in young children.
Article in Journal of fluency disorders, 2025. 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
purposeThe present study aimed to determine whether cortical associates of emotional reactivity and caregiver-reported emotional control skills are associated with stuttered speech in young children who do (CWS) and do not stutter (CWNS).
methodTwenty young CWS and 24 young CWNS passively viewed neutral and affective pictures while their event-related potentials (ERPs) were recorded. Children's speech fluency was assessed during a free-play conversational speech sample before the ERP task. Participants' caregivers completed the Behavior Rating Inventory of Executive Function (BRIEF).
resultsFor CWS and CWNS, greater cortical reactivity to unpleasant pictures was associated with higher stuttering frequency. Parents of CWS rated their children poorer on the Emotional Control dimension of the BRIEF than parents of CWNS. However, the between-group difference on Emotional Control was no longer significant when group differences in expressive language scores were taken into account. Within-group analyses revealed that poorer Emotional Control scores were associated with higher stuttering frequency for CWS. Lastly, for CWS, poorer Emotional Control scores on BRIEF were associated with greater cortical reactivity to unpleasant pictures.
conclusionsOverall, findings replicate those of previous studies that reported a significant association between stuttering and emotion-related behavioral and physiological measures. Further, this study extends past work and provides the first evidence that cortical measures of emotional reactivity are associated with stuttering frequency. Potential mechanisms that may explain the nature of the association between emotional processes and stuttering frequency are discussed but must await further study to be elucidated.
