Threat context impairs cognitive control of neutral words processing in social anxiety individuals: evidence from ERP and theta oscillations.

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
backgroundSocial anxiety (SA) is characterized by cognitive control impairments, particularly in the processing of threat, yet how threat-laden environments modulate cognitive control over neutral stimuli remains unclear. This study examined whether threat context impairs the processing of neutral words in individuals with high social anxiety (HSA) through electrophysiological and oscillatory dynamics.
methodsA total of 151 participants (HSA vs. low social anxiety, LSA) completed a Stroop task in two conditions: (1) threat context (neutral words intermixed with social threat words), and (2) neutral-only (neutral words only). Behavioral responses (RTs), ERP (N2, N450, SP), and frontal-midline theta oscillations were analyzed.
resultsThreat context significantly prolonged RTs in HSA compared to LSA individuals. ERP data revealed that LSA individuals exhibited larger N450 and reduced SP under threat than under neutral-only conditions, indicating efficient conflict resolution. However, LSA individuals showed blunted N450 but amplified SP, suggesting prolonged attentional engagement with neutral stimuli in threat contexts. Time-frequency analyses further demonstrated that LSA participants increased frontal theta power in the threat context, whereas HSA individuals displayed suppressed theta activity, reflecting impaired top-down cognitive control. Threat contexts contaminate the processing of neutral stimuli in HSA individuals, marked by attenuated conflict detection (N450), increased attention engagement (SP), and deficient theta-mediated control.
conclusionThese findings indicate that threat context impairs cognitive control of neutral word processing in HSA individuals when threat is possible, bridging cognitive and clinical models of attentional dysregulation. CLINICAL TRIAL NUMBER: Not applicable.
