Behavioral intervention with task repetition compared to pharmacological intervention with SSRI for enhancement of cognitive control in emotional and non-emotional settings.
Trial report in Psychopharmacology, 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
rationaleCognitive control is crucial for optimal daily functioning and for emotional well-being. Cognitive control has been shown to be modified by experimental manipulations under widely differing experimental conditions, including cognitive training, and pharmacological intervention mainly probing catecholaminergic systems with little focus on the serotonergic system.
objectivesTo explore the role of serotonin on cognitive control in emotional and non-emotional settings.
methodsBehavioral, electrodermal and prefrontal activity measures were evaluated to compare the effects of single-session task repetition and single-dose serotonergic intervention with escitalopram on cognitive control in healthy participants, using cognitive and emotional Stroop tasks.
resultsFor cognitive Stroop, task repetition improved performance both 'on-line' within an ongoing task and 'off-line' after a four-hour delay, and escitalopram had no additional effects on this. In emotional Stroop, escitalopram enhanced the practice-related performance gain, starting from the second stimulus of each block. Compared to placebo, escitalopram also significantly reduced overall rate of premature responses. Regarding brain activation, escitalopram significantly reduced prefrontal activity during cognitive and even more so during emotional Stroop task. Lastly, electrodermal response showed significant habituation during cognitive but not emotional Stroop, in an effect that was not significantly modified by escitalopram.
conclusionsCognitive control in emotional and non-emotional settings may respond differently to behavioral and pharmacological manipulations. Escitalopram may selectively improve cognitive control in an emotional setting compared to cognitive control in non-emotional settings.
