Practice makes better? The influence of increased practice on task conflict in the Stroop task
Open accessAbstract
The Stroop task is widely used to study attentional control and cognitive flexibility. However, questions about its sensitivity to training and the impact of task conflict on attentional control remain open. We investigated the effects of practice and task conflict on attentional control in the Stroop task, with participants completing four sessions of a Stroop task over 3 weeks in low and high task-conflict conditions. Our results show that the level of task conflict had an impact only in the first session, even though participants remained sensitive to task conflict throughout all four sessions. Moreover, we found that practice reduced response times in the Stroop task, for both congruent and incongruent trials. Nevertheless, the interference between congruent and incongruent stimuli remained consistent over the 3-week period, indicating that inter-condition interference is not affected by training. Our study, therefore, suggests that the extent to which the level of task conflict modulates Stroop task performance is only partially sensitive to training. These findings provide further insights into the role of task conflict and practice in attentional control and cognitive flexibility.

The change in cognitive performances from pre to post-heating in this study exceeds the typical learning gains and known coefficients of variation (∼8%; 3-7%) for Stroop test reaction time and IGT net score respectively.
“However, based on practice gains reported in literature, the change in cognitive performances from pre to post-heating in our study exceeds the typical learning gains and known coefficients of variation (∼8 %; 3–7 %) for Stroop test reaction time and IGT net score respectively.54, 55, 56, 57”
From Influence of habitual physical activity on cognitive performance of healthy young adults after passive heat exposure (2026) · cites this paper as [54]
The Results (page unavailable) report that Stroop reaction times decreased across practice sessions, supporting the claim that practice can improve Stroop performance. The paper does not establish a typical 8% learning gain or coefficient of variation, and it does not address IGT net scores or the cited study’s pre- to post-heating change. (LLM, conf=0.85)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
