Relationship between feedback frequency and task performance: evidence on the mediating role of heart rate.
Article in Frontiers in psychology, 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
This study looks into the impact of feedback frequency, a source of cognitive load, on heart rate (HR) and heart rate variability (HRV). The experiment was undertaken using a sample of 96 university students, wherein the feedback frequency was manipulated during an arithmetic task performance. During the task, participants were instructed to wear the E4 Empatica device, which is used to assess HR and HRV. The metrics used to measure HRV were the Standard Deviation of NN Intervals (SDNN) and Root Mean Square of Successive Differences (RMSSD). The study revealed notable disparities in the average HR values across the three feedback conditions. Optimal performance was achieved when HR was elevated (indicating the highest level of cognitive load) and feedback frequency was moderate. Further, HR mediated the association between feedback frequency and task performance. However, no significant impact of feedback frequency on HRV was found.
