Research on the influence of MW on situation awareness in shearer monitoring tasks in intelligent coal mines.
Article in Experimental brain research, 2026. 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
The study examined the impact of mind wandering (MW) on situation awareness (SA) under varying task difficulties and pinpointed the sensitive SA indicators. 43 participants completed the shearer status monitoring task under simple and complex tasks. It collected operational performance, SAGAT, SART, eye movements, and EEG data, followed by linear mixed models analysis. The results showed that: (1) During the simple task, MW with meta-awareness led to higher performance and SA compared to MW without meta-awareness. In the complex task, SA of MW without meta-awareness surpassed that of MW with meta-awareness. (2) MW without meta-awareness exhibited longer average fixation durations in the simple task. Furthermore, MW with meta-awareness showed inferior β1 and β2 absolute powers in the complex task. (3) β1 and β2 relative power, β2 absolute power, θ/β1, and θ/β2 weakly correlated with SAGAT in MW with meta-awareness, suggesting potential as sensitive SA indicators. SA moderately negatively correlates with fixation intensity. Conversely, δ and θ relative power, β1 and β2 relative power, β2 absolute power, θ/α1, θ/α2, θ/β1, and θ/β2 weakly correlated with SART in MW without meta-awareness, indicating potential as sensitive SA indicators. Moreover, fixation frequency may be linked to brain alertness levels. (4) As task difficulty increased, performance and SA decreased, whereas eye movement data increased. The research reveals the internal relationship between subconscious MW and SA under different task difficulties, and identifies a series of potentially sensitive physiological indicators. It provides a new perspective and empirical basis for further exploring the impact of MW on SA. The research findings can offer certain references for the optimization of operator training content and the design of information requirements for monitoring interfaces.
