fNIRS cortical activation in Tai Chi observational learning.
Article in Frontiers in psychology, 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
Introduction: Observational learning plays a critical role in motor skill acquisition. Investigating the neural substrates involved in this process is of great significance for optimizing teaching methodologies and advancing brain-computer interface technologies. Methods: An experimental design combining functional near-infrared spectroscopy (fNIRS) and behavioral analysis was employed. The fNIRS protocol utilized a 2×3×2 factorial design. Results: Behavioral findings: The RSVD group (Regular-Speed Videos Demonstration) exhibited significantly higher movement accuracy scores compared to the SMVD group (Slow-Motion Video Demonstration). Cognitive load assessments revealed that the SMVD group experienced significantly higher cognitive load than the RSVD group. fNIRS findings: During the observational learning phase, significant activation increases were observed in the Frontal Eye Fields (FEF, BA8) and the Pre-Motor/Superior Motor Cortex (SMA/Pre-SMA, BA6) compared to the demonstration phase. The Frontopolar Cortex (FPC) showed reduced activation during the observational learning phase relative to the demonstration phase. In the Right Frontopolar Area (RFPC, BA10), activation was significantly greater in the simple task condition compared to moderate and difficult task conditions. Conclusion: In the early stages of instruction, SMVD may impede the effectiveness of observational learning for Tai Chi. Both the action demonstration and observational learning phases demand greater neural resources and broader brain network connectivity, requiring coordinated engagement of cognitive and motor systems.
