Semantic Modulation of Spatial Judgments in Augmented Reality: Evidence from fNIRS.
Article in Brain topography, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 examined how different types of semantic relationships modulate cortical activity during spatial judgments in an augmented reality (AR) setting. Participants viewed triads of everyday objects that were either thematically (co-occurring) or functionally (sharing a purpose) related and made spatial judgments varying in reference frame, egocentric (object closest to you?) vs. allocentric (object closest to another? ), and relation type, coordinate (distance-based) vs.categorical (left-right). Cortical activity was measured using functional near-infrared spectroscopy (fNIRS). Results showed that semantic modulation was most evident during allocentric-coordinate judgments, with increased activation in temporal regions for thematic triads compared to functional ones. In general, functionally related triads engaged parietal regions more broadly across conditions, while egocentric judgments elicited widespread parietal activity with reduced semantic modulation. Finally, categorical judgments showed minimal differences between semantic conditions. By combining AR with fNIRS, this study provides evidence that semantic knowledge influences cortical recruitment during spatial processing, offering a novel window into how meaning and spatial representation interact.
