Intertemporal meditation regulates time perception and emotions: an exploratory fNIRS study.
Article in Social cognitive and affective neuroscience, 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
Mental time travel enables humans to project life episodes into the future, shaping present behaviour through episodic future thinking. This study explored the effects of repeated mental time travel from the present to the end of life on the time perception and emotional experiences of young adults. Unlike previous studies that focused solely on a single moment (present or death), we introduced intertemporal meditation, which combines mindfulness meditation and episodic future thinking. Using a within-subject design combined with fNIRS recording, we compared pre-meditation with post-meditation measures in both mindfulness and intertemporal meditation conditions. Behavioural results showed that intertemporal meditation shortened time perception and made the participants feel more peaceful and less anxious. The fNIRS results revealed that intertemporal meditation resulted in higher overall brain activations than mindfulness meditation. Hemodynamic measures revealed significant left-lateralized activations in brain regions associated with emotion regulation and cognitive control, particularly the dorsolateral prefrontal cortex, anterior prefrontal cortex, and orbitofrontal cortex. In addition, right-lateralized activations in Broca's area and middle temporal gyrus indicated enhanced processing of social cues and autobiographical memory processing. These findings underscore the adaptive utility of intertemporal meditation in emotion regulation and its potential to improve cognitive control functions.
