Temporal metacognition, the ability to evaluate one’s own timing performance, remains a relatively understudied aspect of self-monitoring. Recent findings from temporal reproduction tasks in both humans and rodents (Oztel & Balci, 2024) suggest that individuals can access information about the magnitude and direction of their timing errors, pointing to a capacity for metacognitive evaluation in the temporal domain. However, it remains unknown whether temporal metacognition is supported by shared mechanisms also contributing to other perceptual and cognitive tasks or whether it is highly specific to the time domain. This question builds on a broader debate in the metacognition literature: does metacognitive monitoring rely on domain-general or domain-specific mechanisms? Prior research has primarily addressed this by comparing metacognitive performance across sensory modalities or between domains such as perception and memory, yielding mixed evidence for both shared and distinct processes (Rouault et al., 2018). To extend this line of inquiry into the temporal domain, we adapted a confidence forced-choice paradigm (de Gardelle & Mamassian, 2014, 2016) to compare metacognitive judgments across a temporal and a visual bisection task. Participants performed pairs of trials and indicated which response they felt more confident about. Preliminary results show an increase in psychophysical sensitivity for trials selected as more confident, in both tasks. Moreover, participants were able to compare confidence across domains, suggesting the presence of a domain-general format for confidence. To investigate the underlying cerebral mechanisms, EEG recordings are being conducted in a second study. We hypothesize that temporal metacognition might involve domain-general readout mechanisms acting on task-specific network dynamics. This work aims to provide new insights into whether temporal metacognition is integrated within a unified self-monitoring system or operates independently from other domains.
