Sensorimotor conflicts alter perceptual and action monitoring

Abstract

142)1 Bodily self-consciousness is defined as a set of prereflective representations of integrated bodily 2 signals giving rise to self-identification, self-location and first-person perspective. While bodily self-3 consciousness is known to modulate perception, little is known about its influence on higher-level 4 cognitive processes. Here, we manipulated bodily self-consciousness by applying sensorimotor 5 conflicts while participants performed a perceptual task followed by confidence judgments. Results 6 showed that sensorimotor conflicts altered perceptual monitoring by decreasing metacognitive 7 performance. In a second experiment, we replicated this finding and extended our results by showing 8 that sensorimotor conflicts also altered action monitoring, as measured implicitly through intentional 9 binding. In a third experiment, we showed that effects on perceptual monitoring were induced 10 specifically by sensorimotor conflicts related to the trunk and not to the hand. Taken together, our 11 results suggest that bodily self-consciousness may serve as a scaffold for perceptual and action 12 monitoring.

Perceptual decision confidence is sensitive to forgone physical effort expenditure

“…This study sits within a growing body of literature which shows associations between action-related information and metacognitive judgements (Faivre et al, 2018(Faivre et al, , 2020Fleming et al, 2015;Palser et al, 2018;Pereira et al, 2020;Siedlecka, Hobot, et al, 2019;Siedlecka et al, 2020;Wokke et al, 2020). By directly manipulating the amount of effort required to report a decision we have shown that confidence depends, in part, on fine-grained representations of one's own actions.…”

“…Consistent with this view, a number of studies have provided evidence that actionrelated information can indeed affect perceptual confidence judgements (Faivre, Filevich, Solovey, Kühn, & Blanke, 2018;Faivre et al, 2020;Fleming et al, 2015;Palser, Fotopoulou, & Kilner, 2018;Pereira et al, 2020;Siedlecka, Hobot, et al, 2019;Siedlecka, Paulewicz, & Koculak, 2020;Wokke, Achoui, & Cleeremans, 2020). For example, Fleming and colleagues (2015) applied single-pulse TMS to the dorsal premotor cortex before and after responses during a visual discrimination task.…”

Confidence in perceptual decision-making is preserved in schizophrenia

“…The link between confidence and trajectories in the control group corroborates the view that sensorimotor signals shape confidence estimates. Indeed, previous studies showed that electromyographic activity (Gajdos, Fleming, Saez Garcia, Weindel, & Davranche, 2019) and alpha power over somatosensory scalp regions (Faivre, Filevich, Solovey, Kuhn, & Blanke, 2018) covary with confidence, and that altering sensorimotor signaling by increasing movement speed (Palser, Fotopoulou, & Kilner, 2018) or by inducing sensorimotor conflicts (Faivre, Vuillaume, et al, 2019) disrupt metacognitive accuracy. The weaker link between trajectories and confidence in schizophrenia may be related to slower and noisier motor behavior, or to the tendency of patients to neglect relevant internal cues to control motor actions (Frith, Blakemore, & Wolpert, 2000) .…”
