Effect before Cause: Supramodal Recalibration of Sensorimotor Timing
BACKGROUND Our motor actions normally generate sensory events, but how do we know which events were self generated and which have external causes? Here we use temporal adaptation to investigate the processing stage and generality of our sensorimotor timing estimates. METHODOLOGY/PRINCIPAL FINDINGS Adaptation to artificially-induced delays between action and event can produce a startling perce...
متن کاملSensorimotor temporal recalibration within and across limbs.
Deciding precisely when we have acted is challenging, as actions involve a train of neural events spread across both space and time. Repeated delays between actions and consequent events can result in a shift, such that immediate feedback can seem to precede the causative act. Here we examined which neurocognitive representations are affected during such sensorimotor temporal recalibration, by ...
متن کاملBayesian causal inference drives temporal sensorimotor recalibration
How does the brain evaluate and represent the time interval between a sensorimotor pair of events like a button press and a flash? Psychophysical experiments have shown that the relative position in time of the two events is subject to contraction (causal/intentional binding) [1] and to adaptive shifts which lead to striking time-ordering reversal illusions (temporal recalibration) [2]. The sub...
متن کاملSensorimotor Recalibration Depends on Attribution of Sensory Prediction Errors to Internal Causes
Sensorimotor learning critically depends on error signals. Learning usually tries to minimise these error signals to guarantee optimal performance. Errors can, however, have both internal causes, resulting from one's sensorimotor system, and external causes, resulting from external disturbances. Does learning take into account the perceived cause of error information? Here, we investigated the ...
متن کاملThe Build-Up and Transfer of Sensorimotor Temporal Recalibration Measured via a Synchronization Task
The timing relation between a motor action and the sensory consequences of that action can be adapted by exposing participants to artificially delayed feedback (temporal recalibration). Here, we demonstrate that a sensorimotor synchronization task (i.e., tapping the index finger in synchrony with a pacing signal) can be used as a measure of temporal recalibration. Participants were first expose...
