The systematic association of an action that a person performs with its sensory effects is thought to attenuate person’s perception the effect action. However, whether learned sensorimotor contingencies truly affect perception, rather than just inducing response bias, has yet be determined. experiment presented in this article comprised two parts: action-effect phase and test phase, during which actions’ perceptual were tested. During specific actions (left-key right-key presses) associated...

The ability to recognize oneself in voluntary action is called the sense of agency and refers experience causing one's own actions their sensory consequences. This form self-awareness important not only for motor control but also social interactions ascription causal responsibility. Here, we examined at early prereflective stages perception using ERPs. Subjects performed a visual forced-choice response task which effects were either caused by subject or computer. In addition, modulate...

In the standard Simon task, participants carry out spatially defined responses to non-spatial stimulus attributes. Responses are typically faster when location and response correspond. This effect disappears a participant responds only one of two stimuli reappears another person carries other response. social (SSE) has been considered as providing an index for action co-representation. Here, we investigated whether joint-action effects in task involve mechanisms co-representation, measured...

Joint actions require the integration of simultaneous self- and other-related behaviour. Here, we investigated whether this function is underpinned by motor simulation, that capacity to represent a perceived action in terms neural resources required execute it. This was tested music performance experiment wherein on-line brain stimulation (double-pulse transcranial magnetic stimulation, dTMS) employed interfere with simulation. Pianists played right-hand part piano pieces synchrony recording...

The capacity to distinguish between one's own and others' behavior is a cognitive prerequisite for successful joint action. We employed musical action task investigate how the brain achieves this distinction. Pianists performed right-hand part of piano pieces, previously learned bimanually, while complementary left-hand either was not executed or (believed be) played by co-performer. This experimental setting served induce co-representation reflecting self Single-pulse transcranial magnetic...

Abstract Action inhibition, the suppression of action impulses, is crucial for goal-directed behaviour. In order to dissociate neural mechanisms specific motor stopping from general control processes which are also relevant other types conflict adjustments, we compared midfrontal oscillatory activity in human volunteers via EEG between inhibition and two conflicts, unexpected activation change. Error rates indicated that was significantly easier than equally demanding tasks. Midfrontal brain...

Predicting the actions of other individuals is crucial for our daily interactions. Recent evidence suggests that prediction object-directed arm and full-body employs dorsal premotor cortex (PMd). Thus, neural substrate involved in action control may also be essential prediction. Here, we aimed to address this issue hypothesized disrupting PMd impairs Using fMRI-guided coil navigation, rTMS (five pulses, 10 Hz) was applied over left vertex (control region) while participants observed everyday...

Sensory attenuation refers to the observation that self-generated stimuli are attenuated, both in terms of their phenomenology and cortical response compared same when generated externally. Accordingly, it has been assumed sensory might help individuals determine whether a event was caused by themselves or not. In present study, we investigated this dependency is reciprocal, namely modulated prior beliefs authorship. Participants had judge loudness auditory effects they believed were either...

Generating predictions during action observation is essential for efficient navigation through our social environment. With age, the sensitivity in prediction declines. In younger adults, network (AON), consisting of premotor, parietal and occipitotemporal cortices, has been implicated transforming executed observed actions into a common code. Much less known about age-related changes neural representation actions. Using fMRI, present study measured brain activity older adults temporarily...

Abstract Sensory events produced by ourselves are known to lead lower neural and perceptual impact than sensory from other environmental sources. This attenuation is widely assumed result control processes that specific our own motor actions, potentially helping us distinguish effects others. However, previous research cannot rule out the putative self‐attenuation in fact reflect actor‐independent, general predictive mechanisms, which, direct comparison, just highlight external due...

Abstract The perception of internal bodily signals (interoception) is central to many theories emotion and embodied cognition. According recent theoretical views, the sensory processing visceral such as one's own heartbeat determined by top‐down predictions about expected interoceptive state body (interoceptive inference). In this EEG study we examined neural responses heartbeats following unexpected emotional stimuli. We used a modified stimulus repetition task in which pairs facial...

Numerous studies suggest that both self-generated and observed actions of others activate overlapping neural networks, implying a shared, agent-neutral representation self other. Contrary to the shared hypothesis, we recently showed human motor system is not neutral with respect agent an action [Schütz-Bosbach, S., Mancini, B., Aglioti, S. M., & Haggard, P. Self other in system. Current Biology, 16, 1830-1834, 2006]. Observation attributed another facilitated system, whereas observation...

Abstract Linking observed and executable actions appears to be achieved by an action observation network (AON), comprising parietal, premotor, occipitotemporal cortical regions of the human brain. AON engagement during is thought aid in effortless, efficient prediction ongoing movements support understanding. Here, we investigate how responds when observing predicting cannot readily reproduce before after visual training. During pre‐ posttraining neuroimaging sessions, participants watched...
