For several modalities, it has been shown that the processing of sensory information generated by our own actions is attenuated relative to the processing of sensory information of externally generated stimuli. It has been proposed that the underlying mechanism builds predictions about the forthcoming sensory input and forwards them to the respective(More)
Numerous studies have shown that the N1 event-related potential (ERP) response is attenuated when it is elicited by self-initiated sounds. This N1 suppression effect is generally interpreted to reflect an internal prediction mechanism, which enables the discrimination of the sensory consequences of our own actions and those of others. The blocked design(More)
When sharing a task with another person that requires turn taking, as in doubles games of table tennis, performance on the shared task is similar to performing the whole task alone. This has been taken to indicate that humans co-represent their partner's task share, as if it were their own. Task co-representation allows prediction of the other's responses(More)
Social interactions fill our everyday life and put strong demands on our brain function. However, the possibilities for studying the brain basis of social interaction are still technically limited, and even modern brain imaging studies of social cognition typically monitor just one participant at a time. We present here a method to connect and synchronize(More)
Forward predictions are crucial in motor action (e.g., catching a ball, or being tickled) but may also apply to sensory or cognitive processes (e.g., listening to distorted speech or to a foreign accent). According to the "internal forward model," the cerebellum generates predictions about somatosensory consequences of movements. These predictions simulate(More)
When individuals share a task with a partner, one’s own actions and one’s partner’s actions have to be precisely tuned to one another. With behavioral means, it has been numerously shown that splitting a simple reaction time task between two participants produces similar interference patterns to those occurring when controlling the whole task on one’s own.(More)
The N1 auditory ERP and its magnetic counterpart (N1[m]) are suppressed when elicited by self-induced sounds. Because the N1(m) is a correlate of auditory event detection, this N1 suppression effect is generally interpreted as a reflection of the workings of an internal forward model: The forward model captures the contingency (causal relationship) between(More)
HYPERSCANNING Most neuroimaging studies of human social cognition have focused on brain activity of single subjects. More recently, "two-person neuroimaging" has been introduced, with simultaneous recordings of brain signals from two subjects involved in social interaction. These simultaneous "hyperscanning" recordings have already been carried out with a(More)
