Topic: Sensory attenuation

Sensory Attenuation (SA) refers to the phenomenon that self-generated stimuli are perceived less intensely than externally generated sensations. Recent findings, however, suggest that SA is a phenomenon mostly linked to prediction rather than intentional actions. With the present study, we aimed at interrogating this question.The study consisted of a VR setup and a simultaneous EEG recording. Participants were required to either actively touch or passively get touched by a virtual ball that gave them (or not) an electrical stimulation at the finger, in a probabilistic manner. Participants had

Previous research has shown that the N1 responses are attenuated for sensory consequences of self-initiated actions compared to externally-initiated sensory consequences. This illustrates the existence of prediction mechanisms allowing the differentiation between self and externally generated events. Previous studies provided evidence for modulated N1 responses following self-initiated sounds or pictures. A recent study showed attenuated N1 responses also for self-initiated auditory-visual stimuli. The present study investigated the impact of temporal synchrony of the auditory and visual stimu
