Susceptibility to the fusion illusion is modulated during both action execution and action observation

摘要: Abstract Many researchers have proposed that when an individual observes the actions of another individual, observer simulates action using many same neural areas are involved in production. The present study was designed to test this simulation hypothesis by comparing perception multisensory stimuli during both execution and observation aiming action. work used fusion illusion - audio-visual which two visual presented with one auditory stimulus erroneously perceived as being stimulus. Previous research has shown that, execution, susceptibly is reduced early movement information may be more highly weighted than other sensory information. We sought determine whether or not a non-acting showed similar reduction susceptibility illusion. Participants fixated target either executed observed manual target. Audiovisual were at 0, 100, 200 ms relative onset participants reported number flashes after completed. Analysis revealed less susceptible (100 ms) later (200 ms). Critically, pattern emerged tasks. These findings support observers simulate performance actor experience comparable real-time alterations processing.
