The effect of movement kinematics on predicting the timing of observed actions

摘要: The ability to predict the actions of other agents is vital for joint action tasks. Recent theory suggests that prediction relies on an emulator system permits observers use a model their own movement kinematics agents. If this case, then people should be more accurate at generating predictions about are similar own. We tested hypothesis in two experiments which participants were required occurrence and timing particular critical points observed action. In Experiment 1, we employed self/other paradigm accuracy recordings self-generated movements was compared with other-generated movements. As expected, because case observer stimuli maximally similar. able produce tempo and, therefore, results might explained terms self-similarity production rather than kinematics. To control possibility 2, matched but differed only showed when predicting human kinematic profile tempo-matched moved non-human Finally, 3, confirmed 2 cannot by human-like containing slowing down phase before points. Taken together, these findings provide further support role motor emulation prediction, they suggest mechanism produces output available rapidly drive suggesting it can plausibly coordination.
