Compatibility between Observed and Executed Finger Movements: Comparing Symbolic, Spatial, and Imitative Cues

摘要: Intuitively, one can assume that imitating a movement is an easier task than responding to symbolic stimulus like verbal instruction. Support for this suggestion be found in neuropsychological research as well on stimulus-response compatibility. However controlled experimental evidence assumption still lacking. We used compatibility paradigm test the assumption. In series of experiments, it was tested whether observed finger movements have stronger influence execution or spatial cue. first experiment, we compared cues with using interference paradigm. Observing strongly influenced execution, irrespective relevant irrelevant dimension. second effects and were compared. The dominated A reduction similarity executed action third experiment led decrease movement, which demonstrates crucial role imitative relation described effects. results are discussed recent models Neurocognitive support strong relationship between observation reported.
