Mental object rotation and the planning of hand movements

摘要: Recently, we showed that the simultaneous execution of rotational hand movements interferes with mental object rotation, provided axes rotation coincide in space. We hypothesized and programming share a common process presumably involved action planning. Two experiments are reported here show mere planning movement is sufficient to cause interference rotation. Subjects had plan different spatially directed they were asked execute only after solved task. Experiment 1 was slower if planned direction opposite presumed direction, but parallel 2 this occurred independent preparatory observed 1. Thus, it not their preparation or This finding underlines idea an imagined (covert) action, rather than pure visual-spatial imagery task, between goals actions.
