能动性改变了主观的时间感和对感官刺激的敏感性。我们用心理物理学的方法量化了代理在脑内视听整合加工中的作用。在实验中，受试者和实验者按下两个按钮，分别产生视觉和听觉刺激。在两种情况下，参与者判断连续的视听刺激的时间顺序。结果表明，被试代理的参与显著提高了被试对产生的刺激时间判断的准确性。结果表明，主观时间感是动态变化的，受代理和感觉-运动偶然性的影响。
Agency alters the subjective sense of time and sensitivity to sensory stimulus. We quantified the effect of agency in the processing of audiovisual integration in the brain by psychophysical methods. In the experiment, either the subjects or the experimenter pressed two buttons, which generated a visual and an auditory stimulus respectively. Participants judged the temporal order of the successive audiovisual stimuli in both conditions. The results show that the involvement of subject's agency increased the accuracy of judgments for the timing of the generated stimuli significantly. It is indicated that the subjective sense of time changes in a dynamical manner affected by the involvement of agency and sensori-motor contingency.
