已知多模态信号的统计最优整合发生在与环境对象的直接交互中。在本研究中，我们测试了是否相同的机制是负责观察到的任务中，参与者包括视觉对象手动控制的视觉光标的知觉偏见。我们操纵的相对可靠性的视觉对象的信息和测量的影响，身体相关的信息对对象的知觉以及知觉的变异性。结果与统计学最佳感觉整合定性一致。然而，在定量方面，观察到的偏倚和变异性测量系统地不同于模型预测。这一结果表明，补偿机制类似的可靠性为基础的加权的多感官信号，可以根据行动的影响，在不同的背景条件下报告的视觉感知。
Statistically optimal integration of multimodal signals is known to take place in direct interactions with environmental objects. In the present study we tested whether the same mechanism is responsible for perceptual biases observed in a task, in which participants enclose visual objects by manually controlled visual cursors. We manipulated the relative reliability of visual object information and measured the impact of body-related information on object perception as well as the perceptual variability. The results were qualitatively consistent with statistically optimal sensory integration. However, quantitatively, the observed bias and variability measures systematically differed from the model predictions. This outcome indicates a compensatory mechanism similar to the reliability-based weighting of multisensory signals which could underlie action's effects in visual perception reported in diverse context conditions.
