3D运动感知对日常生活至关重要。然而，当在实验室环境中进行测试时，发现对3D运动信号的敏感性很差，导致启发式和先验假设对3D运动感知至关重要的观点。在这里，我们探索了另一种选择：对3D运动信号的敏感性依赖于上下文，必须基于新环境中的明确视觉反馈来学习。在发展的文献中，对随行动而生的视觉反馈的需要是公认的。例如，小猫被被动地移动到一个环境中，但不能自己移动，不能发展准确的深度感知。我们发现，这些原则同样适用于成年人的感知。即使长时间暴露在虚拟现实环境中，没有体验到其行为视觉后果的观察者也无法在虚拟现实环境中形成准确的3D运动感知。相比之下，体验到自己行为后果的观察者会根据3D运动的感官线索提高表现。具体来说，我们发现观察者学会利用头部抖动提供的小运动视差线索。我们的研究结果促进了对人类3D运动处理的理解，并为未来在虚拟和自然3D环境中的感知研究奠定了基础。
3D motion perception is of central importance to daily life. However, when tested in laboratory settings, sensitivity to 3D motion signals is found to be poor, leading to the view that heuristics and prior assumptions are critical for 3D motion perception. Here we explore an alternative: sensitivity to 3D motion signals is context-dependent and must be learned based on explicit visual feedback in novel environments. The need for action-contingent visual feedback is well-established in the developmental literature. For example, young kittens that are passively moved through an environment, but unable to move through it themselves, fail to develop accurate depth perception. We find that these principles also obtain in adult human perception. Observers that do not experience visual consequences of their actions fail to develop accurate 3D motion perception in a virtual reality environment, even after prolonged exposure. By contrast, observers that experience the consequences of their actions improve performance based on available sensory cues to 3D motion. Specifically, we find that observers learn to exploit the small motion parallax cues provided by head jitter. Our findings advance understanding of human 3D motion processing and form a foundation for future study of perception in virtual and natural 3D environments.
