稳定的物体知觉依赖于在不断波动的刺激条件下持续而暂时的神经表征。这种表征形成和维持的机制尚未完全理解，但可能涉及早期和更高层次视觉皮层机制之间的相互作用。早期视皮层特征结合的神经生理学模型预测了在特定刺激条件下持续的轮廓知觉。在这里，我们表明，轮廓持久性的持续时间反映了视觉机制的持续操作敏感的轮廓平滑度，这也影响轮廓的可见性更普遍地在高度刺激条件下。我们区分轮廓的平滑度对轮廓持久性的影响，从观察者的偏见，这也有助于令人惊讶的长时间的轮廓持久性。我们的结论是，轮廓的平滑性对持久性的强烈调节作用是由于视觉皮层的局部和全局轮廓绑定机制的持续混响，这形成了知觉连续性和稳定的物体知觉的重要基础。
Stable object perception relies on persistent yet temporary neural representations under constantly fluctuating stimulus conditions. The mechanisms by which such representations are formed and maintained are not fully understood but presumably involve interplay between early and higher tier visual cortical mechanisms. Some neurophysiological models of feature binding in early visual cortex predict persistent contour perception under certain stimulus conditions. Here we show that the duration of contour persistence reflects the persistent operation of visual mechanisms sensitive to contour smoothness, which also influences contour visibility more generally under highly camouflaging stimulus conditions. We distinguish the effect of contour smoothness on contour persistence from observer bias, which also contributes to the surprisingly long duration of contour persistence. We conclude that the strong modulatory effects of contour smoothness on persistence are due to the sustained reverberation of local and global contour-binding mechanisms in visual cortex, which form an important basis of perceptual continuity and stable object perception.
