大多数计算和神经风格的轮廓完成模型（即虚幻和闭塞的轮廓）是基于插值：填充两个可见边缘之间的边缘。三个实验的结果提出了另一种概念，即单位是从可见的边缘外推的结果。在三个实验中，受试者报告的错觉轮廓之间的标准illusory-contour诱导元素和形式，不通过自己，诱导错觉轮廓。我们认为，这些形式不是一个特殊的情况下，诱导元素，但他们代表了一个不同的类接收元素。接收元素是可以接收虚幻轮廓但不能生成轮廓的形式，它们可以改变轮廓的形成。在实验1中，接收元件增加了判断的清晰度虚幻的轮廓。在实验2中，虚幻的边缘被视为连接到角落，线的两端，甚至圆的边缘。运动显示中的边界形成似乎也是基于外推法。在实验3中，受试者报告说，小的移动点改变了时空定义的边界的形成。高阶算子和网络模型的边界形成的影响进行了讨论。
Most computational and neural-style models of contour completion (ie illusory and occluded contours) are based on interpolation: the filling in of an edge between two visible edges. The results of three experiments suggest an alternative conception, that units are formed as a result ofextrapolationfrom visible edges. In three experiments, subjects reported illusory contours between standard illusory-contour inducing elements and forms that do not, by themselves, induce illusory contours. We suggest that these forms are not a special case of inducing elements but that they represent a different class—receiving elements. Receiving elements are forms that can receive an illusory contour but cannot generate one, and they can alter contour formation. In experiment 1, receiving elements increased the judged clarity of illusory contours. In experiment 2, illusory edges were seen to connect to corners, line ends, and even the edges of circles. Boundary formation in motion displays also appears to be based on extrapolation. In experiment 3, subjects reported that small moving dots altered the formation of spatiotemporally defined boundaries. Implications for higher-order operator and network models of boundary formation are discussed.
