人类与许多动物一样具有数字感，即快速估计场景中物品的大致数量的能力。最近的研究表明，像许多其他感知属性一样，数字很容易适应。然而，尚不清楚适应是直接作用于对数量选择性的机制，还是通过相关机制，例如那些调整到纹理密度的机制。为了解决这个问题，我们测量了 10 对连接点的数量适应性，因为连接点使它们看起来比未连接点的数量少。适应 20 点图案（与测试的点数相同）会导致连接点图案的表观数量大幅减少，但未连接点图案的表观数量不会大幅减少。这表明，对数字的适应，至少对于相对稀疏的点图案，发生在编码感知数字的神经水平上，而不是在响应场景中元素数量的较低水平上。
Humans share with many animals a number sense, the ability to estimate rapidly the approximate number of items in a scene. Recent work has shown that like many other perceptual attributes, numerosity is susceptible to adaptation. It is not clear, however, whether adaptation works directly on mechanisms selective to numerosity, or via related mechanisms, such as those tuned to texture density. To disentangle this issue we measured adaptation of numerosity of 10 pairs of connected dots, as connecting dots makes them appear to be less numerous than unconnected dots. Adaptation to a 20-dot pattern (same number of dots as the test) caused robust reduction in apparent numerosity of the connected-dot pattern, but not of the unconnected dot-pattern. This suggests that adaptation to numerosity, at least for relatively sparse dot-pattern, occurs at neural levels encoding perceived numerosity, rather than at lower levels responding to the number of elements in the scene.
