Conventionally, when choice is measured under concurrent schedules, all responses are included. However, the class of all responses consists of 2 sub-classes which are discriminable by their properties: Reinforced responses always equal obtained reinforcers, while unreinforced responses are free to vary. As a result, the inclusion of reinforced responses in choice measures results in sensitivity values in generalized matching that are biased toward larger values, and this bias becomes extreme in some combinations of overall response and reinforcer rates. Different ways of varying concurrent-schedule values also affect estimated sensitivity and the linearity between choice based on all responses and reinforcer ratios. To avoid spurious results and comparisons, and as a matter of good practice, generalized-matching fits and measures should be done using only unreinforced responses.

并发时间表：每个强化物的反应如何影响对强化敏感性的估计

传统上，当在并发计划下测量选择时，所有响应都包含在内。然而，所有反应的类别由 2 个子类组成，这些子类可以通过它们的属性区分：强化反应总是等于获得的强化物，而未强化反应可以自由变化。因此，在选择测量中包含强化反应会导致广义匹配中的敏感性值偏向较大的值，并且这种偏差在总体反应和强化剂率的某些组合中变得极端。改变并发时间表值的不同方式也会影响估计的敏感性和基于所有反应和强化剂比率的选择之间的线性。为了避免虚假的结果和比较，并且作为一个良好的做法，
