在三个键延迟和同步匹配样本的任务中，不同的鸽子组匹配波长刺激。在这个任务中，只有当鸽子直接站在键的前面时，才能看到样本和比较。鸟类的定位运动表明，它们经常选择一个比较，而从来没有看到它的替代品。这些观测数据被用来产生基于刺激和决策过程（马尔可夫）的可辨性的匹配行为理论。提出了“匹配”标准，即如果比较刺激符合这些标准，则接受它们与样本匹配。不符合这些标准的比较被拒绝为匹配，并产生观察切换到重复决策过程的替代比较。匹配标准是可以操纵的，并且要求鸽子做出更困难的区分，从而注意到更细微的色调差异，从而使匹配标准变得更加严格。用两个不匹配的比较刺激进行的测试表明，在不匹配很大的特殊情况下，鸽子在试验中放松了他们的标准。
Separate groups of pigeons matched wavelength stimuli in three-key delayed and simultaneous matching-to-sample tasks in which samples and comparisons could be viewed only when the birds positioned themselves directly in front of the keys. The birds' positioning movements indicated that they frequently chose a comparison without ever seeing its alternative. These observational data were used to generate a theory of matching behavior based on the discriminability of the stimuli and decision processes (Markov) governing choice responding. "Match" criteria are proposed whereby comparison stimuli are accepted as matches to the sample if they meet these criteria. Comparisons not meeting these criteria are rejected as matches and produce observational switches to the alternative comparison where the decision process is repeated. Match criteria were shown to be manipulable and were made stricter by requiring the pigeons to make more difficult discriminations and thereby notice more subtle hue differences. Tests with two nonmatching comparison stimuli demonstrated that in unusual situations in which the mismatch is great, the pigeons relaxed their criteria during the trial.
