四个实验比较了不等概率锚定和选择性顺应对语音判断和非语音判断的影响。基本刺激序列是一个范围从/b/到/d/的合成停止辅音连续体。在这个连续体上叠加了基频、强度或元音的协变。在每个实验中，受试者在两种判断条件下听相同的测试磁带：发音位置，以及音调或响度或元音判断。在锚定范式和适应范式下，两种判断显著分离，表明前者的选择性不亚于后者。从这一点和其他证据可以得出结论，这两种范式在原则上是等价的，而且影响言语适应效果的主要因素是外周疲劳和中枢听觉对比。如果采用疲劳和对比的选择性过程来反映分析的功能通道，而不是特征检测器的操作，那么在言语和非言语适应中都可以看到相同的广泛过程。
A series of four experiments compared the effects of unequal probability anchoring and selective adaptation on phonetic and nonphonetic judgments. The basic stimulus series was a synthetic stop consonant continuum ranging from /b/ to /d/. On this continuum were superimposed covariations in fundamental frequency, intensity or vowel. In each experiment subjects listened to identical test tapes under two judgment conditions: place of articulation, and pitch or loudness or vowel judgments. The two types of judgment were significantly dissociated under both anchoring and adaptation paradigms, thus demonstrating that the former may be no less selective than the latter. From this and other evidence, it was concluded that the two paradigms are, in principle, equivalent, and that the main factors in speech adaptation effects are peripheral fatigue and central auditory contrast. If the selective processes of fatigue and contrast are taken to reflect functional channels of analysis rather than the operation of feature detectors, the same broad processes can be seen at work in both speech and nonspeech adaptation.
