刺激背景(刺激值的分布)可以强烈地影响感知和判断。在14个实验中，量值估计方法揭示了响度中两种根本不同的背景效应。当刺激一维变化(仅强度)时，同化效应占主导地位。但当刺激(频率和强度)多维变化时，一种对比性或适应性的效应占主导地位。在实验15中，直接响度比较揭示了特定于信号频率的有效的适应性过程。综上所述，这些和其他结果与以下观点是一致的，即响度感知和判断反映了两个不同语境过程的净结果：相对早期(尽管可能不是外围的)感知适应过程和较晚的依赖反应的同化过程。
Stimulus context (the distribution of stimulus values) can strongly affect both perception and judgment. In 14 experiments, the method of magnitude estimation revealed 2 fundamentally different kinds of context effect in loudness. An assimilative effect dominated when stimuli varied unidimensionally (in intensity only). But a contrastive, or adaptationlike, effect dominated when stimuli varied multidimensionally (in frequency and intensity). In Exp 15, direct loudness comparison revealed a potent, adaptational process specific to the signal frequency. Taken together, these and other results are compatible with the view that loudness perception and judgment reflect the net outcome of 2 different contextual processes: a relatively early (though probably not peripheral) process of perceptual adaptation and a later process of response-dependent assimilation.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
