在实验中我，20名本科生按照指令依次举起了3个重量，以判断最后一个重量的重量。与适应水平理论相反，这些判断没有表现出对比效应；相反，它们表现出了一种小的积极背景(同化)效应。在实验中第二，40名大学生按顺序举重2次，然后判断第1次或第2次的重量。再一次，观察到了一个小的积极的背景效应。对于高权重和低权重的同类序列，也得到了负的时序效应，这也与适应水平理论相反。(参考文献24)
In Exp. I, 20 undergraduates lifted 3 weights in sequence under instructions to judge the heaviness of the last weight. Contrary to adaptation-level theory, these judgments failed to show a contrast effect; instead they showed a small positive context (assimilation) effect. In Exp. II, 40 undergraduates lifted 2 weights in sequence and then judged the heaviness of the 1st or the 2nd. Again, a small positive context effect was observed. A negative time-order effect was also obtained for homogeneous sequences, both of high and of low weights, also contrary to adaptation-level theory.(24 ref.)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
