范围-频率理论关注的是类别判断，比如”好”和”坏”，或者”大"、”中”和”小“。“一个特定的模型从两个基本假设中得出判断：（a）法官将他的心理范围划分为相对大小与刺激条件无关的子范围;（B）他以相等的频率使用替代类别。该模型使用相同频率刺激时得到的判断来预测不同频率刺激时的判断。这些数据也被用来评估适应水平的加权平均模型。结果表明，范围-频率理论比适应水平理论更能解释类别判断。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
The range-frequency theory is concerned with category judgments, like" good" and" bad," or" large,"" medium," and" small." A specific model derives the judgments from 2 basic assumptions:(a) The judge divides his psychological range into subranges whose relative sizes are independent of the stimulus conditions; and (b) he employs the alternative categories with equal frequency. The model uses judgments obtained when stimuli are presented with equal frequency to predict the judgments when stimuli are presented with unequal frequencies. These data are also used to evaluate the weighted-mean model for adaptation level. It is concluded that category judgments are more adequately explained by the range-frequency theory than by the theory of adaptation level.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
