| Abstract: | Contextual effects due to attribute range were examined in single-attribute and multiattribute judgments. The effect of a given attribute difference was greater when presented in a narrow range than a wide range. Stretching and shrinking the ranges of attributes altered the rank orders of judgments assigned to the same stimuli in different ranges. Trade-offs between time and money, between 1 measure of ability and another, and between achievement and motivation depended on attribute range. Although changes in trade-offs can result from changes in weights, data were consistent with the hypothesis that attribute range influences scale values. Scale values for common levels of an attribute spanned a wider interval when the attribute range was narrow than when the attribute range was wide.
