Attribute Range and Response Range: Limits of Compatibility in Multiattribute Judgment

Previous research suggests that attributes may have greater effects on judgment when attribute scales and response scales are compatible. We examine a particular form of compatibility, similarity of ranges, and test between two theories of attribute range and response range effects. Two groups of subjects rated the overall class performance of students as described by two exam scores and an essay grade. An identical set of exam scores was presented in narrow and wide exam ranges. One group made performance ratings using a narrow response scale, and the other rated performance with a wide response scale. In both response range conditions, the effect of the common attribute levels was greater for the narrow exam range than for the wide exam range. This finding is inconsistent with a range-compatibility hypothesis which predicts that the effect of an attribute depends on the compatibility between attribute range and response range. Results are consistent with a range-frequency hypothesis in which the same attribute levels span a greater range of subjective values when presented in a narrow attribute range, regardless of the response scale.
