This prediction was confirmed by the data, tð15Þ ¼ 2:11, p < :05. , pairs of countries from the same continent sharing a common border). Unlike Sjo¨berg’s3 study, which extended the context by introducing nonhomogeneous pairs, our experiment extended the context by constructing heterogeneous sets composed of homogeneous pairs. Hence, the increase of similarity with the enlargement of context, observed in the present study, cannot be explained by subjects’ tendency to equate the average similarity for any set of assessments.

The following three sections review and discuss our main findings, focusing primarily on the test of qualitative predictions. A more detailed description of the stimuli and the data are presented in Tversky and Gati (in press). Asymmetry and Focus According to the present analysis, similarity is not necessarily a symmetric relation. Indeed, it follows readily (from either the contrast or the ratio model) that sða; bÞ ¼ sðb; aÞ i¤ afðA À BÞ þ bfðB À AÞ ¼ afðB À AÞ þ bfðA À BÞ i¤ ða À bÞfðA À BÞ ¼ ða À bÞfðB À AÞ: Hence, sða; bÞ ¼ sðb; aÞ if either a ¼ b, or fðA À BÞ ¼ fðB À AÞ, which implies fðAÞ ¼ fðBÞ, provided feature additivity holds.

The referent). The choice of standard, therefore, determines the directionality of the comparison. A natural partial ordering of the letters with respect to prominence is induced by the relation of inclusion among letters. Thus, one letter is assumed to have a larger measure than another if the former includes the latter. For example, includes and but not . For all 19 pairs in which one letter includes the other, let p denote the more prominent letter and q denote the less prominent letter. Furthermore, let sða; bÞ denote the percentage of times that the subject judged the variable stimulus a to be the same as the standard b.
