Female college students in the United States were given the option of
working with a similar or dissimilar peer on a set of difficult math p
roblems. The peer was identified as either an English or a math major.
Potential partners with relevant expertise (math majors) were rated a
s liked better than the English majors. However, this finding occurred
only on the liking item of the Interpersonal Judgment Scale (US). The
re was no effect of academic major on the working-with item or the tra
ditional composite measure. These results were interpreted in terms of
self-presentation and may indicate a limitation of the IJS as a metho
d of measuring attraction.
