Thirty subjects read descriptions of 4 bogus strangers and rated their own feelings and their attraction toward the described persons. The descriptions were products of a 2 x 2 factorial design, having the Row factor of the subjects' evaluations by the stranger (positive vs. negative) and the Column factor of attitude similarity between the subjects and stranger (.00 and 1.00). Results indicated that personal evaluation was more powerful than attitude similarity as a determinant of the subjects' feelings as well as of their attraction toward the target persons. Support for the notion that the same stimulus-combination law could be applied to the ratings of one's affective state and his evaluative response was also impressive. In general, the findings were consistent with Byrne's reinforcement-affect theory of interpersonal attraction.
