35 psychology graduate students in 4 experiential groups rated their attraction to each other after the 6th and 12th weekly meeting. Variance due to relationship effects in attraction was substantially larger than either actor or partner individual difference effects. There were significant individual differences in eliciting but not in giving attraction. Findings extend earlier research and demonstrate the incremental validity of studying relationship effects separately from individual difference effects in interpersonal attraction. The simultaneous study of individual differences and relationship effects offer the possibility of determining the relative contribution of these 2 types of effects.
