The attraction–similarity model and dating couples: Projection,perceived similarity,and psychological benefits

According to the attraction–similarity model, relationship quality leads to perceptions of partner–self similarity. Relationship quality and perceived similarity then provide psychological benefits for the perceiver. Across 3 studies, relationship quality positively predicted perceptions of similarity. Study 1 indicated that for moderate, but not low, relationship‐relevant traits, individuals projected the self onto the dating partner as a way of perceiving similarities. In Study 2, priming high, as opposed to low, relationship quality led to greater perceived similarity on the moderately relevant traits. Study 3 indicated greater perceived similarity between self and dating partner than between self and average same‐gender student on the moderately relevant traits. Relationship quality and perceived similarity with the dating partner on the moderately relevant traits also predicted psychological benefits.
