| Abstract: | Coupled people, those in a relationship, devaluate the attractiveness of an alternative partner compared to noncoupled people (D. J. Johnson & C. E. Rusbult, 1989). The present research tested two competing hypotheses about the mechanisms underlying this phenomenon. According to the motivational hypothesis, coupled and noncoupled people initially perceive opposite‐sex others as equally attractive. Coupled people, however, recalibrate their perceptions. In contrast, the perceptual hypothesis proposes that coupled people do not perceive opposite‐sex others as attractive. The present study tested these competing hypotheses by measuring both involuntary and self‐reported perceptions of attractiveness of opposite‐sex models. Supporting the motivational hypothesis, coupled participants (n = 38) and noncoupled participants (n = 34) exhibited the same degree of pupil dilation, however, coupled participants reported lower attractiveness ratings. |
