Previous studies have documented moderate-to-large associations between ratings of physical attractiveness and other interpersonal traits, but this research has invariably relied on within-subjects designs that leave open the possibility of halo effects or response biases. In the present study, 40 men completed the Photographic Figure Rating Scale in a within-subjects design, rating the figures for physical attractiveness, health, and suitability as a long-term partner. In addition, 108 men completed the same scale in a between-subjects design, being randomly allocated to one of three subgroups where they rated the figures for attractiveness, health, or suitability as a long-term partner. Results indicated no significant differences in ratings for the within-subjects participants. In contrast, there were significant differences in ratings for the between-subjects design. These results highlight the importance of considering halo and response bias effects when designing studies of interpersonal judgements and interpreting their results.
以往的研究记录了身体吸引力评分与其他人际特质之间存在中度到较大的关联，但这项研究始终依赖于被试内设计，这使得光环效应或反应偏差的可能性无法排除。在本研究中，40名男性以被试内设计完成了《照片身材评定量表》，对身材的吸引力、健康状况以及作为长期伴侣的合适程度进行评分。此外，108名男性以被试间设计完成了相同的量表，他们被随机分配到三个亚组之一，在其中对身材的吸引力、健康状况或作为长期伴侣的合适程度进行评分。结果表明，被试内参与者的评分没有显著差异。相比之下，被试间设计的评分存在显著差异。这些结果凸显了在设计人际判断研究并解释其结果时考虑光环效应和反应偏差效应的重要性。
