We hypothesized that facial attractiveness represents a dual judgment, a combination of reward-based, sexual processes, and aesthetic, cognitive processes. Herein we describe a study that demonstrates that sexual and nonsexual processes both contribute to attractiveness judgments and that these processes can be dissociated. Female participants rated the general attractiveness of faces presented in either their left or right visual field. In order to examine sexual and nonsexual components of these judgments, general attractiveness ratings were correlated with ratings of these same faces made by two independent groups of raters in two specific contexts, one sexual and one nonsexual. Based on an items analysis, partial correlation coefficients were computed for each individual and used as the dependent variable of interest in a 2 (laterality: right, left) by 2 (context: sexual, nonsexual) ANOVA. This analysis revealed an interaction such that faces rated in a sexual context better predicted attractiveness ratings of faces shown in the left than right visual field, whereas faces rated in a nonsexual context better predicted attractiveness of faces shown in the right than left visual field. This finding is consistent with the assertion that sexual and nonsexual preferences involve predominantly lateralized processing routes that independently contribute to what is perceived to be attractive.
我们假设面部吸引力代表了一种双重判断，是基于奖赏的性过程和审美认知过程的结合。在此，我们描述了一项研究，该研究表明性和非性过程都有助于吸引力判断，并且这些过程可以分离。女性参与者对呈现于其左或右视野中的面孔的一般吸引力进行了评级。为了检验这些判断中的性和非性成分，将一般吸引力评级与由两组独立的评分者在两个特定情境（一个是性情境，另一个是非性情境）中对同一面孔的评级进行了相关性分析。基于项目分析，为每个个体计算了偏相关系数，并将其作为 2（侧性：右、左）×2（情境：性、非性）方差分析的因变量进行了分析。该分析揭示了一种交互作用，即性情境下的评级更好地预测了左视野中呈现的面孔的吸引力评级，而非性情境下的评级则更好地预测了右视野中呈现的面孔的吸引力评级。这一发现与以下断言一致，即性和非性偏好涉及主要的侧化处理途径，这些途径独立地影响到被认为是有吸引力的。
