Given the frequency of relationships nowadays initiated online, where impressions from face photographs may influence relationship initiation, it is important to understand how facial first impressions might be used in such contexts. We therefore examined the applicability of a leading model of verbally expressed partner preferences to impressions derived from real face images and investigated how the factor structure of first impressions based on potential partner preference-related traits might relate to a more general model of facial first impressions. Participants rated 1,000 everyday face photographs on 12 traits selected to represent (Fletcher, et al. 1999, Journal of Personality and Social Psychology, 76, 72) verbal model of partner preferences. Facial trait judgements showed an underlying structure that largely paralleled the tripartite structure of Fletcher et al.'s verbal preference model, regardless of either face gender or participant gender. Furthermore, there was close correspondence between the verbal partner preference model and a more general tripartite model of facial first impressions derived from a different literature (Sutherland et al., 2013, Cognition, 127, 105), suggesting an underlying correspondence between verbal conceptual models of romantic preferences and more general models of facial first impressions.

This research used the minimal exposure paradigm to examine facial first impressions of traits of trustworthiness, status, and attractiveness, considered important in verbal models of partner preferences. Heterosexual participants rated opposite-sex faces comprising either naturalistic images or youthful-looking averaged faces on trustworthiness, status, and attractiveness following 33, 100, and 500 ms masked presentation. The pattern masks were phase scrambled to provide the same overall color composition, brightness, and spatial frequency content as the presented faces. Trustworthiness, status, and attractiveness judgments were all reliable at above-chance levels even at 33 ms presentation, and extra time (100 or 500 ms) only led to modest improvement in the correspondence with an independent set of time-unconstrained judgments. The increasing prevalence of online images and internet-based relationships make these findings timely and important.

Romantic relationship researchers often use self-report measures of partner preferences based on verbal questionnaires. These questionnaires show that partner preferences involve an evaluation in terms of underlying factors of vitality-attractiveness, statusresources, and warmth-trustworthiness. However, when people first encounter a potential partner, they can usually derive a wealth of impressions from their face, and little is known about the relationship between verbal self-reports and impressions derived from faces. We conducted four studies investigating potential parallels and differences between facial impressions and verbal self-reports. Study 1 showed that when evaluating highly variable everyday face images in a context that does not require considering them as potential partners, participants can reliably perceive the traits and factors that are related to partner preferences. However, despite being capable of these nuanced evaluations, Study 2 found that when asked to evaluate images of faces as potential romantic partners, participants' preferences become dominated by attractiveness-related concerns. Study 3 confirmed this dominance of facial attractiveness using morphed face-like images. Study 4 showed that attractiveness dominates partner preferences for faces even when task instructions imply that warmth-trustworthiness or status-resources should be of primary importance. In contrast to verbal questionnaire measures of partner preferences, evaluations of faces focus heavily on attractiveness, whereas questionnaire self-reports tend on average to prioritize warmth-trustworthiness over attractiveness. Evaluations of faces and verbal self-report measures therefore capture different aspects of partner preferences.
