Do assortative preferences contribute to assortative mating for adiposity?

Assortative mating for adiposity, whereby levels of adiposity in romantic partners tend to be positively correlated, has implications for population health due to the combined effects of partners' levels of adiposity on fertility and/or offspring health. Although assortative preferences for cues of adiposity, whereby leaner people are inherently more attracted to leaner individuals, have been proposed as a factor in assortative mating for adiposity, there have been no direct tests of this issue. Because of this, and because of recent work suggesting that facial cues of adiposity convey information about others' health that may be particularly important for mate preferences, we tested the contribution of assortative preferences for facial cues of adiposity to assortative mating for adiposity (assessed from body mass index, BMI) in a sample of romantic couples. Romantic partners' BMIs were positively correlated and this correlation was not due to the effects of age or relationship duration. However, although men and women with leaner partners showed stronger preferences for cues of low levels of adiposity, controlling for these preferences did not weaken the correlation between partners' BMIs. Indeed, own BMI and preferences were uncorrelated. These results suggest that assortative preferences for facial cues of adiposity contribute little (if at all) to assortative mating for adiposity.     

Men's strategic preferences for femininity in female faces

Several evolutionarily relevant sources of individual differences in face preference have been documented for women. Here, we examine three such sources of individual variation in men's preference for female facial femininity: term of relationship, partnership status and self‐perceived attractiveness. We show that men prefer more feminine female faces when rating for a short‐term relationship and when they have a partner (Study 1). These variables were found to interact in a follow‐up study (Study 2). Men who thought themselves attractive also preferred more feminized female faces for short‐term relationships than men who thought themselves less attractive (Study 1 and Study 2). In women, similar findings for masculine preferences in male faces have been interpreted as adaptive. In men, such preferences potentially reflect that attractive males are able to compete for high‐quality female partners in short‐term contexts. When a man has secured a mate, the potential cost of being discovered may increase his choosiness regarding short‐term partners relative to unpartnered men, who can better increase their short‐term mating success by relaxing their standards. Such potentially strategic preferences imply that men also face trade‐offs when choosing relatively masculine or feminine faced partners. In line with a trade‐off, women with feminine faces were seen as more likely to be unfaithful and more likely to pursue short‐term relationships (Study 3), suggesting that risk of cuckoldry is one factor that may limit men's preferences for femininity in women and could additionally lead to preferences for femininity in short‐term mates.     

Employee Attachment: Implications for Supervisor Trustworthiness and Trust

Purpose

The purpose of this study was to investigate the role of adult attachment on perceptions of trustworthiness and trust in one’s supervisor. Specifically, we cast trustworthiness perceptions as the cognitive mechanisms by which attachment influences trust, which then influenced work outcomes.

Design/methodology/approach

Data on attachment, trustworthiness, and trust were obtained from employees, and performance ratings were provided by the employees’ direct supervisor (n = 353, 157 supervisors).

Findings

Secure and counterdependent attachment had a significant impact on trustworthiness perceptions, and secure attachment was also significantly related to trust, even in the presence of trustworthiness perceptions. Overdependent attachment had no significant influence on trustworthiness or trust perceptions.

Implications

Adult attachment influences one’s regulatory processes in interpersonal relationships and will certainly influence trust in one’s supervisor. Understanding the process by which attachment influences trust in one’s supervisor via trustworthiness perceptions provides a more comprehensive picture of how trust develops. This study provides evidence that adult attachment influences trustworthiness and trust simultaneously, which may be helpful in the selection process but also in managing the interpersonal aspect of the employee–supervisor relationship.

Originality/value

Though trust has been linked to attachment in the literature, no research has examined adult attachment and its influence on trustworthiness perceptions. Our paper provides an examination of attachment and its role in a comprehensive model of interpersonal trust. In addition, we examine attachments influence on trustworthiness and trust beyond the influence of propensity to trust, a commonly studied dispositional variable in the trust literature.

     

The costs and benefits of testing text materials

Tests have been shown to improve the later recall of tested information, a result known as the testing effect. Tests, however, can also impair the later recall of related information, an effect known as retrieval-induced forgetting. Although retrieval-induced forgetting has been demonstrated using a wide variety of materials, recent work suggests that learning information in the context of a coherent text passage may afford protection from retrieval-induced forgetting. In four experiments we explored the conditions under which retrieval-induced forgetting does and does not occur with such materials. We found that two factors—the coherence of the to-be-learned material and the competitiveness of retrieval practice—are important in determining whether retrieval-induced forgetting does or does not occur. Furthermore, even if retrieval-induced forgetting does occur, having the opportunity to restudy the forgotten information can prevent that forgetting from persisting. Taken together, these findings provide greater understanding of the costs and benefits of testing text materials, with possible implications for the optimisation of testing as a tool for learning in educational contexts.     

Paying attention to distress: What's wrong with rumination?

We explored the notion—derived from conceptualisations of mindfulness—that what makes attention to distress harmful is negative judgement about it. In Study 1 we examined factors of Nolen-Hoeksema's Ruminative Response Scale (RRS). A “Brooding” scale included items describing negative judgements of experience, and a “Reflection” scale, comprised items describing analysis of thoughts and feelings without obvious judgement. Correlations of Reflection with depression and thought suppression were lower than those for Brooding, but still significant, perhaps because all items implied some judgement. In Study 2, items were reworded to de-emphasise evaluative judgements (RRS-nonjudging) and compared to the original RRS. Although the factor structures of the original and RRS-nonjudging versions were essentially identical, the RRS-nonjudging Reflection scale was uncorrelated with depression and thought suppression, and was more highly correlated with emotional processing than was the original Reflection scale.     

Accuracy in discrimination of self-reported cooperators using static facial information

People readily ascribe personality traits to others and believe that faces hold important guides to character. Here we examined the relationship between static facial appearance and self-reported cooperation/defection using the prisoner’s dilemma (N = 193). Study 1 combined face images of those self-reporting they would be most and least likely to cooperate. The composites of cooperators were seen as more cooperative than non-cooperators. Study 2 demonstrated accuracy with ratings of individual faces. Masculinity of face shape was negatively related to self-reported cooperation for men, but not women. Further, ratings of smile intensity were positively, but not significantly, related to self-reported cooperation. Overall, individuals appear able judge the potential of others to cooperate from static facial appearance alone at rates greater than chance.     

Social Cognition and the So-Called Conjunction Fallacy

The so-called ‘conjunction effect’, in which participants incorrectly assert that an instance from the conjunction of two sets is more probable than an instance from one of the two conjoining sets alone, has been a source of debate as to whether it is a genuine fallacy of individual thinking or not. We argue that reasoning about individuals follows a different process than reasoning about sets. 35 participants took part in 3 tasks: a) one involving blocks of different sizes and colours designed to evoke set-based reasoning, b) one where a particular block was ‘individuated’ by stating that it represented a particular person, and c) the original Tversky and Kahneman (Psychological Review 90(4):293–315, 1983) ‘Linda’ problem. As predicted, set-based reasoning was significantly more prevalent for the blocks task than for the other two tasks. Participants’ reasons for their choices suggest that some individuals correctly use set-based logic in one task and a social reasoning process for the other tasks.
