Ovulatory cycle shifts in human motivational prioritisation of sex and food.

Previous research on the endogenous effects of ovarian hormones on motivational states in women has focused on sexual motivation. The Motivational Priority Shifts Hypothesis has a broader scope. It predicts a shift from somatic to reproductive motivation when fertile. In a highly powered preregistered online diary study across 40 days, we tested whether 390 women report such an ovulatory shift in sexual and eating motivation and behaviour. We compared 209 naturally cycling women to 181 women taking hormonal contraceptives (HC) to rule out non-ovulatory changes across the cycle as confounders. We found robust ovulatory decreases in food intake and increases in general sexual desire, in-pair sexual desire and initiation of dyadic sexual behaviour. Extra-pair sexual desire increased mid-cycle, but the effect did not differ significantly in HC women, questioning an ovulatory effect. Descriptively, solitary sexual desire and behaviour, dyadic sexual behaviour, appetite, and satiety showed expected mid-cycle changes that were diminished in HC women, but these failed to reach our strict preregistered significance level. Our results provide insight into current theoretical debates about ovulatory cycle shifts while calling for future research to determine motivational mechanisms behind ovulatory changes in food intake and considering romantic partners' motivational states to explain the occurrence of dyadic sexual behaviour.

The Role of Agreeableness, Neuroticism, and Relationship-Specific Features in Self- and Other-Perceptions of Conflict Frequency in Adolescent Relationships with Parents and Peers.

Conflict frequency in adolescence has been linked to personality and relationship-specific features. However, an integrative investigation of both aspects is lacking. To address this gap, this study used data from 571 individuals in middle adolescence (Study 1; Mage = 15.86, SD = 1.23; 75.8% female) and 233 individuals in late adolescence (Study 2; Mage = 17.17, SD = 1.01; 75.5% female) in Germany, including participants' self-reports on conflict frequency and other-reports provided by parents and peers. Across studies, multigroup models revealed that adolescents' level of neuroticism predicted self- and other-perceived conflict frequency in parent and peer relationships more consistently than agreeableness, while providing no evidence for an interplay between both personality traits. Furthermore, relationship-specific features differentially accounted for individual differences in conflict frequency across relationship types, such that in adolescents' relationships with parents, lower relationship quality related to more frequent conflicts. In peer relationships, higher contact frequency was linked to more frequent conflicts. The present findings highlight the contributions of both personality and relationship-specific features to conflict frequency in adolescence and offer practical guidance for the improvement of adolescents' and their relationship partners' social skills and experiences.

Popularity at first sight: Dominant behaviours mediate the link between extraversion and popularity in face-to-face and virtual group interactions.

Although there is robust evidence that being more extraverted is related to higher popularity, only few studies have examined which actual behaviours (e.g., verbal content, body language) might explain this association. The current study examined whether observer-rated dominant behaviours (nonverbal, paraverbal, verbal, and general cues) mediate the relationship between self-rated extraversion and its facets (assertiveness, sociability, and activity) and other-rated popularity in zero-acquaintance settings. In two studies, we analysed data from face-to-face (Study 1, N = 124) and virtual (Study 2, N = 291) group interactions where participants were videotaped while performing a task and subsequently rated each other on popularity. Across studies, extraversion and the facets assertiveness and sociability were consistently associated with higher popularity, while the role of dominant behaviours differed. In Study 1, only two nonverbal behaviours, dominant gestures and upright posture, mediated the association between extraversion and popularity. In Study 2, all four types of behavioural cues mediated the association between extraversion (facets) and popularity. We discuss how these findings provide insights into the mechanisms of attaining popularity at zero acquaintance in diverse social settings.

Boosting yourself? Associations between momentary self-esteem, daily social interactions, and self-esteem development in late adolescence and late adulthood.

Research over the past 2 decades has repeatedly shown that the evaluation of one's own worth-trait self-esteem-is closely linked to the quality of social relationships and perceptions of social inclusion. However, there is limited evidence on the dynamics between momentary self-esteem and perceptions of social inclusion in everyday life, as well as on their possible long-term (bottom-up) effects on the development of trait self-esteem. We addressed this research gap using longitudinal data from a German multimethodological study (N = 324) in which N = 235 late adolescents (Mage = 17.7; 76% female) and N = 89 older adults (Mage = 63.8; 64% female) were followed over 1 year. Based on three trait questionnaires with 6-month intervals and a 7-day experience-sampling burst at the first measurement point, we investigated momentary dynamics in self-esteem and longitudinal change by using multilevel and latent growth modeling. Results confirmed the positive association between momentary self-esteem and perceptions of social inclusion in everyday life, that is, self-esteem reactivity in both age groups. In addition, both self- and other-reports showed a consistent increase in trait self-esteem over 1 year. However, because the slope parameters did not indicate substantial interindividual variance, we were unable to test for bottom-up effects of self-esteem reactivity. We discuss the importance of daily social experiences for momentary self-esteem in late adolescence and late adulthood but also point to the need for further multimethodological research.

Age Effects on Women's and Men's Dyadic and Solitary Sexual Desire.

While most studies on sexuality in later life report that sexual desire declines with age, little is known about the exact nature of age effects on sexual desire. Using self-reported dyadic sexual desire relating to a partner, dyadic sexual desire relating to an attractive person, and solitary sexual desire from a large (N > 8000) and age diverse (14.6-80.2 years) online sample, the current study had three goals: First, we investigated relationships between men and women's sexual desire and age. Second, we examined whether individual differences such as gender/sex, sexual orientation, self-rated masculinity, relationship status, self-rated attractiveness, and self-rated health predict sexual desire. Third, we examined how these associations differed across sexual desire facets. On average, the associations between age and both men and women's sexual desire followed nonlinear trends and differed between genders/sexes and types of sexual desire. Average levels of all types of sexual desire were generally higher in men. Dyadic sexual desire related positively to self-rated masculinity and having a romantic partner and solitary desire was higher in people with same-sex attraction. We discuss the results in the context of the evolutionary hypothesis that predict an increase of sexual desire and female reproductive effort prior to declining fertility. Our findings both support and challenge beliefs about gender/sex specificity of age effects on sexual desire and highlight the importance of differentiating between desire types.

Gloomy and out of control? Consequences of the COVID-19 pandemic on momentary optimism in daily live of adolescents.

In the global COVID-19 pandemic, adolescents are regarded as especially burdened due to school closures and leisure activities being banned, often reducing peer contacts to zero. Experiencing restrictions while being uninvolved in decision-making processes left them with little control over their daily lives. Meanwhile, research highlights that optimism can act as a buffer against the impact of daily hassles and is considered an important resource for mental health. To understand the implications of the COVID-19 pandemic for adolescents' lives, this study examined how momentary perceived control and perceived personal and societal consequences of the COVID-19 pandemic relate to momentary optimism. Using experience-sampling data from N = 242 (M age = 15.89; 86% female) adolescents assessed during the second pandemic wave in Germany, multilevel modeling revealed positive associations between adolescents' momentary perceived control and their momentary optimism at both the within- and between-person level. Additionally, perceived consequences of the COVID-19 pandemic showed specific associations with momentary optimism: Whereas perceived societal consequences were directly related to lower momentary optimism, perceived personal consequences strengthened the relationship between momentary perceived control and optimism. These findings highlight the role of perceived control as an important resource for optimism both as a general tendency and within specific situations in daily life. This way, our results may shed light on how to support adolescent optimism during states of emergency, such as a worldwide pandemic.

Men are not aware of and do not respond to their female partner's fertility status: Evidence from a dyadic diary study of 384 couples.

Understanding how human mating psychology is affected by changes in female cyclic fertility is informative for comprehending the evolution of human reproductive behavior. Based on differential selection pressures between the sexes, men are assumed to have evolved adaptations to notice women's within-cycle cues to fertility and show corresponding mate retention tactics to secure access to their female partners when fertile. However, previous studies suffered from methodological shortcomings and yielded inconsistent results. In a large, preregistered online dyadic diary study (384 heterosexual couples), we found no compelling evidence that men notice women's fertility status (as potentially reflected in women's attractiveness, sexual desire, or wish for contact with others) or display mid-cycle increases in mate retention tactics (jealousy, attention, wish for contact or sexual desire towards female partners). These results extend our current understanding of the evolution of women's concealed ovulation and oestrus, and suggest that both might have evolved independently.

Understanding Loneliness in Adolescence: A Test of Competing Hypotheses on the Interplay of Extraversion and Neuroticism.

Given that adolescents often experience fundamental changes in social relationships, they are considered to be especially prone to loneliness. Meanwhile, theory and research highlight that both extraversion and neuroticism are closely intertwined with individual differences in loneliness. Extant research has explored the linear main effects of these personality traits, yet potential non-linear associations (e.g., exponential effects) and the potential interplay of extraversion and neuroticism (e.g., mutual reinforcement effects) remain unknown. We addressed these open questions using cross-sectional and one-year longitudinal data from two adolescent samples (overall N = 583, Mage = 17.57, 60.55% girls) and an information-theoretic approach combined with polynomial regression. Analyses showed little evidence for interaction effects but revealed non-linear effects in addition to the main effects of extraversion and neuroticism on loneliness. For example, the positive cross-sectional association between neuroticism and loneliness was stronger at higher neuroticism levels (i.e., exponential effect). Results differed across loneliness facets in that both traits predicted emotional loneliness, but only extraversion predicted social loneliness. Longitudinal analyses showed that loneliness changes were mainly related to neuroticism. We discuss results in the light of sample differences, elaborate on the importance to differentiate between emotional versus social aspects of loneliness, and outline implications for adolescent development.
