- Abstract
Psychological studies of relationships tend to focus on specific types of close personal relationships (romantic, parent-offspring, friendship) and examine characteristics of both the individuals and the dyad. This paper looks more broadly at the wider range of relationships that constitute an individual's personal social world. Recent work on the composition of personal social networks suggests that they consist of a series of layers that differ in the quality and quantity of relationships involved. Each layer increases relationship numbers by an approximate multiple of 3 (5-15-50-150) but decreasing levels of intimacy (strong, medium, and weak ties) and frequency of interaction. To account for these regularities, we draw on both social and evolutionary psychology to argue that relationships at different layers serve different functions and have different cost-benefit profiles. At each layer, the benefits are asymptotic but the costs of maintaining a relationship at that level (most obviously, the time that has to be invested in servicing it) are roughly linear with the number of relationships. The trade-off between costs and benefits at a given level, and across the different types of demands and resources typical of different levels, gives rise to a distribution of social effort that generates and maintains a hierarchy of layered sets of relationships within social networks. We suggest that, psychologically, these trade-offs are related to the level of trust in a relationship, and that this is itself a function of the time invested in the relationship.

- Abstract
Cooley et al. (2017) found that subtle shifts in linguistic framing can enhance the amount of "mind" perceived in a target, and in turn increase feelings of sympathy toward that target. The four studies reported here evaluated whether these findings generalize to different populations and contexts. The first two studies served as conceptual replications in a different participant population (university students, instead of mTurk workers), and found results largely consistent with Cooley et al.'s (2017): the group composition frame ("15 individuals who work for a small accounting company") evoked greater perceptions of experience and agency, and more sympathy for the target, than the group frame ("a small accounting company comprising 15 people"). Studies 3 and 4 tested whether the group composition technique would lead to similar persuasive outcomes (increased mind perception, helping, and donations) in a refugee aid context and found only limited evidence that it might. These inconclusive findings were likely complicated by both the liberal skew of the sample and the strong impact of political identity on responses to the politically charged topic of refugees. For the purposes of practical application, an expanded understanding of boundary effects can help provide a better sense of when, why, and on whom the use of adjusted linguistic frames is most likely to be effective.

- Abstract
Although the benefits of sport participation for older adults has been well-documented, the traditionally masculine sport of weightlifting has only recently become popular among older women, who now participate at rates comparable to men in the United States. This study describes the self-reported effects of participating in Masters-level Olympic weightlifting on other aspects of life. Contrasting with previous studies of Masters athletes in other sports, the gender balance and broad age range of our sample allowed us to explore whether the self-reported impact of sport on older adults was similar or different across age groups (35-44, 45-59, 60, and older) for both men and women. A total of 352 (191 women, 159 men, 2 other) who completed a survey of Masters lifters registered with the United States national organization (USAW) responded to an open-ended question about how weightlifting has affected other aspects of their life. Across gender and age categories, responses indicated that weightlifting has a positive impact on physical health (strength, mobility, fitness) and on psychological (mental health benefits, stress reduction) and social aspects such as community connections. Female lifters mentioned psychological benefits such as increased confidence and help with stress and depression more commonly than male lifters; older lifters were more likely than middle-aged lifters to mention physical health benefits. Competition was a prominent theme across genders and age groups. The themes mentioned by participants are consistent with previous literature on sports that are less strongly gender-typed than weightlifting., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Huebner, Arrow, Garinther and Meltzer.)

10. Victim Number Effects in Charitable Giving: Joint Evaluations Promote Egalitarian Decisions.

- Abstract
Studies of victim number effects in charitable giving consistently find that people care more and help more when presented with an appeal to help an individual compared with an appeal to help multiple people in need. Across three online experiments ( N = 1,348), Bayesian estimation revealed the opposite pattern when people responded to multiple appeals to help targets of different sizes (1, 2, 5, 7, and 12). In this joint evaluation context, participants donated more to larger groups, when appeals were presented in both ascending order (Study 1) and random order (Study 2). The pattern held whether or not participants saw an overview of all appeals at the start of the study and when a single individual was added to the array (Study 3). These results clarify how compassion fade findings typical of separate evaluations may not generalize to contexts in which people encounter multiple appeals within a short temporal window.

- Abstract
Background: Olympic weightlifting requires strength, speed, and explosive power. Vigorous physical activity such as Olympic weightlifting, for older adults has many benefits from improved strength, social interactions, and a healthy and independent lifestyle. Little is known about the training habits, health, and lifestyle of Masters weightlifters that includes top level athletes as well as beginners, and there is a dearth of data on women., Objectives: The primary aim was to describe demographics, training habits, and health including prevalence of injury and chronic disease in male and female Masters athletes in Olympic weightlifting. The secondary aim was to study gender differences and the age and impact of menopause on participation in the sport., Results: The 958 participants (46% men), ages 34 to 87, mostly train 3 to 4 days per week in 1 to 2 hour sessions. This is a highly educated and affluent group, 84% are white, 72% are married, 85% are post-secondary graduates. Exercise can also increase the risk of injury compared to less active older adults, but the rates of injury in weightlifting affecting training are lower than seen in other sports. The prevalence of depression and mental health is similar to a general population. Stress levels and sleep disturbances are more common among women than men. Women reach menopause at a similar age as women in industrialized countries, but menopausal symptoms constrained the training., Conclusion: Older athletes are capable of rigorous training programs and top performances while adjusting to changes due to biological aging. Weightlifting athletes, coaches, and health professionals must be aware of patterns of injuries and gender differences to incorporate successful prevention strategies. Knowledge of presentations of menopause and impact of menopausal symptoms on training allows women and health care providers to make informed treatment decisions., Competing Interests: The authors have declared that no competing interests exist.

13. Friendship trumps ethnicity (but not sexual orientation): comfort and discomfort in inter-group interactions.

- Abstract
An experience sampling study tested the degree to which interactions with out-group members evoked negative affect and behavioural inhibition after controlling for level of friendship between partners. When friendship level was statistically controlled, neither White nor Black participants reported feeling more discomfort interacting with ethnic out-group members compared to ethnic in-group members. When partners differed in sexual orientation, friendship level had a less palliating effect. Controlling for friendship, both gay and straight men - but not women - felt more behaviourally inhibited when interacting with someone who differed in sexual orientation, and heterosexual participants of both genders continued to report more negative affect with gay and lesbian interaction partners. However, gay and lesbian participants reported similar levels of negative affect interacting with in-group (homosexual) and out-group (heterosexual) members after friendship level was controlled. Results suggest that much of the discomfort observed in inter-ethnic interactions may be attributable to lower levels of friendship with out-group partners. The discomfort generated by differences in sexual orientation, however, remains a more stubborn barrier to comfortable inter-group interactions., (©2011 The British Psychological Society.)

- Abstract
An experience sampling study examined the degree to which feeling stereotyped predicts feelings of low power and inhibition among stigmatized and nonstigmatized individuals. For 7 days, participants with a concealable (gay and lesbian), a visible (African American), or no identifiable stigma recorded feelings of being stereotyped, of powerlessness, and of inhibition immediately following social interactions. For members of all three groups, feeling stereotyped was associated with more inhibition, and this relation was partially mediated by feeling low in power. Although stigmatized participants reported feeling stereotyped more often than nonstigmatized participants, they reacted less strongly to the experience, consistent with the presence of buffering mechanisms developed by those living with stigma. African Americans appeared to buffer the impact of feeling stereotyped more effectively than gay and lesbian participants, an effect that was partly attributable to African Americans' higher identity centrality.

- Abstract
This article presents an evolutionary framework for understanding the sexual assault of women in the military. We specify the evolutionary underpinnings of tensions among heterosexual males, among heterosexual females, and between males and females and discuss how these tensions have played out in the strongly gendered context of warrior culture. In the absence of cultural interventions that take into account deep-seated conceptions of women in the military as unwelcome intruders, sexual resources for military men, or both, military women operate in an environment in which sexual assault may be deployed to enact and defend traditional military structures. We discuss how unit norms are likely to affect the choice of strategies by men and by women and how the resulting behaviors-including celibacy, consensual sex, and sexual assault-should affect horizontal and vertical unit cohesion. The framework is intended to guide future data collection in theoretically coherent ways and to inform the framing and enforcement of policies regarding both consensual and non-consensual sex among military personnel.

- Abstract
Rationale: Multidisciplinary groups are common in the health care arena, from operating teams to mental health treatment groups to guideline development groups. Differences among group members in information, background, training and skills can potentially help groups reach good decisions and complete complex tasks in variable circumstances. Too often, however, differences in values, status and preferences prevent these groups from achieving the potential benefits of diversity, marooning them instead in an unproductive fixed state., Aim: Drawing on the literature on diversity and complex adaptive systems, we discuss how to improve the functioning of multidisciplinary groups by increasing the spontaneous flow of information and energy to shift groups into the complex state., Conclusion: Differentiation needs to be balanced by integration. Differences that pose obstacles need to be transformed into gradients to achieve complex self-organization and effective group coordination.
