Friends with benefits: the evolved psychology of same- and opposite-sex friendship

During human evolution, men and women faced distinct adaptive problems, including pregnancy, hunting, childcare, and warfare. Due to these sex-linked adaptive problems, natural selection would have favored psychological mechanisms that oriented men and women toward forming friendships with individuals possessing characteristics valuable for solving these problems. The current study explored sex-differentiated friend preferences and the psychological design features of same- and opposite-sex friendship in two tasks. In Task 1, participants (N = 121) categorized their same-sex friends (SSFs) and opposite-sex friends (OSFs) according to the functions these friends serve in their lives. In Task 2, participants designed their ideal SSFs and OSFs using limited budgets that forced them to make trade-offs between the characteristics they desire in their friends. In Task 1, men, more than women, reported maintaining SSFs for functions related to athleticism and status enhancement and OSFs for mating opportunities. In Task 2, both sexes prioritized agreeableness and dependability in their ideal SSFs, but men prioritized physical attractiveness in their OSFs, whereas women prioritized economic resources and physical prowess. These findings suggest that friend preferences may have evolved to solve ancestrally sex-linked adaptive problems, and that opposite-sex friendship may directly or indirectly serve mating functions.     

Divergent effects of different positive emotions on moral judgment

Positive emotions are often treated as relatively similar in their cognitive-behavioral effects, and as having unambiguously beneficial consequences. For example, Valdesolo and DeSteno (2006) reported that a humorous video made people more prone to choose a utilitarian solution to a moral dilemma. They attributed this finding to increased positive affect. To determine whether such results actually stem in general from positive affect or from other more specific properties of humor, we conducted an experiment with moral dilemmas presented during an interleaved emotion-induction procedure involving mirth and another positive emotion, elevation. Mirth increased permissiveness for deontological violations, whereas elevation had the opposite effect. Furthermore, affective valence had no apparent independent influence on these judgments. Our results suggest that mirth and elevation have distinct cognitive consequences whose properties reflect their respective social functions, not their shared positive valence.     

‘Not in our front garden’: Land use conflict,spatial meaning and the politics of naming place

Strategies aimed at reducing land use conflict often stress the need to make planning decisions more democratic. However, this goal is obstructed by overly‐narrow conceptual perspectives that neglect the symbolic significance of place. We illustrate this by examining place names, which function as repositories of socio‐political meaning. Drawing on elements of discursive and rhetorical psychology and subject positioning theory, we investigated the variety of meanings associated with place names in the context of a proposed housing development in Swindon, in the South of England. Thirty interviews with different stakeholders were conducted to gauge their opinions towards the proposal. Noting differences in the way the proposed site was named, we analysed the range of meanings associated with each name in relation to participants' stances towards development. Our results show how, in naming place, spatial meanings are negotiated and contested in ways that support contrasting political objectives. We conclude that planning professionals should exercise greater sensitivity towards existing spatial meanings, especially place names. In addition, socio‐political understandings of subjective spatial relationships can serve as a basis for achieving more productive dialogue and improving development designs.

On positive psychological outcomes: what helps groups with a history of conflict to forgive and reconcile with each other?

Three studies examined the roles of traditional and novel social psychological variables involved in intergroup forgiveness. Study 1 (N = 480) revealed that among the pro-Pinochet and the anti-Pinochet groups in Chile, forgiveness was predicted by ingroup identity (negatively), common ingroup identity (positively), empathy and trust (positively), and competitive victimhood (the subjective sense of having suffered more than the outgroup, negatively). Political ideology (Right vs. Left) moderated the relationship between empathy and forgiveness, trust and forgiveness, and between the latter and competitive victimhood. Study 2 (N = 309), set in the Northern Irish conflict between Protestants and Catholics, provided a replication and extension of Study 1. Finally, Study 3 (N = 155/108) examined the longitudinal relationship between forgiveness and reconciliation in Northern Ireland, revealing that forgiveness predicted reconciliation intentions. The reverse direction of this relationship was also marginally significant. Results are discussed in terms of their theoretical and practical implications.     

Constrained action selection in children with developmental coordination disorder

The effect of advance ('precue') information on short aiming movements was explored in adults, high school children, and primary school children with and without developmental coordination disorder (n=10, 14, 16, 10, respectively). Reaction times in the DCD group were longer than in the other groups and were more influenced by the extent to which the precue constrained the possible action space. In contrast, reaction time did not alter as a function of precue condition in adults. Children with DCD showed greater inaccuracy of response (despite the increased RT). We suggest that the different precue effects reflect differences in the relative benefits of priming an action prior to definitive information about the movement goal. The benefits are an interacting function of the task and the skill level of the individual. Our experiment shows that children with DCD gain a benefit from advance preparation in simple aiming movements, highlighting their low skill levels. This result suggests that goal-directed RTs may have diagnostic potential within the clinic.     

Not Always Enslaved,Yet Not Quite Free: Philosophical Challenges from the Underside of the New World

This article is the keynote address of the University of the West Indies at Cave Hill, Barbados, philosophy symposium in celebration of the 200th Anniversary of the British outlawing the Atlantic Slave Trade. The paper explores questions of enslavement and freedom through challenges of philosophical anthropology, philosophy of social change, and metacritical reflections posed by African Diasporic or Africana philosophy. Such challenges include the relevance and legitimacy of philosophical reflection to the lives of racialized slaves and concludes with a discussion of the implications of the analysis for an understanding of the “face” of political life and the importance of the concept of “home” for a cogent theory of freedom.

The Zuni Life Skills Development Program: a school/community-based suicide prevention intervention

The Zuni Life Skills Development Program, an effective community-initiated and high-school-based suicide prevention intervention, is featured. Development and evaluation of this intervention are followed by note of the specific challenges associated with stabilizing the program. A more tribally diverse, culturally-informed model entitled the American Indian Life Skills Development Curriculum is then presented to illustrate a hybrid approach to the cultural tailoring of interventions. This curriculum is broad enough to address concerns across diverse American Indian tribal groups yet respectful of distinctive and heterogeneous cultural beliefs and practices. Finally, we reflect upon issues in community-based research that emerged during this collaboration.     

21st birthday celebratory drinking: evaluation of a personalized normative feedback card intervention.

This research was designed to evaluate a personalized normative feedback birthday card intervention aimed at reducing normative perceptions, alcohol consumption, and negative consequences associated with 21st birthday celebrations among college students (N=281; 59.15% women). Students were randomly assigned to receive or not receive a birthday card about 1 week prior to their 21st birthday. Approximately 1 week following their birthday, students were asked to complete a brief survey concerning their birthday celebration activities. Findings indicated that the birthday card intervention was not successful at reducing drinking or consequences; however, the card did reduce normative misperceptions. Additional findings indicated that many students experienced negative consequences, such as passing out or driving after consuming alcohol. Combined, these findings suggest that prevention is needed for drinking associated with turning 21. However, prevention efforts should consist of more than a birthday card.
