Journal Article 1: Chow, C. M., Ruhl, H., & Buhrmester, D. (2016). Reciprocal associations between friendship attachment and relational experiences in adolescence. Journal of Social & Personal Relationships, 33, 122–146.

Abstract: The current study examined the reciprocal associations between friendship attachment and relational experiences. Data came from a longitudinal study that assessed adolescents (N = 223, 108 girls) in the 6th, 8th, 10th, and 12th grades. Cross-lagged models were fitted with structural equation modeling. Results showed that attachment avoidance was consistently predictive of more friendship exclusion, and friendship exclusion was consistently predictive of more attachment anxiety. Attachment avoidance was consistently related to less friendship intimacy across adolescence. Friendship intimacy was also consistently related to lower attachment avoidance across adolescence. Attachment anxiety was consistently related to more friendship intimacy across adolescence. This study shed light on the bidirectional influences between attachment security and relational experiences in adolescent friendships.

Journal Article 2: Chung, S., Lount, R. B., Jr., Park, H. M., & Park, E. S. (2018). Friends with performance benefits: A meta-analysis on the relationship between friendship and group performance. Personality and Social Psychology Bulletin, 44, 63–79.

Abstract: The current article examines if, and under which conditions, there exists a positive relationship between working with friends and group performance. To do so, using data from 1,016 groups obtained from 26 studies, we meta-analyzed comparisons of the performance of friendship groups versus acquaintance groups. Results show that friendship has a significant positive effect on group task performance (Cohen’s d = 0.31). Furthermore, this relationship was moderated by group size (i.e., the positive effect of friendship on performance increased with group size) and task focus (i.e., friendship groups performed better than acquaintance groups on tasks requiring a high quantity of output, whereas there was no performance benefit on tasks requiring a single or high-quality output). These results help to reconcile mixed findings and illustrate when friendship groups are more likely to perform better than acquaintance groups.

Journal Article 3: Farrelly, D., Clemson, P., & Guthrie, M. (2016). Are women’s mate preferences for altruism also influenced by physical attractiveness? Evolutionary Psychology, 14, 1–6.

Abstract: Altruism plays a role in mate choice, particularly in women’s preferences and in long-term (LT) relationships. The current study analyzed how these preferences interacted with another important mate choice variable, physical attractiveness. Here, female participants were presented with photographs of men of varying levels of physical attractiveness, alongside descriptions of them behaving either altruistically or not in different scenarios. The results showed women preferred altruistic men, particularly in LT relationships and that this interacted with physical attractiveness such that being both attractive and altruistic made a man more desirable than just the sum of the two desirable parts. Also, being altruistic made low attractive men more desirable but only for LT relationships. Finally, men who were just altruistic were rated more desirable than men who were just attractive, especially for LT relationships. Overall, these findings are discussed in terms of the role of altruism in mate choice, particularly in LT relationships and directions of future research.

Journal Article 4: Lemay, E. P., & Wolf, N. R. (2016). Projection of romantic and sexual desire in opposite-sex friendships: How wishful thinking creates a self-fulfilling prophecy. Personality and Social Psychology Bulletin, 42, 864–878.

Abstract: In two studies, the authors examined the projection of romantic and sexual desire in opposite-sex friendships. In both studies, perceivers who strongly desired their friends projected this desire onto their friends, believing that their desire was more reciprocated than was actually the case. In turn, projection of desire appeared to motivate perceivers into enacting relationship initiation behaviors, which predicted changes in targets’ romantic and sexual desires over time (Study 2). Projection was elevated for perceivers who saw themselves as high in mate value, and targets appeared to be influenced by perceivers’ overtures primarily when they believed perceivers were high in mate value. This research suggests that, for perceivers high in mate value, romantic and sexual desire creates biased perceptions that initiate self-fulfilling prophecies.
