Oxytocin has been shown to be important for social behavior and emotional attachments in early life and may also mediate effects of early experiences on social motivation in adulthood. In animal models, early maternal separation results in alterations in the oxytocin system, with effects on sexual, maternal, and stress reactivity behaviors in adulthood. Studies of children experiencing parental divorce find effects on mood disorders, substance abuse, and other behaviors in adulthood. Here, we examine the effect of divorce on adult urine oxytocin levels. To stimulate oxytocin release, participants, aged 18 to 62, were asked to complete a set of questionnaires on attachment style, parental history of divorce (age at parental divorce ranged from 0 to 20), and other measures. A sample of urine was then collected for the oxytocin assay. Urine oxytocin concentrations were substantially lower (p = .016) in subjects who experienced parental divorce (M = 3.70, Standard Error of the Mean = 0.73), compared to those who did not (M = 8.00, Standard Error of the Mean = 1.21), and correlated with responses on several attachment instruments. These results suggest that oxytocin levels are adversely affected by parental divorce in humans and may be related to attachment measures in adulthood.

What is unknown, however, is the extent to which those changes are transient or enduring. To investigate this issue, we followed a sample of over 4,000 people in a multiwave longitudinal study in which people naturalistically experienced a variety of life events (e.g., starting new relationships, changing jobs, average n across events = 392). This allowed us to examine people's attachment trajectories before (Mwaves = 6.51) and after (Mwaves = 8.04) specific life events took place, for spans of time ranging from 6 months to 40 (M = 23 months). We found that half of the life events we studied were associated with immediate changes in attachment styles. However, on average, people tended to revert back to levels of security similar to those that would be expected on the basis of their preevent trajectories. Nonetheless, the average person changed in enduring ways in response to a quarter of the events we studied, suggesting that some experiences lead to enduring changes in attachment. Moreover, there were considerable individual differences in the extent to which people changed Even in cases in which the average person did not show enduring change, there was evidence that some people became more secure and others less so in enduring ways. The ways in which people construed the events (positive vs. negative) were related to the extent to which their attachment styles changed. We discuss the implications of these findings for theoretical models of attachment dynamics.

We focused on the potential of nonnormative nonviolent action as a tactic to generate support for concessions among advantaged group members who are resistant to social change. We propose that this tactic, relative to normative nonviolent and to violent action, is particularly effective because it reflects constructive disruption a delicate balance between disruption (which can put pressure on the advantaged group to respond) and perceived constructive intentions (which can help ensure that the response to action is a conciliatory one). We test these hypotheses across 4 contexts (total N = 3650). Studies 1-3 demonstrate that nonnormative nonviolent action (compared with inaction, normative nonviolent action, and violent action) is uniquely effective at increasing support for concessions to the disadvantaged among resistant advantaged group members (compared with advantaged group members more open to social change). Study 3 shows that constructive disruption mediates this effect. Study 4 shows that perceiving a real-world ongoing protest as constructively disruptive predicts support for the disadvantaged, whereas Study 5 examines these processes longitudinally over 2 months in the context of an ongoing social movement. Taken together, we show that nonnormative nonviolent action can be an effective tactic for generating support for concessions to the disadvantaged among those who are most resistant because it generates constructive disruption.

We sought to examine whether minority and majority group members (i.e., Black and White Americans) would differentially judge instances of cultural exchange as cultural appropriation. Five experiments (3 were preregistered on OSF) using a variety of potential cases of cultural appropriation demonstrated that Black participants were more likely than White participants to view these incidents as appropriation when they involved White perpetrators appropriating Black culture (vs. scenarios of Black perpetrators appropriating White culture), an effect mediated by distinctiveness threat. Black (vs. White) participants were also more likely to perceive White actors who appropriate Black culture as harmful and as intentional. In Study 4, explicit manipulation of distinctiveness threat eliminated the participant race effect Perceivers viewed White perpetrators as more appropriative than Black perpetrators. When actors were portrayed as using either an ingroup or outgroup cultural product (Study 5), participants perceived use of an outgroup cultural product as more appropriative. Studies 3-5 were preregistered on OSF. This research illuminates how group-based status interacts with and adds to perpetrator prototypically to influence perceptions of cultural appropriation, distinguishes perception of appropriation from perception of racism, and points to the importance of distinctiveness threat as a contributor to differential race-based perceptions. Implications of perceiving cultural appropriation for intergroup relations are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
