Acetaminophen Reduces Social Pain Behavioral and Neural Evidence

Pain, whether caused by physical injury or social rejection, is an inevitable part of life. These two types of pain—physical and social—may rely on some of the same behavioral and neural mechanisms that register pain-related affect. To the extent that these pain processes overlap, acetaminophen, a physical pain suppressant that acts through central (rather than peripheral) neural mechanisms, may also reduce behavioral and neural responses to social rejection. In two experiments, participants took acetaminophen or placebo daily for 3 weeks. Doses of acetaminophen reduced reports of social pain on a daily basis (Experiment 1). We used functional magnetic resonance imaging to measure participants’ brain activity (Experiment 2), and found that acetaminophen reduced neural responses to social rejection in brain regions previously associated with distress caused by social pain and the affective component of physical pain (dorsal anterior cingulate cortex, anterior insula). Thus, acetaminophen reduces behavioral and neural responses associated with the pain of social rejection, demonstrating substantial overlap between social and physical pain.

Empathy gaps for social pain: why people underestimate the pain of social suffering.

In 5 studies, the authors examined the hypothesis that people have systematically distorted beliefs about the pain of social suffering. By integrating research on empathy gaps for physical pain (Loewenstein, 1996) with social pain theory (MacDonald & Leary, 2005), the authors generated the hypothesis that people generally underestimate the severity of social pain (ostracism, shame, etc.)--a biased judgment that is only corrected when people actively experience social pain for themselves. Using a social exclusion manipulation, Studies 1-4 found that nonexcluded participants consistently underestimated the severity of social pain compared with excluded participants, who had a heightened appreciation for social pain. This empathy gap for social pain occurred when participants evaluated both the pain of others (interpersonal empathy gap) as well as the pain participants themselves experienced in the past (intrapersonal empathy gap). The authors argue that beliefs about social pain are important because they govern how people react to socially distressing events. In Study 5, middle school teachers were asked to evaluate policies regarding emotional bullying at school. This revealed that actively experiencing social pain heightened the estimated pain of emotional bullying, which in turn led teachers to recommend both more comprehensive treatment for bullied students and greater punishment for students who bully.

Does physical pain augment anxious attachment

This study tested the hypothesis derived from social pain theory (MacDonald & Leary, 2005) that pain affect serves as a signal of perceived social exclusion. Participants ranging in experience of persistent physical pain completed measures of pain affect, anxious and avoidant attachment, anxiety, and depression. Higher levels of pain affect were found to relate to higher levels of anxious, but not avoidant, attachment. Further, anxious attachment partially mediated the relation between pain affect and emotional distress. These data support the conclusion that one reason individuals with persistent pain experience anxiety and depression is because of heightened concerns over rejection. The data also support the conclusion that anxious attachment is more strongly related to the fight–flight–freezing system than avoidant attachment.

Conflicting pressures on romantic relationship commitment for anxiously attached individuals.

Anxious attachment predicts strong desires for intimacy and stability in romantic relationships, yet the relation between anxious attachment and romantic commitment is unclear. We propose that extant literature has failed to find a consistent relation because anxiously attached individuals experience conflicting pressures on commitment. Data from Australia (N=137) show that relationship satisfaction and felt security each act as suppressors of a positive relation between anxious attachment and commitment. Data from Japan (N=159) replicate the suppression effect of felt security and also demonstrate that the residual positive relation between anxious attachment and commitment can be partly explained by dependence on the partner. These findings suggest that anxiously attached individuals may be ambivalent about commitment. Dissatisfaction and worries about negative evaluation appear to exert downward pressure on commitment, counteracting the upward pressure that is exerted by factors such as relational dependency.

On the Rebound: Focusing on Someone New Helps Anxiously Attached Individuals Let Go of Ex-Partners

The present research demonstrates that focusing on someone new may help anxiously attached individuals overcome attachment to an ex-romantic partner, suggesting one possible motive behind so-called rebound relationships. A correlational study revealed that the previously demonstrated link between anxious attachment and longing for an ex-partner was disrupted when anxiously attached individuals had new romantic partners. Two experiments demonstrated that this detachment from an ex can be induced by randomly assigning anxiously attached individuals to believe they will easily find a new partner (through bogus feedback in Study 2 and an ease of retrieval task in Study 3). This research suggests that for anxiously attached individuals, focusing on someone new can be an adaptive part of the breakup recovery process.

Mildly negative social encounters reduce physical pain sensitivity

&NA; While previous research has demonstrated a reduction in physical pain sensitivity in response to social exclusion, the manipulations employed have arguably been far removed from typical daily experience. The purpose of this study was to investigate the effects of relatively ordinary social encounters on the perception of pain. Healthy participants rated the intensity and unpleasantness of painful stimuli before and after engaging in a structured interaction with a confederate who was instructed to either be warm and friendly or indifferent. A control group was asked to perform a similar structured activity, but alone. Consistent with predictions, participants who experienced the mildly negative social exchange reported lower pain intensity and unpleasantness after the encounter relative to baseline, whereas those exposed to the positive social exchange did not evidence any change in pain ratings. These results were not mediated by changes in mood or perceived connectedness. If mildly negative social encounters can provoke an analgesic effect, it is possible that social hypoalgesia may be considerably more commonplace than previously realized. Discussion focuses on the role of stress‐induced hypoalgesia, and the implications of the results for clinical assessments of pain.

The Things You Do for Me: Perceptions of a Romantic Partner’s Investments Promote Gratitude and Commitment

Although a great deal of attention has been paid to the role of people’s own investment in promoting relationship commitment, less research has considered the possible role of the partner’s investments. An experiment (Study 1) and two combined daily experience and longitudinal studies (Studies 2 and 3) documented that perceived investments from one partner motivate the other partner to further commit to the relationship. All three studies provided support for gratitude as a mechanism of this effect. These effects held even for individuals who were relatively less satisfied with their relationships. Together, these results suggest that people feel particularly grateful for partners who they perceive to have invested into the relationship, which, in turn, motivates them to further commit to the relationship. Implications for research and theory on gratitude and relationship commitment are discussed.

Don’t Get Your Hopes Up Avoidantly Attached Individuals Perceive Lower Social Reward When There Is Potential for Intimacy

We examine whether lower expectations for social reward selectively applied to high intimacy contexts may help avoidantly attached individuals minimize distress from reward loss. Studies 1, 2, and 4 demonstrated that avoidant attachment was negatively associated with perceived intimacy potential in relationships involving approach of closeness (current/future partners), but not for relationships less associated with approach of closeness (ex-partners). Studies 3 and 5 manipulated the potential for intimacy among dating prospects. Avoidant attachment was negatively associated with romantic interest in high intimacy targets but not low intimacy targets. This effect was mediated by perceived responsiveness. Studies 4 and 5 rule out perceived dissimilarity to responsive targets as a mechanism. Study 6 demonstrated that avoidants’ lower expectations for connection are associated with less anticipated distress from reward loss. These results suggest that avoidant individuals may circumvent attachment system activation by perceiving lower opportunity for connection when there is potential for intimacy.

Insecure attachment predicts ambivalent social threat and reward perceptions in romantic relationships

Although theoretical perspectives on adult attachment forward relational ambivalence as a defining characteristic of at least some forms of insecurity, work demonstrating an ambivalent structure to the relational attitudes of insecure individuals has been rare. The current research examines the similarity and intensity of perceptions of social threat (i.e., concerns over rejection) and social reward (i.e., opportunities for intimacy) in romantic relationships. Using a sample of 1004 participants, evidence for relational ambivalence was found for both anxious and avoidant attachment. Individuals high in anxious attachment reported relatively similar and intense threat and reward perceptions, whereas individuals high in avoidant attachment showed evidence of similar, but not intense, threat and reward perceptions. Thus, the weighing of prospects for rejection and intimacy in romantic relationships arguably leads to what researchers traditionally think of as ambivalence for those high in attachment anxiety, but something more akin to indifference for those high in attachment avoidance. More broadly, this work provides a set of tools and methods for carefully examining ambivalence in close relationships.

Romantic Relationships Conceptualized as a Judgment and Decision-Making Domain

We review the emerging evidence suggesting that the largely separate research areas of romantic relationships and judgment and decision making (JDM) can usefully inform each other. First, we present evidence that decisions in more traditional JDM domains (e.g., consumerism, economics) share important features with romantic-relationship decisions, including the use of formal decision strategies (e.g., the investment model), intuitive shortcuts (e.g., the availability heuristic), and anticipated emotions (e.g., affective forecasting). In turn, we present evidence suggesting that incorporating key concepts from the field of relationships (e.g., need to belong, attachment style) can enrich traditional JDM domains. These largely unrecognized overlaps between relationship decisions and decisions made in more traditional decision-making domains suggest that the fields of relationship science and JDM—each of which contains a wealth of existing theory, findings, and research tools—could be used to illuminate one another for mutual benefit.
