Curiosity protects against interpersonal aggression: cross-sectional, daily process, and behavioral evidence.

OBJECTIVE: Curiosity is the propensity to recognize and seek out new information and experience, including an intrinsic interest in learning and developing one's knowledge. With few exceptions, researchers have often ignored the social consequences of being curious. METHOD: In four studies using cross-sectional (N = 64), daily diary (Ns = 150 and 110, respectively), and behavioral experimental (N= 132) designs, we tested the hypothesis that individual differences in curiosity are linked to less aggression, even when people are provoked. RESULTS: We showed that both trait and daily curiosity were linked to less aggressive responses toward romantic relationship partners and people who caused psychological hurt. In time-lagged analyses, daily curiosity predicted less aggression from one day to the next, with no evidence for the reverse direction. Studies 3 and 4 showed that the inverse association between curiosity and aggression was strongest in close relationships and in fledgling (as opposed to long-lasting) romantic relationships. That is, highly curious people showed evidence of greater context sensitivity. Intensity of hurt feelings and other personality and relationship variables failed to account for these effects. CONCLUSIONS: Curiosity is a neglected mechanism of resilience in understanding aggression.

The voodoo doll task: Introducing and validating a novel method for studying aggressive inclinations.

Aggression pervades modern life. To understand the root causes of aggression, researchers have developed several methods to assess aggressive inclinations. The current article introduces a new behavioral method-the voodoo doll task (VDT)-that offers a reliable and valid trait and state measure of aggressive inclinations across settings and relationship contexts. Drawing on theory and research on the law of similarity and magical beliefs (Rozin, Millman, & Nemeroff [1986], Journal of Personality and Social Psychology, 50, 703-712), we propose that people transfer characteristics of a person onto a voodoo doll representing that person. As a result, causing harm to a voodoo doll by stabbing it with pins may have important psychological similarities to causing actual harm to the person the voodoo doll represents. Nine methodologically diverse studies (total N = 1,376) showed that the VDT had strong reliability, construct validity, and convergent validity. Discussion centers on the importance of magical beliefs in understanding the causes of aggressive inclinations.

Gratitude and depressive symptoms: the role of positive reframing and positive emotion.

Eight studies (N=2,973) tested the theory that gratitude is related to fewer depressive symptoms through positive reframing and positive emotion. Study 1 found a direct path between gratitude and depressive symptoms. Studies 2-5 demonstrated that positive reframing mediated the relationship between gratitude and depressive symptoms. Studies 6-7 showed that positive emotion mediated the relationship between gratitude and depressive symptoms. Study 8 found that positive reframing and positive emotion simultaneously mediated the relationship between gratitude and depressive symptoms. In sum, these eight studies demonstrate that gratitude is related to fewer depressive symptoms, with positive reframing and positive emotion serving as mechanisms that account for this relationship.

Benefits of expressing gratitude: expressing gratitude to a partner changes one's view of the relationship.

This research was conducted to examine the hypothesis that expressing gratitude to a relationship partner enhances one's perception of the relationship's communal strength. In Study 1 (N = 137), a cross-sectional survey, expressing gratitude to a relationship partner was positively associated with the expresser's perception of the communal strength of the relationship. In Study 2 (N = 218), expressing gratitude predicted increases in the expresser's perceptions of the communal strength of the relationship across time. In Study 3 (N = 75), participants were randomly assigned to an experimental condition, in which they expressed gratitude to a friend, or to one of three control conditions, in which they thought grateful thoughts about a friend, thought about daily activities, or had positive interactions with a friend. At the end of the study, perceived communal strength was higher among participants in the expression-of-gratitude condition than among those in all three control conditions. We discuss the theoretical and applied implications of these findings and suggest directions for future research.

Motivating change in relationships: can prayer increase forgiveness?

The objective of the current studies was to test whether praying for a relationship partner would increase willingness to forgive that partner. In Study 1 (N = 52), participants assigned to pray for their romantic partner reported greater willingness to forgive that partner than those who described their partner to an imagined parent. In Study 2 (N = 67), participants were assigned to pray for a friend, pray about any topic, or think positive thoughts about a friend every day for 4 weeks. Those who prayed for their friend reported greater forgiveness for their friend than did those in the other two conditions, even when we controlled for baseline forgiveness scores. Participants who prayed for their friend also increased in selfless concern during the 4 weeks, and this variable mediated the relationship between experimental condition and increased forgiveness. Together, these studies provide an enhanced understanding of the relationship benefits of praying for a partner and begin to identify potential mediators of the effect.

A prototype analysis of gratitude: varieties of gratitude experiences.

The present research tested the hypothesis that concepts of gratitude are prototypically organized and explored whether lay concepts of gratitude are broader than researchers' concepts of gratitude. In five studies, evidence was found that concepts of gratitude are indeed prototypically organized. In Study 1, participants listed features of gratitude. In Study 2, participants reliably rated the centrality of these features. In Studies 3a and 3b, participants perceived that a hypothetical other was experiencing more gratitude when they read a narrative containing central as opposed to peripheral features. In Study 4, participants remembered more central than peripheral features in gratitude narratives. In Study 5a, participants generated more central than peripheral features when they wrote narratives about a gratitude incident, and in Studies 5a and 5b, participants generated both more specific and more generalized types of gratitude in similar narratives. Throughout, evidence showed that lay conceptions of gratitude are broader than current research definitions.

Trading Later Rewards for Current Pleasure: Pornography Consumption and Delay Discounting.

Internet pornography is a multi-billion-dollar industry that has grown increasingly accessible. Delay discounting involves devaluing larger, later rewards in favor of smaller, more immediate rewards. The constant novelty and primacy of sexual stimuli as particularly strong natural rewards make Internet pornography a unique activator of the brain's reward system, thereby having implications for decision-making processes. Based on theoretical studies of evolutionary psychology and neuroeconomics, two studies tested the hypothesis that consuming Internet pornography would relate to higher rates of delay discounting. Study 1 used a longitudinal design. Participants completed a pornography use questionnaire and a delay discounting task at Time 1 and then again four weeks later. Participants reporting higher initial pornography use demonstrated a higher delay discounting rate at Time 2, controlling for initial delay discounting. Study 2 tested for causality with an experimental design. Participants were randomly assigned to abstain from either their favorite food or pornography for three weeks. Participants who abstained from pornography use demonstrated lower delay discounting than participants who abstained from their favorite food. The finding suggests that Internet pornography is a sexual reward that contributes to delay discounting differently than other natural rewards. Theoretical and clinical implications of these studies are highlighted.

Power and the pursuit of a partner's goals.

We investigated how power dynamics in close relationships influence the tendency to devote resources to the pursuit of goals valued by relationship partners, hypothesizing that low (vs. high) power in relationships would lead individuals to center their individual goal pursuit around the goals of their partners. We study 2 related phenomena: partner goal prioritization, whereby individuals pursue goals on behalf of their partners, and partner goal contagion, whereby individuals identify and adopt as their own the goals that their partner pursues. We tested our ideas in 5 studies that employed diverse research methods, including lab experiments and dyadic studies of romantic partners, and multiple types of dependent measures, including experience sampling reports, self-reported goal commitment, and behavioral goal pursuit in a variety of goal domains. Despite this methodological diversity, the studies provided clear and consistent evidence that individuals with low power in their relationships are especially likely to engage in both partner goal prioritization and partner goal contagion.

Explaining the relationship between religiousness and substance use: self-control matters.

Religiousness is reliably associated with lower substance use, but little research has examined whether self-control helps explain why religiousness predicts lower substance use. Building on prior theoretical work, our studies suggest that self-control mediates the relationship between religiousness and a variety of substance-use behaviors. Study 1 showed that daily prayer predicted lower alcohol use on subsequent days. In Study 2, religiousness related to lower alcohol use, which was mediated by self-control. Study 3 replicated this mediational pattern using a behavioral measure of self-control. Using a longitudinal design, Study 4 revealed that self-control mediated the relationship between religiousness and lower alcohol use 6 weeks later. Study 5 replicated this mediational pattern again and showed that it remained significant after controlling for trait mindfulness. Studies 6 and 7 replicated and extended these effects to both alcohol and various forms of drug use among community and cross-cultural adult samples. These findings offer novel evidence regarding the role of self-control in explaining why religiousness is associated with lower substance use.

Implicit theories of relationships and close relationship violence: does believing your relationship can grow relate to lower perpetration of violence?

People differ in what they think makes for a successful relationship, but it is unclear how these beliefs relate to the perpetration of violence. Four studies (N = 2,591) examined the relationship between growth beliefs and the perpetration of violence in close relationships. Specifically, the current work tested the hypothesis that growth beliefs mitigate against close relationship violence, possibly due to increased satisfaction with sacrificing one's own self-interest for the betterment of the relationship. Studies 1 and 2 provided cross-sectional and longitudinal evidence that growth beliefs predicted less perpetration of close relationship violence. Studies 3 and 4 showed that the relationship between growth beliefs and lower perpetration of violence was mediated by satisfaction with sacrifice within one's relationship. All effects of growth beliefs remained significant after controlling for destiny beliefs. Discussion centers on the importance of implicit theories of relationships for understanding the perpetration of violence in close relationships.

To belong is to matter: sense of belonging enhances meaning in life.

In four methodologically diverse studies (N = 644), we found correlational (Study 1), longitudinal (Study 2), and experimental (Studies 3 and 4) evidence that a sense of belonging predicts how meaningful life is perceived to be. In Study 1 (n = 126), we found a strong positive correlation between sense of belonging and meaningfulness. In Study 2 (n = 248), we found that initial levels of sense of belonging predicted perceived meaningfulness of life, obtained 3 weeks later. Furthermore, initial sense of belonging predicted independent evaluations of participants essays on meaning in life. In Studies 3 (n = 105) and 4 (n = 165), we primed participants with belongingness, social support, or social value and found that those primed with belongingness (Study 3) or who increased in belongingness (Study 4) reported the highest levels of perceived meaning. In Study 4, belonging mediated the relationship between experimental condition and meaning.

Putting the brakes on aggression toward a romantic partner: the inhibitory influence of relationship commitment.

Why do people behave aggressively toward romantic partners, and what can put the brakes on this aggression? Provocation robustly predicts aggression in both intimate and nonintimate relationships. Four methodologically diverse studies tested the hypothesis that provocation severity and relationship commitment interact to predict aggression toward one's romantic partner, with the aggression-promoting effects of provocation diminishing as relationship commitment increases. Across all four studies, commitment to one's romantic relationship inhibited aggression toward one's partner when individuals were severely (but not mildly) provoked. Study 4 tested the hypothesis that this Partner Provocation × Commitment interaction effect would be strong among individuals high in dispositional tendencies toward retaliation but weak (perhaps even nonexistent) among individuals low in such tendencies. Discussion emphasizes the importance of understanding instigating, impelling, and inhibiting processes in the perpetration of aggression toward intimate partners.

Repulsed by violence: disgust sensitivity buffers trait, behavioral, and daily aggression.

Many models of aggression include negatively valenced emotions as common elicitors of aggressive behavior. Yet, the motivational direction of these emotions is not taken into account. The current work explored whether sensitivity to a negative emotion associated with behavioral avoidance-disgust-will predict lower levels of aggression. Five studies tested the hypothesis that disgust sensitivity predicts less aggression. In Study 1 (N = 92), disgust sensitivity predicted less trait physical and verbal aggression. In Study 2 (N = 268), participants high in disgust sensitivity were less likely to behave aggressively towards a stranger on a reaction-time task. In Study 3 (N = 51), disgust sensitivity was associated with less intimate partner violence inclinations. Study 4 (N = 247) replicated this effect longitudinally. In Study 5 (N = 166), each domain of disgust (i.e., moral, sexual, and pathogen disgust) had a buffering effect on daily aggression when daily experiences activated those specific domains. These results highlight the usefulness of considering the motivational direction of an emotion when examining its influence on aggression.

Emotion differentiation moderates aggressive tendencies in angry people: A daily diary analysis.

Anger is commonly associated with aggression. Inefficient anger-coping strategies increase negative affect and deplete the regulatory resources needed to control aggressive impulses. Factors linked with better emotion regulation may then weaken the relationship between anger and aggression. The current work explored one factor associated with emotion regulation-differentiating one's emotions into discrete categories-that may buffer angry people from aggression. Three diary studies (N = 628) tested the hypothesis that emotion differentiation would weaken the relationship between anger and aggression. In Study 1, participants high in emotion differentiation reported less daily aggressive tendencies when angry, compared to low differentiators. In Study 2, compared to low differentiators, high differentiators reported less frequent provocation in daily life and less daily aggression in response to being provoked and feeling intense anger. Study 3 showed that high daily emotional control mediated the interactive effect of emotion differentiation and anger on aggression. These results highlight the importance of considering how angry people differentiate their emotions in predicting their aggressive responses to anger.

Expressing gratitude to a partner leads to more relationship maintenance behavior.

We proposed that expressing gratitude would increase positive perception of a relationship partner, thereby increasing comfort in expressing relationship concerns, which is a form of relationship maintenance. Study 1 (n = 159) showed a relationship between naturally occurring expressions of gratitude and comfort in voicing relationship concerns. Study 2 (n = 178) provided longitudinal evidence for direction of effects because Time 1 gratitude expression predicted Time 2 comfort in voicing relationship concerns, controlling for baseline comfort in voicing relationship concerns. Study 3 (n = 225) showed that expressing gratitude to a friend did increase voicing relationship concerns, compared with positive thought and neutral control conditions. In Study 4 (n = 74), we explored the mechanism through a longitudinal, experimental design and found that participants assigned to express gratitude reported higher comfort voicing concerns and more positive perception of partner than did control participants. Moreover, positive perception of partner mediated the relationship between condition and comfort in voicing relationship concerns.

So far away from one's partner, yet so close to romantic alternatives: avoidant attachment, interest in alternatives, and infidelity.

Temptation pervades modern social life, including the temptation to engage in infidelity. The present investigation examines one factor that may put individuals at a greater risk of being unfaithful to their partner: dispositional avoidant attachment style. The authors hypothesize that avoidantly attached people may be less resistant to temptations for infidelity due to lower levels of commitment in romantic relationships. This hypothesis was confirmed in 8 studies. People with high, vs. low, levels of dispositional avoidant attachment had more permissive attitudes toward infidelity (Study 1), showed attentional bias toward attractive alternative partners (Study 2), expressed greater daily interest in meeting alternatives to their current relationship partner (Study 5), perceived alternatives to their current relationship partner more positively (Study 6), and engaged in more infidelity over time (Studies 3, 4, 7, and 8). This effect was mediated by lower levels of commitment (Studies 5-8). Thus, avoidant attachment predicted a broad spectrum of responses indicative of interest in alternatives and propensity to engage in infidelity, which were mediated by low levels of commitment.

Does college-based relationship education decrease extradyadic involvement in relationships?

We used latent growth curve modeling to examine the effectiveness of a relationship education intervention (Relationship U, or RU) on rates of extradyadic involvement in a sample of 380 college students in committed romantic relationships. RU is designed to be integrated into existing college courses; it educates students about partner selection, making healthy relationship transitions, communication skills, and the potentially negative consequences of cheating in romantic relationships and how to prevent its occurrence. Participants who received the intervention reported trajectories of less extradyadic involvement over time relative to control participants. Being female was not associated with less extradyadic involvement at baseline, but it did predict less extradyadic involvement over time across both intervention and control conditions. Implications for dissemination of relationship education are discussed.

Faith and unfaithfulness: can praying for your partner reduce infidelity?

Because religion and/or spirituality is integral to the lives of a majority of the world population, we conducted 3 studies on the role of prayer in romantic relationships. Study 1 (N = 375) showed that prayer for the partner predicted lower levels of extradyadic romantic behavior over a 6-week period, over and beyond relationship satisfaction, and initial levels of extradyadic romantic behavior. In Study 2 (N = 83), we used an experimental design to show that participants assigned to pray for each day for 4 weeks engaged in lower levels of extradyadic romantic behavior during that time, compared with those who engaged in daily positive thoughts about the partner or a neutral activity. Perception of the relationship as sacred mediated the relation between experimentally manipulated prayer and later infidelity. Study 3 (N = 23) showed that objective observers rated participants who had been praying for their partner for 4 weeks as more committed to their romantic relationship than control participants. The implications of these results are then discussed.

Invocations and intoxication: does prayer decrease alcohol consumption?

Four methodologically diverse studies (N = 1,758) show that prayer frequency and alcohol consumption are negatively related. In Study 1 (n = 824), we used a cross-sectional design and found that higher prayer frequency was related to lower alcohol consumption and problematic drinking behavior. Study 2 (n = 702) used a longitudinal design and found that more frequent prayer at Time 1 predicted less alcohol consumption and problematic drinking behavior at Time 2, and this relationship held when controlling for baseline levels of drinking and prayer. In Study 3 (n = 117), we used an experimental design to test for a causal relationship between prayer frequency and alcohol consumption. Participants assigned to pray every day (either an undirected prayer or a prayer for a relationship partner) for 4 weeks drank about half as much alcohol at the conclusion of the study as control participants. Study 4 (n = 115) replicated the findings of Study 3, as prayer again reduced drinking by about half. These findings are discussed in terms of prayer as reducing drinking motives.

Bracing for the worst, but behaving the best: social anxiety, hostility, and behavioral aggression.

Social anxiety is marked by viewing social interactions as competitive, hypervigilance to signs of social threat, and avoidance of interactions that may result in social rejection. Therefore, social anxiety should relate to: (1) greater hostile feelings toward others, (2) heightened perceptions of hostility in others, and (3) relatively low levels of violence and aggression. To date, however, little is known about these relationships. In four independent non-clinical samples (total N=2643), we examined relationships between social anxiety, hostility, and aggression using a range of measures that included both self-report and behavioral assessments. In Study 1, social anxiety correlated positively with feeling hostile toward others. In Study 2, social anxiety correlated positively with hostile perceptions of others. In Study 3, social anxiety was related to less positive attitudes toward behaving violently toward one's relationship partner. In Study 4, social anxiety was related to less aggressive behavior, as indicated by less intense and prolonged noise blasts delivered to a fictitious opponent. Taken together, these four studies paint a picture of socially anxious people as bracing for the worst by feeling and perceiving hostility in the social environment, but behaving the best by refraining from aggression and violence.
