ABSTRACT
Anger is an unpleasant emotion that most people want to get rid of. Some anger management activities focus on decreasing arousal (e.g., deep breathing, mindfulness, meditation), whereas others focus on increasing arousal (e.g., hitting a bag, jogging, cycling). This meta-analytic review, based on 154 studies including 184 independent samples involving 10,189 participants, tested the effectiveness of both types of activities. The results indicated that arousal-decreasing activities decreased anger and aggression (g = -0.63, [-0.82, -0.43]), and the results were robust. Effects were stable over time for participants of different genders, races, ages, and cultures. Arousal-decreasing activities were effective in students and non-students, in criminal offenders and non-offenders, and in individuals with and without intellectual disabilities. Arousal-decreasing activities were effective regardless of how they were delivered (e.g., digital platforms, researchers, therapists), in both group and individual sessions, and in both field and laboratory settings. In contrast, arousal-increasing activities were ineffective overall (g = -0.02, [-0.13, 0.09]) and were heterogenous and complex. These findings do not support the ideas that venting anger or going for a run are effective anger management activities. A more effective approach for managing anger is "turning down the heat" or calming down by engaging in activities that decrease arousal.

Glowacki's work meshes well with our view of human nature as having evolved to use culture to improve survival and reproduction. Peace is a cultural achievement, requiring advances in social organization and control, including leaders who can implement policies to benefit the group, third-party mediation, and intergroup cooperation. Cultural advances shift intergroup interactions from negative-sum (war) to positive-sum (trade).

Gun violence in the USA is a documented public health crisis. Publicly accessible data from Twitter posts can be used to rapidly capture and describe the public's recent conversations about guns. Because these gun-related conversations change rapidly, it is important to provide regularly updated information on them. Twitter posts containing gun-related terms were obtained from January 1, 2022 to June 30, 2022. To understand topics of gun-related tweets (N = 449,492), topic modeling was performed with Top2Vec. Gun ownership control, concern about gun safety and its impact on children and schools, and the Second Amendment were major areas of the gun-related discourse on Twitter. Several identified topics in this study were a consequence of the study period, including "Discourse on Capitol Riots," and "Wartime and Military Use of Guns," with the latter topic containing conversations about the Russia-Ukraine War. Conversations around the influence of the National Rifle Association (NRA) on gun policies and pro-gun ownership perspectives were also part of the public discourse. The intersection between alcohol, substance use, and gun use was infrequently observed. Findings suggest that gun-related conversations in social media such as Twitter can inform public health researchers.

Firearm violence is now the leading cause of youth fatalities in the United States. This article outlines the various ways that entertainment media glorify the use of firearms and how this content can influence youth interest and use of guns. Social media are also increasingly serving as a source of risk for exposure to firearms. Counseling parents about the impact of media exposure to firearms on their children's health, and how to mitigate these risks, can be effective in promoting their children's health and safety.

To address a gap in the literature regarding the development of youth disclosure across the transition to adolescence, the current research uses a cohort-sequential approach to study youth disclosure from middle childhood through adolescence. Longitudinal data from three cohorts of parents were utilized (N = 1359; children at T1 were in grades 2 [M = 8.00 years, SD = 0.57 years, 45% female], 4 [M = 10.12 years, SD = 0.60 years, 45% female], and 9 [M = 15.19 years, SD = 0.57 years, 48% female]). Parents were assessed annually over a 3-year time period. The focal analyses explored contemporaneous associations between characteristics of the parent-youth relationship (specifically, parental rejection and parental consistent discipline) and youth disclosure after accounting for person-specific trajectories of disclosure. Associations of gender, age, and socioeconomic status with disclosure were also assessed. Regarding trajectories of youth disclosure, results indicate that youth disclose less information to their parents about their daily lives as they get older; this trend was consistent across gender and socioeconomic status. In terms of associations with youth disclosure, when parents provided more consistent discipline or engaged in less rejection of their child, youth disclosure increased, even after accounting for their own trajectory of disclosure across time. In addition, the association of consistent discipline with youth disclosure became stronger with increased youth age. Results are discussed in terms of implications for understanding youth autonomy development, and the dyadic and developmental impact of parenting behaviors over time.

Importance: Firearms are the leading cause of death for children in the US. It is therefore crucial to identify effective ways to reduce firearm injuries among children. Objective: To test the effectiveness of a gun safety video vs a car safety video on decreasing unsafe behaviors around real guns after exposure to a violent movie with vs without guns. Design, Setting, and Participants: Of 245 participants aged 8 to 12 years, 226 were tested (13 did not complete the laboratory portion, 4 had technical problems, and 2 did not respond to follow-up inquiries). Data were collected from February 2 to October 16, 2022. Participants were recruited via Facebook ads, ResearchMatch, and parent or guardian referrals. The study was conducted in 2 parts. Children watched a safety video at home 1 week before coming to the laboratory at The Ohio State University. Interventions: Pairs of children were randomly assigned to watch a 1-minute gun or car safety video at home. In the laboratory, they were randomly assigned to watch a 20-minute clip from a violent PG-rated movie with or without guns. Next, they played with games and toys for 20 minutes in another room that contained 2 disabled 9-mm handguns hidden in a file cabinet drawer. Sessions were videotaped via a hidden camera. Main Outcomes and Measures: Outcomes were whether children told an adult, touched a handgun, handled it, or pulled the trigger. Control variables were age, gender, race and ethnicity, trait aggressiveness, age-inappropriate media exposure, firearm attitude and interest, presence of firearms at home, and whether children had taken a firearm safety course. Results: Of 226 children (mean [SD] age, 9.99 [1.38] years; 113 [52.3%] male), 216 (95.6%) found a gun and were included in analyses. Those who saw the gun (vs car) safety video were more likely to tell an adult about the gun they found (38 of 112 [33.9%] vs 11 of 104 [10.6%]), were less likely to touch the gun (44 of 112 [39.3%] vs 70 of 104 [67.3%]), held the gun fewer seconds if they did touch it (mean [SD], 42.04 [121.46] vs 98.96 [195.10]), were less likely to pull the trigger at all (10 of 112 [8.9%] vs 31 of 104 [29.8%]), and pulled the trigger fewer times (mean [SD], 4.20 [20.17] vs 7.23 [15.75]). Being male, exposure to age-inappropriate movies, and gun interest were related to unsafe behavior. Prior completion of a firearm safety course, having guns at home, and negative gun attitudes were related to safe behavior. Conclusions: In this trial of children assigned to watch a gun or car safety video, watching a gun safety video reduced children's unsafe behavior around real guns. Children who had previously taken a gun safety course, had guns in the home, and had negative attitudes toward guns were less likely to engage in unsafe behavior around real guns. To encourage safe firearm behavior, children should be educated about gun safety and should not watch age-inappropriate media. Trial Registration: ClinicalTrials.gov Identifier: NCT05257837.

One of the oldest scientific theories of human aggression is the frustration-aggression hypothesis, advanced in 1939. Although this theory has received considerable empirical support and is alive and well today, its underlying mechanisms have not been adequately explored. In this article, we examine major findings and concepts from extant psychological research on hostile aggression and offer an integrative conception: aggression is a primordial means for establishing one's sense of significance and mattering, thus addressing a fundamental social-psychological need. Our functional portrayal of aggression as a means to significance yields four testable hypotheses: (1) frustration will elicit hostile aggression proportionately to the extent that the frustrated goal serves the individual's need for significance, (2) the impulse to aggress in response to significance loss will be enhanced in conditions that limit the individual's ability to reflect and engage in extensive information processing (that may bring up alternative, socially condoned means to significance), (3) significance-reducing frustration will elicit hostile aggression unless the impulse to aggress is substituted by a nonaggressive means of significance restoration, (4) apart from significance loss, an opportunity for significance gain can increase the impulse to aggress. These hypotheses are supported by extant data as well as novel research findings in real-world contexts. They have important implications for understanding human aggression and the conditions under which it is likely to be manifested and reduced.

Social psychology findings have fared poorly in multi-site replication attempts. This article considers and evaluates multiple factors that may contribute to such failures, other than the "crisis" assumption that most of the field's published research is so badly flawed that it should be dismissed wholesale. Low engagement by participants may reduce replicability of some findings (while not affecting certain others). Incentives differ between original researchers and replicators. If multi-site replications are indeed biased toward failure, this may have a damaging effect on the field's ability to build correct theories.

OBJECTIVE: Callousness has been identified as a key driver of aggressive and violent behavior from childhood into early adulthood. Although previous research has underscored the importance of the parenting environment in contributing to the development of youth callousness, findings have generally been confined to the between-individual level and have not examined bidirectionality. In the current study, we test whether aspects of parenting are associated with callousness from childhood to adolescence both between and within individuals, examine the temporal ordering of associations, and test whether these relations are moderated by gender or developmental stage. METHOD: Data came from a longitudinal study in which parents of 1,421 youth (52% girls; 62% White and 22% Black) from the second, fourth, and ninth grades were interviewed three times, with one year between consecutive interviews. RESULTS: A random-intercept cross-lagged panel model indicated that elevated youth callousness predicts subsequent increases in parental rejection and decreases in consistency of discipline. Findings were largely similar for boys and girls, but within-individual associations were generally stronger for 4th graders compared to the 2nd and 9th graders. CONCLUSIONS: Callousness and parenting practices and attitudes were related both at the between-individual and within-individual level. These results have implications for the etiology and treatment of children and adolescents who exhibit callousness.
ABSTRACT
Multisite (multilab/many-lab) replications have emerged as a popular way of verifying prior research findings, but their record in social psychology has prompted distrust of the field and a sense of crisis. We review all 36 multisite social-psychology replications (plus three articles reporting multiple ministudies). We start by assuming that both the original and the multisite replications were conducted in honest and diligent fashion, despite often yielding different conclusions. Four of the 36 (11%) were clearly successful in terms of providing significant support for the original hypothesis, and five others (14%) had mixed results. The remaining 27 (75%) were failures. Multiple explanations for the generally poor record of replications are considered, including the possibility that the original hypothesis was wrong; operational failure; low engagement of participants; and bias toward failure. The relevant evidence is assessed as well. There was evidence for each of the possibilities listed above, with low engagement emerging as a widespread problem (reflected in high rates of discarded data and weak manipulation checks). The few procedures with actual interpersonal interaction fared much better than others. We discuss implications in relation to manipulation checks, effect sizes, and impact on the field and offer recommendations for improving future multisite projects.

Mindfulness is a focused attention to and acceptance of present experiences. Although several reliable and valid multi-item measures of trait mindfulness exist, researchers may sometimes want a short and quick measure of mindfulness. In this project, we developed and validated the Single-Item Mindfulness Scale (SIMS) to assess trait mindfulness. We conducted eight studies involving 3,125 adult and adolescent participants. The studies consisted of cross-sectional, short longitudinal, and daily diary designs. We first developed the wording of the SIMS in Studies 1 and 2 and then examined the validity and reliability in Studies 3-8. The SIMS was found to be reliable and valid. It correlated with several multi-item measures of mindfulness at effect sizes in the medium to large range. It also correlated in expected ways with variables known to be related to existing multi-item measures of mindfulness such as self-compassion, anxiety, negative affect, positive affect, depression, neuroticism, empathy, prosocial behavior, and self-consciousness. Furthermore, it correlated positively with daily reports of mindfulness in a two-week diary study. Although existing multi-item trait mindfulness scales should be used, when possible, the SIMS is recommended in situations when time, question quantity, or researcher focus is constrained.

The Tangram Help/Hurt Task (THHT) allows participants to help another participant win a prize (by assigning them easy tangrams), to hurt another participant by preventing them from winning the prize (by assigning them difficult tangrams), or to do neither (by assigning them medium tangrams) in offline or online studies. Consistent with calls for continued evidence supporting psychological measurement, we conducted a meta-analytic review of the THHT that included 52 independent studies involving 11,060 participants. THHT scores were associated with helping and hurting outcomes in theoretically predicted ways. Results showed that THHT scores were not only associated with short-term (experimental manipulations, state measures) and long-term (trait measures) helping and hurting outcomes, but also with helping and harming intentions. We discuss the strengths and limitations of the THHT relative to other laboratory measures of prosocial behavior and aggression, discuss unanswered questions about the task, and offer suggestions for the best use of the task.
ABSTRACT
Past research finds that a majority of gun and non-gun owners support key gun safety policies, yet gun owners tend to underestimate other gun owners' support for these policies. We predicted that these misperceptions of support might lead gun owners to view non-gun owners as being less similar to themselves, which might undermine intergroup cooperation to promote gun safety policies and fuel intergroup animosity. Importantly, we also predicted that correcting these misperceptions would be an effective way to reduce intergroup division and enhance intergroup cooperation. We tested these predictions across two studies in which participants were randomly assigned to read information designed to correct misperceptions of gun owner support or to read other, control information. Across both studies, we find that correcting gun owners' misperceptions of gun owner support for gun safety policies leads to greater perceptions of identity overlap between gun and non-gun owners, greater willingness to work with each other to promote gun safety policies, and less negative affect towards each other. This suggests that correcting gun owner misperceptions of gun owners' support for gun safety policies might be an effective intervention to facilitate intergroup cooperation to promote these policies. Therefore, efforts to promote gun safety policies might benefit from educating gun owners about the degree of support for these policies that already exists among gun owners. Doing so might present a simple and cost-effective way to mobilize gun owners in support of these policies.

Women are often depicted as sex objects rather than as human beings in the media (e.g., magazines, television programs, films, and video games). Theoretically, media depictions of females as sex objects could lead to negative attitudes and even aggressive behavior toward them in the real world. Using the General Aggression Model (Anderson & Bushman, 2002) as a theoretical framework, this meta-analytic review synthesizes the literature on the effects of sexualized media (both violent and nonviolent) on aggression-related thoughts, attitudes, and behaviors. Our sample includes 166 independent studies involving 124,236 participants, which yielded 321 independent effects. Overall, the effects were "small" to "moderate" in size (r = .16 [.14-.18]). Significant correlations were found in experimental, cross-sectional, and longitudinal studies, indicating a triangulation of evidence. Effects were stronger for violent sexualized media (r = .25 [.19-.31]) than for nonviolent sexualized media (r = .15 [.13-.17]), although the effects of nonviolent sexualized media were still significant and nontrivial in size. Moreover, the effects of violent sexualized media on aggression were greater than the effects of violent non-sexualized media on aggression obtained in previous meta-analyses. Effects were similar for male and female participants, for college students and non-students, and for participants of all ages. The effects were also stable over time. Sensitivity analyses found that effects were not unduly influenced by publication bias and/or outliers. In summary, exposure to sexualized media content, especially in combination with violence, has negative effects on women, particularly on what people think about them and how aggressively they treat them.

This meta-analytic review examines the link between narcissism and aggression, and whether the link is stronger under provocation conditions. A total of 437 independent studies were located, which included 123,043 participants. Narcissism was related to both aggression (r = .26, [.24, .28]) and violence (r = .23, [.18, .27]). As expected, the narcissism-aggression link was stronger under provocation conditions (r = .29, [.23, .36]) than under no provocation conditions (r = .12, [.05, .18]), but was even significant in the absence of provocation. Both "normal" and "pathological" narcissism were related to aggression. All three dimensions of narcissism (i.e., entitlement, grandiose narcissism, vulnerable narcissism) were related to aggression. Narcissism was related to all forms of aggression (i.e., indirect, direct, displaced, physical, verbal, bullying), and to both functions of aggression (i.e., reactive, proactive). The relation between narcissism and aggression was significant for males and females, for people of all ages, for students and nonstudents, and for people from individualistic and collectivistic countries. Significant results were obtained in experimental, cross-sectional, and longitudinal studies, in published and unpublished studies, and in studies that assessed aggression using different types of measures (i.e., self-report, other-report, observation). Overall results were robust to publication bias and the presence of outliers. Theoretically, these results indicate that provocation is a key moderator of the link between narcissism and aggression. Individuals high in narcissism have "thin skins" and are prone to aggression when they are provoked. Practically, these results suggest that narcissism is an important risk factor for aggression and violence. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

In this study, we examine whether youth who are exposed to more weapons violence are subsequently more likely to behave violently with weapons. We use data collected with a 3-cohort, 4-wave, 10-year longitudinal study of 426 high-risk youth from Flint, Michigan, who were second, fourth, or ninth-graders in 2006-2007. The data were obtained from individual interviews with the youth, their parents, and their teachers, from archival school and criminal justice records, and from geo-coded criminal offense data. These data show that early exposure to weapons violence significantly correlates at modest levels with weapon carrying, weapon use or threats-to-use, arrests for weapons use, and criminally violent acts 10 years later. Multiple regression analyses, controlling for children's initial aggressiveness, intellectual achievement, and parents' income, education, and aggression, reveal statistically significant independent 10-year effects: (1) more early exposure to weapon use within the family predicts more using or threatening to use a gun; (2) more cumulative early violent video game playing predicts more gun using or threatening to use weapons, and normative beliefs that gun use is acceptable; (3) more cumulative early exposure to neighborhood gun violence predicts more arrests for a weapons crime; and (4) more cumulative early exposure to movie violence predicts more weapon carrying. We argue that youth who observe violence with weapons, whether in the family, among peers, or through the media or video games, are likely to be infected from exposure with a social-cognitive-emotional disease that increases their own risk of behaving violently with weapons later in life.

Importance: Despite broad public support for gun safety policies, minimal policy implementation has occurred. Objective: To investigate factors that encourage greater private support for and public action on gun safety policy. Design, Setting, and Participants: Three studies were conducted: a public opinion survey (Study 1) was conducted from January 8 to 22, 2019, and 2 experiments (Studies 2 and 3) were conducted from August 27 to October 17, 2019, and April 15 to 21, 2020, respectively. Adults living in the US were eligible to participate in Studies 1 and 3. Students 18 years and older participating in a research experience program were eligible to participate in Study 2. Study 1 was administered online by Ipsos, a market research company. A nationally representative sample of 1000 US adults was obtained from Ipsos' online KnowledgePanel, of whom 508 completed the public opinion survey. For Study 2, which was conducted in a university laboratory, 354 participants were recruited from a university research pool, all of whom completed the study. Study 3 was administered online by the market research company YouGov, which identified 727 US gun owners from its opt-in panel, from which it constructed a census-matched sample of 400 participants. Exposures: Participants read a statement about the 2018 Marjory Stoneman Douglas High School shooting. Content was manipulated as a 2 (corrective information vs no corrective information) × 2 (system changeable vs system not changeable) between-subjects factorial design with random assignment. The corrective information included polling data highlighting widespread support among gun owners for several gun safety policies. System changeable described gun safety policies passed by Florida's legislature. Main Outcomes and Measures: Main outcomes were support for gun safety policies and public disclosure of support. Results: The 3 studies included a total of 1262 participants (Study 1: 508 participants; weighted mean [SD] age, 47.7 [17.5] years; 261.9 women [51.6%]; 82.5 Hispanic [16.2%] and 60.3 Black [11.9%]; Study 2: 354 participants; mean [SD] age, 20.0 [2.3] years; 232 women [65.9%]; 100 Asian [28.3%] and 37 Black [10.5%]; Study 3: 400 participants; weighted mean [SD] age, 52.1 [16.4] years; 187.3 women [46.8%]; 295.5 White [73.9%], 44.5 Hispanic [11.1%], and 32.4 Black [8.1%]). Study 1 found that 63% to 91% of gun owners and 83% to 93% of non-gun owners supported key gun safety policies, yet both groups significantly underestimated gun owners' support for these policies by between 12% and 31%. Studies 2 and 3 found that exposure to corrective information was associated with a small increase in support for 2 gun safety policies of between 4% and 15%, both in terms of participants' privately held beliefs and the beliefs they would be willing to share publicly. Conclusions and Relevance: This survey study found that many US adults failed to recognize that most gun owners support key gun safety policies. Correcting this misperception was associated with greater private and public support for gun safety policy.

The study of aggressive driving is an important step in the reduction of (often fatal) crashes due to this behavior. However, even though various measures of aggressive driver behavior have been proposed, a more thorough examination of what the driving public perceives as aggressive driving behavior can be performed. A nationally representative sample of 198 American adults saw and rated the aggressiveness of various driving behaviors in videos. The videos were shown from a first-, second-, or third-person perspective. Some videos depicted close following, varying in speed and distance from the car ahead. Participants also saw illegal passing videos and collision or near collision videos. A number of variables that might influence judgments of aggressive driving were included as controls (i.e., trait anger, aggressive and prosocial driving attitudes, driving experience). Following other drivers closely was rated as aggressive, especially when viewed from a third-person perspective. Illegal passes were viewed as more aggressive than speeding. Faster speeds didn't increase aggressive ratings much, regardless of perspective. Aggressiveness ratings were especially high for acts that could be considered "road rage" (i.e., hitting or nearly hitting vehicles, cyclists, and pedestrians). People high in trait anger have a bias to view many driving behaviors as intentionally aggressive.

BACKGROUND: The prefrontal cortex is crucial for top-down regulation of aggression, but the neural underpinnings of aggression are still poorly understood. Past research showed the transcranial direct current stimulation (tDCS) over the ventrolateral prefrontal cortex (VLPFC) modulates aggression following exposure to risk factors for aggression (e.g., social exclusion, violent media). Although frustration is a key risk factor for aggression, no study to date has examined the modulatory role of tDCS on frustration-induced aggression. OBJECTIVES: By exploring the VLPFC involvement in frustration-aggression link, we tested the hypothesis that the anodal tDCS over right and left VLPFC modulates frustration-induced aggression. We also explored whether tDCS interacts with gender to influence frustration-induced aggression. METHODS: 90 healthy participants (45 men) were randomly assigned to receive anodal or sham tDCS over the right or left VLPFC before being frustrated by an accomplice. To increase reliability, several tasks were used to measure aggression. RESULTS: We found that anodal tDCS over the left VLPFC, compared to sham stimulation, increased aggression. Unexpectedly, no main effect was found following tDCS of right VLPFC. However, we also found a significant interaction between gender and tDCS, showing that males were more aggressive than females following sham stimulation, but females became as aggressive as males following active tDCS. CONCLUSION: Overall, these results shed light on the neural basis of frustration-induced aggression, providing further evidence for the involvement of VLPFC in modulating aggressive responses, and on gender differences in aggression. Future research should further investigate the role of stimulating the VLPFC on frustration-induced aggression.
