Wielding a gun increases judgments of others as holding guns: a randomized controlled trial.

ABSTRACT: The gun embodiment effect is the consequence caused by wielding a gun on judgments of whether others are also holding a gun. This effect could be responsible for real-world instances when police officers shoot an unarmed person because of the misperception that the person had a gun. The gun embodiment effect is an instance of embodied cognition for which a person's tool-augmented body affects their judgments. The replication crisis in psychology has raised concern about embodied cognition effects in particular, and the issue of low statistical power applies to the original research on the gun embodiment effect. Thus, the first step was to conduct a high-powered replication. We found a significant gun embodiment effect in participants' reaction times and in their proportion of correct responses, but not in signal detection measures of bias, as had been originally reported. To help prevent the gun embodiment effect from leading to fatal encounters, it would be useful to know whether individuals with certain traits are less prone to the effect and whether certain kinds of experiences help alleviate the effect. With the new and reliable measure of the gun embodiment effect, we tested for moderation by individual differences related to prior gun experience, attitudes, personality, and factors related to emotion regulation and impulsivity. Despite the variety of these measures, there was little evidence for moderation. The results were more consistent with the idea of the gun embodiment effect being a universal, fixed effect, than being a flexible, malleable effect.

Project description:ImportanceFirearms 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.ObjectiveTo 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 participantsOf 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.InterventionsPairs 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 measuresOutcomes 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.ResultsOf 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.ConclusionsIn 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 registrationClinicalTrials.gov Identifier: NCT05257837.

Project description:ImportanceAmong resource-rich countries, the United States has the highest rate of child mortality by unintentional firearm use.ObjectiveTo test whether children's exposure to violent video games increases dangerous behavior around firearms.Design, setting, and participantsThis randomized clinical trial was set in a university laboratory and included pairs of children aged 8 to 12 years who knew each other. Of 313 participants who signed up, 250 were tested (2 arrived without partners, 61 did not arrive to participate). Of the 250 children tested, 8 were excluded (2 did not complete the study, 2 had participated in a related study, and 4 were outliers). Each child was paid $25. Data were collected July 1, 2017, to July 31, 2018.InterventionsIn a 3-group randomized design, pairs of children played or watched 1 of 3 versions of the game Minecraft for 20 minutes: (1) violent with guns, (2) violent with swords, or (3) nonviolent. The pairs of children were then placed in a different room and were told they could play with toys and games for 20 minutes. A cabinet in the room contained 2 hidden disabled handguns with counters for trigger pulls. Play sessions were videotaped.Main outcomes and measuresMain outcomes were touching a handgun, seconds spent holding a handgun, and number of trigger pulls (including at oneself or the partner). Control variables included sex, age, trait aggressiveness, exposure to violent media, attitudes toward guns, presence of firearms in the home, interest in firearms, and whether the child had taken a firearm safety course.ResultsOf 242 participants, 220 children (mean [SD] age, 9.9 [1.4] years; 129 [58.6%] boys) found a gun and were included in analysis. Among the 76 children who played the video game that included gun violence, 47 children (61.8%) touched a handgun. Among the 74 children who played the video game that included sword violence, 42 (56.8%) touched a handgun. Among the 70 children who played the nonviolent video game, 31 (44.3%) touched a handgun. Participants who played a violent version of the game were more likely to shoot at themselves or their partners than those who played a nonviolent game. Other risk factors for dangerous behavior around firearms included self-reported habitual exposure to violent media and trait aggressiveness. Self-reported exposure to violent media was positively associated with total trigger pulls (incidence rate ratio [IRR], 1.40; 95% CI, 1.00-1.98) and trigger pulls at oneself or one's partner (IRR, 1.88; 95% CI, 1.29-2.72). Trait aggression was positively associated with total trigger pulls (IRR, 13.52; 95% CI, 3.14-58.29), trigger pulls at oneself or one's partner (IRR, 25.69; 95% CI, 5.92-111.39), and time spent holding a handgun (IRR, 4.22; 95% CI, 1.62-11.02). One protective factor was having taken a firearm safety training course.Conclusions and relevanceExposure to violent video games increases children's dangerous behavior around firearms.Trial registrationClinicalTrials.gov identifier NCT03259139.

Project description:ImportanceMore US children die by accidental gun use than children in other developed countries. One factor that can influence children's interest in guns is exposure to media containing guns.ObjectiveTo test whether children who see a movie containing guns will handle a real gun longer and will pull the trigger more times than children who see the same movie not containing guns.Design, setting, and participantsOne hundred four children aged 8 to 12 years recruited through advertisements were randomly assigned in pairs to watch a 20-minute PG-rated movie containing or not containing guns in a university laboratory. Children then played with toys and games in a room for 20 minutes while being video recorded. A cabinet in the room contained a real (disabled) gun with a sensor counting trigger pulls. Recordings were coded for the time spent holding the gun and in aggressive play. Data were collected from July 15, 2015, through January 1, 2016, and analyzed using generalized estimating equations (Tweedie log-link for time spent holding the gun; Poisson log-link for pulling the trigger).Main outcomes and measuresThe 2 main outcomes were time spent holding the gun and the number of trigger pulls. Control variables included sex, age, trait aggressiveness, exposure to violent media, interest in guns, and number of guns at home.ResultsAmong the 104 study participants (62 boys [59.6%] and 42 girls [40.4%]; mean (SD) age, 9.9 [1.5] years), the adjusted median number of trigger pulls among children who saw the movie containing guns was 2.8 (interquartile range [IQR], 0.2-2.8) compared with 0.01 (IQR, 0.01-0.2) among children who saw the movie not containing guns (adjusted odds ratio, 22.3; 95% CI, 6.0-83.4; P < .001). The adjusted median number of seconds spent holding the gun among children who saw a movie containing guns was 53.1 (IQR, 35.5-53.1) compared with 11.1 (IQR, 10.7-16.7) among children who saw the movie not containing guns (adjusted odds ratio, 3.0; 95% CI, 0.9-9.9; P = .07). Qualitative analyses on 4 pairs from each condition found that children who saw the movie containing guns also played more aggressively and sometimes fired the gun at people (ie, self, partner, or passersby on street).Conclusions and relevanceChildren in the United States frequently have access to unsecured firearms and frequently consume media containing guns. This experiment shows that children who see movie characters use guns are more likely to use guns themselves.Trial registrationclinicaltrials.gov Identifier NCT03220412.

Project description:Many studies suggest that preschoolers initially privilege outcome over intention in their moral judgments. The present findings reveal that, in contrast, even younger preschoolers can privilege intentions when evaluating characters who successfully or unsuccessfully help or hinder a third party in achieving its goal. Following a live-action puppet show originally created for infant populations, children made a forced-choice social judgment (which puppet was liked) and two forced-choice moral judgments (which puppet was nicer, which puppet should be punished), and were asked to explain their punishment allocations. In two experiments (N = 195), 3- and 4-year-olds evaluated characters with distinct intentions to help or to hinder who were associated with either positive or negative outcomes. Both ages judged characters with more positive intentions as nicer, and allocated punishment to characters with more negative intentions; neither of these tendencies depended on the outcomes the characters were associated with. Three-year-olds' responses were somewhat less consistent than were 4-year-olds', in that 3-year-olds' judgments were disrupted by ambiguous harmful intent. Notably, children's social judgments were less consistent than their moral judgments. In a third and final experiment (N = 100), children evaluated characters with the same intention but who were associated with different outcomes. Children showed inconsistent responding across age and outcome valence, but only 4-year-olds evaluating two characters with positive intentions reliably responded based on outcome. When providing informative responses in all three studies, children most frequently explained their punishment allocations by appealing to the puppet's (attempted) hindering action or failure to help. These findings raise questions as to what underlies different patterns of response across studies in the literature, and suggests that observing live interactions may facilitate young children's intention-based moral judgments.
