What is the purpose of this trial?

This trial aims to explore ways to reduce aggressive driving, a major cause of traffic accidents. Researchers will examine various factors, such as music, video games, and bumper stickers, to determine their influence on driving behavior. Each study within the trial will focus on a different potential trigger or solution for aggressive driving. Adults in Central Ohio with a valid driver's license and no motion sickness who relate to specific scenarios, like playing video games or exposure to political messaging, might be a good fit. As an unphased trial, this study offers participants the chance to contribute to innovative research that could lead to safer driving environments.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

A previous study showed that different signals can affect aggressive driving. For example, studies indicate that drinking alcohol is linked to more aggressive driving and severe road rage. However, the study does not mention specific safety concerns about alcohol signals in a controlled setting.

Research on bumper stickers shows they can increase road rage, especially if they are political. However, the studies do not report any specific safety risks from just having bumper stickers in a controlled environment.

Music can affect driving behavior, with loud or medium volume music leading to faster driving. This suggests changes in behavior rather than direct safety risks.

Roadside plants might help reduce driver aggression by lowering stress and frustration, but there are no specific safety issues linked to them.

Regarding video games, playing violent racing games can lead to more aggressive driving, but studies focus on behavior changes rather than safety concerns in a test setting.

Videos of road rage may show real-world aggression, but they do not mention any safety risks related to watching such videos in an experimental context.

Overall, these factors are linked to changes in driving behavior. They don’t show direct safety problems for participants in controlled trials. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about these interventions for aggressive driving because they explore novel environmental and psychological factors that might influence driver behavior. Unlike traditional treatments which often focus on punitive measures or driver education programs, these interventions investigate how elements like roadside vegetation, music, video games, and bumper stickers can impact aggression levels. For instance, political and racial bumper stickers may provoke reactions based on personal beliefs, while music can alter mood and arousal through its lyrics and tempo. Additionally, the presence of alcohol-related cues or nature scenery aims to reveal subconscious influences on aggression. These innovative approaches could lead to more effective strategies to reduce aggressive driving by addressing underlying psychological triggers.

What evidence suggests that this trial's treatments could be effective for aggressive driving?

This trial explores various interventions for aggressive driving. Experiment 5 exposes participants to alcohol-related cues, such as a 12-pack of beer or sparkling water on the passenger seat, to test their impact on aggressive driving. Experiment 4 examines how political bumper stickers affect aggressive driving among Republicans and Democrats. Experiment 6 investigates the influence of music with aggressive versus prosocial lyrics and different tempos on driving behavior. Experiment 7 tests whether roadside vegetation can reduce aggression in frustrated drivers. Lastly, Experiment 2 assesses the impact of playing violent versus nonviolent video games on driving aggression. Each experiment aims to understand how these factors might influence aggressive driving behaviors. ^{1 3 4 6 7}

• Videos

Trial Overview The study tests how different factors like roadside vegetation, video games, videos, bumper stickers, alcohol-related cues, and music influence aggressive driving behavior using a driving simulation.

How Is the Trial Designed?

Group I: Experiment 7 Experimental Treatment 1 Intervention

Experiment 7 tests whether roadside vegetation can reduce aggression in frustrated drivers. After giving their consent, participants (N=90, n=30 per group) will complete the personality variables (see Experiment 1). Next, they will complete the Enjoyment of Nature Scale (Cheng \& Moore, 2012), which contains 7 items (e.g., "I like to see wild flowers in nature" and "Being in the natural environment makes me feel peaceful"; 1=strongly disagree to 5= strongly disagree; Cronbach =.87). Next, participants will be randomly assigned to one of three driving scenarios: (1) roadside vegetation, (2) trash, or (3) control (no roadside vegetation / no trash). After participants complete the driving scenario, they will complete measures of state and hostile appraisals, and will be debriefed.

Group II: Experiment 6 Experimental Treatment 1 Intervention

Experiment 6 will test the effects of music with aggressive versus prosocial lyrics on aggressive driving. The tempo of the music will also be manipulated because it might influence arousal levels. After giving their consent, participants (N=150, n=30 per group) will complete the personal variables (see Experiment 1). Music will be played over the car's sound system. Participants will be randomly assigned to one of five conditions: (1) violent lyrics / upbeat tempo, (2) violent lyrics / calm tempo, (3) prosocial lyrics / upbeat tempo, (4) prosocial lyrics / calm tempo, or (5) no music control. After participants complete the driving scenario, they will complete measures of state and hostile appraisals, and will be debriefed.

Group III: Experiment 5 Experimental Treatment 1 Intervention

Experiment 5 tests whether alcohol-related cues can increase aggressive driving. After giving their consent, participants (N=40) will complete the personal variables (see Experiment 1). Next, participants will be randomly assigned to one of two conditions: (1) 12-pack of beer on passenger seat, or (2) 12-pack of sparkling water on passenger seat. Participants will be told that the object on the seat is part of a different experiment that the other experimenter forgot to clean up, which they should ignore it. After participants complete the driving scenario, they will complete measures of state and hostile appraisals, and will be debriefed.

Group IV: Experiment 4 Experimental Treatment 1 Intervention

Experiment 4 tests the effects of political bumper stickers on aggressive driving in Republicans versus Democrats. After giving their consent, participants (N=120; n=60 Republicans, n=60 Democrats) will complete the personal variables (see Experiment 1). Some cars in the driving scenario will contain bumper stickers. Experiment 4 has four conditions: (1) Republicans / "Donald Trump for President 2016" stickers, (2) Republicans / "Hillary Clinton for President 2016" stickers, (3) Democrats / "Donald Trump for President 2016" stickers, (4) Democrats / "Hillary Clinton for President 2016" stickers. After participants complete the driving scenario, they will complete measures of state and hostile appraisals, and will report their attitudes toward Trump and Clinton. A debriefing will follow.

Group V: Experiment 3 Experimental Treatment 1 Intervention

Experiment 3 tests the effects of racial bumper stickers on black and white participants. After giving their consent, participants (N=120; n=60 black, n=60 white) will complete the personal variables (see Experiment 1), the race IAT, and report their political party. Some cars in the driving scenario will contain bumper stickers. Experiment 3 contains four conditions: (1) white participants / "All Lives Matter" stickers, (2) black participants / "All Lives Matter" stickers, (3) white participants / "Black Lives Matter" stickers, (4) black participants / "Black Lives Matter" stickers. After participants complete the driving scenario, they will complete measures of state and hostile appraisals, and will report their attitudes toward the #BLM and #ALM movements. A debriefing will follow.

Group VI: Experiment 2 Experimental Treatment 1 Intervention

Experiment 2 tests whether participants actually drive more aggressively after a playing a violent or nonviolent racing video game. After giving their consent, participants (N=60, n=30 each group) will complete the same personal variables as in Experiment 1, and will report the video games they play. Next, participants will be randomly assigned to play one of two types of video games for 20 minutes: (1) violent racing video game, (2) nonviolent racing game, or (3) a neutral game. After participants complete the driving scenario, participants will complete measures of state and hostile appraisals. A debriefing will follow.

Group VII: Experiment 1 Experimental Treatment 1 Intervention

The purpose of Experiment 1 is to develop a standardized measure of aggressive driving for driver simulation experiments. After giving their consent, participants (N=200) will complete several personal variables (i.e., gender, age, driving experience, driving frequency, trait anger, self-reported aggressive and prosocial driving). Next, participants will watch several short videos of aggressive driving (e.g., speeding, tailgating, driving on shoulder), and road rage (e.g., hitting another vehicle or pedestrian). Participants will indicate whether the driver's behavior was aggressive (yes, no), and will rate how aggressive it was on an 11-point scale (0=not at all aggressive to 10=extremely aggressive). A debriefing will follow.

In a study of 628 individuals with untreated alcohol use problems, increased participation in Alcoholics Anonymous (AA) and outpatient treatment during the first year was linked to a significant reduction in driving while intoxicated (DWI) incidents at both 1-year and 16-year follow-ups.

Improvements in personal functioning and coping skills were found to mediate the relationship between AA participation and reduced DWI occurrences, suggesting that ongoing support from AA can lead to better psychological outcomes and lower DWI rates.

In a study of 407 injured emergency department patients with harmful alcohol use, neither involvement in a motor vehicle crash (MVC) nor readiness to change drinking and driving behaviors significantly predicted improvements in impaired driving behaviors over time.

Despite the lack of predictive factors for behavior change, the study highlights that patients are generally open to engaging in interventions aimed at reducing risky behaviors related to alcohol use.

Drivers with higher aggressive driving traits exhibited more aggressive behaviors, such as failing to yield to pedestrians and driving closer to them, especially when provoked by aggressive stimuli like honking.

Repeated exposure to aggressive situations led to an accumulation of aggressive driving behaviors, indicating that both individual traits and environmental factors significantly impact traffic safety at pedestrian crossings.
