Summary
Road rage can stem from earlier frustrations. This study shows that anger from traffic delays impacts subsequent driving behavior, leading to riskier decisions even in non-provoking situations.
Area of Science:
- Psychology
- Traffic Psychology
- Behavioral Science
Background:
- Road rage and aggression can appear unprovoked.
- The link between prior anger-inducing events and current driving behavior is unclear.
Purpose of the Study:
- To investigate if anger provoked by traffic conditions influences subsequent driving behavior.
- To determine if negative affect and aggressive driving persist in non-provocative driving scenarios.
Main Methods:
- Ninety-six drivers participated in two simulated urban drives.
- The first drive involved enforced slow driving due to traffic, inducing anger.
- Mood, anger, arousal (heart rate), and driving behavior (speed, lane position, collisions) were measured.
Main Results:
- Drivers experiencing enforced slow driving showed increased anger, worsened mood, and poorer driving behavior compared to controls.
- Behavioral changes, including speed and lane positioning, persisted into a subsequent, non-provocative drive.
- Previously impeded drivers exhibited less caution and more dangerous overtaking maneuvers.
Conclusions:
- Anger provoked by external circumstances can lead to dangerous driving behavior.
- Driving behavior changes can carry over to situations unrelated to the initial provocation.
- Understanding the roots of anger is crucial for addressing aggressive driving.

01:41Social Traps
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned more cows, the larger...
01:13Nonconscious Mimicry
Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.
01:04Social Facilitation
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.
01:20Conformity
Conformity is the change in a person’s behavior to go along with the group, even if that person does not agree with the group.
01:25The Anchoring-and-Adjustment Heuristic
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the $2,000...
02:10Social Scripts
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter), the opening...
