About Our Research

We conduct applied psychological research on dysfunctional anger, aggression, and clinical traffic psychology. Each of these domains is described in more detail below.


Anger is a common emotion that can become problematic when it is experienced too intensely, too frequently, or is expressed in destructive ways. Problem anger is associated with a number of adverse health and mental health problems (e.g., coronary heart disease, hypertension, loss of social support, domestic violence, occupational burnout, substance abuse, etc.). Although it is becoming increasingly common for people to seek help for dysfunctional anger, many clinicians are unprepared when it comes to working with angry clients. In part, this is likely due to the paucity of research on anger as compared with emotional problems such as depression or anxiety. This can pose a challenge, but it also means that now is an ideal time to advance our understanding of anger and expand what we know about the prevention and treatment of anger problems.

Examples of our work on anger include:
  • the role of anger expression in binge eating
  • the identification of individuals at risk for developing problems with anger and the development of prevention and early intervention strategies
  • assessing attitudes toward seeking help for anger problems
  • developing and evaluating innovative approaches to anger management
  • studies of the psychosocial costs of problem anger (e.g., loss of social support, loneliness, burnout)


Overt forms of aggressive behavior (i.e., physical and verbal aggression) have received considerable attention in the literature; however, surprisingly little is known about relational aggression, a form of aggression aimed at harming victims' relationships, reputation, and/or sense of belonging.

Much of our recent work on aggression has focused on relational aggression in the peer and dating relationships of college students. Examples include:
  • the Five Factor model of personality, rejection sensitivity, and social anxiety as predictors of relational aggression
  • parenting style and parental psychological control in relational aggression and prosocial behavior of emerging adults
  • the identification of adverse correlates of relational aggression and victimization among college students
  • adult attachment and relational aggression
  • relational aggression and dating violence in college students' romantic relationships
  • relational aggression and the Dark Triad of personality (e.g., psychopathy, narcissism, and Machiavellianism)
We have also just started to explore electronic aggression (also known as cyber aggression) and expect to continue this line of work, as initial findings have been encouraging.

Clinical Traffic Psychology

aggressive driving
Despite improvements in automobile and roadway safety, motor vehicle accidents remain a serious public health problem. Traffic psychology is concerned with the investigation of driver behavior and the psychological factors associated with it. For example, an impressive body of research demonstrates the importance of driver personality in contributing to a variety of risky driving behaviors (e.g., speeding, failure to use safety belts, driving while distracted, etc.) and accident-related outcomes.

Most of our traffic psychology research overlaps with our work on anger and aggression, as we tend to focus on driving anger and aggressive driving. However, we have also examined constructs such as spirituality, forgiveness, boredom proneness, sensation seeking, and impulsivity in the broader context of driving behavior and accident-related outcomes. Of particular interest is the quest to identify personality factors which would permit the identification of high-risk drivers and inform driver's education and traffic safety efforts.
Anger and Traffic Psychology Lab
The Anger and Traffic Psychology Lab is directed by Dr. Eric R. Dahlen in the Department of Psychology at the University of Southern Mississippi. Doctoral and master's students in the Counseling Psychology graduate programs and undergraduate students at the University of Southern Mississippi study anger, aggression, traffic psychology, and related areas.
