Reactive aggression, unlike proactive aggression, is linked to a tendency to approach threatening stimuli. This suggests hyper-reactivity in the approach-related reward system for reactive aggression.
Area of Science:
- Psychology
- Neuroscience
- Behavioral Science
Background:
- Aggression is broadly categorized into reactive (impulsive, anger-driven) and proactive (goal-directed, controlled) forms.
- Behavioral approach and avoidance tendencies are fundamental motivational systems influencing responses to stimuli.
Purpose of the Study:
- To investigate the association between behavioral approach/avoidance tendencies and reactive versus proactive aggression.
- To differentiate the correlates of reactive and proactive aggression.
Main Methods:
- A sample of 118 patients and healthy controls completed self-report measures for reactive and proactive aggression.
- Participants performed an Approach Avoidance Task using joystick movements in response to various visual stimuli (attack-related, emotional, neutral).
- Analyses controlled for personality disorder pathology, gender, and age.
Main Results:
- Reactive aggression, but not proactive aggression, was significantly associated with a behavioral tendency to approach attack-related scenes and positive stimuli.
- This finding suggests a hyper-reactive approach-related reward system in individuals with reactive aggression.
Conclusions:
- Reactive and proactive aggression have distinct behavioral correlates and potential precursors.
- The findings contribute to understanding the neurobehavioral underpinnings of different aggression subtypes.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
