Proactive vs. Reactive Aggression Within Two Modified Versions of the Taylor Aggression Paradigm

Area of Science:

• Psychology
• Neuroscience
• Behavioral Science

Background:

• Reactive aggression, often measured by the Taylor Aggression Paradigm (TAP), follows provocation in competitive settings.
• Aggression can also be goal-directed and unprovoked, termed proactive aggression.
• Existing paradigms primarily focus on reactive aggression, necessitating new methods to study proactive aggression.

Purpose of the Study:

• To introduce and validate a novel paradigm, the proactive Taylor Aggression Paradigm (pTAP), for measuring proactive aggression.
• To investigate the relationship between proactive aggression, reactive aggression, selfishness, gender, and physiological arousal (skin conductance responses - SCRs).
• To compare the characteristics of proactive and reactive aggression within a competitive context.

Main Methods:

• Sixty-seven participants competed in two modified TAP versions: pTAP (participant-initiated aggression) and rTAP (opponent-initiated provocation).
• Aggression was measured by blurriness levels set by the participant.
• Skin conductance responses (SCRs) were recorded to assess physiological arousal.

Main Results:

• Proactive aggression positively correlated with selfishness.
• Proactive aggression was associated with decreased SCRs, particularly in males, while females showed increased SCRs.
• Reactive aggression increased with provocation and loss, with females showing greater sensitivity to provocation than males.

Conclusions:

• Proactive and reactive aggression, though intercorrelated and driven by selfishness, are distinct in their relationship with gender and physiological arousal.
• Proactive aggression is linked to lower arousal, especially in males, whereas females exhibit higher arousal with increased proactive aggression.
• Reactive aggression is highly sensitive to provocation, with females demonstrating a stronger response.
