Area of Science:

• Psychology
• Social Psychology
• Behavioral Science

Background:

• The Taylor Aggression Paradigm (TAP) is a standard tool for assessing reactive aggression.
• Existing TAP versions lack real-time interaction, limiting ecological validity in familiar relationships.

Purpose of the Study:

• To introduce and evaluate the interactive Taylor Aggression Paradigm (iTAP) for studying reactive aggression.
• To investigate reactive aggression dynamics within high-familiarity dyads, specifically sibling pairs.
• To explore situational and personal variables influencing aggression in an interactive setting.

Main Methods:

• A quasi-experimental study using the iTAP with 28 adult sibling pairs (N=56).
• Participants engaged in 60 trials with simulated provocations and real-time opponents.
• Data collected on aggression levels, trial outcomes, state anger, and personal variables.

Main Results:

• Siblings exhibited a 'tit-for-tat' strategy, with aggression peaking during provocation and declining post-interaction, suggesting co-regulation.
• Situational variables (trial outcome) and state anger positively correlated with aggression; personal variables did not.
• No gender differences were observed, though trends suggested higher initial aggression in brother pairs and greater responsiveness in sister pairs.
• Subgroups with distinct aggression patterns were identified, linked to motivations and emotional states.

Conclusions:

• The iTAP is a promising tool for studying reciprocal aggressive behavior in interactive contexts.
• The interactive nature of iTAP enhances ecological validity, complementing standard TAP versions.
• Findings highlight the significant role of situational factors and relationship familiarity in modulating reactive aggression.
