RWTH Aachen University Reports Findings in Psychology (A quasi-experimental study in sibling dyads: differential provocation-aggression patterns in the interactive taylor aggression paradigm).

A report from RWTH Aachen University in Germany discusses a study on provocation-induced reactive aggression in sibling pairs using an interactive version of the Taylor Aggression Paradigm (TAP). The study involved 28 healthy same-sex adult sibling pairs competing against each other in the iTAP, which included simulated provocation trials. The results showed that siblings employed a "tit-for-tat" strategy in response to provocation, with aggression increasing during manipulated trials and declining in the final block. The study also found no gender differences in aggression dynamics but identified subgroups of sibling pairs with distinct provocation-aggression patterns. The researchers concluded that the interactive context of the iTAP introduced ecological validity and complemented the standard versions of the TAP. [Extracted from the article]
