The collective communication model of terrorism (CCMT) proposes that understanding terrorists’ motives influences appraisal (threat perception and emotional well-being) and reaction to terrorism (intention to retaliate). Fischer et al. (2011) presented evidence from two experiments for the assumption that understanding motives of terrorism influences appraisal. The present preregistered experiment aimed to replicate their second experiment, validate the measures they used, and also test the second proposition of the CCMT. Ensuring sufficient power for multiple tests and the given effect size, we collected data from 188 participants. The findings by Fischer et al. (2011) were partly replicated, but the comparison of the original effect sizes and the effect sizes from the replication attempt does not provide convincing evidence for the hypothesis that understanding the motives for terrorism reduces the perceived threat or negative emotional impact of acts of terrorism. Correlations with other risk-perception measures call into question the validity of the items used to assess perceived threat. Results suggest that understanding the motives for terrorism may influence whether the targeted populations want to retaliate.

恐怖主义的集体传播模型（CCMT）提出，了解恐怖分子的动机会影响评估（威胁感知和情绪健康）和对恐怖主义的反应（报复意图）。菲舍尔等人。(2011) 提供了两个实验的证据，假设理解恐怖主义的动机会影响评估。目前预先注册的实验旨在复制他们的第二个实验，验证他们使用的措施，并测试 CCMT 的第二个命题。我们从 188 名参与者那里收集了数据，以确保有足够的能力进行多项测试和给定的效果大小。Fischer 等人的研究结果。（2011）被部分复制，但是，原始效果大小和复制尝试的效果大小的比较并没有为理解恐怖主义动机减少恐怖主义行为的感知威胁或负面情绪影响的假设提供令人信服的证据。与其他风险感知测量的相关性对用于评估感知威胁的项目的有效性提出了质疑。结果表明，了解恐怖主义的动机可能会影响目标人群是否想要进行报复。
