ABSTRACT The Limited Capacity Model of Motivated Mediated Message Processing (LC4MP) aims to understand message processing dynamics. Despite 20 years of research, no meta-analysis has assessed LC4MP effects. We conducted a meta-analysis of the model to examine three theoretical research domains in the LC4MP: cognitive load, motivation, and memory. Results from 142 articles and 683 effects demonstrate that pooled effect sizes for research domain range from r = .314–.398. Effect sizes vary by measurement modality with self-report resulting in the largest pooled effect size, followed by behavioral, and finally psychophysiological measures. We did not detect evidence of publication bias. These findings offer meta-analytic support for LC4MP research domains and are discussed in terms of falsifiability, predictive and explanatory power.

有动机的中介消息处理的有限容量模型：元分析总结了二十年的研究

摘要 动机中介消息处理的有限容量模型 (LC4MP) 旨在了解消息处理动态。尽管进行了 20 年的研究，但没有荟萃分析评估过 LC4MP 的影响。我们对该模型进行了元分析，以检查 LC4MP 中的三个理论研究领域：认知负荷、动机和记忆。来自 142 篇文章和 683 个效应的结果表明，研究领域的合并效应大小范围为 r = .314–.398。影响大小因测量方式而异，自我报告导致最大的汇总效应大小，其次是行为，最后是心理生理学测量。我们没有发现发表偏倚的证据。这些发现为 LC4MP 研究领域提供了元分析支持，并在可证伪性、预测和解释能力方面进行了讨论。
