Conceptual Replications – Guidelines for implementation and factors influencing replicability across different fields in psychology

研究特征的变化，而不是精确的复制，是理解效应异质性的核心方面。我们专注于概念复制（CR）中研究特征的系统性变化，并依赖于最近开发的因果复制框架（CRF，Steiner & Wong，2018; Steiner，Wong，& Anglin，2019）。CRF使用因果理论来定义和设计重复研究。具体而言，CRF允许因果识别影响可复制性的因素，并描述了如何使用研究设计和分析方法来系统地研究效应异质性。到目前为止，该框架已成功地应用于CR在教育研究中。然而，研究的特点以及如何在重复研究中保持恒定在不同的学科，需要各自的设计和分析方法。我们的目标是使通用报告格式适用于更广泛的学科。我们建立在以前的工作，系统地设计了几个CR与CRF在不同的心理学科。我们专注于社会和认知心理学，代表不同的挑战复制，并比较这些现有的研究在教育心理学。此外，我们详细介绍了SPP内可能的合作，以实现CRF更广泛的跨学科应用。因此，在我们的项目中，我们将开发CRF在各个学科中的应用方法，确定不同学科内和跨学科引起异质性的因素，并得出CR研究的指南。

Variation of study characteristics, instead of exact replication, is a core aspect for understanding effect heterogeneity. We focus on systematic variation of study characteristics in conceptual replications (CR) and rely on the recently developed causal replication framework (CRF, Steiner & Wong, 2018; Steiner, Wong, & Anglin, 2019). The CRF uses causal theory for defining and designing replication studies. Specifically, the CRF allows for causally identifying factors that impact replicability, and describes how research designs and analyses methods can be used for systematically studying effect heterogeneity. So far, the framework has been successfully applied for CR in educational research. However, characteristics of studies and how they can be kept constant across replications differs across disciplines, calling for respective designs and analyses methods. We aim to make the CRF applicable to a broader range of disciplines. We build on the previous work and systematically design several CRs with the CRF in different psychological disciplines. We focus on social and cognitive psychology, representing different challenges for replication, and compare these to existing studies in educational psychology. Furthermore, we detail possible cooperations within the SPP for an even broader interdisciplinary application of the CRF. As such, in our project we will develop approaches for the application of the CRF in various disciplines, identify factors that cause effect heterogeneity within and across different disciplines, and derive guidelines for CR studies.
