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.
