Replication is a research methodology designed to verify, consolidate, and advance knowledge and understanding within empirical fields of study. By repeating a study’s methodology (with or without change), a replication aims to better understand the nature and generalizability of a previous study’s findings. This chapter introduces readers to the replication research process, beginning with a description of what replication research is, what the most common types of replication research are, and why carrying out replication is important. Close attention is paid to the types of research questions that replication studies are designed to investigate. This is followed by an overview of replication in the field of ISLA, with links to studies and resources. In addition, specific guidelines are provided for carrying out and reporting replication studies. Recommendations for future replications in ISLA are suggested as well as ways in which researchers can integrate replication into future programs of research.
