Replication studies of critical findings from the peer literature: An introduction

Despite its importance, replication has remained in the background of social development research. The aim of this special section was to elucidate and elevate the role of replication in peer relations research, examining its challenges and its utility for moving the field forward. To accomplish this aim, five sets of researchers undertook identifying an important finding from a widely cited article in the peer literature and tried to replicate its basic results using new data. As a group, the resulting five articles cover a broad range of topics, measures, and methods that are seen in peer research. Four of the five articles provide evidence of replication. This evidence was seen more for basic principles or processes observed in earlier studies than for exact or specific findings. In addition, the authors used varied approaches to replication, highlighting the need to embrace diverse methods when attempting to replicate complicated mechanisms of social development. It is argued that replication efforts should be aimed at identifying basic principles and processes of social development while clarifying the parameters that account for variability across studies in the specific findings.
