Data and Materials for "Prosocial Behavior in Early Childhood: A Bibliometric and Science-Mapping Analysis of Literature Indexed in the Web of Science Core Collection (1985–2025)"

Version 2.0 corrects the normalization of author keywords by merging “prosocial behaviour” into “prosocial behavior.” The author-keyword co-occurrence network, cluster assignments, related tables, figures, and data files were updated accordingly. The source dataset, performance analysis, and document co-citation analysis remain unchanged.
