Physiological Synchrony Evoked by Attentional Engagement: A Systematic Review Based on CiteSpace

Abstract

This study uses CiteSpace, a bibliometric and visualization-analysis tool, to present a systematic analysis of literature in the Web of Science database on physiological-synchrony evoked by attentional engagement. It reviews the publication timeframe, authorship, keywords, and leading institutions and regions, along with burst terms and highly cited papers that represent key research trends and hotspots. The key findings are discussed below. While there is a general rising trend in the number of publications on this subject, the distribution of authors is fragmented. The University of California and City University of New York in the U.S. are the two most productive institutional systems. The United States, Germany, and China are the three most productive countries. In research hotspots, investigators tend to focus on brain-to-brain synchrony, eye-movement synchrony, heart-rate synchronization, and other physiological indicators. Future research may continue to investigate fields related to the synchronization of brain and eye movements.
