Neurolinguistics: A scientometric review

Abstract

This scientometric study aimed to map the knowledge domains of neurolinguistics, an interdisciplinary field of linguistics, to provide a comprehensive understanding of the development process and structural relationships of scientific knowledge in neuroscience. A total of 5,104 neurolinguistics documents published between 1913 and 2022 were analysed and visualized from three databases, Scopus, WOS, and Lens, using CiteSpace 5.8.R3 and VOSviewer 1.6.18. Knowledge production was mapped by country, university, journal, publisher, research field, and author, and examined using scientometric indicators, including co-citation networks, citation networks, sigma metrics, and clusters of topics. The identified clusters include discourse processing of flexible word order language language-ready brain, and language talent in cultural neurolinguistics; object knowledge of agrammatic aphasia; early experience of cerebral localization; language in autism spectrum disorder; and language evolution in relation to cognitive adequacy in language-ready brain. This study provides valuable insights into the field of neurolinguistics and offers a visual representation of the development process of scientific knowledge in neuroscience.
