Dyslexia: A Bibliometric and Visualization Analysis

Abstract

Dyslexia is a disorder characterized by an impaired ability to understand written and printed words or phrases. Epidemiological longitudinal data show that dyslexia is highly prevalent, affecting 10–20% of the population regardless of gender. This study aims to provide a detailed overview of research status and development characteristics of dyslexia from types of articles, years, countries, institutions, journals, authors, author keywords, and highly cited papers. A total of 9,166 publications have been retrieved from the Social Sciences Citation Index (SSCI) and Science Citation Index Expanded (SCI-E) from 2000 to 2021. The United States of America, United Kingdom, and Germany were the top three most productive countries in terms of the number of publications. China, Israel, and Japan led the Asia research on dyslexia. University of Oxford had the most publications and won first place in terms of h-index. Dyslexia was the most productive journal in this field and Psychology was the most used subject category. Keywords analysis indicated that “developmental dyslexia,” “phonological awareness,” children and fMRI were still the main research topics. “Literacy,” “rapid automatized naming (RAN),” “assessment,” “intervention,” “meta-analysis,” “Chinese,” “executive function,” “morphological awareness,” “decoding,” “dyscalculia,” “EEG,” “Eye tracking,” “rhythm,” “bilingualism,” and “functional connectivity” might become the new research hotspots.

A 30-year bibliometric assessment and visualisation of emotion regulation research: applying network analysis and cluster analysis

“…The quantitative method of bibliometric analysis was strategically chosen for analysing scientific production in the field of emotion regulation. In recent times, bibliometric techniques have been widely adopted in various subfields of psychology as a means of assessing research performance, identifying research trends and themes, uncovering research hotspots and research gaps, as well as for tracing the structure, evolution and development of knowledge within the fields (Dong et al , 2022; Guo et al , 2022; Lin et al , 2022; Fei et al , 2022; Nie et al , 2022; Rong et al , 2022; Wu et al , 2022; Yang et al , 2022). With this viewpoint, this research aimed to explore the field of emotion regulation using bibliometric techniques, including performance measurement, science mapping and network analysis.…”

“…With almost 1.9 billion cited references and over 171 million records, the WoS database is globally recognized as the most reliable and comprehensive citation database, allowing users to track ideas across disciplines and time (Clarivate, 2022). This study preferred the WoS over Scopus because of the following reasons: A wide range of quality, high-impact scientific studies are hosted in WoS, making it a reliable and comprehensive resource for bibliometric analysis (Liu et al , 2018; Ekundayo and Okoh, 2018; Plusquellec and Denault, 2018; Nunen et al , 2017); Many scholars have earlier used WoS database specifically in various subfields of psychology for bibliometric analysis, for example, emotional intelligence (Dong et al , 2022); depression biomarker (Guo et al , 2022); cognitive behavioural therapy for cancer (Lin et al , 2022); delirium (Fei et al , 2022); epigenetic and childhood trauma (Nie et al , 2022); autism spectrum disorder (Rong et al , 2022); dyslexia (Wu et al , 2022); mindfulness and meditation (Wang et al , 2021); schizophrenia (Yang et al , 2022); alexithymia (Gaggero et al , 2020); and fMRI (Yeung, 2018). Thus, the WoS database is deemed more pertinent and selected as a data source for the bibliometric analysis in the field of emotion regulation. …”

“…This study analysed 162 publications indexed in the WoS Core Collection and found that the gut–brain axis and microbial-based therapies for schizophrenia are key research hotspots involving schizophrenia and the gut microbiota. Wu et al (2022) conducted a bibliometric analysis of dyslexia research published from 2000 to 2021. A total of 9,166 documents related to dyslexia were extracted from the Social Sciences Citation Index and Science Citation Index Expanded.…”

“…It allows us to disclose the evolutionary nuances of a particular discipline and identify research trends, hotspots and areas that require further exploration (Donthu et al , 2021). Recently, many scholars (Dong et al , 2022; Guo et al , 2022; Lin et al , 2022; Fei et al , 2022; Nie et al , 2022; Rong et al , 2022; Wu et al , 2022; Yang et al , 2022; Wang et al , 2021; Yeung, 2018) investigated various sub-disciplines of psychology through bibliometric techniques to assess research performance, uncover emerging research trends and themes, identify research gaps and trace the evolution and development of knowledge within the fields.…”

Antibiotic resistant bacteria: A bibliometric review of literature

“…Bibliometric analysis is an effective method for quantitatively assessing academic papers and can be used to investigate the evolution of certain fields, and the results can provide an overview of a certain field as well as research trends, hot topics, distribution of research power and future research directions (118)(119)(120)(121)(122). The advantage of bibliometric is that it is not limited by geography, allowing data to be collected by country in a particular area to analyze research globally (123). In addition, specific data analysis software can process the results of bibliometric analyses and present them in a more three-dimensional form (124)(125)(126)(127).…”
