Social anxiety disorder (SAD) is a common but often overlooked mental disorder. Its traditional diagnosis combines the assessment of cognitive symptoms wit

Objective: The aim of this study was to analyze the research hotspots and frontiers in the field of autistic traits (AT) between 1997 and 2024.Methods: The Web of Science Core Collection (WOSCC) is used as a data source in the study, analyzing 1,044 academic articles on AT published between 1997 and 2024. The included articles were visually analyzed using CiteSpace 6.2.R4 software, which is used to map keywords and core literature related to AT and to analyze research progress and emerging hotspots in the fieldResults: A total of 1,044 articles have been included in the analysis, and the total number of articles has demonstrated an upward trajectory. The nations of England, the USA, and Australia are at the vanguard of this body of literature. With regard to research institutions, the University of London has attracted considerable attention as a result of its substantial contributions to the field of AT. The most relevant research is published in the Journal of Autism and Developmental Disorders.Conclusion: The scope of AT research has expanded considerably, encompassing psychology, education, and other disciplines. The research dimensions extend beyond behavioral, genetic, cognitive, and neural aspects to include environmental and hormonal factors. Furthermore, the study population has evolved from twins and the general population to focus on specific groups, such as individuals with psychiatric disorders. This broadening of focus has led to a significant increase in AT research in recent years. In sum, this study provides a comprehensive perspective that can inform and guide further in-depth research on AT.

This study aimed to compare the development and sensory channel feedback effects in number line estimation between children in grades 2 and 4 through two experiments, using both bounded number line estimation (BNLE) tasks and unbounded number line estimation (UNLE) tasks, respectively. Both Experiment 1 and Experiment 2 employed a mixed design of 2 (Grade: Grade 2, Grade 4) × 3 (Feedback Channel: visual feedback, auditory feedback, audio-visual feedback) × 2 (Scale: small, 0–100; large, 0–1000). Grade and feedback channel were between-subjects factors, while scale was a within-subjects factor. The results showed that in the BNLE tasks, children in both grades demonstrate the ability to estimate numbers within the linear representation stage, with grade 2 estimating numbers on the range of 0–100, while grade 4 extends this to the range of 0–1000. However, children in grade 2 are still undergoing the transformation from logarithmic-linear representation to the range of 0–1000 in their number estimation. In the UNLE tasks, grade 4 children showed greater linear model explanatory power within the range of 0–10 and no significant difference in the range of 10–30. Grade 2 children lacked significant linear or logarithmic representation characteristics, suggesting a potential transition phase. Auditory feedback enhanced BNLE task performance, while visual feedback improved UNLE task performance. The findings indicate that primary school children tend to shift from logarithmic to linear representation in both tasks, with higher BNLE task accuracy. Feedback proves beneficial in enhancing estimation accuracy in both types of NLE tasks, and distinctive feedback channel effects emerge in BNLE and UNLE tasks due to the varying strategies employed by children in each task.

Objectives: To conduct a comprehensive review of the literature pertaining to the broader autism phenotype, the paper endeavors to delineate the key research directions and topics, document the current research trends, and furnish insightful analyses and novel perspectives to foster future advancements in the field, with the aid of CiteSpace and VOS viewer.Methods: CiteSpace and VOS viewer are two kinds of software for visualizing citations that is intended to examine academic literature and identify possible sources of knowledge. The Web of Science Core Collection database was used to retrieve articles from 1994 to 2024 that discussed the autism phenotype in general. Following data collection, analyses were conducted using CiteSpace V.6.2.R4 (64-bit) on a number of topics, such as annual publication output, highly cited journals, affiliations with countries and institutions, eminent authors, cited references, and keywords. Knowledge maps, collaborative network analysis, cluster analysis, and strongest citation burst analysis were among the tools used to visualize the data.Results: A total of 1,075 articles about the broader autism phenotype were found. Roughly speaking, the annual number of publications is rising. With 546 articles on the subject, the United States is the nation with the greatest amount of authority and influence (centrality of 0.32), with England (218 articles) and Canada (115 articles) coming in second and third, respectively. The cited journals and institutions are mainly from the United States. The research consistently emphasizes the academic achievement and engagement of broader autism phenotype when analyzing the most cited references and authors.Conclusion: This study used CiteSpace to analyze the state of the larger autism phenotype field and then identified research frontiers and hotspots. As new findings are made, global trends in more thorough studies of the autism phenotype suggest that interest in these studies will only grow.
