Eye Tracking Methodology for Studying Emotional Competence in Children with Autism Spectrum Disorder (ASD) and Specific Language Impairment (SLI): a Comparative Research Review

A systematic review and meta-analysis of atypical visual attention towards non-social stimuli in preschoolers with autism spectrum disorder

Research on attention towards non-social stimuli in preschoolers with autism spectrum disorder (ASD) has increased over the past decade; however, findings have been inconsistent. It has been suggested that stimuli relating to common circumscribed interests (CIs) elicit more attention than non-CI related stimuli. This meta-analysis synthesizes results from 31 studies that compared attention towards non-social stimuli in children with ASD under the age of five with typically developing (TD) controls using eye-tracking. Additional subgroup analysis comparing studies that employed non-social stimuli related to CIs frequently reported in adults with ASD to studies using non-CI related stimuli were conducted. Meta-regressions with age, sex, stimulus dimension, nonverbal DQ, and symptom severity were conducted. Results show small (g = 0.39) but significantly higher attention towards non-social stimuli for the ASD group. However, when studies were split based on stimulus type no significant differences for non-CI related stimuli was found. Meanwhile studies employing CI related stimuli reported significant large effects on attention allocation (g = 0.69). None of the conducted regressions reached significance. The findings show increased non-social attention in children with ASD is driven by CI related content rather than a general non-social attentional bias. The findings and future research directions are discussed.

Psychometric Features of the Arabic Version of the Children's Communication Checklist (CCC2)

Background

The Children's Communication Checklist-Second Edition (CCC-2) uniquely assesses overlooked communication elements such as pragmatics and context use, which are rarely addressed by conventional language assessments. This study focuses on the psychometric assessment of the CCC-2's Arabic version, tailored to evaluate communication challenges in Arabic-speaking children.

Aim

This study aims to validate the Arabic version of CCC-2 by testing its reliability and validity specifically for three higher-order constructs: Specific Language Impairment (SLI), Social Communication Disorder (SCD), and Impaired Behaviour within the Arabic-speaking population.

Methods

A total of 121 participants in Saudi Arabia, showcasing diverse age and gender distributions, participated in the validation process. The study employed a Reflective-Reflective Higher-Order Construct (R-R HOC) model using partial least squares-structural equation modeling (PLS-SEM) to ensure content validity and cross-cultural adaptation of the translated items. Metrics such as Cronbach's alpha for reliability and Average Variance Extracted (AVE) for convergent validity were specifically examined.

Results

The study confirmed the reliability and validity of the Arabic CCC-2, demonstrating robust psychometric properties, with Cronbach's alpha and AVE scores indicating satisfactory reliability and convergent validity across constructs. Structural model evaluation further supported the strong interrelations among the constructs of SLI, SCD, and Impaired Behaviour.

Conclusion

The results substantiate the Arabic CCC-2 as a reliable and valid tool for assessing communication challenges in Arabic-speaking children, particularly for diagnosing SLI, SCD, and Impaired Behaviour.

Implications

The validated Arabic CCC-2 has significant potential for application in clinical and educational settings and suggests directions for future research to explore its utility further in diverse clinical populations.

Beta Spectral Power during Passive Listening in Preschool Children with Specific Language Impairment

INTRODUCTION

Children with specific language impairment (SLI) have difficulties in different speech and language domains. Electrophysiological studies have documented that auditory processing in children with SLI is atypical and probably caused by delayed and abnormal auditory maturation. During the resting state, or different auditory tasks, children with SLI show low or high beta spectral power, which could be a clinical correlate for investigating brain rhythms.

METHODS

The aim of this study was to examine the electrophysiological cortical activity of the beta rhythm while listening to words and nonwords in children with SLI in comparison to typical development (TD) children. The participants were 50 children with SLI, aged 4 and 5 years, and 50 age matched TD children. The children were divided into two subgroups according to age: (1) children 4 years of age; (2) children 5 years of age.

RESULTS

The older group differed from the younger group in beta auditory processing, with increased values of beta spectral power in the right frontal, temporal, and parietal regions. In addition, children with SLI have higher beta spectral power than TD children in the bilateral temporal regions.

CONCLUSION

Complex beta auditory activation in TD and SLI children indicates the presence of early changes in functional brain connectivity.
