The Power of Systemizing in Autism

A latent profile analysis of empathizing-systemizing cognitive style among Chinese children aged 6 - 12 years: Links to intelligence, executive function, and autistic traits

Background

Empathizing and systemizing abilities are respectively associated with key developmental outcomes like intelligence, executive function, and autistic traits, particularly in typically developing (TD) children. However, how specific cognitive styles-defined by the balance between empathizing and systemizing-relate to these outcomes remains unclear.

Methods

We conducted a latent profile analysis on 502 TD children aged 6‒12 years to identify cognitive styles based on multiple dimensions of empathizing and systemizing, measured by the Children's Empathy Quotient and Systemizing Quotient. Intelligence, executive function, and autistic traits were assessed using the Wechsler Intelligence Scale for Children (Fourth Edition), the Behavior Rating Inventory of Executive Function, and the Social Responsiveness Scale, respectively.

Results

Four cognitive styles emerged: High B (high empathizing and systemizing), E-dominance (empathizing-dominant), S-dominance (systemizing-dominant), and Low B (low empathizing and systemizing). The High B and E-dominance groups showed higher full-scale intelligence and verbal comprehension scores compared to the Low B group. In executive function, the Low B and S-dominance groups displayed more impairments, particularly in inhibitory control, emotional regulation, and overall executive function. For autistic traits, the S-dominance group showed higher levels of both social-communication difficulties and autistic mannerisms, while the Low B group primarily displayed increased social-communication challenges.

Conclusion

Cognitive styles marked by high empathizing and systemizing ability correlate with stronger intelligence and social-communication skills, while a systemizing-dominant profile may lead to executive function difficulties and elevated autistic traits. These findings emphasize the role of cognitive styles in developmental outcomes, with implications for tailored educational and clinical interventions.

A rule-based theoretical account of social stories to address the double empathy problem

Social Stories™ (SS) is one of the most popular and researched interventions for autistic children. To date, research that focuses on outcomes has been prioritized over the investigation of the psychological mechanisms that inform the intervention. In this article we consider theoretical accounts proposed thus far which could underpin SS. We argue that mechanisms that are based on social deficit theories lack validity, and propose a rule-based theoretical account to inform a strengths-based approach toward conceptualizing the mechanisms that underpin SS. We apply this account to the 'double-empathy problem' to propose that SS can be adapted to involve all parties in the development and delivery of SS support by adopting a rule-based perspective. We use the example of systemizing (the drive to analyze and explore systems in terms of 'if-and-then' rules), which is proposed to be a relative autistic strength, as a form of rule-based thinking that can provide a theoretical account of SS and a framework to address the double-empathy problem.

Autism Spectrum Disorder and Savant Syndrome: A Systematic Literature Review

Objectives

This study aimed to analyze research trends in autism spectrum disorder (ASD) and savant syndrome and their cognitive characteristics through a systematic literature review. The objectives of this study were to establish an overview of research trends in ASD and savant syndrome, analyze the overall characteristics of individuals with ASD and savant syndrome, and examine their cognitive characteristics.

Methods

For the systematic literature review, three criteria were used to select review articles: 1) literature from peer-reviewed journals, published in the past 15 years, from 2008 to 2022; 2) subjects with ASD and savant syndrome; 3) study objectives focused on the basic phenomenon and cognitive characteristics of ASD and savant syndrome. Finally, based on the selection criteria, a total of 40 articles were included.

Results

Five themes and nine subthemes were derived from the analysis of 40 studies. The five main themes were as follows: 1) What is savant syndrome? 2) Demographic characteristics of savant syndrome; 3) Spectra of savant syndrome; 4) Savant syndrome and ASD; and 5) Cognitive characteristics of ASD with savant syndrome. The subthemes of the cognitive characteristics were weak central coherence, detail-focused cognitive processing, enhanced perceptual functioning, and hyper-systemizing.

Conclusion

Several studies have been conducted to understand ASD and savant syndrome; however, no single theory can specify the cognitive characteristics of people with ASD and savant syndrome. Therefore, further systematic and multi-layered research on ASD and savant syndrome are required for more comprehensive results.

Increased Serum Concentrations of High Mobility Group Box 1 (HMGB1) Protein in Children with Autism Spectrum Disorder

High mobility group box 1 protein (HMGB1) has been suggested to be involved in the immune dysfunction and inflammation reported in autism spectrum disorder (ASD). We aimed to assess HMGB1 serum concentrations (SCs) in high-functioning ASD children compared to typically developing (TD) controls and to explore their associations with the autism spectrum quotient (AQ), the empathy quotient (EQ), and the systemizing quotient (SQ). The study involved 42 ASD children and 38 TD children, all-male, aged between 6.1 and 13.3 years old. HMGB1 SCs were measured by enzyme-linked immunosorbent assay (ELISA). Groups were comparable regarding age, general IQ, birth weight, and maternal age at birth. ASD children showed significantly higher HMGB1 SCs compared to TD children (1.25 ± 0.84 ng/mL versus 1.13 ± 0.79 ng/mL, respectively, p = 0.039). The Spearman’s rho revealed that HMGB1 SCs were positively correlated with the AQ attention to detail subscale (rs = 0.46, p = 0.045) and with the SQ total score (rs = 0.42, p = 0.04) in the ASD group. These results show that HMGB1 serum concentrations are altered in ASD children, and suggest that inflammatory processes mediated by HMGB1 may be associated with specific cognitive features observed in ASD.

Associations among parent and teacher ratings of systemizing, vocabulary and executive function in children with autism spectrum disorder

Individuals with Autism Spectrum Disorder (ASD) show a heightened drive toward systemizing, which is the capability to analyze, or the drive to construct, a rule-based system. In addition, executive function deficits as well as diminished language capacity and vocabulary have been consistently demonstrated in individuals with ASD. The primary purpose of this study was to create a model to understand how these constructs interact in children with ASD. Forty-six children diagnosed with ASD along with their parents and teachers participated. All children completed standardized vocabulary testing. For each child, one parent and one teacher completed executive function and systemizing scales. For parents and teachers, systemizing was significantly associated with vocabulary. For parents, systematizing was significantly associated with all executive function subscales, however, for teachers, systemizing was only significantly associated with half of the executive function subscales. The mediation model indicated that the relationship between vocabulary and systemizing was fully mediated by executive function for parents but the model was not significant for teachers. This model demonstrates that systemizing, vocabulary and executive function should not be studied in isolation when attempting to understand the behaviors of children with ASD and can help us to better plan educational and therapeutic interventions.
