Cognitive style refers to how individuals perceive their environment and solve problems. Among various cognitive styles documented, verbal and visual styles, including object versus spatial cognition, have been widely studied. "Thinking in pictures" is often associated with autism and characterized by enhanced performance and autonomy of certain perceptual areas. This study aimed to characterize the cognitive style of autistic individuals, focusing on this visual "thinking in pictures" style. We assessed 43 autistic and 42 non-autistic adults using the Object Spatial Imagery Verbal Questionnaire to evaluate three dimensions of their cognitive style: visual object, visual spatial, and verbal. Using a cluster analysis, we identified cognitive style profiles. We then examined manifestations of cognitive style within these profiles, including mental imagery abilities (with the Mental Rotation Test), the vividness of mental images (with the Vividness of Visual Imagery Questionnaire), language abilities (with the Mill Hill vocabulary test), and synesthetic experiences. Our results revealed three distinct cognitive profiles: a visual profile characterized by significant mental imagery and vivid mental images, a visuo-spatial profile associated with strong abilities to manipulate mental images but lower vividness of mental images, and a verbal profile with lower spatial imagery and manipulation abilities. While all profiles were observed in autistic individuals, the visual cognitive profile was the most common. Additionally, we found synesthesia to be more prevalent in the autistic population compared to the non-autistic population. This study confirms that, while not exclusive, a visual cognitive style is prevalent among autistic individuals.

The experiences of special education teachers in Saudi Arabia are quite different from the experiences of their counterparts from other countries as they work in a unique culture and educational system. The educational system in Saudi Arabia is gender segregated, and the Saudi Arabian Ministry of Education (MoE) provides an equal budget, salaries, and subsidies and implements the same policies and uses the same curriculum regardless of the location, size of the city, or the number of students. This country's unique characteristics may influence special education teachers' experiences, which raises the need to investigate and understand the experiences of Saudi special education teachers. We sought to understand the experiences of special education teachers in Saudi Arabia, focusing on teaching communication skills to autistic students. We conducted semi-structured interviews with 13 Saudi special education teachers to gain deeper insights into the experiences of these teachers within the Saudi context. The themes that emerged from the interviews revolved around evaluating and teaching communication skills, the role of the Saudi MoE, and the perceived challenges and needs related to teaching communication skills. Building on our findings, we propose a set of recommendations for special education teachers and the Saudi MoE.

This systematic review expands the current knowledge about Peer-Mediated Interventions (PMIs) for children with Autism Spectrum Disorder, focusing exclusively on primary school age (6-12 years). The study has three aims: (1) describing the main features of the PMI programs; (2) discussing the PMIs efficacy on autistic children's social skills; (3) analyzing whether the PMIs were coherent with the bio-psycho-social model promoted by the International Classification of Functioning, Disability and Health (ICF) classification system, by referring to the person-environment interaction and to the concepts of body functions and structures, environmental factors, and activity and participation. The systematic review followed the PRISMA-P method. The literature search was conducted in August 2024 through PsycInfo, PsycArticles, Education Source, and PubMed databases. A total of 558 articles were generated; 1 study was later added. Twenty-four articles were finally included. Most of the studies used a multiple baseline design across subjects and proved to be effective. Yet, only 5 studies included a follow-up assessment, which showed contrasting results. PMIs partly fit the ICF bio-psycho-social vision, even if they were not designed for this purpose. Our analysis arises from the belief that systematically including the perspective of individual-environment interaction could better guarantee the intervention efficacy.

Previous research suggests that individuals with autism spectrum disorder (ASD) may experience working memory (WM) problems, but the nature of the underlying disruption remains unknown. A recent study (Bodner et al. 2019) found that young adults with ASD experienced intact WM capacity but disruptions in their ability to efficiently filter and allocate attention. The goal of the present study was to extend this work and evaluate potential disruptions in WM capacity and attentional allocation ability in adolescents with ASD. A sample of 38 adolescents with ASD and 39 adolescents without ASD aged 11-15 years completed a computerized WM task. In brief, participants were shown visual arrays consisting of four or six colored stimuli (circles and squares). After a short delay, memory for one of the stimuli was probed. Importantly, participants were informed beforehand that one of the shapes (e.g., circles) was more likely to be probed compared to the other shape (e.g., squares) - thus making it strategically beneficial to focus primarily on the high frequency shapes. The ASD group demonstrated overall lower WM capacity compared to the non-ASD group. However, no group differences were seen in attentional allocation. There was also no evidence of sex-related differences in WM performance in adolescents with ASD. Taken together with previous findings, the current results suggest that adolescents with ASD show disruptions in WM capacity that are resolved by adulthood. Future longitudinal research is needed to further disentangle the component processes of WM and the developmental trajectories of these components.

This study adopts a person-centered approach to evaluate personality diversity as a source of interpersonal variability in autistic children and adolescents, and how personality subgroup membership relates to variability in autistic characteristics, social-emotional presentations, and parenting outcomes. Latent Profile Analysis was used to analyze 569 parent reports on a child-based Five-Factor-Model personality measure (aged 6-18 years; M_age = 11.8 years, SD = 3.1; 70% boys). Four distinct personality profile groups were identified, showing varying levels in the low to average range of all five personality domains. All groups scored lowest on Extraversion and Emotional Stability. They differed the most in Imagination and the least in Emotional Stability. Group 1 (n = 72) exhibited the lowest mean-level scores on all five domains, whereas Group 4 (n = 90) had the highest domain scores. Group 2 (n = 307) and Group 3 (n = 100) showed more diverse patterns. Group membership was meaningfully associated with variation in characteristics of social interaction and communication, internalizing, externalizing, and attentional problems, psychosocial strengths, and positive parenting strategies. Only modest group differences were found in parenting stress. All groups had similar scores on repetitive and restrictive behaviors. These findings help to better understand and support natural subgroups within the autism phenotype by exploring shared personality attributes.

With the rise in attention towards Neurodevelopmental Disorders in Hong Kong and worldwide, understanding the role of social ecological resilience in reducing parenting stress and enhancing child outcomes is crucial, particularly within the unique cultural context of Chinese families. This study utilized a social ecological model to examine resilience factors at individual and interpersonal levels among Hong Kong parents of children with Neurodevelopmental Disorders. It also compared the stress and resilience conditions and differential functions of social ecological resilience between parents with and without children diagnosed with Neurodevelopmental Disorders. A sample of 447 parents of children with and without Neurodevelopmental Disorders were assessed by a newly developed Social Ecological Resilience Scale, along with measures of parenting stress and the internalizing and externalizing behaviors of their children. Independent sample t-tests showed that Chinese parents of children with Neurodevelopmental Disorders report significantly higher parenting stress and more internalizing and externalizing difficulties in their children compared to those without Neurodevelopmental Disorders. Multiple linear regression analyses indicated that enhanced social ecological resilience among parents predicted improved parenting stress and better outcomes in children's behaviors. Notably, social ecological resilience factors showed varying effects between parents with and without children diagnosed with Neurodevelopmental Disorders. These findings highlight that both individual and interpersonal resilience factors among parents predicted improved parenting stress and better outcomes in children's behaviors and certain resilience factors may be contextually motivated. Policy makers and practitioners should consider developing context-specific strategies and programmes to help the focal target group.

There is a paucity of information on the sociodemographic and clinical characteristics of autistic children with high support needs. This study aims to address this gap by profiling a cohort of 915 children enrolled in full-time early intervention for autism spectrum disorder (ASD) in Australia between 2012 and 2024. Intake questionnaires assessed the sociodemographic characteristics of families entering the service. Clinical measures included the Autism Diagnostic Observation Schedule (2nd ed.), Mullen Scales of Early Learning, and Vineland Adaptive Behaviour Scale (2nd and 3rd eds.). Family measures included the Parenting Stress Index (4th ed., Short Form) and Autism Family Experience Questionnaire. Results indicated a male to female ratio of 3.8:1, clear delays from the age of first concern to diagnosis and intervention, and notable proportions of culturally diverse families. While clinical data indicated cognitive and adaptive deficits beyond findings in other ASD studies, measures of stress and family experiences were comparable to other autism literature. By reporting these findings, this study aims to facilitate a more informed, tailored and nuanced approach to addressing the unique challenges faced by autistic children with high support needs. The scope and limitations of this cohort are discussed.
