The current study examined the associations between internalizing symptoms, social motivation, and gender among autistic and non-autistic youth. Caregivers of 386 participants age 6 to 14 years completed measures of their child’s internalizing symptoms and social motivation. Correlation and hierarchical regression analyses were conducted to compare...

Background/Objectives: Children with Autism Spectrum Disorder (ASD) face challenges in social communication due to difficulties in considering context, processing information, and interpreting social cues. This study aims to explore the neural processes related to pragmatic language communication in children with ASD and address the research questi...

Dante Cicchetti’s earliest work, his studies of social-emotional development in infants and children with Down syndrome, set the stage for the emergence of the larger field of developmental psychopathology. By applying basic developmental principles, methodologies, and questions to the study of persons with Down syndrome, Dante took on the challeng...

When evaluated in a social context, autistic people are consistently evaluated more negatively than non-autistic people. This negative bias has the potential to be particularly harmful if held by influential role models, such as teachers. Teachers play a pivotal role in shaping children's learning, mental health, and academic success. As such, this...

Background: Though autism is most often diagnosed during childhood, the number of adults pursuing autism assessments during adulthood has increased (Huang et al., 2020). Adults are often motivated to complete autism diagnostic assessments to help make sense of their life experiences (Hickey et al., 2018) and to seek support for the challenges that...

Purpose: Autistic individuals often face challenges perceiving and expressing emotions, potentially stemming from differences in speech prosody. Here we explore how autism diagnoses between groups, and measures of social competence within groups may be related to, first, children’s speech characteristics (both prosodic features and amount of sponta...

Autistic individuals have difficulty perceiving and expressing emotions. Since prosodic changes in speech (i.e. changes in intonation, stress, and rhythm, etc.) are crucial for extracting information about the emotional state of the speaker, differences in perceiving and interpreting these prosodic changes may lead to challenges in social communica...

Background Decreased sound tolerance (DST) is an increased sensitivity to sound at levels that would not bother most people. DST is highly prevalent in autistic adults; however, the extent to which DST differs across autistic and non-autistic adults is uncertain. This study explores multiple domains of DST symptoms and the severity of DST symptoms,...

Autism Spectrum Disorder (ASD) is characterized by both atypical functional brain connectivity and cognitive challenges across multiple cognitive domains. The relationship between task-dependent brain connectivity and cognitive abilities, however, remains poorly understood. In this study, children with ASD and their typically developing (TD) peers...

Introduction Although autism inclusion and acceptance has increased in recent years, autistic people continue to face stigmatization, exclusion, and victimization. Based on brief 10-second videos, non-autistic adults rate autistic adults less favourably than they rate non-autistic adults in terms of traits and behavioural intentions. In the current...

Difficulties in various face processing tasks have been well documented in autism spectrum disorder (ASD). Several meta‐analyses and numerous case–control studies have indicated that this population experiences a moderate degree of impairment, with a small percentage of studies failing to detect any impairment. One possible account of this mixed pa...

In the last 50 years, the study of brain development has brought major discoveries to education and medicine, changing the lives of millions of children and families. However, collecting behavioral and neurophysiological data from children has specific challenges, such as high rates of data loss and participant dropout. We have developed a science...

Negative judgements of autistic people relative to non-autistic people have been consistently reported. In order to develop methods for improving people’s perceptions of autistic people, it is important to understand what factors may influence these judgements. In this study, autistic adults, parents of autistic people, professionals who work with...

The current study examined whether social competence and autistic traits are related to anxiety and depression in autistic and non-autistic children. Parents of 340 children aged 6 to 12 years old, including 186 autistic and 154 non-autistic children completed the Autism Spectrum Quotient (AQ) to assess their child’s autistic traits, the Multidimen...

The goal of this study was to better understand the relations between parent perceptions of social connectedness and well-being.

This study aimed to investigate the phonological awareness (PA) skills of school age autistic children (age range = 6–12) in two parts: (1) comparing their performance on a PA task to non-autistic children with groups matched on chronological age, verbal and non-verbal cognitive skills, and (2) exploring the role of cognitive skills and autism char...

Lay abstract: The experiences of coping in parents of autistic children have been extensively studied in the literature. While this research has identified both effective and ineffective coping strategies used by caregivers, no studies to date have examined how coping strategies used by parents might be linked to family quality of life outcomes. F...

Decreased sound tolerance (DST) is the most common sensory difficulty experienced by autistic individuals. Parents of 88 autistic children and young adults between the ages of 3 and 30 described coping strategies and physical and emotional responses used to deal with distressing sounds, and their impact on daily activities. Loud, sudden, and high-p...

Introduction: Autistic children have difficulties forming positive social relationships. Stigmatization of autism may influence the negative social experiences of autistic children (Han et al., 2021). First impressions formed from viewing 10-second video clips of autistic adults were less favourable than those of non-autistic adults (DeBrabander et...

Children with autism spectrum disorder (ASD) experience difficulties with social communication, making it challenging to interpret contextual information that aids in accurately interpreting language. To investigate how the brain processes the contextual information and how this is different in ASD, we compared event-related potentials (ERPs) in re...

Alexithymia impacts an individual’s ability to recognize and understand emotions and frequently co-occurs with autism. This study investigated the relationship between children’s alexithymia, autistic traits, and caregiver reactions to their child’s negative emotions. Caregivers of 54 autistic and 51 non-autistic children between the ages of 7 and...

Background: Social communication difficulties are a clinical characteristic of autism, but social interactions are reciprocal in nature and autistic individuals' social abilities may not be the only factor influencing their social success. Nonautistic individuals' social perceptions and behavior also contribute to autistic individuals' social diff...

Background Social communication difficulties are a clinical characteristic of autism, but social interactions are reciprocal in nature and autistic individuals’ social abilities may not be the only factor influencing their social success. Non-autistic individuals’ social perceptions and behavior also contribute to autistic individuals’ social diffi...

Background: Camouflaging, defined as the use of strategies to compensate for or hide autistic traits, is associated with internalizing behaviour (i.e., anxiety and depression) in both autistic and non-autistic people. Non-autistic adults who have poorer social competence tend to engage in more camouflaging, thus it’s unclear whether the increase in...

Social functioning difficulties are a core diagnostic feature of autism spectrum condition (ASC) and are commonly assessed in ASC research. Many measures have been created to assess the various dimensions of social functioning; thus, it is important to evaluate how each scale captures these latent constructs in order to integrate results from studi...

Alexithymia impacts an individual’s ability to recognize and understand emotions and frequently co-occurs with autism. This study investigated the relationship between children’s alexithymia, autistic traits, and caregiver reactions to their child’s negative emotions. Caregivers of 54 autistic and 51 non-autistic children between the ages of 7 and...

When two participants perform a go/no go task, sharing the same display but responding to different targets, their responses show a spatial compatibility effect. A shape on the side of a participant is responded to faster than that on the neighbour’s side. This is called the Joint Simon effect (JSE), and it vanishes when participants perform the sa...

Lay abstract: Perceptions and experiences of culturally and linguistically diverse groups in accessing autism services in Canada are extremely limited. Thus, this study partnered with a community member to explore Korean immigrant parents' perceptions of barriers and facilitators to accessing autism services in British Columbia, Canada. Interviews...

This study examined involuntary capture of attention, overt attention, and stimulus valence and arousal ratings, all factors that can contribute to potential attentional biases to face and train objects in children with and without autism spectrum disorder (ASD). In the visual domain, faces are particularly captivating, and are thought to have a ‘s...

Developmental approaches provide inclusive, universal, and methodologically rigorous frameworks for studying persons with intellectual disability (ID). This is an exceptionally heterogenous group with regard to etiology, genotype, and phenotype that simply shares the traditional diagnostic criteria, typically a score of two standard deviations belo...

We present this article as a testament to Ed Zigler's commitment to science in the service of humanity and to policy based on conceptually compelling theory and methodologically rigorous science. In doing so, we highlight ways that Ed's universal and inclusive developmental world view, early training as a behaviorist, exacting scientific standards,...

The present research investigated how alexithymia and autism influence caregivers’ reactions to their child’s negative emotional expressions. It was hypothesized that autistic children would exhibit higher alexithymia and autistic traits, and that caregivers of autistic children would report greater supportive, and less restrictive/controlling, par...

Individuals with autism spectrum disorder (ASD) can experience difficulties functioning in society due to social communication deficits and restrictive and repetitive behaviors. Music therapy has been suggested as a potential intervention used to improve these deficits in ASD. The current systematic literature review focuses on two methods of music...

Alexithymia is characterized by difficulties identifying and describing one's own emotions and the emotions of others. These challenges with understanding emotions in people with alexithymia may give rise to difficulties with social interactions. Given that alexithymia frequently co‐occurs with autism spectrum disorder (ASD), and that both populati...

Lay abstract: Using self-report questionnaires is an important method in the assessment and treatment of children with autism. Self-reports can provide unique information about children's feelings and thoughts that is not available through other methods such as parent-reports. However, many clinicians are not sure whether children with autism can...

This study sought to examine and compare conceptualizations and descriptions of family quality of life, from the perspectives of Korean immigrant and Canadian families of children with autism spectrum disorder. Thematic analysis of semi-structured interviews from 13 Korean immigrant parents and 12 Canadian parents of children with autism living in...

The current study examined the role of informal supports in predicting resilience among families of children with autism spectrum disorder. Participants included 153 caregivers of children with autism spectrum disorder, who were between the ages of 2 and 18 years ( M = 10.45; SD = 4.32). Caregivers completed a measure of satisfaction with informal...

Objective A systematic review of mental health outcomes and needs of children and families during past pandemics was conducted based on the PRISMA protocol. The objectives were to evaluate the quality of existing studies on this topic, determine what is known about mental health outcomes and needs of children and families, and provide recommendatio...

Autism spectrum disorder (ASD) is a developmental disorder characterized by persistent deficits in social communication and interaction. Speech is an important form of social communication. Prosody (e.g. vocal pitch, rhythm, etc.), one aspect of the speech signal, is crucial for ensuring information about the emotionality, excitability, and intent...

All children with autism spectrum disorder (ASD) experience social difficulties but they differ with regard to the type and severity of their challenges. Potentially powerful interventions targeting social skills in children with ASD may have limited effectiveness if they are not tailored to the child's specific needs. One factor that may influence...

PurposeDue to the nature and complexity of autism spectrum disorder (ASD), which typically requires coordination among various treatments targeting different areas of need, the entire family is impacted. Family quality of life (FQOL) research has emerged to address the range of adaptation families experience when raising a child with ASD. One facto...

Despite average or above cognitive and verbal abilities, many children with autism spectrum disorder (ASD) experience difficulties in functional and social communication. Executive functioning (EF) may be the cognitive and regulatory mechanism that underlies these difficulties. Parents rated 92 children with ASD as demonstrating significantly more...

Unlabelled: The number of autistic students in colleges is growing rapidly. However, their needs are not being met, and graduation rates among this population remain low. This article describes the implementation and evaluation of the Autism Mentorship Initiative (AMI) for autistic undergraduates (mentees), who received 1-on-1 support from upper-l...

Autism spectrum disorder (ASD) is diagnosed more often in males with a ratio of 1:4 females/males. This bias is even stronger in neuroimaging studies. There is a growing evidence suggesting that local connectivity and its developmental trajectory is altered in ASD. Here, we aim to investigate how local connectivity and its age-related trajectories...

A systematic review of autism spectrum disorder and substance use and abuse was conducted based on the Preferred Reporting Items for Systematic Review and Meta-Analysis protocol guidelines (an internationally recognized standardized methodological framework for conducting systematic review). The objectives of the review were to update and extend fi...

Background: Autistic individuals often experience difficulties in social settings. Although autistic individuals may not intuitively know the "typical" way to behave in social settings, many autistic individuals have a desire to fit in so they develop techniques to "camouflage" their autistic traits. Although camouflaging may help individuals to n...

Individuals diagnosed with autism spectrum disorder (ASD) have difficulty perceiving and expressing emotions. Since prosodic changes in speech (i.e. changes in intonation, stress, rhythm, etc.) are crucial for extracting information about the emotional state of a speaker, an inability to perceive and interpret these prosodic changes may be related...

“Joint action”—the ability to coordinate actions with others—is critical for achieving individual and interpersonal goals and for our collective success as a species. Joint actions require accurate and rapid inferences about others’ goals, intentions, and focus of attention, skills that are thought to be impaired in individuals with autism spectrum...

Edward Zigler transformed the science and humanity of the work with persons with intellectual disability. The developmental approach is Ed's great contribution to the field of intellectual disability as it both led to more conceptually compelling and methodologically rigorous science and provided an alternative to the Zeitgeist of segregation, defe...

Autism spectrum disorder (ASD) is an increasingly common neurodevelopmental disorder that affects 1 in 59 children. The cognitive profiles of individuals with ASD are varied, and the neurophysiological underpinnings of these developmental difficulties are unclear. While many studies have focused on overall group differences in the amplitude or late...

Parent mediated interventions have the potential to positively influence the interactions and developmental outcomes of children with autism spectrum disorder (ASD). However, a range of factors relating to children, parents and caregivers, and study design may impact on outcomes and thus the generalizability of these interventions to the broader co...

Autism Spectrum Disorder (ASD) is an increasingly common developmental disorder that affects 1 in 59 children. Despite this high prevalence of ASD, knowledge regarding the biological basis of its associated cognitive difficulties remains scant. In this study, we aimed to identify altered neurophysiological responses underlying inhibitory control an...

Background The family system represents a critical context within which children develop. Although raising a child with a disability may represent a challenge to this dynamic system, research demonstrates that families have the capacity to demonstrate both maladaptation and resilience in the face of related stressors. In the current study, we exami...

The current study contributes to previous work on measuring the social phenotype in Autism Spectrum Disorder (ASD) by validating a multidimensional test of social competence developed for use with individuals with and without ASD. The “Multidimensional Social Competence Scale” (MSCS) was previously validated as a parent-rating scale with youth 11–1...

It has been proposed that autism spectrum disorder (ASD) may be characterized by an extreme male brain (EMB) pattern of brain development. Here, we performed the first investigation of how age‐related changes in functional brain connectivity may be expressed differently in females and males with ASD. We analyzed resting‐state functional magnetic re...

Individuals with autism spectrum disorder (ASD) often have difficulties with processing identity and expression in faces. This is at odds with influential models of face processing that propose separate neural pathways for the identity and expression domains. The social-motivation hypothesis of ASD posits a lack of visual experience with faces as t...

Generalized anxiety and depression symptoms may be associated with poorer social outcomes among children with Autism Spectrum Disorder (ASD) without intellectual disability. The goal of this study was to examine whether generalized anxiety and depression symptoms were associated with social competence after accounting for IQ, age, and gender in typ...

Lay summary: We examined whether parents' ratings of their children's flexibility and ability to monitor their behavior predicted adaptive skills (e.g., ability to complete day-to-day personal tasks, communicate, and socialize) and symptoms of anxiety and depression among children with and without autism spectrum disorder. For both groups, childre...

Adolescents with intellectual disability are at significant risk for developing concomitant mental health and behavior problems. Youth who experience “dual diagnosis” face great challenges, and require interventions that will promote their autonomy, self-determination, and adaptive functioning. In this article, we devote attention to innovative com...

Using a novel naturalistic paradigm allowing participants the freedom to spontaneously select and follow gaze cues in their environment, this study extends previous research conducted with younger children to determine whether school-age children with autism spectrum disorder (ASD, n = 17) demonstrate abnormal gaze following relative to typically d...

Parents and professionals are concerned that second language exposure may delay communication in children with ASD. In this study 174 youth (6–16 years) with and without ASD, exposed to a second language, were compared on executive function (EF) and functional communication (FC) with their peers without exposure. There were no significant differenc...

This research looked at Biba: a suite of mobile games intended to get kids back out to playgrounds and engaging in more moderate to vigorous physical activity (MVPA). Year after year, annual national surveys report a general decline in physical activity amongst children and a corresponding increase in screen time. Further to this, time spent outsid...
