Studies have proposed that individuals with autism spectrum disorder (ASD) can be divided into several subtypes depending on their sensory features. However, consideration of social communication features is also crucial for configuring ASD subtypes, because social and sensory features are tightly interrelated. In this study, we asked Japanese…

Executive function (EF) and social function are both critical skills that continue to develop through adolescence and are strongly predictive of many important life outcomes. Longstanding empirical and theoretical work has suggested that EF shapes social function. However, there is little empirical work on this topic in adolescence, despite both…

Background: The implicit learning deficit hypothesis claims that impaired implicit learning underlies deficits in social-communicative abilities associated with developmental language disorder (DLD). However, previous research testing this hypothesis revealed inconsistent results and largely used process-impure sequential learning tasks. Aims:…

This study examined the similarities/differences between the social phenotypes of Williams syndrome (WS) and autism spectrum disorder (ASD). As cultural norms may affect symptom evaluation, this study administered the Social Responsiveness Scale-2 to Japanese individuals with WS (n = 78, 4.4-44.0 years) and ASD (n = 75, 4.7-55.4 years). The scores…

Eating Disturbances (ED) are common in young people with Autism Spectrum Disorder (ASD) and may be influenced by Social Functioning and Social Anxiety, but no report has been made of the relative associations between these factors. Fifty-three girls with ASD aged (M age = 9.6 yr, range = 6 yr to 14 yr) rated their Social Anxiety and their ED, and…

Social skills are vital to everyday life; home being the first place to learn these skills. Lack of such skills is a characteristic of children with autism spectrum disorders (ASD) (Gray, 2004). This lack of social skills negatively impacts autistic children to excel in the school and community environment. They have a hard time maintaining social…

The establishment of reciprocal friendships is a challenge for many individuals with autism spectrum disorder (ASD). Social interaction difficulties emerge early, persist throughout development, and have widespread functional impact. As such, interventions focused on social functioning are needed in early intervention programs. This two-part study…

Autism spectrum disorder is characterized by difficulties with social communication, with a preponderance in males. Evidence supports a relationship between metacognitive executive functions (e.g. planning, working memory) and social communication in autism spectrum disorder, yet relationships with specific metacognitive executive functions and…

The current research evaluates the effectiveness of a behavioral skills training (BST) package used to increase appropriate conversation interactions for six adults with autism spectrum disorder (ASD). Deficits in the area of social skills can become a significant feature for individuals with disabilities and in particular for those with ASD. A…

This prospective study examined the developmental changes over time of adolescents diagnosed in toddlerhood with autism spectrum disorder and searched for child characteristics at toddlerhood that predict outcome at adolescence. The study included 65 participants who were divided into low cognitive (developmental quotient [less than] 85; N = 41)…

Peer interaction can be challenging in autism spectrum disorder, but naturalistic peer-observation scales for preschoolers are scarce. This study examined psychometric qualities of the newly developed Autism Peer Interaction Observation Scale. We tested the Autism Peer Interaction Observation Scale to (a) characterize peer interactions of…
