Declining Gaze to Faces in Infants Developing Autism Spectrum Disorder: Evidence From Two Independent Cohorts

Two independent cohorts (N = 155, N = 126) of infants at high and low risk for autism spectrum disorder (ASD) were followed prospectively between 6 and 36 months of age, when n = 46 were diagnosed with ASD. Gaze to adult faces was coded—during a developmental assessment (Cohort 1) or a play interaction (Cohort 2). Across both cohorts, most children developing ASD showed sharp declines in gaze to faces over time, relative to children without ASD. These findings suggest that declining developmental trajectories may be more common than previously recognized by retrospective methods. Trajectory-based screening methods could potentially identify children in the early stages of symptom onset and allow for early intervention before the full disorder has developed.

Faces Do Not Capture Special Attention in Children With Autism Spectrum Disorder: A Change Blindness Study

Two experiments investigated attention of children with autism spectrum disorder (ASD) to faces and objects. In both experiments, children (7- to 15-year-olds) detected the difference between 2 visual scenes. Results in Experiment 1 revealed that typically developing children ( n  = 16) detected the change in faces faster than in objects, whereas children with ASD ( n  = 16) were equally fast in detecting changes in faces and objects. These results were replicated in Experiment 2 ( n  = 16 in children with ASD and 22 in typically developing children), which does not require face recognition skill. Results suggest that children with ASD lack an attentional bias toward others' faces, which could contribute to their atypical social orienting.     

Third-Party Sociomoral Evaluations in Children With Autism Spectrum Disorder

We examined explicit and implicit processes in response to third-party moral transgressions in children with autism spectrum disorder (ASD). Twenty 4- to 7-year-old children with ASD and 19 typically developing controls evaluated dynamic visual stimuli depicting intentional or accidental harm to persons or damage to objects. Moral evaluations, eye fixations, and pupil dilations toward the stimuli were collected. Results indicate a preserved capacity to understand the mental states of perpetrators and an implicit moral sensitivity to the third-party harms in children with ASD. Nonetheless, children with ASD showed specific sensitivity and emotional arousal when viewing damage to objects. These findings contribute to the understanding of the underlying mechanisms of moral reasoning in ASD and its possible association with the autistic symptoms.     

Effects of ABRACADABRA Instruction on Spelling in Children With Autism Spectrum Disorder

This study explored the effects of an evidence-based literacy program, ABRACADABRA, on the spelling abilities of children with autism spectrum disorder (ASD). Twenty children with ASD aged 5–11 years were assigned to matched instruction and waitlist control groups. Children in the instruction group received 26 hrs of individualized, home-based instruction using ABRACADABRA over a 13-week period. Results showed no change in children’s conventional spelling accuracy skills following ABRACADABRA instruction. However, an analysis of spelling attempts using the Computerized Spelling Sensitivity System (Masterson & Hrbec, 2011) revealed statistically significant gains in linguistic spelling accuracy for children in the instruction group relative to the waitlist control group, with large effect sizes. These findings suggest that ABRACADABRA improves aspects of spelling ability in children with ASD and that the Computerized Spelling Sensitivity System is a useful tool for detecting changes in the spelling abilities of children with ASD following literacy instruction.     

Understanding Variability in Reading Comprehension in Adolescents With Autism Spectrum Disorders: Interactions With Language Status and Decoding Skill

Although it is well recognized that reading skills vary in people with autism spectrum disorders (ASD), reasons for this variability are not well understood. We used the simple view of reading model to investigate both word decoding and text comprehension processes in two well-established subtypes within the autism spectrum, those with age-appropriate structural language skills and those structural language impairments. Generally, participants with language impairments performed less well than those with age-appropriate language skills. Word-level reading was a relative strength for both groups, although it showed declines with age. Comprehension weaknesses were especially marked among those with poor structural language skills. Reading outcomes in ASD are related to variations both in decoding and comprehension and in the oral language skills that support the development of these processes.     

Early Numerical Competencies in 5- and 6-Year-Old Children With Autism Spectrum Disorder

Research Findings: To date, studies comparing the mathematical abilities of children with autism spectrum disorder (ASD) and typically developing children are scarce, and results remain inconclusive. In general, studies on this topic focus on mathematical abilities learned from elementary school onward, with little attention for possible precursors at younger ages. The current exploratory study focused on the important developmental period of preschool age, investigating 5 early numerical competencies in 30 high-functioning children with ASD and 30 age-matched control children: verbal subitizing, counting, magnitude comparison, estimation, and arithmetic operations. Children were examined at 5 or 6 years of age, attending the 3rd and final year of preschool. Overall, rather similar early number processing was found in children with and without ASD, although marginally significant results indicated a weaker performance of children with ASD on verbal subitizing and conceptual counting. Practice or Policy: Given the pervasiveness and impact of ASD on other domains of functioning, it is important to know that no general deficits in early numerical competencies were found in this study. However, some downward trends in mathematics performance were identified in children with ASD, which can serve as the basis for additional research in this field.

The Relation Between Walking and Language in Infant Siblings of Children With Autism Spectrum Disorder

In typical development, walk onset is accompanied by increased language growth (e.g., Walle & Campos, 2014). The present study explored whether this relation may be disrupted in the infant siblings of children with autism spectrum disorder (ASD; heightened risk of receiving an ASD diagnosis; HR), a population exhibiting substantial variability in motor and language development (e.g., Gamliel, Yirmiya, & Sigman, 2007; Landa & Garrett-Mayer, 2006). Receptive and expressive language were examined across the transition to walking in three groups of HR infants (no diagnosis, language delay, and ASD; N = 91, 8–18 months) and in infants with no family history of ASD (N = 25; 9–15 months). Only infants with an eventual ASD diagnosis did not show increased language growth following walk onset.     

Developing a Scale of Adaptive Behavior for Young Chinese Children With Autism Spectrum Disorder

The purpose of the present study was to develop and evaluate a scale to measure adaptive behavior skills in Chinese children with autism spectrum disorder (ASD). Participants were 121 young children (M = 55.18 months, SD = 0.18 months) with a formal diagnosis of ASD (73% male). Psychometric evaluation indicated that the reliability and validity of this scale were good. Furthermore, independent t‐tests revealed that boys demonstrated better adaptive behavior skills than girls. The present findings suggest that the scale is a valid measure of adaptive behavior skills in Chinese children with ASD.

Sibling Adjustment and Maternal Well-Being: An Examination of Families With and Without a Child With an Autism Spectrum Disorder

Differences in sibling social, behavioral, and academic adjustment and maternal well-being in families with (n = 20) and without (n = 23) a preschooler with autism spectrum disorder (ASD) were explored. Results are interpreted to suggest that mothers of children with autism report more daily hassles, life stress, and depression than mothers without a child with ASD. There were no significant differences in parent and teacher reports of older siblings' social, behavioral, and academic adjustment in families with and without a child with ASD. Sibling behavioral adjustment was, however, significantly related to maternal well-being. Because families with children with ASD often experience more parenting stress and depression, siblings may be more vulnerable to the cumulative risks over time.     

The Developmental Sequence and Relations Between Gesture and Spoken Language in Toddlers With Autism Spectrum Disorder

In typical development, gestures precede and predict language development. This study examines the developmental sequence of expressive communication and relations between specific gestural and language milestones in toddlers with autism spectrum disorder (ASD), who demonstrate marked difficulty with gesture production and language. Communication skills across five stages (gestures, word approximations, first words, gesture-word combinations, and two-word combinations) were assessed monthly by blind raters for toddlers with ASD participating in an randomized control trial of parent-mediated treatment (N = 42, 12–30 months). Findings revealed that toddlers acquired skills following a reliable (vs. idiosyncratic) sequence and the majority of toddlers combined gestures with words before combining words in speech, but in contrast to the pattern observed in typical development, a significant subset acquired pointing after first words.     

Imitation and Pantomime in High-Functioning Adolescents with Autism Spectrum Disorders

A study was designed to test 2 alternative hypotheses—a symbolic hypothesis and an executive function hypothesis—for the imitation and pantomime deficits found in previous studies of autism. The subjects were 17 adolescent high-functioning subjects with autism spectrum disorders and 15 clinical comparison subjects who were matched on chronological age and verbal IQ. Meaning and sequence were manipulated in facial and manual imitation tasks. Sequence was manipulated in the pantomime and control tasks. Recognition memory and motor control tasks were matched to the experimental tasks. The results provided no support for the symbolic deficit hypothesis; meaning aided rather than hindered the performance of the group with autism. Partial support for the executive deficit hypothesis was found. There were no group differences on motor control tasks, and few on the memory control tasks, arguing against deficits in motor initiation, basic motor coordination, or visual recognition memory.     

A design model: the Autism Spectrum Disorder Classroom Design Kit

Architects and designers have a responsibility to provide an inclusive built environment. However, for those with a diagnosis of autism spectrum disorder (ASD), the built environment can be a frightening and confusing place, difficult to negotiate and tolerate. The challenge of integrating more fully into society is denied by an alienating built environment. For ASD pupils in a poorly designed school, their environment can distance them from learning. Instead, if more at ease in their surroundings, in an ASD‐friendly environment, the ASD pupil stands a greater chance of doing better. However, a difficulty exists in that most architects are not knowledgeable in designing for those with ASD. Any available design guidelines for architects tend, because of the inherent difficulties associated with a spectrum, to be general in their information. Therefore, in order to provide an ASD‐friendly learning environment, there is a need to ensure that teachers, as the experts, can most clearly and effectively impart their knowledge and requirements to architects. This article, written by Keith McAllister and Barry Maguire, both from Queen's University Belfast, sets out the challenges and difficulties inherent in the design process when designing for those with ASD. It then sets out an alternative strategy to the usual method of drawing‐centric dialogue between teacher and architect by using models instead as a basis for a more common language. An ASD Classroom Design Kit was designed and developed by architecture students at Queen's University Belfast. It was then used by ASD teaching staff from the Southern Education and Library Board in Northern Ireland as a case study to trial its effectiveness. This article outlines how the study was carried out before concluding with reflections by both teaching staff and architect on using the ASD Classroom Design Kit. It is hoped, firstly, that this article will highlight the need for better dialogue between expert and architect when considering ASD and the built environment and, secondly, that it may encourage others to consider using models to convey their ideas and knowledge when designing, not just for ASD, but for other special educational needs and disabilities.     

Infant Motor Development in Autism Spectrum Disorder: A Synthesis and Meta-analysis

Studies of infant motor development in autism spectrum disorder (ASD) have increased in recent years. This article synthesized this literature through meta-analysis to assess (a) whether infant motor ability differs in ASD relative to neurotypical controls; and (b) whether motor ability and communication are related in infants with ASD. Study 1 aggregated data from 1,953 infants with ASD (ages 3.0–42.0 months), and Study 2 included 890 infants with ASD (age 6.0–42.9 months). Study 1 revealed that infant motor ability differed significantly in ASD compared with neurotypical infants—this difference was robust to variation in measurement and design. Furthermore, this group difference amplified as age increased. Study 2 indicated that within ASD, infant motor ability and communication are related.     

Outcomes of Home-Support Consultation on the Maintenance of Bicycle-Riding Skills for Youth With Autism Spectrum Disorder

Bicycle riding is a functional motor skill that increases physical activity opportunities, social interaction, and independence. However, bicycle riding is difficult for youth with autism spectrum disorder (ASD) to learn. This study examined the effectiveness of home-support consultation (HSC) on increasing the maintenance of independent bicycle riding following initial skill acquisition. Fifty-one youth with a confirmed ASD diagnosis learned to ride a two-wheeled bicycle during a training camp. Twenty-nine riders enrolled in a HSC intervention to promote distributed practice of the learned skill. The control cohort (N = 22) was exempt from the HSC intervention. One year following initial skill acquisition, 62.07% of the HSC cohort compared to 36.36% of the control cohort still reportedly displayed the skill. Within the HSC cohort, riders who reported at least 8 weeks of practice following acquisition on average maintained the skill. Implications of home consultation are discussed.     

Looking at Eye Gaze Processing and Its Neural Correlates in Infancy—Implications for Social Development and Autism Spectrum Disorder

The importance of eye gaze as a means of communication is indisputable. However, there is debate about whether there is a dedicated neural module, which functions as an eye gaze detector and when infants are able to use eye gaze cues in a referential way. The application of neuroscience methodologies to developmental psychology has provided new insights into early social cognitive development. This review integrates findings on the development of eye gaze processing with research on the neural mechanisms underlying infant and adult social cognition. This research shows how a cognitive neuroscience approach can improve our understanding of social development and autism spectrum disorder.
