Developmental Predictors of Cognitive and Adaptive Outcomes in Genetic Subtypes of Autism Spectrum Disorder / Anne B. ARNETT in Autism Research, 13-10 (October 2020)
[article]
Titre : Developmental Predictors of Cognitive and Adaptive Outcomes in Genetic Subtypes of Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Anne B. ARNETT, Auteur ; Jennifer BEIGHLEY, Auteur ; Evangeline C. KURTZ-NELSON, Auteur ; Kendra HOEKZEMA, Auteur ; Tianyun WANG, Auteur ; Raphael BERNIER, Auteur ; Evan E. EICHLER, Auteur Article en page(s) : p.1659-1669 Langues : Anglais (eng) Mots-clés : developmental psychology genetic/genomic syndromes genetics intellectual disability subtypes of ASD Index. décimale : PER Périodiques Résumé : Approximately one-fourth of autism spectrum disorder (ASD) cases are associated with a disruptive genetic variant. Many of these ASD genotypes have been described previously, and are characterized by unique constellations of medical, psychiatric, developmental, and behavioral features. Development of precision medicine care for affected individuals has been challenging due to the phenotypic heterogeneity that exists even within each genetic subtype. In the present study, we identify developmental milestones that predict cognitive and adaptive outcomes for five of the most common ASD genotypes. Sixty-five youth with a known pathogenic variant involving ADNP, CHD8, DYRK1A, GRIN2B, or SCN2A genes participated in cognitive and adaptive testing. Exploratory linear regressions were used to identify developmental milestones that predicted cognitive and adaptive outcomes within each gene group. We hypothesized that the earliest and most predictive milestones would vary across gene groups, but would be consistent across outcomes within each genetic subtype. Within the ADNP group, age of walking predicted cognitive outcomes, while age of first words predicted adaptive behaviors. Age of phrases predicted adaptive functioning in the CHD8 group, but cognitive outcomes were not clearly associated with early developmental milestones. Verbal milestones were the strongest predictors of cognitive and adaptive outcomes for individuals with mutations to DYRK1A, GRIN2B, or SCN2A. These trends inform decisions about treatment planning and long-term expectations for affected individuals, and they add to the growing body of research linking molecular genetic function to brain development and phenotypic outcomes. LAY SUMMARY: Researchers have found many genetic causes of autism including mutations to ADNP, CHD8, DYRK1A, GRIN2B, and SCN2A genes. We found that each genetic cause had different early developmental milestones that explained the overall functioning of the children when they were older. Depending on the genetic cause, the age that a child first starts walking and/or talking may help to better understand and support a child's development who has a mutation to one of the above genes.

Titre : Child development as social action: Reflections on four underrated contributions of Edward Zigler to science and society Type de document : Texte imprimé et/ou numérique Auteurs : Arthur J. REYNOLDS, Auteur Année de publication : 2021 Article en page(s) : p.466-482 Langues : Anglais (eng) Mots-clés : Head Start developmental psychology early childhood development poverty social programs and policies Index. décimale : PER Périodiques Résumé : In a career spanning six decades, Edward Zigler redefined developmental psychology as the equal integration of scientific inquiry and evidence with social policy formulation and analysis to improve child well-being. The theme of his accumulated work was advancing child development as social action for children and families. Besides early childhood intervention and policy, for which he devoted most of his time, Dr. Zigler did pioneering work in education and school reform, social policy, prevention, child maltreatment, family support, developmental disabilities, and in service to government. In this article, I reflect on four of Dr. Zigler's major contributions to science and society that are underrated and, in many respects, under-appreciated in the larger context of the field. These are (a) historical analysis of Head Start, (b) conceptualization and analysis of motivation as a key component of early childhood program impacts, (c) development of preschool-to-third-grade programs and school reforms, and (d) critical analysis of theory, research, policy, and practice. Together, these and other contributions by Dr. Zigler provide a strong foundation to build a better society for all.

[article]
Titre : Auditory-visual misalignment: A theoretical perspective on vocabulary delays in children with ASD Type de document : Texte imprimé et/ou numérique Auteurs : Courtney E. VENKER, Auteur ; Allison F. BEAN, Auteur ; S. T. KOVER, Auteur Article en page(s) : p.1621-1628 Langues : Anglais (eng) Mots-clés : attention auditory developmental psychology language learning visual Index. décimale : PER Périodiques Résumé : In this commentary, we describe a novel theoretical perspective on vocabulary delays in children with autism spectrum disorder (ASD)-a perspective we refer to as auditory-visual misalignment. We synthesize empirical evidence that: (a) as a result of differences in both social and nonsocial visual attention, the auditory-visual statistics available to children with ASD for early word learning are misaligned; (b) this auditory-visual misalignment disrupts word learning and contributes to the vocabulary delays shown by children with ASD; and (c) adopting a perspective of auditory-visual misalignment has important theoretical and clinical implications for understanding and supporting vocabulary development in children with ASD. Theoretically, the auditory-visual misalignment perspective advances our understanding of how attentional differences impact vocabulary development in children with ASD in several ways. By adopting the point of view of the child, we provide a framework that brings together research on social and domain-general visual attention differences in children with ASD. In addition, the auditory-visual misalignment perspective moves current thinking beyond how misalignment disrupts vocabulary development in the moment, and considers the likely consequences of misalignment over developmental time. Finally, considering auditory-visual misalignment may assist in identifying active ingredients of existing language interventions or in developing new interventions that deliver high quality, aligned input. Future research is needed to determine how manipulating auditory-visual alignment changes word learning in ASD and whether the effects of auditory-visual misalignment are unique to ASD or shared with other neurodevelopmental disorders or sources of language impairment. Autism Research 2018, 11: 1621-1628. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This article describes a new way of thinking about vocabulary delays in children with autism spectrum disorder (ASD). We suggest that children with ASD may have difficulty learning words because their attention is not tuned in to what is most important for learning, creating a mismatch between what they see and what they hear. This perspective brings together research on different types of attentional differences in people with ASD. It may also help us to understand how language interventions work.

BOYD, Auteur Article en page(s) : p.1145-1160 Langues : Anglais (eng) Mots-clés : behavioral intervention biomarker developmental psychology early intervention infants Index. décimale : PER Périodiques Résumé : Abstract The aim of this systematic review was to determine the efficacy of very early interventions for infants and toddlers at increased likelihood of or diagnosed with autism for autism symptomatology, developmental outcomes and/or neurocognitive markers. Eight databases were searched (14 April 2022) with inclusion criteria: (i) RCTs with care as usual (CAU) comparison group, (ii) participants at increased likelihood of or diagnosed with autism and aged <24?months corrected age (CA), (iii) parent-mediated and/or clinician directed interventions, and (iv) outcome measures were autism symptomatology, cognition, language, adaptive skills, or neurocognitive assessments (EEG and eye tracking). Quality was assessed using Risk of Bias 2 and GRADE. Nineteen publications from 12 studies reported on 715 infants and toddlers. There was low to moderate certainty evidence that clinician-assessed outcomes did not show significant treatment effects for: autism symptomatology (ADOS CSS: MD ?0.08, 95% CI ?0.61, 0.44, p?=?0.75), cognitive outcome (Mullen Scales of Early Learning-Early Learning Composite (MSEL-ELC): SMD 0.05, 95% CI ?0.19, 0.29, p?=?0.67), receptive language (MSEL?Receptive Language: SMD 0.04, 95% CI ?0.21, 0.3, p?=?0.74) or expressive language (MSEL-Expressive Language: SMD 0.06, 95% CI ?0.1, 0.23, p?=?0.45). Neurocognitive outcomes (EEG and eye tracking) were heterogeneous, with inconsistent findings. There is low to moderate certainty evidence that very early interventions have limited impact on neurodevelopmental outcomes by age 3?years.

VARCIN, Auteur Article en page(s) : p.490-501 Langues : Anglais (eng) Mots-clés : developmental psychology diagnosis early signs individual variability/heterogeneity infants psychometrics Index. décimale : PER Périodiques Résumé : We investigated whether a commonly used research assessment - the Autism Observation Scale for Infants (AOSI) - accurately measures autism behaviours among infants showing early signs of autism identified within the community. The AOSI is often included in studies tracking the development of infants at increased likelihood of autism, such as the infant siblings of diagnosed children. However, the suitability of this measure has not previously been tested with community-referred infants. We administered the AOSI with infants when aged 9 to 14 months and again 6?months later. Our researchers - independent of the AOSI development team and newly trained on this measure - were able to administer the brief interactive assessment and score it accurately. The infants' AOSI scores were linked to their scores on other established and validated clinical assessments, particularly at the second visit when average age was 18?months. Stronger correspondence of AOSI and other scores at this second visit suggests early autism behaviours are better established and more consistent by 18?months of age, even though these infants showed clear enough signs of possible autism to prompt referral to our study around 12?months of age. However, the moderate association of AOSI scores over time suggests that, like infant siblings - who mostly do not develop autism - community-identified infants showing early signs may also have variable developmental pathways in early life.
