Landry, Oriane; Chouinard, Philippe A. – Journal of Cognition and Development, 2016
The broader autism phenotype (BAP) is a term applied to individuals with personality and cognitive traits that are similar to but milder than those observed in autism spectrum disorder (ASD). Subtle autistic traits in the core diagnostic domains of social communication and rigid behavior were described in family members of people with an ASD even…

McDonald, Nicole M.; Hyde, Carly; Choi, April Boin; Gulsrud, Amanda C.; Kasari, Connie; Nelson, Charles A., III; Jeste, Shafali S. – Infants and Young Children, 2020
Tuberous sclerosis complex (TSC) is a rare genetic syndrome that confers risk for neurodevelopmental disorders, including autism spectrum disorder and intellectual disability. Delays in social communication and early cognitive abilities are observable as early as 9 months of age in children with TSC; however, there have been no studies of early…

Hogan, Abigail L.; Caravella, Kelly E.; Ezell, Jordan; Rague, Lisa; Hills, Kimberly; Roberts, Jane E. – Journal of Autism and Developmental Disorders, 2017
No studies to date have prospectively examined early autism spectrum disorder (ASD) markers in infants with fragile X syndrome (FXS), who are at elevated risk for ASD. This paper describes the developmental profiles of eight infants with FXS from 9 to 24 months of age. Four meet diagnostic criteria for ASD at 24 months of age, and four do not.…

Caplan, Barbara; Blacher, Jan; Eisenhower, Abbey; Baker, Bruce L.; Lee, Steve S. – Grantee Submission, 2021
Emerging research suggests that caregiving environments and genetic variants independently contribute to social functioning in children with typical development or autism spectrum disorder (ASD). However, biologically plausible interactive models and complimentary assessment of mechanisms are needed to: (1) explain considerable social…

Wan, Ming Wai; Green, Jonathan; Scott, Jordan – Autism: The International Journal of Research and Practice, 2019
Social communicative precursors to autism spectrum disorder may influence how infants who are later diagnosed with autism spectrum disorder interact with their social partners and the responses they receive, thus bidirectionally influencing early social experience. This systematic review aimed to identify a developmental timeline for parent-infant…

Zampini, Laura; Zanchi, Paola – Journal of Intellectual & Developmental Disability, 2020
Background: The present study aimed at investigating mother-child dyadic co-regulation patterns in dyads with children with intellectual disability (ID). Method: 24 children paired for developmental age and vocabulary size (8 with chromosome 14 aberrations, 8 with Down syndrome, and 8 with typical development) and their mothers participated in the…

Chad; Hazlett, Heather C.; Emerson, Robert W.; Botteron, Kelly; Pandey, Juhi; Schultz, Robert T.; Dager, Stephen R.; Zwaigenbaum, Lonnie; Estes, Annette M.; Piven, Joseph – Child Development, 2018
Children's early language environments are related to later development. Little is known about this association in siblings of children with autism spectrum disorder (ASD), who often experience language delays or have ASD. Fifty-nine 9-month-old infants at high or low familial risk for ASD contributed full-day in-home language recordings.…

Lewis, Gary J.; Shakeshaft, Nicolas G.; Plomin, Robert – Journal of Autism and Developmental Disorders, 2018
Autism spectrum disorder (ASD) and autism-like traits are associated with deficits in face memory ability, although it is not yet clear whether this deficit reflects a specific aspect of the ASD/autism-like phenotype. We addressed this issue using a neurotypical sample of adolescent twins (N[subscript complete pairs] = 782) drawn from the Twins…

The objective of this study was to identify homogenous classes of young children with autism spectrum disorder (ASD) to improve phenotypic characterization. Children were enrolled in the Study to Explore Early Development between 2 and 5 years of age. 707 children were classified with ASD after a comprehensive evaluation with strict diagnostic…

Paterson, Sarah J.; Parish-Morris, Julia; Hirsh-Pasek, Kathryn; Golinkoff, Roberta Michnick – Journal of Cognition and Development, 2016
Various theorists have argued for the importance of a developmental approach to studying typical development (Karmiloff-Smith, 1998; Lerner, 1996; Lerner & Hood, 1986; Masten & Cicchetti, 2010; Overton, 2014; Overton & Lerner, 2012, 2014), and there are reasons to believe that this issue is even more critical to the study of…

Karp, Elizabeth A.; Ibañez, Lisa V.; Warren, Zachary; Stone, Wendy L. – Journal of Autism and Developmental Disorders, 2017
Parent-reported developmental concerns can be a first step toward further screening and intervention for children at risk for ASD. However, little is known about the extent to which parental well-being and child behavior contribute to parental concerns, especially in families who already have one child with ASD. This study included 54 parents and…

Hu, Valerie W. – Child Development, 2013
Autism spectrum disorders (ASD) are pervasive neurodevelopmental disorders that affect an estimated 1 in 110 individuals. Although there is a strong genetic component associated with these disorders, this review focuses on the multifactorial nature of ASD and how different genome-wide (genomic) approaches contribute to our understanding of autism.…

Roberts, Jane E.; McCary, Lindsay M.; Shinkareva, Svetlana V.; Bailey, Donald B., Jr. – Journal of Autism and Developmental Disorders, 2016
This study examined the developmental profile of male infants with fragile X syndrome (FXS) and its divergence from typical development and development of infants at high risk for autism associated with familial recurrence (ASIBs). Participants included 174 boys ranging in age from 5 to 28 months. Cross-sectional profiles on the Mullen Scales of…

Correia, F.; Café, C.; Almeida, J.; Mouga, S.; Oliveira, G. – Journal of Autism and Developmental Disorders, 2015
Autism spectrum disorder (ASD) is characterized by impaired social interaction and communication, restricted interests and repetitive behaviors. Fragile X E is associated with X-linked non-specific mild intellectual disability (ID) and with behavioral problems. Most of the known genetic causes of ASD are also causes of ID, implying that these two…

Uzun Cicek, Ayla; Sari, Seda Aybuke; Mercan Isik, Cansu – Journal of Mental Health Research in Intellectual Disabilities, 2020
Introduction: Intellectual disability (ID) is characterized by limitations in cognitive and adaptive functioning. The aim of this study is to examine sociodemographic characteristics, perinatal and childhood risk factors, and prevalence of psychiatric and biomedical comorbidities in children with ID. Methods: 260 patients with ID were included in…
