Reciprocal Associations between Language Ability and Social Functioning Development in Pre-Verbal Autistic Children
Peer reviewed Peer reviewed
Direct linkDirect link
Devon R. Oosting; Mya S. Howard; Alice S. Carter – Journal of Autism and Developmental Disorders, 2024
Longitudinal research on language abilities and social functioning in young children suggests that gains in one domain affect gains in the other. However, few studies have examined inter-relations of language and social functioning jointly among young children diagnosed with autism spectrum disorder (ASD). Pre-verbal toddlers with ASD are a group…

Bussu, G.; Jones, E. J. H.; Charman, T.; Johnson, M. H.; Buitelaar, J. K.; Baron-Cohen, S.; Bedford, R.; Bolton, P.; Blasi, A.; Chandler, S.; Cheung, C.; Davies, K.; Elsabbagh, M.; Fernandes, J.; Gammer, I.; Garwood, H.; Gliga, T.; Guiraud, J.; Hudry, K.; Liew, M.; Lloyd-Fox, S.; Maris, H.; O'Hara, L.; Pasco, G.; Pickles, A.; Ribeiro, H.; Salomone, E.; Tucker, L.; Volein, A. – Journal of Autism and Developmental Disorders, 2018
We integrated multiple behavioural and developmental measures from multiple time-points using machine learning to improve early prediction of individual Autism Spectrum Disorder (ASD) outcome. We examined Mullen Scales of Early Learning, Vineland Adaptive Behavior Scales, and early ASD symptoms between 8 and 36 months in high-risk siblings (HR; n…

Postorino, Valentina; Fatta, Laura Maria; De Peppo, Lavinia; Giovagnoli, Giulia; Armando, Marco; Vicari, Stefano; Mazzone, Luigi – Journal of Autism and Developmental Disorders, 2015
Epidemiological studies have highlighted a strong male bias in autism spectrum disorder (ASD), however few studies have examined gender differences in autism symptoms, and available findings are inconsistent. The aim of the present study is to investigate the longitudinal gender differences in developmental profiles of 30 female and 30 male…

Hudry, Kristelle; Chandler, Susie; Bedford, Rachael; Pasco, Greg; Gliga, Teodora; Elsabbagh, Mayada; Johnson, Mark H.; Charman, Tony – Journal of Autism and Developmental Disorders, 2014
Many preschoolers with autism spectrum disorders (ASD) present relative lack of receptive advantage over concurrent expressive language. Such profile emergence was investigated longitudinally in 54 infants at high-risk (HR) for ASD and 50 low-risk controls, with three language measures taken across four visits (around 7, 14, 24, 38 months). HR…

Preschoolers with Autism Spectrum Disorder Followed for 2 Years: Those Who Gained and Those Who Lost the Most in Terms of Adaptive Functioning Outcome
Peer reviewed Peer reviewed

Hedvall, Åsa; Westerlund, Joakim; Fernell, Elisabeth; Norrelgen, Fritjof; Kjellmer, Liselotte; Olsson, Martina Barnevik; Carlsson, Lotta Höglund; Eriksson, Mats A.; Billstedt, Eva; Gillberg, Christopher – Journal of Autism and Developmental Disorders, 2015
Clinical predictors of 2-year outcome in preschoolers with ASD were studied in a population-based group of very young children with ASD (n = 208). Children who gained the most (n = 30) and lost the most (n = 23), i.e., increased or decreased their adaptive functioning outcome according to the Vineland Composite Score between study entry (T1) and…

Precursors to Social and Communication Difficulties in Infants At-Risk for Autism: Gaze Following and Attentional Engagement
Peer reviewed Peer reviewed
Direct linkDirect link
Bedford, Rachael; Elsabbagh, Mayada; Gliga, Teodora; Pickles, Andrew; Senju, Atsushi; Charman, Tony; Johnson, Mark H. – Journal of Autism and Developmental Disorders, 2012
Whilst joint attention (JA) impairments in autism have been widely studied, little is known about the early development of gaze following, a precursor to establishing JA. We employed eye-tracking to record gaze following longitudinally in infants with and without a family history of autism spectrum disorder (ASD) at 7 and 13 months. No group…

Prenatal Stress and Risk of Febrile Seizures in Children: A Nationwide Longitudinal Study in Denmark
Peer reviewed Peer reviewed

Li, Jiong; Olsen, Jorn; Obel, Carsten; Christensen, Jakob; Precht, Dorthe Hansen; Vestergaard, Mogens – Journal of Autism and Developmental Disorders, 2009
We aimed to examine whether exposure to prenatal stress following maternal bereavement is associated with an increased risk of febrile seizures. In a longitudinal population-based cohort study, we followed 1,431,175 children born in Denmark. A total of 34,777 children were born to women who lost a close relative during pregnancy or within 1 year…

Pry, Rene; Bodet, Joffrey; Pernon, Eric; Aussilloux, Charles; Baghdadli, Amaria – Journal of Autism and Developmental Disorders, 2007
This longitudinal study assessed multidisciplinary data on 219 children with autistic spectrum disorders from the median age of 5 (Time 1) to 8 years old (Time 2). The evolution of psychological and adaptive data was subjected to cluster analysis. Four clinically meaningful clusters emerged. The first group (21%) demonstrated the most important…

The Criteria for Early Use of Nonvocal Communication Systems with Nonspeaking Autistic Children.
Peer reviewed Peer reviewed
Nishimura, Bensaku; And Others – Journal of Autism and Developmental Disorders, 1987
Criteria to differentiate speaking from nonspeaking autistic preschool children were examined with 10 nonspeaking and 10 speaking children who were followed from age four-and-a-half to late childhood. Total developmental quotient; subscale scores of intellectual, selfcare, and motor ability; and several speech production factors distinguished…

Description of Semantic-Syntactic Relations in an Autistic Child.
Peer reviewed Peer reviewed
Layton, Thomas L.; Baker, Phyllis Strawson – Journal of Autism and Developmental Disorders, 1981
The longitudinal study investigated the language acquisition strategies employed over one and one-half years by an eight-year-old autistic child learning sign language. There were specific deviations in language development noted, in spite of providing the child with appropriate sign language training. (Author)

Brief Report: A Longitudinal Examination of the Communicative Gestures Deficit in Young Children with Autism.
Peer reviewed Peer reviewed
Camaioni, Luigia; Perucchini, Paola; Muratori, Filippo; Milone, Annarita – Journal of Autism and Developmental Disorders, 1997
Examined the use of protoimperative and protodeclarative pointing gestures in three children with autism (ages 26 to 53 months) at 5-month intervals over two years. Imperative or instrumental functions emerged early in all three; declarative or experience sharing functions emerged later in two subjects and not at all in the third. (DB)

Trajectories and Profiles of Adaptive Behavior in Males with Fragile X Syndrome: Multicenter Studies.
Peer reviewed Peer reviewed
Dykens, Elisabeth; And Others – Journal of Autism and Developmental Disorders, 1996
Two studies, 1 longitudinal with 29 subjects and 1 cross-sectional with 132 subjects, examined the adaptive trajectories and profiles of males with mental retardation caused by fragile X syndrome. Significant age-related gains were found in boys ages 1-10 but subjects ages 11-20 showed nonsignificant relations between age and adaptive skills. (DB)

Brief Report: Developmental Change in Theory of Mind Abilities in Children with Autism.
Peer reviewed Peer reviewed
Steele, Shelly; Joseph, Robert M.; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2003
A longitudinal study investigated developmental change in theory of mind among 57 children (ages 4-14) with autism. Theory of mind tests were administered on an initial visit and one year later. Data indicated significant developmental improvement in theory of mind ability, which was primarily related to the children's language ability. (Contains…
