Direct linkHatch, Burt; Iosif, Ana-Maria; Chuang, Annie; de la Paz, Leiana; Ozonoff, Sally; Miller, Meghan – Journal of Autism and Developmental Disorders, 2021
Diminished response to name, a potential early marker of autism spectrum disorder (ASD), may also indicate risk for other disorders characterized by attention problems, including attention-deficit/hyperactivity disorder (ADHD). Using a familial risk design, we examined whether response to name ability at 6, 12, 18, 24, and 36 months of age…

Wu, Chin-Chin; Chu, Ching-Lin; Stewart, Lydia; Chiang, Chung-Hsin; Hou, Yuh-Ming; Liu, Jiun-Horng – Journal of Autism and Developmental Disorders, 2020
The present longitudinal study examined the utility of the screening tool for autism in 2-year-olds (STAT) in detecting autism spectrum disorder (ASD) in toddlers who are less than 24 months of age. The study sample, which consisted of 119 toddlers with developmental problems, were assessed when they were between 16 and 24 months of age (Time 1)…

Shire, Stephanie Y.; Shih, Wendy; Chang, Ya-Chih; Bracaglia, Suzanne; Kodjoe, Maria; Kasari, Connie – Journal of Autism and Developmental Disorders, 2019
Intervention research is increasingly conducted in community settings, however it is not clear how well practices are sustained locally or how children progress once external research support is removed. Two school-year cohorts of toddlers with autism (year 1: n = 55, year 2: n = 63) received Joint Attention, Symbolic Play, Engagement, and…

Davidson, Meghan M.; Ellis Weismer, Susan – Journal of Autism and Developmental Disorders, 2017
This study examined the extent to which a discrepant comprehension-production profile (i.e., relatively more delayed comprehension than production) is characteristic of the early language phenotype in autism spectrum disorders (ASD) and tracked the developmental progression of the profile. Our findings indicated that a discrepant…

Gangi, Devon N.; Boterberg, Sofie; Schwichtenberg, Amy J.; Solis, Erika; Young, Gregory S.; Iosif, Ana-Maria; Ozonoff, Sally – Child Development, 2021
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…

Lawson, Lauren P.; Joshi, Rucha; Barbaro, Josephine; Dissanayake, Cheryl – Journal of Autism and Developmental Disorders, 2018
Relatively few studies have examined gender differences in infants and toddlers, and most focus on clinically referred samples or high-risk infant cohorts. The current study aimed to examine gender differences in early autism manifestations and cognitive development in a community-ascertained sample. In total, 46 males and 21 females with ASD were…

Tonnsen, Bridgette; Scherr, Jessica; Reisinger, Debra; Roberts, Jane – Journal of Autism and Developmental Disorders, 2017
Studying anxiety in neurogenetic syndromes may inform the intersection of biological and developmental risks, facilitating effective and targeted interventions. We longitudinally examined stranger fear in infants and toddlers with fragile X syndrome (FXS; n = 46) and typical controls (n = 33), as well as associations between observed stranger fear…

Barbaro, Josephine; Dissanayake, Cheryl – Autism: The International Journal of Research and Practice, 2017
Autism spectrum disorder diagnoses in toddlers have been established as accurate and stable across time in high-risk siblings and clinic-referred samples. Few studies have investigated diagnostic stability in children prospective identified in community-based settings. Furthermore, there is a dearth of evidence on the individual behaviours that…

Özçaliskan, Seyda; Adamson, Lauren B.; Dimitrova, Nevena; Baumann, Stephanie – Journal of Cognition and Development, 2017
Typically developing (TD) children refer to objects uniquely in gesture (e.g., point at a cat) before they produce verbal labels for these objects ("cat"). The onset of such gestures predicts the onset of similar spoken words, showing a strong positive relation between early gestures and early words. We asked whether gesture plays the…

LeBarton, Eve Sauer; Iverson, Jana M. – International Journal of Language & Communication Disorders, 2016
Background: Nonverbal communication deficits are characteristic of autism spectrum disorder (ASD) and have been reported in some later-born siblings of children with ASD (heightened-risk (HR) children). However, little work has investigated gesture as a function of language ability, which varies greatly in this population. Aims: This longitudinal…

Kamio, Yoko; Haraguchi, Hideyuki; Stickley, Andrew; Ogino, Kazuo; Ishitobi, Makoto; Takahashi, Hidetoshi – Journal of Autism and Developmental Disorders, 2015
To determine the best discriminative items for identifying young children with autism spectrum disorders (ASD), we conducted a secondary analysis using longitudinal cohort data that included the Japanese version of the 23-item modified checklist for autism in toddlers (M-CHAT-JV). M-CHAT-JV data at 18 months of age and diagnostic information…

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…

Özçaliskan, Seyda; Adamson, Lauren B.; Dimitrova, Nevena – Autism: The International Journal of Research and Practice, 2016
Research with typically developing children suggests a strong positive relation between early gesture use and subsequent vocabulary development. In this study, we ask whether gesture production plays a similar role for children with autism spectrum disorder. We observed 23 18-month-old typically developing children and 23 30-month-old children…

Armstrong, Rebecca; Whitehouse, Andrew J. O.; Scott, James G.; Copland, David A.; McMahon, Katie L.; Fleming, Sophie; Arnott, Wendy – Journal of Autism and Developmental Disorders, 2017
The current study examined the relationship between early language ability and autistic-like traits in adulthood, utilising data from 644 participants from a longitudinal study of the general population. Language performance at 2 years was measured with the Language Development Survey (LDS), and at 20 years the participants completed the…

Zhou, Vanessa; Munson, Jeffrey A.; Greenson, Jessica; Hou, Yan; Rogers, Sally; Estes, Annette M. – Autism: The International Journal of Research and Practice, 2019
Little is known about outcomes of early intervention for children with autism spectrum disorder reared in bilingual homes. There are concerns that social communication deficits among children with autism spectrum disorder may reduce the developmental benefits of early intervention for children with autism spectrum disorder raised in bilingual…
