Retrospective studies indicate 2 major classes of autism spectrum disorder (ASD) onset: early and later, after a period of relatively healthy development. This prospective, longitudinal study examined social, language, and motor trajectories in 235 children with and without a sibling with autism, ages 6-36 months. Children were grouped as: ASD…

Background: Recent models of the early emergence of autism spectrum disorder (ASD) propose that infant intrinsic risk susceptibilities in behaviour may be amplified by interaction within the early social environment into an increasingly atypical developmental trajectory. This study examines whether 6- and 12-month parent-infant interactions in…

There is a relative paucity of evidence examining the effectiveness of early intervention for young children with Autism Spectrum Disorder, in particular those delivered through educationally-based programmes. This study aimed to evaluate the real world effectiveness of a community-based autism-specific early learning and intervention programme in…

This study sought to determine the effects of using music and non-music interventions on the social responsive and avoidant behaviours of a preschool child with autism. A single-subject alternating treatment design was used in which two interventions were presented in a similar fashion except for the addition of music during the music condition.…

The present quasi-experimental study examines the outcomes for a group of 102 children diagnosed with an autism spectrum disorder at age 2 who attended an inclusive toddler program (described by Stahmer and Ingersoll, 2004) until age 3. Outcomes on standardized developmental assessments indicate significant improvement, with large effect sizes, in…

Previously, we adapted the Home Situations Questionnaire to measure behavioral non-compliance in everyday settings in children with pervasive developmental disorders. In this study, we further revised this instrument for use in autism spectrum disorder and examined its psychometric properties (referred to as the Home Situations…

Children who begin kindergarten with stronger skills learn faster than do those who enter with lower skills. Minority children tend to enter kindergarten already at a disadvantage, and the gap widens across time. However, little is known about cognitive development among American Indian young children. In this study, 110 American Indian infants…

Early intervention and early childhood special education professionals espouse the need for authentic assessment and meaningful family involvement, as well as relationship-based and routines-based intervention. This article explores a play-based approach to assessment that reflects these values by using the Transdisciplinary Play-Based Assessment,…

Autism spectrum disorders (ASD) have been gaining attention, partly as an example of unusual developmental trajectories related to early neurobiological differences. The present investigation addressed the process of learning new words to explore mechanisms of language delay and impairment. The sample included 21 typically developing toddlers…

Two studies examined relationships between play and other developmental domains. Found that play was correlated with adaptive and fine motor skills at 12 months and with language at 20 months. Between 14-36 months, play was correlated with all Mullen Scale of Early Learning subtests. Language expressive and visual expressive scales predicted play…
