Background Previous work has documented lower vocalization rate and consonant acquisition delays in toddlers with autism spectrum disorder (ASD). We investigated differences in these variables at 12, 18, and 24 months in toddlers at high and low risk for ASD. Method Vocalization rate and number of different consonants were obtained from speech samples from a prospective study of infant siblin...

Toddlers can learn about the meanings of individual words from the structure and semantics of the sentences in which they are embedded. However, it remains unknown whether toddlers encode similarities among novel words based on their positions within sentences. In three experiments, two-year-olds listened to novel words embedded in familiar sentence frames. Some novel words consistently occurre...

We aimed to adapt the Modified Checklist for Autism in Toddlers to Turkish culture. The Modified Checklist for Autism in Toddlers was filled out independently by 191 parents while they were waiting for the well-child examination of their child. A high screen-positive rate was found. Because of this high false-positive rate, a second study was done in which the Modified Checklist for Autism in T...

Getting a toddler to comply with instructions is a common task for mothers, and one that may evoke different parenting styles as early as toddlerhood. In the present study, depressed adolescent mothers were classified by the “parenting styles” defined by Baumrind (1991) as authoritative, authoritarian, permissive, or disengaged based on their behavior during a structured play/compliance task wi...

The association between family socioeconomic status (SES) and the suspected autism spectrum disorder (ASD) status of 18-month-old toddlers was investigated using a population-based sample in Japan, which has a universal healthcare system and a mandatory health checkup system for toddlers. Questionnaires including SES measurements and modified checklist for autism in toddlers were mailed to all ...

Autism is often described as a disorder of neural synchronization. However, it is unknown how early in development synchronization abnormalities emerge and whether they are related to the development of early autistic behavioral symptoms. Here, we show that disrupted synchronization is evident in the spontaneous cortical activity of naturally sleeping toddlers with autism, but not in toddlers w...

OBJECTIVE To investigate if, and in what ways, communication impairments are present in toddlers (17-37 months) diagnosed with autism and Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS). METHODS Study 1-The scores of 20 toddlers with autism or PDD-NOS (i.e. ASD group) were compared to those of 20 typically-developing infants on the Communication sub-scale of the Baby and In...

This cross-cultural study investigates how maternal task assignment relates to toddlers' requested behavior and helping between 18 and 30 months. One hundred seven mother-child dyads were assessed in three different cultural contexts (rural Brazil, urban Germany, and urban Brazil). Brazilian mothers showed assertive scaffolding (serious and insistent requesting), whereas German mothers employed...

The authors examined the relations of maternal supportive parenting to effortful control and internalizing problems (i.e., separation distress, inhibition to novelty), externalizing problems, and social competence when toddlers were 18 months old (n = 256) and a year later (n = 230). Mothers completed the Coping With Toddlers' Negative Emotions Scale, and their sensitivity and warmth were obser...

The purpose of this study was to examine the effectiveness of an inhome parent management program for toddlers with behavior problems and developmental delays by comparing outcomes for a group of toddlers with developmental delays (n = 27) and a group of toddlers without developmental delays (n = 27). The majority of children lived in single parent, low-income homes. Results suggested that the ...
