The current study investigated the impact of birth order on vocabulary and social language development in 1338 first-born and 1049 s-born autistic youth (M age = 9.03 years, SD = 3.57; 86.4% male) from the Simons Simplex Collection. Frequentist and Bayesian analyses revealed mixed findings in language development. There were no differences in…

Purpose: Children with poor language tend to have worse psychosocial outcomes compared to their typically developing peers. The most common explanations for such adversities focus on developmental psychological processes whereby poor language triggers psychosocial difficulties. Here, we investigate the possibility of shared biological effects by…

In children with a hearing loss who receive cochlear implants (CIs) under the age of 2, regular assessments are conducted to monitor auditory and linguistic progress. However, the collection of authentic, representative, and reliable expressive language data on young children with CIs remains a challenge. The purpose of the study was to determine…

The present investigation explored the question of whether walking onset is related to infant language development. Study 1 used a longitudinal design (N = 44) to assess infant locomotor and language development every 2 weeks from 10 to 13.5 months of age. The acquisition of walking was associated with a significant increase in both receptive and…

Prospective questionnaire data from a longitudinal population sample on children with autism spectrum disorders (ASD), developmental delay, specific language impairment, or typical development (TD), were collected at ages eight, 12 and 24 months, via the Communication and Symbolic Behavior Scale Developmental Profile (CSBS)--Infant Toddler…

Background: Research has investigated late-talking toddlers because they are at great risk of continuing to experience language-learning difficulties once they enter school and hence are candidates for early intervention. It is also important to consider this group of children with regards to the immediate characteristics which are detrimental to…

The use of four types of psychological state words (physiological, emotional, desire, and cognitive) during mother-child play sessions at ages 3, 4, and 5 years was examined in 30 children diagnosed with delayed expressive language at 24-31 months and 15 age-matched comparison children with typical development. The children's mean length of…

The relationship between symbolic play and other domains, such as degree of autistic symptomatology, nonverbal cognitive ability, receptive language, expressive language, and social development, was investigated. The assessment files of 101 children with Autism Spectrum Disorder were studied. Nonverbal cognitive ability and expressive language…

This study aimed to investigate the relationships between abilities to initiate and respond to joint attention and symptoms of autism that have, and have not, been theoretically linked to joint attention. Participants were 51 boys and five girls with autistic disorder, aged between 2 years and 6 years 5 months. Measures of joint attention…

Four 17- to 21-month-old normally developing, and four 32- to 35-month-old language impaired children, classified as "referential" speakers or "expressive" speakers, produced linguistic features in clusters, and manifested play behaviors that were consistent with the children's pattern of lexical distribution.

Examines the impact of specific language delay (LD) on peer interaction in preschool children. Interaction between three groups of dyads (normals and normals; normals and LD children; and between LD children) were studied. Normal children were more likely to initiate interaction with non-responsive partners and to dominate the interaction.…

The monograph describes a systematic attempt to develop language behavior in a nonverbal autistic 4.5-year-old boy who was essentially unresponsive to environmental stimuli of any kind. The 45-session intervention focused on teaching him to attend, increasing his responsiveness to people, effecting discriminative responses to a variety of…

This report presents a revision of the Head Start Child Outcomes Framework (2000), renamed The Head Start Child Development and Learning Framework: Promoting Positive Outcomes in Early Childhood Programs Serving Children 3-5 Years Old. The Framework outlines the essential areas of development and learning that are to be used by Head Start programs…

The article describes language development techniques used with a 5-year-old autistic boy to increase his verbal behavior. Intervention consisted of 1.5 hour sessions four times a week over an 8-month period. The intervention focused on increasing nonvocal imitation, vocal imitation, verbal labeling, and verbal discrimination. Development of…

This study examined the relationship among language proficiency, behavior problems, and other areas of development in 36 children (ages 36 to 40 months). A strong association was found between deficiencies in both expressive and receptive language and behavioral difficulties. Specifically, deficits in expressive language at age 2 were more…
