Infancy is a period of significant change for both the brain and behavior. During the first two years of life, the brain experiences an explosion of synaptic connections and myelination, alongside rapid development in motor, linguistic, and social behavioral abilities. Understanding the relationship between brain development and behavioral…

The current study examined how mothers' production of four types of internal state words at multiple ages across the second year in a free play context was related to their infants' acquisition of those words. Twenty-nine mother-infant dyads were videotaped for 18 minutes during free play when infants were 13 and 17 months old. Mothers' total and…

Purpose: To date, there is no tool for assessing early pragmatic development of Polish-speaking children. This study aimed to adapt to Polish a standardized parent report measure, the Language Use Inventory (LUI; O'Neill, 2009, in order to enable cross-cultural comparisons and to use the LUI-Polish to screen for pragmatic development in children…

This article describes the European Portuguese MacArthur-Bates Communicative Development Inventories short forms, the first published instruments for the assessment of language development in EP-learning infants and toddlers. Normative data from the EP population are presented, focusing on developmental trends for vocabulary learning, production…

This article presents results from a large population-based study of early communicative development in Norwegian children using an adaptation of the MacArthur-Bates Communicative Development Inventories, comprising 6574 children between 8 and 36 months. Data were collected via the Internet. In accordance with similar studies from other languages,…

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…

The first of three booklets in a series designed to help parents of handicapped children birth to 5 years old focuses on the communication process. A chart lists developmental milestones for both expressive and receptive language. Learning processes for communication (such as imitation, sensory knowledge, and memory) are reviewed. The bulk of the…

This study used longitudinal productivity criteria to establish the phonetic skill of 20 children (followed from 9 to 16 months). The number of specific consonants produced consistently across the months predicted referential lexical use at 16 months. Prior use of at least two supraglottal consonants characterized the children achieving…

Presents evidence that the supposed paradox in which infants find abstract patterns in speech-like stimuli whereas even some preschoolers struggle to find abstract syntactic patterns within meaningful language is no paradox. Asserts that all research evidence shows that young children's syntactic constructions become abstract in a piecemeal…

Asserts that the posited paradox between infancy and toddlerhood language was not eliminated by Tomasello and Akhtar's appeal to infants' robust statistical learning abilities. Maintains that scrutiny of their studies supports the resolution that abstracting linguistic form is easy for infants and that toddlers find it difficult to integrate…

A study involving 82 children with low vision evaluated the new developmental age levels and psychometric properties for the Reynell-Zinkin scales. The usefulness of age levels of the Reynell-Zinkin scales is discussed in relation to the aim of the scales, which is to have guidelines for assessment and developmental advice. (Contains references.)…

Examined children's generalization of familiar verbs to novel events. Findings reveal children aged 1;8 with the largest expressive vocabulary generalized the same verbs to actions with different agents, but not to actions different in outcome or manner of action and children aged 2;2 extended familiar action verbs to other actions different in…

Play behaviors of infants who had normal hearing or were deaf were observed during free play with their mothers, at ages 9, 12, and 18 months. Participants included 15 dyads of children who were deaf and mothers who were not, 15 dyads of children and mothers who were both deaf, and 15 dyads of children and mothers who both had normal hearing.…

Developmental behaviors are listed for children from birth to 6 years for gross motor, fine motor, self help, expressive and receptive language, psycho/social, and cognitive skills. Skills are broken down into 6-month intervals for the first year, and 1-year intervals from age 1 to 6. (CL)
