Two experiments were conducted using match-to-sample methodologies in an effort to model lexical classes, which include both arbitrary and perceptual relations between class members. Training in both experiments used a one-to-many mapping procedure with nonsense syllables as samples and eight sets of abstract stimuli as comparisons. These abstract…

How do children determine the syntactic category of novel words? In this article we present the results of 2 experiments that investigated whether German children between 12 and 16 months of age can use distributional knowledge that determiners precede nouns and subject pronouns precede verbs to syntactically categorize adjacent novel words.…

The preschool years ages 3 and 4 are extremely important for social, emotional, physical, and cognitive development. The purpose of this article is to discuss the importance of preschool to heighten awareness and inform administrators, educators, families, and policymakers about the value of preschool and in particular preschool literacy…

Patterns of development in language and play for full term and preterm children from 6 to 54 months and the effects of maternal parenting strategies (i.e., maintaining attentional focus, use of directiveness) were examined. Significant risk differences in the growth of both language and play were found. The high risk children were more likely to…

Recurrence analysis is introduced as a means to investigate syntactic coordination between child and caregiver. Three CHILDES ( MacWhinney, 2000) corpora are analyzed and demonstrate coordination between children and their caregivers in terms of word-class n-gram sequences. Results further indicate that trade-offs in leading or following this…

Picture naming and picture identification tasks were used to investigate lexical-semantic skills in young children learning Hmong as a first language (L1) and English as a second language (L2). A total of 19 children, ages 3; 4 (years; months)-5; 2, participated in this study. Performance on lexical tasks was analyzed as a function of development…

This study examines the process of Japanese language maintenance or shift among children who were exposed to Japanese and English through the "one parent-one language" approach in Melbourne. The aim was to identify factors that correlate with successful and unsuccessful cases of Japanese language maintenance of such children. The data…

The purpose of the present study was to examine the developmental outcomes of children 7 years after their initial diagnosis. Children diagnosed with autism or PDD-NOS at age 2 received follow-up evaluations at age 9. Diagnostic stability was high, with 88 percent of the sample obtaining autism spectrum diagnoses at age 9. Cognitive scores…

Maternal ratings of self-efficacy and involvement in early intervention were compared across two groups of mothers with young children with Prelingual deafness: 24 mothers of children with hearing aids and 30 mothers of children with a cochlear implant. Although mothers of children with cochlear implants rated their child's early intervention…

Infants parse speech into word-sized units according to biases that develop in the first year. One bias, present before the age of 7 months, is to cluster syllables that tend to co-occur. The present computational research demonstrates that this statistical clustering bias could lead to the extraction of speech sequences that are actual words,…

This report summarizes findings from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development as effect sizes for exclusive maternal care and--for children in child care--type, quality, and quantity of care. Children (n = 1,261) were recruited at birth and assessed at 15, 24, 36, and 54 months.…

Drash and Tudor's argument that autism is a contingency-shaped disorder of verbal behavior is logical and consistent with behavioral principles, but the argument's premises have no direct empirical support and some conflicting evidence. The quantity and quality of research needed to support such a theory is compared to that found in the area of…

Williams syndrome (WS) is often cited as the prime example within developmental disorders of the dissociation of language from other cognitive skills, particularly from visuo-motor skills. This claim has been responsible for the challenges posed by this population to cognitive theories and to models of language acquisition. Two Hebrew-speaking…

This study examined the on-line processing of French sentences in a grammaticality judgment experiment. Three age groups of French children (mean age: 6;8, 8;6 and 10;10 years) and a group of adults were asked to detect grammatical violations as quickly as possible. Three factors were studied: the violation type: agreement violations (number and…

This study places the predictions of the bilingual interactive activation model (Dijkstra & Van Heuven, 1998) and the revised hierarchical model (Kroll & Stewart, 1994) in the same context to investigate lexical processing in a second language (L2). The performances of two groups of native English speakers, one less proficient and the other more…
