Background: Understanding the different factors that determine vocabulary development in young children is essential for the diagnosis and rehabilitation of language disorders in children. Language development is closely related to other cognitive processes such as auditory verbal learning and memory. This research focuses on the development of a…

We examined the effects of classroom bilingual experience in children on an array of cognitive skills. Monolingual English-speaking children were compared with children who spoke English as the native language and who had been exposed to Spanish in the context of dual-immersion schooling for an average of 2 years. The groups were compared on a…

This study investigated the relationship between syntactic comprehension at the sentence level and text-level comprehension. The study isolated the specific contribution of syntax by asking whether sentence comprehension efficiency of difficult syntactic constructions explained variance in text comprehension after controlling for sentence…

Aim: The aim of this article was to explore the effect of duration of breastfeeding on neurocognitive development. Method: The long-term effect of breastfeeding on neurodevelopment was examined through a battery of neuropsychological tests in 1403 children (693 females, 710 males; mean age 11y 9mo [SD 6mo], range: 10y 3mo-12y 8mo) who were…

In three experiments, adults and 30-month-old children (1) selected a novel object as the referent for a novel term; (2) extended the new word to another exemplar; and (3) allowed the new word to preempt another novel label from applying to the just-named object. (BC)

A study examined how preschool children use information about linguistic contrast in learning new words. The 72 subjects were assigned to four groups to play a game. They were asked to get an unfamiliar item, one of nine swatches of different colors, shapes, and materials. In the first group, the children were told only one label (color, shape, or…

Twenty language-delayed children (age three to six) viewed a presentation incorporating object, action, attribute, and affective state words into a narrative script. In pre- and postviewing word comprehension measurements, subjects scored lower than children matched for chronological age and children matched for mean length of utterance.…

Sixteen sixth and seventh grade students with language disorders were taught 20 vocabulary items by means of categorization and verbal rehearsal, with half of the students encouraged to use a visual imagery learning strategy. Results suggest that visual imagery may enhance verbal encoding strategies. (Author/DB)

This paper explores the questions of how and why children learn names for things. The acquisition of reference is set within a broader discussion of linguistic representation, which defines language as a system functioning in a three-way relationship among the individual language user, the world of experience, and the social community. It is…

Undergraduate students using an imagery mnemonic mediating technique involving "keywords" to learn definitions of thirty unfamiliar words performed better on a 1-week delayed comprehension test, on at least half of the definitions, than those who read and copied definitions. Mnemonic mediating strategies worked better than nonmediating strategies…

Examined overregularization of irregular verb forms in children's language learning. Found that overregularization errors are relatively rare; occur at a constant rate; and are not correlated with the proportion of regular verbs in parents' or children's speech. Also found that a period of correct performance precedes the child's first error. (BC)

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,…

A study was conducted to determine if verbs were learned as easily as other words by primary school children. One hundred eight kindergarten children were divided into high, medium, and low I.Q. ranges and each range group was further divided--one group for each of three testing methods at each intelligence level. A list of words including 25…

A theory of the components of verbal intelligence is developed and tested in this series of experiments. After reviewing alternative theoretical frameworks for understanding verbal intelligence, a componential theory of verbal comprehension is proposed. This theory specifies the information-processing components, context cues, and mediating…

Tested the hypothesis that individual differences in immediate-verbal-memory span predict success in second-language vocabulary acquisition. In the two-session study, adult subjects learned 56 English-Finnish translations. Tested one week later, subjects were less likely to remember those words they had difficulty learning, even though they had…
