Between their second and fifth years, young children learn approximately 15 new words a day. For every word the child hears, he or she must choose the correct referent out of an infinite set of candidates. An important problem for developmental psychologists is to understand the principles that limit the child's hypotheses about word meanings. A…

The development of devices used to coin agent and instrument nouns in Hebrew was investigated among 60 children aged 3, 4, 5, 7, and 11. The prevalent word-formation device in Hebrew is the triconsonantal root combined with vowel patterns. Other available devices include suffixation, conversion, and compounding. Questions designed to elicit…

Catalogs new compound nouns in a recent German publication and suggests possibilities for using them as a springboard for vocabulary development in class. (VWL)

This study of early word learning focused on the status of object words in early vocabularies. Fourteen children were followed from nine months to two years of age, and monthly vocabulary growth was analyzed. Results indicated that object words represented approximately one-third, on average, of the different words the children learned. (TJQ)

This paper examines an under-studied component of deep vocabulary knowledge, affective meaning, which is used to convey attitudes. Two affective dimensions, evaluation and potency, are examined to determine whether they influence the vocabulary choices of native speakers of American-English in describing interpersonal interactions. In Experiment…

To examine effects of input and learner characteristics on morphology acquisition, 60 adult English speakers learned to inflect masculine and feminine Russian nouns in nominative, dative, and genitive cases. By varying training vocabulary size (i.e., type variability), holding constant the number of learning trials, we tested whether learners…

This study examined how writing (copying) target words and word fragments affects intentional second language (L2) vocabulary learning. English-speaking first-semester learners of Spanish attempted to learn 24 Spanish nouns via word-picture repetition in three conditions: (1) word writing, (2) fragment writing, and (3) no writing. After the…

Two strategies that children use to figure out new word meanings--attention to linguistic form class and the assumption of lexical contrast--were examined. It was found that very young children use both form class and lexical contrast to interpret new words. (PCB)

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)

This paper reports evidence from a longitudinal study in which children's attention to shape in a laboratory task of artificial noun learning was correlated with a rate shift in noun acquisitions. Eight children were tested in the laboratory at 3-week intervals beginning when they had less than 25 nouns in their productive vocabulary (M age=17…

Why are some words easier to learn than others? And what enables the eventual learning of the more difficult words? These questions were addressed for nouns using a paradigm in which adults were exposed to naturalistic maternal input that was manipulated to simulate access to several different information sources, both alone and in combination:…

This study explores the acquisition of complex words composed of both verbs and nouns through novel forms produced spontaneously by a French-English bilingual child. Diary recordings were kept by the child's mother from ages 2:8 to 5:0. The results showed little support for a proposed developmental sequence based on cross-sectional data e.g.,…

The role of the abstract triconsonantal root in the acquisition of Moroccan Arabic was investigated. Evidence from recorded speech samples of 32 Moroccan children between the ages of 3 and 6 is used to demonstrate that the abstract root plays a central role in both the nominal and verbal acquisition of the lexicon of Semitic languages and that the…

Eight 20- to 26-month-old children were exposed to 4 novel nouns in a game context over several weeks to determine whether, when, and in what ways the children would use them beyond their original linguistic forms. The majority were productive in their use of the nouns, indicating that the grammatical category for noun is operational by age 2.…

Two experiments explored the tendency of preschoolers to map novel nouns and verbs onto unfamiliar rather than familiar objects or actions. This disambiguation effect has been interpreted as evidence that youngsters expect object or action labels to be mutually exclusive. The effect was stronger for object than for action words. (MDM)
