Productivity is a central concept in the study of language and language acquisition. As a test case for exploring the notion of productivity, we focus on the noun slots of verb frames, such as __"want"__, __"see"__, and __"get"__. We develop a novel combination of measures designed to assess both the flexibility and…

Previous research has reported that bilingual children sometimes produce mixed noun phrases with "correct" gender agreement--as in "der dog" ("der" being a masculine determiner in German and the German word for "dog", "hund", being masculine as well). However, these could obviously be due to chance or to the indiscriminate use of a default…

The two main models of children's acquisition of inflectional morphology--the Dual-Mechanism approach and the usage-based (schema-based) approach--have both been applied mainly to languages with fairly simple morphological systems. Here we report two studies of 2-3-year-old Polish children's ability to generalise across case-inflectional endings…

Using a preferential looking methodology with novel verbs, Gertner, Fisher and Eisengart (2006 ) found that 21-month-old English children seemed to understand the syntactic marking of transitive word order in an abstract, verb-general way. In the current study we tested whether young German children of this same age have this same understanding.…

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.…

Examined 2-year-olds' comprehension and production of novel nouns, verbs, or actions at 3 intervals after training conducted in massed or distributed exposures. Found that for comprehension, children learned all item types in all training conditions at all retention intervals. Production was better for nonverbal actions than for either word type…
