Relative importance of appearance and potential function in children's object naming was examined. First, 16 children, taught novel names for unfamiliar objects, had to decide whether these applied to items that resembled the training objects in appearance or potential function. Then the name training procedure was revised so that equal emphasis…

The study reported here investigated the effects of using props to illustrate the meaning of sentences in a syntactic awareness task in which subjects were required to correct ungrammatical sentences. Children scored significantly higher in the props condition though the proportion of meaning-changing errors to total errors was not significantly…

Two studies are described that investigated preschool children's sensitivity to relative clauses as barriers to the movement of "wh" questions. A cross-sectional study and a longitudinal study conducted over the course of one year found that young children refused to extract "wh" questions from the ungrammatical site inside a…

Investigated the actionality effect in 48 French-speaking children (ages 5;0 to 7;11) by systematically varying the voice of the test sentences and the voice of the interpretive requests. The interaction between actionality, voice of sentence, and interpretive request revealed that the actionality effect depended on the type of task used to assess…

Evaluated the development of temporal location within a cross-linguistic experimental design. The research focused on the transition from a temporal system based on absolute temporal relations involving speech time and event time to a more complex system involving relative temporal relationships and reference time.

Two experiments were performed on the ability of children and adults to understand and produce locative verbs. Results confirm that children tend to make syntactic errors with sentences containing "fill" and "empty," encoding the content argument as direct object. (33 references) (JL)

Two experiments examined infants' reliance on object shape versus color for word generalization to animate and inanimate objects. Infants were taught labels for either novel vehicles or novel animals using preferential-looking procedure or an interactive procedure. Results of both experiments indicated that infants limited their word…

Investigated simple, appearance-predicted, and reality-predicted labelling in 36 3-, 4-, and 5-year olds. An age-related appearance-reality shift was observed in simple labelling. It is argued that younger children maintained the one-label-per-predicate pattern because of inflexible encoding; older children did so because of better understanding…

Two experiments suggest that adults and even preschoolers possess interpretive structures--particularly object structure--that are nonclassical in the sense that they can be used to resolve an apparent contradiction. Results further suggest that certain interpretive structures present themselves in reasoning about particular predicate-object…

Investigated the relationship between children's failures to produce unambiguous utterances and the mental effort demands in children (ages five, six, seven, and nine years), using finger-tapping and message production tasks, separately and simultaneously. Findings suggest that the relative effort requirements of communication decrease with…
