Current views on the acquisition of PRO can roughly be divided into two areas: lexical and syntactic accounts. We present data on one verb, "decide," that yields data that not only differs from the data for other similar verbs with the same children, but does not lend itself easily to either type of account. Data from a sentence elicitation task…

Describes a study in which an extensive fuzzy boundary was identified within the adult extension of two exemplary object-words, "dog" and "ball." It is argued that there has been an underestimation in previous research of the degree of correspondence that exists between child and adult extension. (33 references) (GLR)

Reports a study which examines some of the properties of objects to determine whether the number of different examples of an object concept presented to infants influences concept learning and generalization and to discover whether children's behavior and language in relation to new objects influence learning the concept and generalization to new…

To test hypothesis that young children may be open to learning non-SVO structures with novel transitive verbs, 12 children in each of three age groups (2-year olds, 3-year olds, and 4-year olds) were taught novel verbs, one in each of three sentence positions: medial, final, and initial. Results suggest English-speaking children's acquisition of a…

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 overextensions in comprehension and production, using the preferential-looking model, in 99 children (ages 1;9 to 2;3) who were asked to find the referent that matched the label they were given in real and anomalous trials. Results confirm that overextensions in production are not diagnostic of children's underlying semantic…

Reviews theoretical arguments from a longitudinal study of 1 Dutch child (age 3;8.13 at start) for considering production as a source of input for analysis and presents empirical evidence supporting the output-as-input hypothesis for the blending of the Dutch words "wats" and "iets." Evidence suggests the child analyzed his own…
