Children (2;10 to 4;7 years) taught passive sentences with forms employing animate patients could produce and comprehend passives better than children taught with forms employing inanimate patients. This indicates that "perspective" is the cognitive counterpart to the formal category of subject and that language acquisition is connected…

In an experiment in which preschool children were asked questions such as "Which box is taller than it is fat?" the results were interpreted to mean that the linguistic strategy of attending to the first clause is more resistant to change than the preference for simply choosing the largest object.

This study examines the relative contributions of rote-memorization, analogic formation and rule-operation in the production of plurals. Rule-operation was found to be important in that children producing responses characteristic of a given stage did not produce responses for later stages. Contributions of analogic formation and rote-memorization…

Children aged 2 - 4 were tested to determine the effects of plausibility on comprehension of negative statements. It was found that negatives about an exceptional item in an array, i.e. plausible negatives, were understood before implausible negatives. Other results are described and discussed. (Author/RM)

Describes a study done to determine whether the degree of children's familiarity with component words was related to (1) their ability to produce productive patterns as opposed to associative and grouping patterns, and (2) their ability to use broader scope rather than lexically based patterns.

The ability of children between the ages of two years and four years, eight months, to produce locative pre- or postpositions was investigated in English, Italian, Serbocroatian, and Turkish to discover universals of conceptual and communicative development. (Author/AM)

Two experiments indicating that children's linguistic generalizational biases change from a semantically-based system to a syntactical-structural system provide evidence for a semantic-relational bias in children's early grammars and support the notion that children's generalizational biases shift from a semantic-relational basis to a…

Study of a one-year-old's earliest use of prepositions found that spatial oppositions ("up-down") were learned first, and used in non-prepositional senses prior to prepositional usage. "With,""by,""to,""for,""at," and "of" were learned later and used to express case relationships and more often misused and omitted than the earlier-learned…

This study of the acquisition of kinship terms in English is a test of the hypothesis that lexical items are learned in their order of complexity and of the validity of relational analysis in predicting the order of the acquisition of kinship terms. Earlier studies of kinship terms, Piaget's in particular, are first discussed, as well as the…
