Three experiments with children between 5 and 7 years are described. It is shown that nominal predication of an unknown word by a superordinate term enables young children to make appropriate inferences concerning its attributes. The results are discussed in relation to semantic development and reasoning in the young child. (Author/RM)

The multiordinal use of terms requires the ability to distinguish essential relationships and attributes from incidental ones. Until the child reaches adolescence, his tendency to confuse incidental and affective factors with those crucial to word meaning hinders his use of terms at all levels of abstraction. Korzybski's theory of multiordinality…

This study examined the effects of certain contextual linguistic variables on the logical performance of subjects in grades 4, 6, and 12 of selected British Columbia schools as well as some theoretical problems underlying assessment of the development of logical abilities. The task consisted of 27 syllogistic problems based upon the information…

Longitudinal data on conversations recorded from 1 child between 18 and 27 months of age and 3 children between 27 and 62 months were analyzed to chart acquisition of the word "if" and of conditional inference. Within six months of speaking their first "if," children produced "ifs" at the same rate and forms as…

This paper attempts to specify the ways in which bilingualism might affect cognitive functioning. Two general ways, the "linguistic" and the "non-linguistic," are distinguished. Linguistic explanations explain the effects of bilingualism on cognition as a direct result of the fact that the bilingual has access to two verbal…

This paper examines whether language development can be understood epigenetically in the same manner and based on the same principles with which Piaget has analyzed intellectual-cognitive development generally. The study is subdivided into four parts: (1) some principles in Piaget's system (the epigenetic principle, the genetic circle, and the…

In order to investigate the hypothesis that the conceptualization of sequence precedes that of simultaneity in child development, and to explore the use of elicited imitation in studying lexical acquisition, 32 subjects between 3 and 5 years of age were asked to verbally imitate a list of sentences. The constructions combined simple and reverse…

Compared the use of conditional logic in adult-adult and adult-child conversation. Results indicated that conversation patterns and inferences were similar except that children made fewer independent inferences and shifts in taxonomic level and responded more frequently to socially controlling statements than did adults.

The range of meanings of "big" and "little" that mothers and their three children under age two expressed in relatively natural communication situations was studied. Longitudinal data from transcripts of conversations of middle-class mothers and their children were analyzed along with diary records kept by parents of their children's use of size…
