Early childhood learning of language has led some to postulate innate knowledge of an abstract symbolic linguistic system. However, if the child's abstract understanding initially requires concrete support in the form of agreement of the message with his nonlinguistic experience, the indication would be that the development of syntactic…

Examines relationship between literacy and intellectual development and the belief that literacy leads to higher forms of thought. Describes research findings among the Vai of Liberia, a people who invented a syllabic writing system to represent their own language.

Sixteen children (aged 14 to 26 months), who were reported by their parents to overextend, were tested for overextension in both language production and comprehension. The children were first asked to name each of a series of pictures of inappropriate exemplars of the words they were reported to overextend. Those words that were overextended, a…

Evidence is provided to refute the suggestion, made by Macnamara et al. (1976), that four-year-old children perform logical operations corresponding to formal logic upon the sentential components of implicative verbs to produce indirect implications. It is argued that children use past knowledge plus additional premises to derive indirect…

Presents a rebuttal to Hidi and Hildyard's (1976) criticism of Macnamara et al.'s (1976) assertion regarding the ability of four-year-old children to grasp implicatives and presuppositions. (AM)

The educational implications of Piaget's concept of intelligence provide a framework for the application of theory to educational practice. The uniqueness of individual learning is compared to stage-based teaching. Social interaction is viewed as one of the major forces in cognitive development. (JN)

Finds that various aspects of formal reasoning correlated significantly with mean t-unit lengths written by high school freshman boys, but not by freshman girls. Suggests that the reasoning tasks may have been biased against females. (RL)

The hypothesized ability of adult native speakers to understand linguistic ambiguity was tested. An approach developed to determine linguistic competence tested the ability of 90 participants in individual interviews to interpret sentences having the potential for multiple interpretations. The hypothesis was not supported by the data. A hierarchy…
