This paper argues that if conclusions about children's grasp of logical concepts are to be reached and acceptable lines of research followed, then more precise definitions of the concept "logical necessity" must be formulated. The paper defines logical necessity as "the unconditional guarantee of truth that accompanies valid…

Analyzes concept formation in children based on the precepts of general semantics. (RB)

Two experiments were designed to assess children's ability to understand recursive structures of thinking which include thinking about contiguous people, thinking about action between people, thinking about thinking, and thinking about thinking about thinking. In Experiment I, 32 second, fourth, sixth, and eighth graders were tested on eight tasks…

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…

Past research on the development of referential communication abilities in children does not provide a basis for explaining precisely why communicative effectiveness increases. The common assumption is that developments in role-taking facilitate the child's ability to adapt to hearers. A reasonable alternative explanation is that a child's…

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)

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…

Hypothesizing that severely language delayed children lack sufficient understanding of causal structure to comprehend stories, a reading program concentrated on developing the causal reasoning of 10 children between the ages of 10 and 12 with a verbal intelligence quotient two to three years below average. Instructional activities in the…

As human understanding is largely metaphorical, what metaphor is, how children use it, and how they can be taught to use it more effectively are important educational concerns. A direct or indirect comparison between two apparently unlike things, metaphor consists of a topic, a vehicle of comparison, and ground--or traits--linking the topic and…

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.
