Theory and research pertaining to relationships between oral and written communication offer support to seemingly contrary hypotheses regarding the development of informational adequacy in speech and in writing. Because the social cognitive demands of face-to-face interaction are less complex than those of prototypical written communication, younger children might be expected to display greater audience adaptation in speech. On the other hand, the process of encoding in writing facilitates certain cognitive operations, and, therefore, children might be expected to communicate more effectively in writing. Empirical studies warranting conflicting conclusions, however, have administered tasks that tap different communication functions, either explanatory or referential. The present study replicates and extends this previous research by administering referential and explanatory communication tasks in both speech and writing to children at three grade levels. In addition, an independent measure of social cognitive ability was administered. Results confirmed increasing differentiation with age between speech and writing, with fifth graders displaying greater informational adequacy in writing. Children's performance in written communication, rather than speech, revealed a dependency on social cognitive ability. Differences between referential and explanatory communication suggested by previous research were confirmed.

This study examines the acquisition of sex-neutral uses of masculine terms by English- and Spanish-speaking children. English and Spanish differ in that sex-neutral uses of masculine terms are much more common in the latter, and in that English is a natural-gender language, while Spanish is a grammatical-gender language. For these reasons, it was hypothesized that Spanish-speaking children might discover the neutral, unmarked interpretations of masculine terms earlier than their English-speaking counterparts, who might have difficulty in moving away from an early sex-based interpretation of such forms to their sex-neutral application. Data from 256 children failed to confirm the hypothesis. Subjects from both language groups appeared to pay little attention to gender marking outside the noun, and they both paid less attention to masculine gender markers than to feminine gender markers outside the noun.

Children with specific reading disability fail to understand some complex spoken sentences as well as good readers. This investigation sought to identify the source of poor readers' comprehension difficulties. Second-grade good and poor readers were tested on spoken sentences with restrictive relative clauses in two experiments designed to minimize demands on working memory. The methodological innovations resulted in a high level of performance by both reader groups, demonstrating knowledge of relative clause structure. The poor readers' performance closely paralleled that of the good readers both in pattern of errors and in awareness of the pragmatic aspects of relative clauses. The findings suggest that limitations in processing account for comprehension difficulties displayed by some poor readers in previous investigations.

Gierut (1986) presents a case in which a phonological intervention program is used to effect a phonemic split in a child with a highly restricted phonological system. A reanalysis of her data in this article suggests that the intervention program did not induce a phonemic split because the sounds in question were represented distinctively in the child's system prior to intervention. Three alternatives to Gierut's analysis are presented and discussed. It is argued that both relational and independent analyses of children's phonologies that include reference to perceptual skills and knowledge are necessary to reveal the structures and processes involved in phonological development.

This article refutes the reanalysis of a phonologically disordered child's use of fricatives as developed by Fey (1989) within a relational framework. Evidence in the form of nonsystematic correspondences between this child's substitution patterns and the target sound system is used to further establish the accuracy of the original independent generative analysis developed by Gierut (1986). This evidence supplements and supports the initial claims that this child exhibited a pattern of complementary distribution among the fricatives [f] and [s] and, moreover, the remediation program successfully induced a phonemic split.

In the experiment reported here, subjects heard the beginnings of spoken words, followed by increasingly larger segments of word-onset information until the words could be correctly identified. The likelihood of word identification at any given point was found to be an inverse power function of the number of words in a dictionary count that began with the same sounds as the stimulus. Subjects' prerecognition responses consisted of words drawn from a wide range of word frequencies. The variance in frequency decreased with increasing amounts of word-onset information. Results are discussed in terms of word-initial phonology as a trigger for response activation.
