Experiments explored the hypothesis that immediate memory span varies with length of recalled words. Relationships between memory and word length, temporal duration, reading speed and visual and auditory presentation were investigated. Results are interpreted in terms of a phonemically-based store of limited temporal capacity with varied…

In two experiments using the Brown-Peterson memory paradigm, instructions to guess had small effects on recall, but sizeable effects on incidence of prior list intrustion. However, results indicate that proactive interference is primarily the result of inability to generate correct items, rather than confusion between present and previous items.…

This contradicts N. F. Johnson's arguments that word perception does not follow letter perception and that letter analysis awaits identification of the word as a unit. His experiments lack controls, and uncontrolled factors may contribute to his effects. Johnson's implications for prior-letter-processing models are contradicted. (CHK)

A study investigated the role of certain discourse and language processing factors in the production of narratives under controlled conditions. Subjects watched a short segment from a movie and then narrated the events to a researcher. The narrations were taped, transcribed, and analyzed in terms of such factors as: (1) the number and types of…

One of a series of semiannual reports, this publication contains 12 articles which report the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. The titles of the articles and their authors are as follows: "Coarticulatory Organization for Lip-rounding in Turkish and…

This document presents a study of natural language understanding of computer programs. In the study, the performance of IRUS, a natural language query system designed to interface with a database, was compared with the performance of preschool and early elementary school children in answering questions about a specific database. Questions used in…

A line of reasoning used in recent research on language acquisition assumes that a child acquiring the language has only two reliable sources of information available about the target grammar: a set of grammatical principles and the primary data of the language spoken around him. A third kind of evidence, negative evidence, would be helpful but is…

The application of the "back-propagation" learning algorithm to the task of determining the right set of features corresponding to the words in an input sentence is described. Features that are specific to particular nouns and verbs, that indicate whether a nominal constituent is singular or plural, definite or indefinite, and that…

The role of court judges as linguists is discussed. Linguistic issues arise in courts when lawyers attempt to convince a court that a statute, insurance policy, or contract should be interpreted as favoring their own client's interests, with respect to resolving a dispute that depends on the proper construal of a particular document. An…

A study investigated children's hypotheses about the meanings of novel verbs on the child's first exposure to the verb. The study focused on the properties (action, result, or instrument) ascribed to the verbs before any information was given about word meaning. Subjects were 3-year-olds, 5-year-olds, and adults. The stimuli were six sets of…

Children's ability to learn aspects of their language in the absence of supportive evidence is discussed. Specifically, the learnability of null subjects in languages in which they appear is examined when indirect negative evidence is present. It is concluded that parameters such as the null subject parameter may not generate languages, strictly…

The utility of negative evidence as input for grammar construction in second language learning is examined. Three issues are dealt with in this paper: (1) the arguments for and against negative evidence in first and second language acquisition are paralleled; (2) the question is situated within the larger issues of learner end-products and the…

A survey of the current research on readability formulas is presented in this paper, which distinguishes this research from research on the more general questions that surround formulas: What features of a text, particularly the language it is written in, make the text easy or difficult to read? and, What will predict that readers with particular…

A study was conducted to test an hypothesis relating semantic structures to cognitive development, specifically that the mean number of associative complexes used by a group of children will be significantly greater than the mean number of associative complexes used by a group of adolescents. The word game "Password" provided a simulation of a…

Recent research in adult pronunciation of foreign languages has assigned a significant role to affective variables. It has been shown that certain language functions, including many aspects of pronunciation, are handled by the right brain hemisphere. An experiment was conducted to study the extent to which the right hemisphere might be activated…
