One of a series of semiannual reports, this publication contains 13 articles which report the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. Articles and their authors are as follows: "The Role of Contrast in Limiting Vowel-to-Vowel Coarticulation in Different…

All beginners at simultaneous interpreting falter at the flow of oral language, unaware that their short-term semantic flow of oral language, unaware that his short-term semantic memory can be managed more efficiently if used to store units of meaning rather than discrete words. Beginners must learn to listen for sense from the start and focus…

G. Wolford's perturbation model of letter identification is designed to account for identification errors of briefly presented characters. Its chief assumptions are that features are extracted in parallel, that some of these features become perturbed or mislocalized, and that mislocalizations are more likely to occur in the direction of the fovea…

When subjects utter a series of redundant sounds while memorizing word lists, performance is impaired and phonemic similarity effect is reduced. Experiments explored the influence of articulatory suppression on free recall; neither showed interaction between suppression and serial position. Recency effect may not reflect short-term phonemic store.…

Summarizing research activities from January 1977 to September 1978, this is the fourth annual report of research on speech processing conducted in the Department of Psychology at Indiana University. The report includes extended manuscripts, short reports, progress reports, and information on instrumentation developments and software support. The…

This study investigates the role of specific inhibitory processes in lexical ambiguity resolution. An attentional view of inhibition and a view based on specific automatic inhibition between nodes predict different results when a neutral item is processed between an ambiguous word and a related target. Subjects were 32 English speakers with normal…

In order to test hypotheses derived from the concept that grammatical, syntactic, semantic, and contextual cues affect the degree of reading comprehension in a visual display, the present investigation was undertaken using the French language. The subjects were approximately 30 college students in a second-semester elementary French course. Five…

Fourteen college students read passages displayed on a cathode-ray tube as their eye movements were monitored in a study that examined (1) whether letters that lie in the center of vision are used earlier in the fixation than letters further to the right, (2) how soon after a stimulus event that event can affect eye movement control, and (3) how…

Literature concerning human information processing is examined for its implications and extensions into the realm of input processing during second language learning. It is argued that learners can process input solely for meaning, and that once meaning can be accessed automatically, attention can be directed to certain "non-important" structures…

Three types of processes occur in language learning, each intricately connected with the others. Social processes are the steps by which learners and target language speakers create a social situation in which target language communication is possible and desired. Linguistic processes are the ways in which assumptions held by target language…

A study investigating the independence of linguistic abilities from each other, specifically the separability of syntax and semantics and the autonomy of syntactic abilities, is described. In the study, 30 individuals with Alzheimer's disease produced spontaneous conversations, completed sentences eliciting 16 grammatical forms, and when possible,…

A study was conducted to determine how a reader identifies and represents the major topics in a text and their interrelationships. Subjects, 56 college students, read two texts one sentence at a time. Each text contained 12 paragraphs that discussed six attributes of two major topics. The paragraphs on one text were organized by attribute, while…

A study investigated at what point during eye fixations visual information is used in furthering the reading process. The study identified two aspects of information processing: registration, in which a light pattern on the retina triggers a pattern of neural activity in the visula cortex; and utilization, in which the registered pattern has an…

Some of the metaphors that continue to guide educators' ways of understanding classroom life and education research have conceptual boundaries and limitations. These metaphors are referred to as Cartesian in order to locate them historically and within a cultural setting. The first type of metaphor serves as a conduit of language, in which…

The relation definition theory proposed in this paper is explicitly different from previous semantic memory theories since it is the first to make a relation's definition the basis of semantic processing. The paper suggests that this relation definition theory successfully predicts relation similarity on the basis of one key primary assumption:…
