Four experiments tested the hypothesis that the importance of linguistic labels for young children's conceptual organization stems from a privileged processing status of auditory input over visual input. Findings indicated that when auditory and visual stimuli were presented separately, 4-year-olds were likely to process both kinds of stimuli,…

Four computer-animated tasks were created to analyze the underlying structure of emerging phonological awareness at 3.5 years of age and to explore factors that influence children's (n=91) performance. The children were able to master tasks demanding identification, blending, and continuation of phonological units. Analysis supported two major…

Sixteen school-age children with specific language impairment (SLI) and 16 age-matched controls were tested for immediate recall of digits presented visually, auditorily, or audiovisually. Recall tasks compared speaking and pointing response modalities. SLI children showed small recency effects as well as an unusually poor recall when visually…

This experiment investigated relational complexity and relational shift in judgments of auditory patterns. Pitch and duration values were used to construct two-note perceptually similar sequences (unary relations) and four-note relationally similar sequences (binary relations). It was hypothesized that 5-, 8- and 11-year-old children would perform…

Negative priming refers to slowed down reactions when the distractor on one trial becomes the target on the next. Following two popular accounts, the effect might be due either to inhibitory processes associated with the frontal cortex, or to an ambiguity in the retrieval of episodic information. We used event-related brain potentials (ERPs) to…

A model of speech perception and production is suggested here which attempts to account for different rates of acquisition of perceptual and productive skill in the second language without assuming the existence of two separate second language grammars. (Author/KM)

Research efforts to model speech perception in terms of a processing system in which knowledge and processing are distributed over large numbers of highly interactive--but computationally primative--elements are described in this report. After discussing the properties of speech that demand a parallel interactive processing system, the report…

One of many aspects of the linguistic centrality of the spoken word is the "acoustic trigger" to conceptualization, the most significant primal trigger in human beings, which when activated results in contrast and comparison leading to symbolic conceptualization. The oral/aural mode, or vocal production and acoustic perception, is developmentally…

In teaching students how to write, the utilitarian aspect does not need to be ignored, but--more important--the imaginative, expressive aspect should be emphasized. Since all writing depends on the full resources of the imagination, students need to be taught how to recreate or vivify people, objects, scenes, and feelings. A process which helps…

Two experiments, a shadowing task and a mispronunciation-detection task, were performed to investigate the interactions between the data-driven primary speech perception process and the knowledge-driven word recognition process in the comprehension of continuous speech. Results are applied to an active direct access model of word recognition.…

Investigates whether 7- and 10-year-old children and adults are sensitive to their own and another listener's failure to understand literal and nonliteral (sarcastic) uses of utterances. (HOD)

The results suggested that all Ss used similar temporal frames of reference, but that hearing impaired Ss demonstrated developmental lags. (Author/DLS)
