Much research has explored developing sound representations in language, but less work addresses developing representations of other sound patterns. This study examined preschool children's musical representations using two different tasks: discrimination and sound--picture association. Melodic contour--a musically relevant property--and…

A recent study has shown that congenitally blind adults, who have never had visual experience, are impaired on an auditory spatial bisection task (Gori, Sandini, Martinoli, & Burr, 2014). In this study we investigated how thresholds for auditory spatial bisection and auditory discrimination develop with age in sighted and congenitally blind…

The influence of listener's expertise and sound identification on the categorization of environmental sounds is reported in three studies. In Study 1, the causal uncertainty of 96 sounds was measured by counting the different causes described by 29 participants. In Study 2, 15 experts and 15 nonexperts classified a selection of 60 sounds and…

Purpose: Infants have a good ability to detect brief silent gaps between 2 short identical sound markers (within-channel gap detection), with thresholds between 2 and 11 ms. The present experiment traces the development of temporal resolution for between-channel gaps (i.e., gaps delineated by spectrally disparate markers). This ability appears…

By examining the relations among sections of the fundamental frequency contour used in judging an utterance as a question or statement, the experiment described in this report seeks a more detailed understanding of auditory-linguistic interaction in the perception of intonation contours. The perceptual process may be divided into stages (auditory,…

An experiment which measures the foreignness of selected languages with reference to each other, to native languages of listeners, and to listeners' language experience is described. The procedure involves the tape recordings of 50 sentences in the native languages of 10 selected speakers. The second major stage involves playback to listener…

The experiments described in this report seek to investigate the characteristics of speech perception using an approach which considers the development of the perception of "voicing," both as it occurs naturally and as it might occur in the laboratory. Investigating voicing discrimination and perception training among adults, infants, and…

This report is one of a regular series on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. Manuscripts and extended reports cover the following topics: iconic storage, voice-timing perception, oral anesthesia, laryngeal function, electromyography of speech production,…
