Due in part to its complex nature, there is still much to uncover in the investigation of the neural processes that contribute to synchronization between speakers and listeners during communication in the context of social cognition, specifically between native and nonnative English speakers and listeners. This study used a novel method of…

Purpose: The change/no-change procedure (J. E. Sussman & A. E. Carney, 1989), which assesses speech discrimination, has been used under the assumption that the number of stimulus presentations does not influence performance. Motivated by the tenets of the multiple looks hypothesis (N. F. Viemeister & G. H. Wakefield, 1991), work by R. F. Holt and…

Reexamines the history of the apprehension, consumption, and production of reality by means of the aural in light of developments in virtual reality technology. Suggests that, by acknowledging and examining its roots in aural media, the connections of virtual reality to the discourse of authenticity are made clear. (SR)

Different speakers may pronounce the same sounds very differently, yet listeners have little difficulty perceiving speech accurately. Recent research suggests that listeners adjust their preexisting phonemic categories to accommodate speakers' pronunciations ("perceptual learning"). In some cases, these adjustments appear to reflect general…

This study investigated the contributions of fundamental frequency, formant spacing, and glottal waveform to talker identification. The first two experiments focused on the effect of glottal waveform in the perception of talker identity. Subjects in the first experiment, 30 undergraduate students enrolled in an introductory psychology course,…

This study presents an empirical investigation of basic processes in the perception of speech sounds. The experimental methods applied have their roots in two different psycholinguistic research paradigms; i.e., "categorical perception" and "dichotic listening." In the categorical perception paradigm, listeners' categorization…

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…

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…

The results of three projects concerned with auditory word recognition and the structure of the lexicon are reported in this paper. The first project described was designed to test experimentally several specific predictions derived from MACS, a simulation model of the Cohort Theory of word recognition. The second project description provides the…

N. F. Viemeister and G. H. Wakefield's (1991) multiple looks hypothesis is a theoretical approach from the psychoacoustic literature that has promise for bridging the gap between results from speech perception research and results from psychoacoustic research. This hypothesis accounts for sensory detection data and predicts that if the "looks" at…

Summarizing research activities in 1989, this is the fifteenth annual report of research on speech perception, analysis, synthesis, and recognition conducted in the Speech Research Laboratory of the Department of Psychology at Indiana University. The report contains the following 21 articles: "Perceptual Learning of Nonnative Speech…

From the close of the nineteenth century and into the early part of the twentieth century, three aural technologies--the telephone, the phonograph, and the radio--were rapidly disseminated throughout the United States. These technologies brought to the population more aural information than it had ever experienced and created a new environment of…

In a previous study, subjects that heard a monaurally presented two-clause sentence immediately followed by a probe word (identical word recognition) were faster at recognizing the probe as a sentence word with their left ears than with their right ears. This result suggested that the right ear was particularly efficient at transforming…

Hearing in Noise Test (HINT) list equivalency was examined using 24 listeners (ages 60 to 70) with sensorineural hearing impairments. Four speech conditions were tested, including a quiet condition and three noise conditions. Results found that for the three noise conditions, all lists were within 2dB of the means, indicating list equivalency.…

Summarizing research activities from October 1978 to August 1979, this is the fifth 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…
