Moberly, Aaron C.; Lowenstein, Joanna H.; Tarr, Eric; Caldwell-Tarr, Amanda; Welling, D. Bradley; Shahin, Antoine J.; Nittrouer, Susan – Journal of Speech, Language, and Hearing Research, 2014
Purpose: Several acoustic cues specify any single phonemic contrast. Nonetheless, adult, native speakers of a language share weighting strategies, showing preferential attention to some properties over others. Cochlear implant (CI) signal processing disrupts the salience of some cues: In general, amplitude structure remains readily available, but…

Nittrouer, Susan; Lowenstein, Joanna H.; Packer, Robert R. – Journal of Experimental Psychology: Human Perception and Performance, 2009
Much of speech perception research has focused on brief spectro-temporal properties in the signal, but some studies have shown that adults can recover linguistic form when those properties are absent. In this experiment, 7-year-old English-speaking children demonstrated adultlike abilities to understand speech when only sine waves (SWs)…

Nittrouer, Susan; Lowenstein, Joanna H. – Journal of Speech, Language, and Hearing Research, 2007
Purpose: It has been reported that children and adults weight differently the various acoustic properties of the speech signal that support phonetic decisions. This finding is generally attributed to the fact that the amount of weight assigned to various acoustic properties by adults varies across languages, and that children have not yet…

Nittrouer, Susan; Crowther, Court S. – Journal of Speech, Language, and Hearing Research, 1998
This study (with 16 children and 11 adults) examined an alternative to the Developmental Weighting Shift model which explains age-related differences in labeling of speech stimuli as due to increasing experience with word-internal structure. Findings rejected the alternative model, that changes in perceptual weighting strategies are due to…

Discriminability and Perceptual Weighting of Some Acoustic Cues to Speech Perception by 3-Year-Olds.

Nittrouer, Susan – Journal of Speech and Hearing Research, 1996
This study tested the hypothesis that there is a developmental shift in the perceptual weighting of acoustic parameters that results from experience with a native language. Comparison of 17 3-year olds and 16 adults found that age-related differences in auditory sensitivity did not fully account for age-related differences in perceptual weighting…
