The precedence effect (PE) describes an illusion produced when two similar sounds are delivered in quick succession (interclick delays of 2-8 msec) from sound sources at different locations so that only a single sound is perceived. The localization of the perceived sound is dominated by the location of the leading sound. If the delays are very short (< 1-2 msec), summing localization occurs and...

Three experiments asked whether phonotactic regularities not present in English could be acquired by adult English speakers from brief listening experience. Subjects listened to consonant–vowel–consonant (CVC) syllables displaying restrictions on consonant position. Responses in a later speeded repetition task revealed rapid learning of (a) first-order regularities in which consonants were rest...

A recently proposed auditory model is examined using simulated binaural masking level difference (BMLD) and dichotic pitch (Huggins and binaural edge pitch) stimuli. The model is based on calculating the instantaneous interaural level difference, i.e. the difference between the left and right ear neural signals. The model output produces pronounced maximum at the signal frequency with BMLD stim...

Landau-Kleffner Syndrome (LKS) is a rare, childhood neurological disorder characterized by a sudden or gradual development of acquired aphasia. This case study offers a unique opportunity to assess the changes in the auditory processing ability of a 12 year old male with LKS after two distinct auditory training programs, Fast ForWord® and Dichotic Interaural Intensity Difference (DIID) training...

Three experiments investigated the relationship between harmonic number, harmonic resolvability, and the perception of harmonic complexes. Complexes with successive equal-amplitude sine- or random-phase harmonic components of a 100- or 200-Hz fundamental frequency (f0) were presented dichotically, with even and odd components to opposite ears, or diotically, with all harmonics presented to both...

The ovarian hormones fluctuate during the menstrual cycle in women. Such fluctuation of sex hormones, in particular estrogen, is believed to affect the central conduction time in auditory function as well as the language lateralization in cognitive function. However, findings are inconsistent. The underlying mechanisms are also unclear. This paper examined if there was any relation between the ...

The classic [MN55] confusion matrix experiment (16 consonants, white noise masker) was repeated by using computerized procedures, similar to those of Phatak and Allen (2007). ["Consonant and vowel confusions in speech-weighted noise," J. Acoust. Soc. Am. 121, 2312-2316]. The consonant scores in white noise can be categorized in three sets: low-error set [/m/, /n/], average-error set [/p/, /t/, ...
