Dyslexia has frequently been related to atypical auditory temporal processing and speech perception. Results of studies emphasizing speech onset cues and reinforcing the temporal structure of the speech envelope, that is, envelope enhancement (EE), demonstrated reduced speech perception deficits in individuals with dyslexia. The use of this…

Here we report, for the first time, a relationship between sensitivity to amplitude envelope rise time in infants and their later vocabulary development. Recent research in auditory neuroscience has revealed that amplitude envelope rise time plays a mechanistic role in speech encoding. Accordingly, individual differences in infant discrimination…

The role of memory factors in the vowel discrimination of normal and at-risk 8-week-old infants was examined by studying the categorical versus continuous discrimination of very brief vowels in a nonnutritive sucking paradigm. Discrimination of the silent delay interval between the last familiar and the first novel stimulus was also examined.…

Experiments related to studying innate responsiveness to auditory stimuli in various infant organisms establish that animals have innate perceptual knowledge. (SA)

This study, with 161 children with and without language learning problems, tested the hypothesis that as children's language development matures, factor-analytic structural changes occur that are associated with measurements of fine-grained auditory discrimination, receptive vocabulary, receptive language, speech production, and 3 performance…
