Purpose: This study investigated the effects of processing speed and phonological short-term memory (PSTM) on children's language performance. Method: Forty-eight school-age children with specific language impairment (SLI) and age peers completed auditory detection reaction time (RT) and nonword repetition tasks, the Clinical Evaluation of…

Creating compound nouns is the most productive process of Dutch morphology, with an interesting pattern of form variation. For instance, "staat" "nation" simply combines with "kunde" "art" ("staatkunde" "political science, statesmanship"), but needs a linking element "s" or…

Fifteen years ago, Pascual-Leone and colleagues used transcranial magnetic stimulation (TMS) to investigate speech production in pre-surgical epilepsy patients and in doing so, introduced a novel tool into language research. TMS can be used to non-invasively stimulate a specific cortical region and transiently disrupt information processing. These…

Augments Michael Studdert-Kennedy's state-of-the-art report on speech perception research (EJ 227 656) with comments on categorical perception of speech and nonspeech stimuli, speech perception in context, the role of prosody, and development/impairments of speech perception. Includes a summary of a discussion on speech perception research. (RL)

Notes that phonemic restoration is a powerful auditory illusion. Points out that when part of an utterance is replaced by another sound, listeners perceptually restore the missing speech. Several paradigms measure this illusion and explore its bottom-up and top-down bases. Findings reveal that acoustic properties of the replacement sound strongly…

Used a semantic and morpho-syntactic priming paradigm to examine at which processing stage the advantage of blind adults may arise. Concludes that the faster speech comprehension skills of blind adults may originate from a more efficient perceptual analysis rather than from a more extended use of semantic or morpho-syntactic context information.…

Findings from a study in which twins were given tests of onward repetition and auditory processing are discussed. Children with specific language impairments were impaired on both measures, but deficits had different origins. Auditory processing problems showed no evidence of genetic influence, whereas the nonword repetition deficit was highly…

The auditory word gating paradigm was used to examine the quality of the underlying phonological representations in dyslexic and average readers. Although dyslexic children showed age-related nonword and rapid naming deficits, they did not differ from the age-matched controls in the amount of acoustic-phonetic input required to identify sets of…

Phoneme identification with audiovisually discrepant stimuli is influenced by information in the visual signal (the McGurk effect). Additionally, lexical status affects identification of auditorily presented phonemes. The present study tested for lexical influences on the McGurk effect. Participants identified phonemes in audiovisually discrepant…

A popular theoretical account of developmental language and literacy disorders implicates poor auditory temporal processing in their etiology, but evidence from studies using behavioral measures has yielded inconsistent results. The mismatch negativity (MMN) component of the auditory event-related potential has been recommended as an alternative,…

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…

Examined the processing of speech and nonspeech sounds by 23 reading-disabled children. Children were required to identify and report the order of pairs of stimuli. Children had difficulty with very brief tones and stop consonant syllables at short interstimulus intervals. (SAK)

Children with developmental dyslexia appear to be insensitive to basic auditory cues to speech rhythm and stress. For example, they experience difficulties in processing duration and amplitude envelope onset cues. Here we explored the sensitivity of adults with developmental dyslexia to the same cues. In addition, relations with expressive and…

Recent neuroimaging studies and neuropsychological data suggest that there are regions in posterior auditory cortex that participate both in speech perception and speech production. An outstanding question is whether the same neural regions support both perception and production or whether there exist discrete cortical fields subserving these…

A study employed computational and experimental methods to address a number of issues related to the representation and structural organization of spoken words in the mental lexicon. Using a computerized lexicon consisting of phonetic transcriptions of 20,000 words, "similarity neighborhoods" for each of the transcriptions were computed.…
