Article
Full-text available
This study investigated whether unattended speech is processed at a semantic level in dichotic listening using a semantic priming paradigm. A lexical decision task was administered in which target words were presented in the attended auditory channel, preceded by two prime words presented simultaneously in the attended and unattended channels, resp...
Article
Performing musicians invest thousands of hours becoming experts in a range of perceptual, attentional, and cognitive skills. The duration and intensity of musicians’ training – far greater than that of most educational or rehabilitation programs – provides a useful model to test the extent to which skills acquired in one particular context (music)...
Article
Full-text available
We investigated selective impairments in the production of regular and irregular past tense by examining language performance and lesion sites in a sample of twelve stroke patients. A disadvantage in regular past tense production was observed in six patients when phonological complexity was greater for regular than irregular verbs, and in three pat...
Article
This study investigated the development of children's skills in identifying ecologically relevant sound objects within naturalistic listening environments, using a non-linguistic analogue of the classic 'cocktail-party' situation. Children aged 7 to 12.5 years completed a closed-set identification task in which brief, commonly encountered environme...
Article
Full-text available
We report a patient with non-fluent Primary Progressive Aphasia who was premorbidly literate in two alphabetic scripts, Hungarian (L1) and English (L2). Testing was performed over a two-year period to assess the impact of progressive illness on oral reading and repetition of single words. Results showed significant decline in oral reading in both l...
Article
Full-text available
This study examined the effects of competing speech on auditory semantic comprehension using a dichotic sentence-word priming paradigm. Lexical decision performance for target words presented in spoken sentences was compared in strongly and weakly biasing semantic contexts. Targets were either congruent or incongruent with the sentential bias. Sent...
Article
Full-text available
It is widely accepted that hearing loss increases markedly with age, beginning in the fourth decade ISO 7029 (2000). Age-related hearing loss is typified by high-frequency threshold elevation and associated reductions in speech perception because speech sounds, especially consonants, become inaudible. Nevertheless, older adults often report additio...
Article
In a non-linguistic analog of the "cocktail-party" scenario, informational and contextual factors were found to affect the recognition of everyday environmental sounds embedded in naturalistic auditory scenes. Short environmental sound targets were presented in a dichotic background scene composed of either a single stereo background scene or a com...
Article
Recent studies indicate that the motor cortex is involved not only in the production of speech, but also in its perception. These studies have sparked a renewed interest in gesture-based theories of speech perception.
Article
How does the development and consolidation of perceptual, attentional, and higher cognitive abilities interact with language acquisition and processing? We explored children's (ages 5-17) and adults' (ages 18-51) comprehension of morphosyntactically varied sentences under several competing speech conditions that varied in the degree of attentional...
Article
In order to make sense of natural auditory environments, the developing child must learn to ‘‘navigate’’ through complex auditory scenes in order to segment out relevant auditory information from irrelevant sounds. This study investigated some of the informational and attentional factors that constrain environmental sound detection in auditory scen...
Article
This study examined the neurophysiological effects of acoustic degradation on auditory semantic processing. Event-related potentials were recorded to target words presented in a sentence context. Targets were semantically congruent or incongruent with the context, which was acoustically intact or low-pass filtered. In unaltered contexts, N400 ampli...
Article
Full-text available
Functional neuroimaging has demonstrated reduced activation correlated with behavioral priming effects, a finding generally interpreted in terms of facilitated retrieval of target items in the context of related primes. Without a neutral prime, however, one cannot separate facilitatory effects of related primes from inhibitory effects of unrelated...
Article
Full-text available
The most parsimonious account of language evolution is one where incremental, quantitative changes in primates' vocal tract, fiber pathways, and neuroanatomy converge with social and cultural developments. From this convergence arises the framework upon which complex language skills could build. Such an 'Emergentist' view emphasizes phylogenetic co...
Article
This study explored the role of attentional and perceptual factors in lexical access by examining the effects of acoustic distortion on semantic priming of spoken words by a sentence context. The acoustic manipulations included low-pass filtering, which was intended to interfere with the sensory encoding of the acoustic signal by reducing intelligi...
Article
Recent studies of lexical access in Broca's aphasics suggest that lexical activation levels are reduced in these patients. The present study compared the performance of Broca's aphasics with that of normal subjects in an auditory semantic priming paradigm. Lexical decision times were measured in response to word targets preceded by an intact semant...
Article
Selective deficits in aphasics' grammatical production and comprehension are often cited as evidence that syntactic processing is modular and localizable in discrete areas of the brain (e.g., Grodzinsky, 2000). In this paper, we review a large body of experimental evidence suggesting that morphosyntactic deficits can be observed in a number of apha...

Selective deficits in aphasic patients' grammatical production and comprehension are often cited as evidence that syntactic processing is modular and localizable in discrete areas of the brain (e.g., Y. Grodzinsky, 2000). The authors review a large body of experimental evidence suggesting that morpho-syntactic deficits can be observed in a number o...

Grodzinsky, 2000). The authors review a large body of experimental evidence suggesting that morphosyntactic deficits can be observed in a number of...
Article
This study explored whether natural acoustic variations as exemplified by either subphonetic changes or syllable structure changes affect word recognition processes. Subphonetic variations were realized by differences in the voice-onset time (VOT) value of initial voiceless stop consonants, and syllable structure variations were realized by vowel d...
Article
This study explored the prediction that local speaking rate context affects the perception of voice-onset time (VOT) in initial stop consonants not only for ambiguous stimuli at the category boundary, but also for good exemplars from the category center [Volaitis and Miller, J. Acoust, Soc. Am. 92, 723-735 (1992)]. Naturally produced exemplars of t...
Article
The relationship between acoustic-phonetic disturbances and lexical access was explored in an aphasic patient. M.L. had a restricted disturbance of phonemic discrimination that affected the discrimination of voicing contrasts in nonword stimuli. Despite this impairment, her discrimination of voicing contrasts in words and her comprehension of audit...
Article
This study explored the extent to which the acoustic manifestation of a phonetic feature is influenced by the linguistic role that the feature plays in the sound inventory of the particular language. To this end, we investigated the acoustic property associated with the feature [strident] in the production of bilabial and labiodental fricatives in...
Article
Full-text available
The utterances of one French and one American infant at 0;5, 0;8, 0;11, and 1;2 were transcribed and acoustically analysed for syllable duration and vowel formant values. Both general and language-specific effects emerged in the longitudinal study. Initial similarities in the consonantal repertoires of both infants, increasing control in producing...
Article
Full-text available
This study examined the effects of a competing signal on sentence-word priming using an auditory lexical decision paradigm. Previous studies have suggested that the facilitatory component of the sentential priming effect is particularly sensitive to acoustic distortions that reduce the perceptibility of the sentence context, whereas the inhibitory...
