Pitch processing in the human brain is influenced by language experience

  title={Pitch processing in the human brain is influenced by language experience},
  author={Jack Gandour and Donald Wong and Gary D. Hutchins},
POSITRON emission tomography (PET) was used in a cross-linguistic study to compare pitch processing in native speakers of English, a nontone language, with those of Thai, a tone language. When discriminating pitch patterns in Thai words, only the Thai subjects showed activation in the left frontal operculum. Activation of this region near the classically defined Broca's area suggests that the brain recognizes functional properties, rather than simply acoustic properties, of complex auditory… Expand
A Cross-Linguistic PET Study of Tone Perception in Mandarin Chinese and English Speakers
This cross-linguistic study compared tone perception in 12 native Mandarin speakers, who use tonal patterns to distinguish lexical meaning, with that of 12 native speakers of a nontone language, English, to determine whether neural mechanisms subserving pitch perception differ as a function of linguistic relevance.

Brain responses in the processing of lexical pitch-accent by Japanese speakers
Near-infrared spectroscopy showed that the responses to the pitch pattern change within the words were larger than those for the pure tones in the left temporoparietal region, indicating that the left language-related regions contribute to the processing of lexical pitch-accent in native Japanese speakers. Expand
A Crosslinguistic PET Study of Tone Perception
In studies of pitch processing, a fundamental question is whether shared neural mechanisms at higher cortical levels are engaged for pitch perception of linguistic and nonlinguistic auditory stimuli.Expand
Neural circuitry underlying perception of duration depends on language experience
Functional MRI data from Thai and English subjects collected in a speeded-response, selective attention paradigm demonstrate that encoding of complex auditory signals is influenced by their functional role in a particular language. Expand
Auditory Preattentive Processing of Speech Prosody in Lexical Tone : a Functional Imaging with Low Resolution Brain Electromagnetic Topography ( LORETA )
The present study investigated the preattentive perception of speech prosody changes in lexical tone as revealed by the low-resolution electromagnetic tomography (LORETA). The mismatch negativityExpand
Functional Heterogeneity of Inferior Frontal Gyrus Is Shaped by Linguistic Experience
Findings suggest that functional circuits engaged in speech perception depend on linguistic experience, and that storage and executive processes of working memory that are implicated in phonological processing are mediated in discrete regions of the left frontal lobe. Expand
Effects of language experience and stimulus context on the neural organization and categorical perception of speech
It is inferred that contextual influence on the CP for tones is determined by language experience and the frequency of pitch patterns as they occur in listeners' native lexicon, and "neurometric" functions derived from multidimensional scaling and clustering of source ERPs established. Expand
Chapter 87 – Processing Tone Languages
In tone languages, changes in pitch variations can signal differences in the lexical meaning of a word. We report advances in our understanding of the neurobiology of lexical tone at different stagesExpand
Development of Hemispheric Specialization for Lexical Pitch–Accent in Japanese Infants
The results suggest that the perceptual change in Japanese lexical pitch–accent may be related to a shift in functional lateralization from bilateral to left hemisphere dominance. Expand

A key issue for the study of language and the brain in the twenty-first century is the delineation of the neural substrate underlying the perception and production of prosody in relation toExpand


Neurobiology of speech perception.
The mechanisms by which human speech is processed in the brain are reviewed from both behavioral and neurobiological perspectives, and the separation of speech processing as a complex acoustic-processing task versus a linguistic task is separated. Expand
Neural mechanisms underlying melodic perception and memory for pitch
It is concluded that specialized neural systems in the right superior temporal cortex participate in perceptual analysis of melodies; pitch comparisons are effected via a neural network that includes right prefrontal cortex, but active retention of pitch involves the interaction of right temporal and frontal cortices. Expand
Rate of acoustic change may underlie hemispheric specialization for speech perception
Reducing the rate of acoustic change within syllables while keeping their phonemic characteristics constant significantly decreased the characteristic asymmetry in processing speech. Expand
The neural bases of prosody: Insights from lesion studies and neuroimaging
This paper reviews the major findings and hypotheses to emerge in the literature concerned with speech prosody. Both production and perception of prosody are considered. Evidence from studies ofExpand
The neural correlates of the verbal component of working memory
Comparisons of distribution of cerebral blood flow in these conditions localized the phonological store to the left supramarginal gyrus whereas the subvocal rehearsal system was associated with Broca's area, the first demonstration of the normal anatomy of the components of the 'articulatory loop'. Expand
A new brain region for coordinating speech articulation
All patients with articulatory planning deficits had lesions that included a discrete region of the left precentral gyms of the insula, a cortical area beneath the frontal and temporal lobes that seems to be specialized for the motor planning of speech. Expand
A two-route model of speech production. Evidence from aphasia.
Quantitative investigations of speech production deficits are reported in three aphasic patients, finding that in repetition tasks which required active semantic processing the conduction aphasics were facilitated and the transcortical motor aphasia impaired; in tasks whichrequired passive repetition the opposite pattern of dissociation was observed. Expand
Auditory temporal perception deficits in the reading-impaired: A critical review of the evidence
The phonological deficit of impaired readers cannot be traced to any co-occurring nonspeech deficits so far observed and is phonetic in origin, but that its full nature, origin, and extent remain to be determined. Expand
A specialization for speech perception.
The phonetic module has certain properties in common with modules that are "closed" (for example, sound localization or echo ranging in bats) and, like other members of this class, is so placed in the architecture of the auditory system as to preempt information that is relevant to its special function. Expand
The identification of affective-prosodic stimuli by left- and right-hemisphere-damaged subjects: all errors are not created equal.
The results of this and other studies suggest that rather than being lateralized to a single cerebral hemisphere in a fashion analogous to language, prosodic processes are made up of multiple skills and functions distributed across cerebral systems. Expand
