The role of mirror neurons in speech perception and action word semantics
نویسنده
چکیده
The discovery of mirror neurons in the macaque monkey has ignited intense interest in motor theories of cognition, including speech and language. Here we examine two such claims, that the perception of speech sounds critically depends on motor representations of speech gestures (the motor theory of speech perception) and that the representation of action-related semantic knowledge critically depends on motor representations involved in performing actions. We conclude that there is strong evidence against the claim that speech perception critically depends on the motor system and that there is no conclusive evidence in support of the view that the motor system supports action semantics. We propose instead that motor-related activity during perceptual processes stem from spreading activation in sensory-motor networks that are critical for speech and language production.

Reflections on mirror neurons and speech perception.
The discovery of mirror neurons, a class of neurons that respond when a monkey performs an action and also when the monkey observes others producing the same action, has promoted a renaissance for the Motor Theory (MT) of speech perception. This is because mirror neurons seem to accomplish the same kind of one to one mapping between perception and action that MT theorizes to be the basis of hum...
متن کاملThe role of mirror neurons in speech and language processing.
The discovery of mirror neurons in the macaque frontal cortex (di Pellegrino, Fadiga, Fogassi, Gallese, & Rizzolatti, 1992; Gallese, Fadiga, Fogassi, & Rizzolatti, 1996; Rizzolatti & Arbib, 1998) has sparked renewed interest in the role of the motor system in receptive language processes. This interest has developed primarily around two logically independent, but sometimes conflated, ideas. One...
متن کاملSemantics of haq in the Glorious Quran
Meaning plays a very important role at all levels of linguistic analysis and in linguistics. We can say that the word itself and out of the chain of speech doesn’t show the true meaning. It should be in relation with other signs within the language that its meaning be relived. Quran, the precious word of Allah, contains words that take a variety of meanings in the syntactic and topical con...
متن کاملMirror Neurons and (Inter)subjectivity: Typological Evidence from East Asian Languages
Language is primarily constituted by action and interaction based on sensorimotor information. This paper demonstrates the nature of subjectivity and intersubjectivity through the neural mechanism and typological evidence of sentence-final particles from East Asian languages and extends to the discussion of the relationship between them. I propose that intersubjecivity is a kind of embedded or ...
متن کاملCorrelation between Auditory Spectral Resolution and Speech Perception in Children with Cochlear Implants
Background: Variability in speech performance is a major concern for children with cochlear implants (CIs). Spectral resolution is an important acoustic component in speech perception. Considerable variability and limitations of spectral resolution in children with CIs may lead to individual differences in speech performance. The aim of this study was to assess the correlation between auditory ...
