Functional anatomy of speech perception and speech production: psycholinguistic implications.

چکیده

This paper presents evidence for a new model of the functional anatomy of speech/language (Hickok & Poeppel, 2000) which has, at its core, three central claims: (1) Neural systems supporting the perception of sublexical aspects of speech are essentially bilaterally organized in posterior superior temporal lobe regions; (2) neural systems supporting the production of phonemic aspects of speech comprise a network of predominately left hemisphere systems which includes not only frontal regions, but also superior temporal lobe regions; and (3) the neural systems supporting speech perception and production partially overlap in left superior temporal lobe. This model, which postulates nonidentical but partially overlapping systems involved in the perception and production of speech, explains why psycho- and neurolinguistic evidence is mixed regarding the question of whether input and output phonological systems involve a common network or distinct networks.

Dorsal and ventral streams: a framework for understanding aspects of the functional anatomy of language.

Despite intensive work on language-brain relations, and a fairly impressive accumulation of knowledge over the last several decades, there has been little progress in developing large-scale models of the functional anatomy of language that integrate neuropsychological, neuroimaging, and psycholinguistic data. Drawing on relatively recent developments in the cortical organization of vision, and ...

Relationship between Working Memory, Auditory Perception and Speech Intelligibility in Cochlear Implanted Children of Elementary School

Objectives: This study examined the relationship between working and short-term memory performance, and their effects on cochlear implant outcomes (speech perception and speech production) in cochlear implanted children aged 7-13 years. The study also compared the memory performance of cochlear implanted children with their normal hearing peers. Methods: Thirty-one cochlear impl...

Researching (Non) Fluent L2 Speakers’ Oral Communication Deficiencies: A Psycholinguistic Perspective

Fluency in a second language (L2) involves a quintessentially cognitive processing system that operates quickly and effectively. The perceived importance of researching fluency through a psycholinguistic lens has motivated the related L2 research to resort to current cognitive speaking-specific models. This study, drawing on Levelt’s (1999a) psycholinguistic model, probed the deficiency sources...

Correlation 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 ...
