TLDR
Results implicate separable neural regions in two different aspects of phonetic categorization, consistent with the view that these areas process the acoustic-phonetic details of speech to resolve a token's category membership.About:

Neural mechanisms for voice recognition
Attila Andics,Attila Andics,James M. McQueen,Karl Magnus Petersson,Viktor Gál,Viktor Gál,Gábor Rudas,Zoltán Vidnyánszky,Zoltán Vidnyánszky +8 more
TL;DR: Voice recognition is supported by neural voice spaces that are organized around flexible 'mean voice' representations, which are interpreted as effects of neural sharpening of long-term stored typical acoustic and category-internal values.

Tuning up the developing auditory CNS
Dan H. Sanes,Shaowen Bao +1 more
TL;DR: Behavioral and computational analyses may provide insights into how cellular and systems plasticity effects underlie the development of cognitive functions such as speech perception.

Theories of spoken word recognition deficits in aphasia: evidence from eye-tracking and computational modeling
TL;DR: T theoretical accounts that have the potential to explain the dynamics of spoken word recognition in aphasia and the possible roles of anterior and posterior brain regions in lexical processing and cognitive control are discussed.

The Neural Bases of the Lexical Effect: An fMRI Investigation
TL;DR: Modulation of activation as a function of the lexically biased shift in phonetic category boundary was observed in the STG bilaterally as well as in frontal and midline structures, suggesting that the lexical effect has at minimum a perceptual component, in addition to an executive decision-related component.

Effects of category learning on neural sensitivity to non-native phonetic categories
Emily B. Myers,Kristen A. Swan +1 more
TL;DR: Behavioral results suggest that for successful learners, categorization training led to increased discrimination accuracy for between-category contrasts with no concomitant increase for within- category contrasts, and support a view in which top–down information about category membership may reshape perceptual sensitivities via attention or executive mechanisms in the frontal lobes.

TL;DR: An inventory of 20 items with a set of instructions and response- and computational-conventions is proposed and the results obtained from a young adult population numbering some 1100 individuals are reported.

An integrative theory of prefrontal cortex function
Earl K. Miller,Jonathan D. Cohen +1 more
TL;DR: It is proposed that cognitive control stems from the active maintenance of patterns of activity in the prefrontal cortex that represent goals and the means to achieve them, which provide bias signals to other brain structures whose net effect is to guide the flow of activity along neural pathways that establish the proper mappings between inputs, internal states, and outputs needed to perform a given task.

The Cognitive Neurosciences
TL;DR: The fourth edition of The Cognitive Neurosciences continues to chart new directions in the study of the biologic underpinnings of complex cognition -the relationship between the structural and physiological mechanisms of the nervous system and the psychological reality of the mind as discussed by the authors.
Journal ArticleDOI
The TRACE model of speech perception.
TL;DR: The TRACE model, described in detail elsewhere, deals with short segments of real speech, and suggests a mechanism for coping with the fact that the cues to the identity of phonemes vary as a function of context.
