Anterior temporal involvement in semantic word retrieval: voxel-based lesion-symptom mapping evidence from aphasia
Myrna F. Schwartz,Daniel Y. Kimberg,Grant M. Walker,Olufunsho Faseyitan,Adelyn Brecher,Gary S. Dell,H. Branch Coslett,H. Branch Coslett +7 more
TL;DR: This study is the first to demonstrate a specific and necessary role for the left anterior temporal lobe in mapping concepts to words in production and hypothesize that this role consists in the conveyance of fine-grained semantic distinctions to the lexical system.
Journal ArticleDOI
The Dark Side of Incremental Learning: A Model of Cumulative Semantic Interference during Lexical Access in Speech Production.
TL;DR: A simple model of lexical retrieval in speech production that applies error-driven learning to its lexical activation network and suggests that competition during lexical selection is not necessary for semantic interference if the learning process is itself competitive.
Journal ArticleDOI
Localizing interference during naming: Convergent neuroimaging and neuropsychological evidence for the function of Broca's area
Tatiana T. Schnur,Myrna F. Schwartz,Daniel Y. Kimberg,Elizabeth A. Hirshorn,H. Branch Coslett,Sharon L. Thompson-Schill +5 more
TL;DR: This paper found that the posterior LIFG is necessary for resolution of competition in word production, and that the degree of activation of the LifG in normal speakers and damage to the LIFg in aphasic speakers was associated with performance on the production task.
Journal ArticleDOI
Power in Voxel-based Lesion-Symptom Mapping
TL;DR: General considerations for voxel-based methods are outlined, the use of a nonparametric permutation test adapted from functional neuroimaging is characterized, and methods for regional power analysis in lesion studies are presented.
Journal ArticleDOI
A Case-Series Test of the Interactive Two-Step Model of Lexical Access: Evidence from Picture Naming.
TL;DR: The authors proposed a model of picture naming that allows lesions to weaken semantic and/or phonological connections by coupling interactive feedback with two selection steps, which can explain the wide variation in individual naming response profiles and key facts about lexical and sublexical errors.
