Choosing Our Words: Retrieval and Selection Processes Recruit Shared Neural Substrates in Left Ventrolateral Prefrontal Cortex

Hannah R. Snyder, Marie T. Banich, Yuko Munakata
2011 Journal of Cognitive Neuroscience  
Using improved measures, we find that shared neural substrates in left VLPFC support both selection and controlled retrieval, with no dissociation between mid and anterior regions.  ...  Our ability to respond in such underdetermined situations is supported by left ventrolateral prefrontal cortical ( VLPFC) regions, but there is active debate about whether these regions support (1) selection  ...  We thank Paula Villar, Kirsten Orcutt, and Luka Ruzic for assistance with data collection and analysis and members of the P50 center on Executive Function and Dysfunction, Cognitive Development Center,  ...

Neural aspects of second language representation and language control

Jubin Abutalebi
2008 Acta Psychologica  
A basic issue in the neurosciences of language is whether an L2 can be processed through the same neural mechanism underlying L1 acquisition and processing.  ...  In the present paper I review data from functional neuroimaging studies focusing on grammatical and lexicosemantic processing in bilinguals.  ...  The dorsolateral prefrontal cortex (Ba 9 and 46) would carry out sequential processing and self-monitoring functions, whereas the ventrolateral prefrontal areas 45 and 47 are engaged in a lower level function  ...

Controlled processing during sequencing

Malathi Thothathiri, Michelle Rattinger
2015 Frontiers in Human Neuroscience  
More recently, neuropsychological studies have suggested a specific role for the left premotor-prefrontal junction (BA 44/6) in selection between competing alternatives during sequencing.  ...  Therefore, we hypothesized that regions involved in controlled processing would show greater recruitment during the concurrent than the consecutive condition.  ...  ACKNOWLEDGMENTS We would like to thank Sam Buchl for assistance with preparing stimuli, and John VanMeter and Manish Khatiwada at the Georgetown CFMI center for their help with scanning related issues.  ...

Vicarious Neural Processing of Outcomes during Observational Learning

Elisabetta Monfardini, Valeria Gazzola, Driss Boussaoud, Andrea Brovelli, Christian Keysers, Bruno Wicker, Pier Francesco Ferrari
2013 PLoS ONE  
Results show that the neural systems involved in individual trial-and-error learning and in action observation and execution both participate in observational learning.  ...  Observational learning of associative rules relies on the ability to map the actions of others onto our own, process outcomes, and combine these sources of information.  ...  Author Contributions Conceived and designed the experiments: EM VG DB AB CK BW.

Corroborating behavioral evidence for the interplay of representational richness and semantic control in semantic word processing

Laura Bechtold, Christian Bellebaum, Paul Hoffman, Marta Ghio
2021 Scientific Reports  
Our corroborating evidence supports theories integrating representational richness and semantic control mechanisms as complementary mechanisms in semantic word processing.  ...  We found concreteness and contextual cues to facilitate word processing in a semantic judgment task with 55 healthy adults.  ...  The datasets generated during and/or analyzed during the current study are available from the corresponding author on reasonable request.  ...

Task dependent lexicality effects support interactive models of reading: A meta-analytic neuroimaging review

Chris McNorgan, Sarah Chabal, Daniel O'Young, Sladjana Lukic, James R. Booth
2015 Neuropsychologia  
Models of reading must explain how orthographic input activates a phonological representation, and elicits the retrieval of word meaning from semantic memory.  ...  An ALE meta-analysis explored lexicality effects directly contrasting words and pseudowords using the lexical decision task and overt or covert naming, which we assume rely most on the semantic and phonological  ...  Functional MRI investigating the neural substrates of word naming shows that English and Chinese show word regularity effects in a similar network of regions (Tan et al., 2001) .  ...
