Journal ArticleDOI
Executive function and fluid intelligence after frontal lobe lesions.
María Roca,Alice Parr,Russell Thompson,Alexandra Woolgar,Teresa Torralva,Nagui M. Antoun,Facundo Manes,John S. Duncan +7 more
TL;DR: Understanding of frontal lobe deficits may be clarified by separating reduced fluid intelligence, important in most or all tasks, from other more specific impairments and their associated regions of damage.
Journal ArticleDOI
Adaptive Coding of Task-Relevant Information in Human Frontoparietal Cortex
TL;DR: The results suggest a flexible neural system, exerting cognitive control in a wide range of tasks by adaptively representing the task features most challenging for successful goal-directed behavior.
Journal ArticleDOI
Fluid intelligence loss linked to restricted regions of damage within frontal and parietal cortex
Alexandra Woolgar,Alice Parr,Rhodri Cusack,Russell Thompson,Ian Nimmo-Smith,Teresa Torralva,María Roca,Nagui M. Antoun,Facundo Manes,John S. Duncan +9 more
TL;DR: Results suggest that coarse group comparisons cannot show the neural underpinnings of fluid intelligence tests, and deficits reflect the extent of damage to a restricted but complex brain circuit comprising specific regions within both frontal and posterior cortex.
Journal ArticleDOI
Goal neglect and Spearman's g: competing parts of a complex task.
John S. Duncan,Alice Parr,Alexandra Woolgar,Russell Thompson,Peter Bright,Sally G. Cox,Sonia J. Bishop,Ian Nimmo-Smith +7 more
TL;DR: The authors suggest that as novel activity is constructed, relevant facts, rules, and requirements must be organized into a "task model" and as this model increases in complexity, different task components compete for representation, and vulnerable components may be lost.
Journal ArticleDOI
Multi-voxel coding of stimuli, rules, and responses in human frontoparietal cortex
TL;DR: Stimulus-response mapping rule was the most strongly represented task feature, significantly coded in a lateral frontal region surrounding the inferior frontal sulcus, a more ventral region including the anterior insula/frontal operculum and the intraparietal sulcus.
