Neural mechanisms of selective visual attention.
TLDR
The two basic phenomena that define the problem of visual attention can be illustrated in a simple example and selectivity-the ability to filter out un­ wanted information is illustrated. Expand
Visual search and stimulus similarity.
TLDR
A new theory of search and visual attention is presented, which accounts for harmful effects of nontargets resembling any possible target, the importance of local nontarget grouping, and many other findings. Expand

TLDR
A view in which parallel, preattentive processes serve to segment the field into separate objects, followed by a process of focal attention that deals with only one object at a time is able to account for results taken to support both discrimination-based and space-based theories. Expand

TLDR
FMRI data indicate a key role for MD cortex in defining and controlling the parts of such programs, with focus on the specific content of a current cognitive operation, rapid reorganization as mental focus is changed, and robust separation of successive task steps. Expand
Common regions of the human frontal lobe recruited by diverse cognitive demands
Though many neuroscientific methods have been brought to bear in the search for functional specializations within prefrontal cortex, little consensus has emerged. To assess the contribution ofExpand
An adaptive coding model of neural function in prefrontal cortex
Key Points The prefrontal cortex is crucial for effective, organized behaviour. On the basis of data from functional neuroimaging in humans and single-cell electrophysiology in the behaving monkey,Expand
Prefrontal cortical function and anxiety: controlling attention to threat-related stimuli
TLDR
It is found that rostral ACC was strongly activated by infrequent threat-related distractors, consistent with a role for this area in responding to unexpected processing conflict caused by salient emotional stimuli and supports the proposal that anxiety is associated with reduced top-down control over threat- related distractors. Expand
Broad domain generality in focal regions of frontal and parietal cortex
TLDR
Functional MRI evidence from single-subject analyses for broad functional generality of a specific set of brain regions is presented: the same sets of voxels are engaged across tasks ranging from arithmetic to storing information in working memory, to inhibiting irrelevant information. Expand
Rehabilitation of executive functioning: An experimental–clinical validation of Goal Management Training
TLDR
Two studies assessed the effects of a training procedure, derived from Duncan's theory of goal neglect, on disorganized behavior following TBI and provided both experimental and clinical support for the efficacy of GMT toward the treatment of executive functioning deficits that compromise independence in patients with brain damage.
