Cognition and control in schizophrenia: a computational model of dopamine and prefrontal function
Behavioral deficits suffered by patients with schizophrenia in a wide array of cognitive
domains can be conceptualized as failures of cognitive control, due to an impaired ability to …

The construct of attention in schizophrenia
Schizophrenia is widely thought to involve deficits of attention. However, the term “attention”
can be defined so broadly that impaired performance on virtually any task could be …

Context-processing deficits in schizophrenia: converging evidence from three theoretically motivated cognitive tasks.
To test the hypothesis that the ability to actively represent and maintain context information is
a central function of working memory and that a disturbance in this function contributes to …

Context processing in older adults: evidence for a theory relating cognitive control to neurobiology in healthy aging.
A theory of cognitive aging is presented in which healthy older adults are hypothesized to
suffer from disturbances in the processing of context that impair cognitive control function …

Relation of prefrontal cortex dysfunction to working memory and symptoms in schizophrenia
OBJECTIVE: The dorsolateral prefrontal cortex has been implicated in both working memory
and the pathophysiology of schizophrenia. A relationship among dorsolateral prefrontal …

Context-processing deficits in schizophrenia: diagnostic specificity, 4-week course, and relationships to clinical symptoms.
Previous research on schizophrenia suggests that context-processing disturbances are one
of the core cognitive deficits present in schizophrenia. However, it is not clear whether such …
