Perceptual Category Judgment Deficits are Related to Prefrontal Decision Making Abnormalities in Schizophrenia
Previous studies of perceptual category learning in patients with schizophrenia generally demonstrate impaired perceptual category learning; however, traditional cognitive studies have often failed to address the relationship of different cortical regions to perceptually based category learning and judgments in healthy participants and patients with schizophrenia. In the present study, perceptu...

In contrast, how the human brain generates metacognitive awareness of task performance remains unclear. Here, we address this question by asking participants to perform perceptual decisions while providing ...
متن کاملThe role of ventromedial prefrontal cortex in decision making: judgment under uncertainty or judgment per se?
Ventromedial prefrontal cortex (VMF) is thought to be important in human decision making, but studies to date have focused on decision making under conditions of uncertainty, including risky or ambiguous decisions. Other lines of evidence suggest that this area of the brain represents quite basic information about the relative "economic" value of options, predicting a role for this region in va...
