Dorsomedial prefrontal cortex (dmPFC), dorsolateral prefrontal cortex (dlPFC), and inferior frontal gyrus (IFG) have all been implicated in resolving decision conflict whether this conflict is generated by having to select between responses of similar value or by making selections following a reversal in reinforcement contingencies. However, work distinguishing their individual functional contributions remains preliminary. We used functional magnetic resonance imaging to delineate the functional role of these systems with regard to both forms of decision conflict. Within dmPFC and dlPFC, blood oxygen level-dependent responses increased in response to decision conflict regardless of whether the conflict occurred in the context of …

The prevailing view of the medial temporal lobe (MTL) holds that its structures are dedicated to long-term declarative memory. Recent evidence challenges this position, suggesting that perirhinal cortex (PRc) in the MTL may also play a role in perceptual discriminations of stimuli with substantial visual feature overlap. Relevant neuropsychological findings in humans have been inconclusive, likely because studies have relied on patients with large and variable MTL lesions. Here, we conducted a functional magnetic resonance imaging study in healthy individuals to determine whether PRc shows a performance-related involvement in perceptual oddball judgments that is comparable to its established role in …

Recent research has suggested that the measure most commonly used to assess rumination, the Response Style Questionnaire (RSQ; L. D. Butler & S. Nolen-Hoeksema, 1994), may be heavily biased by depressive symptoms, thereby restricting the scope of research exploring this construct. This article offers a broader conceptualization of rumination, which includes positive, negative, and neutral thoughts as well as past and future-oriented thoughts. The first two studies describe the development and evaluation of the Ruminative Thought Style Questionnaire (RTS), a psychometrically sound measure of the general tendency to ruminate. Further, the scale is comprised of a single factor and shows …
