In this article we propose mechanisms that govern the processing of emotional information, particularly those involved in fear reduction. Emotions are viewed as represented by information structures in memory, and anxiety is thought to occur when an information structure that serves as program to escape or avoid danger is activated. Emotional processing is(More)
OBJECTIVE The purpose of the study was to test the relative and combined efficacy of clomipramine and exposure and ritual prevention in the treatment of obsessive-compulsive disorder (OCD) in adults. Serotonin reuptake inhibitors (SRIs) and cognitive behavior therapy by exposure and ritual prevention are both established treatments for OCD, yet their(More)
OBJECTIVE Three issues relevant to revising the DSM-III-R criteria for obsessive-compulsive disorder were examined in a field trial: 1) the requirement that symptoms of obsessive-compulsive disorder be viewed by the patient as excessive or unreasonable, 2) the presence of mental compulsions in addition to behavioral compulsions, and 3) ICD-10 subcategories.(More)
There exists a divide between findings from integrative neuroscience and clinical research focused on mechanisms of psychopathology. Specifically, a clear correspondence does not emerge between clusters of complex clinical symptoms and dysregulated neurobiological systems, with many apparent redundancies. For instance, many mental disorders involve multiple(More)
The prevailing view is that individuals with obsessive-compulsive disorder (OCD) are able to think rationally about their obsessive concerns and are thus able to recognize them as senseless. However, clinical observations indicate that at least some obsessive-compulsives do not regard their symptoms as unreasonable or excessive, and their ideas have been(More)
OBJECTIVE The purpose of this open clinical trial was to examine the efficacy of cognitive-behavioral treatment involving exposure and ritual prevention for pediatric obsessive-compulsive disorder (OCD). METHOD Children and adolescents with diagnosed OCD (N = 14) received cognitive-behavioral treatment, seven patients received intensive treatment (mean =(More)
Social neuroscience is a new, interdisciplinary field devoted to understanding how biological systems implement social processes and behavior. Social neuroscience capitalizes on biological concepts and methods to inform and refine theories of social behavior, and it uses social and behavioral constructs and data to inform and refine theories of neural(More)
We investigated selective processing of threat information in persons with posttraumatic stress disorder (PTSD) by using a modified Stroop procedure. Subjects were 15 rape victims with PTSD, 13 rape victims without the disorder, and 16 nontraumatized control subjects. They were asked to name the color of four types of words: specific threat (rape-related)(More)
