Previous lesion and neuroimaging studies have shown that the frontal lobes play an important role in response inhibition. In the present study event-related functional near-infrared spectroscopy (NIRS) was applied to investigate cerebral blood oxygenation in the right and left prefrontal cortex (PFC) in 15 male participants during the performance of a(More)
BACKGROUND There is evidence that exerting self-control during alcohol craving can diminish performance on subsequent tasks that require self-control. Based on the resource depletion model (Muraven and Baumeister, 2000), we examined the influence of alcohol cue exposure on detoxified alcohol-dependent patients' ability to inhibit ongoing responses.

BACKGROUND Since its first publication, the Clinical Global Impression Scale (CGI) has become one of the most widely used assessment instruments in psychiatry. Although some conflicting data has been presented, studies investigating the CGI's validity have only rarely been conducted so far. It is unclear whether the improvement index CGI-I or a difference(More)
In the course of daily living, changing environmental demands often make our actions, once initiated, unnecessary or even inappropriate. Under such circumstances, the ability to inhibit the obsolete action and to update behavior can be of vital importance. Previous lesion and neuroimaging studies have shown that the right prefrontal cortex and the basal(More)
Alcohol dependence is a serious condition characterized by persistent desires to drink and unsuccessful efforts to control alcohol consumption despite the knowledge of dysfunction through the usage. The study at hand examined the influence of an alcohol exposure on inhibitory processes. Research provides evidence that trying to resist the temptation to(More)
INTRODUCTION Emotion regulation plays an important role in the development and treatment of depression. The present study investigated whether the emotion regulation strategies, expressive suppression (ES) and cognitive reappraisal (CR) change in the course of cognitive behavior therapy (CBT) of depressive inpatients. Furthermore, it also examined whether(More)
In the course of daily living altering environmental conditions or changing internal states often cause us to abandon obsolete planned or initiated actions and force us to update our behavior. The stop-change paradigm, an extension of the very popular stop-signal paradigm, allows the investigation of response inhibition and response re-engagement in a(More)
OBJECTIVE The Beck Depression Inventory (BDI) is widely used for depression screening in various patient populations. However, there are still insufficient data about its sensitivity and specificity in nonpsychiatric patients. Furthermore, some research suggests that somatic BDI items heighten its sum score artificially in physically ill patients. The aim(More)
OBJECTIVE Cognitive functions dependent on the prefrontal cortex, such as the ability to suppress behavior (response inhibition) and initiate a new one (response re-engagement) is important in the activities of daily life. Central serotonin (5-HT) function is thought to be a critical component of these cognitive functions. In recent studies, 5-HT failed to(More)
OBJECTIVE The calibration of item banks provides the basis for computerized adaptive testing that ensures high diagnostic precision and minimizes participants' test burden. The present study aimed at developing a new item bank that allows for assessing depression in persons with mental and persons with somatic diseases. METHOD The sample consisted of 161(More)
