BAS Reward Responsiveness: A unique predictor of positive psychological functioning

Abstract Previous research on Reinforcement Sensitivity Theory has well-characterized the Behavioral Inhibition System in terms of its behavioral and emotional manifestations, but the Behavioral Approach System (BAS) is less well-defined, particularly regarding the prominence of reward sensitivity versus impulsivity. Furthermore, few researchers evaluate both systems in one model. We evaluated the relationship between Carver and […]

State rumination enhances elaborative processing of negative material as evidenced by the late positive potential.

Abstract Rumination has been shown to increase negative affect and is highly associated with increased duration of depressive episodes. Previous research has shown that enhanced elaborative processing of negative stimuli is often associated with depression and trait rumination. We hypothesized that engaging in rumination would result in sustained elaborative processing of negative information, as measured […]

Relations between Resilience, Positive and Negative Emotionality, and Symptoms of Anxiety and Depression

Abstract Although research concerning the effects of traumatic and stressful life events on an individual’s mental health has been plentiful in the past several decades, research aimed at understanding the nature of resilience and its role in this process has been less plentiful. The present study examined the relationship between a commonly used measure of […]

Imbalance of default mode and regulatory networks during externally focused processing in depression

Abstract Attentional control difficulties likely underlie rumination, a core cognitive vulnerability in major depressive disorder (MDD). Abnormalities in the default mode, executive and salience networks are implicated in both rumination and attentional control difficulties in MDD. In the current study, individuals with MDD (n =16) and healthy controls (n = 16) completed tasks designed to […]

Brain, body, and cognition: Neural, physiological, and self-report correlates of phobic and normative fear

The phobic fear response appears to resemble an intense form of normal threat responding that can be induced in a nonthreatening situation. However, normative and phobic fear are rarely contrasted directly, thus the degree to which these two types of fear elicit similar neural and bodily responses is not well understood. To examine biological correlates […]

An examination of the representativeness assumption for twin studies of eating pathology and internalizing symptoms.

Little research has investigated whether the twin representativeness assumption (that results from twin research generalize to singletons) holds for eating pathology and internalizing symptoms. This study compared disordered eating, depression, and anxiety among young adult female twins versus singletons. Participants included 292 twins and 997 singletons in three samples. Questionnaires included the Minnesota Eating Behavior […]

The interplay of attention and emotion: Top-down attention modulates amygdala activation in psychopathy

The interplay of attention and emotion: Top-down attention modulates amygdala activation in psychopathy

Psychopathic behavior has long been attributed to a fundamental deficit in fear that arises from impaired amygdala function. Growing evidence demonstrates that fear potentiated startle (FPS) and other psychopathy-related deficits are moderated by focus of attention but, to date, no work on adult psychopathy has examined attentional modulation of the amygdala, or concomitant recruitment of […]
