Systems theory has long been used in psychology, biology, and sociology. This paper applies newer methods of control systems modeling for assessing system stability in health and disease. Control systems can be characterized as open or closed systems with feedback loops. Feedback produces oscillatory activity, and the complexity of naturally occurring(More)
Individuals with major depressive disorder (MDD) often ruminate about past experiences, especially those with negative content. These repetitive thoughts may interfere with cognitive processes related to attention and conflict monitoring. However, the temporal nature of these processes as reflected in event-related potentials (ERPs) has not been(More)
The present pilot study investigated the implementation feasibility, and efficacy for reducing alcohol and drug craving, of a brief, 3-session heart rate variability biofeedback (HRV BFB) intervention added to a traditional 28-day substance abuse disorder inpatient treatment program. Forty-eight young adult men received either treatment as usual (TAU) plus(More)
Alcohol cue reactivity, operationalized as a classically conditioned response to an alcohol related stimulus, can be assessed by changes in physiological functions such as heart rate variability (HRV), which reflect real time regulation of emotional and cognitive processes. Although ample evidence links drinking histories to cue reactivity, it is unclear(More)
BACKGROUND The detrimental effects of chronic heavy alcohol use on the cardiovascular system are well established and broadly appreciated. Integrated cardiovascular response to an acute dose of alcohol has been less studied. This study examined the early effects of an acute dose of alcohol on the cardiovascular system, with particular emphasis on system(More)
Parental alcohol use disorders (AUDs) have been conceptualized as a chronic stressor that can lead to deleterious long-term outcomes in children of individuals with AUDs. Yet, while many individuals are detrimentally affected by their parents' problematic alcohol use, and go on to manifest psychological problems, others do not. How individuals cope with the(More)
This investigation sought to validate a stimulus set previously adapted by expert consensus from the International Affective Picture System to be unpleasant and evocative to individuals with borderline personality disorder (BPD). This set was rated as significantly more arousing by 22 individuals diagnosed with BPD compared to 22 healthy controls, though(More)
