Attention bias variability and symptoms of posttraumatic stress disorder.
Cognitive theories implicate information-processing biases in the etiology of anxiety disorders. Results of attention-bias studies in posttraumatic stress disorder (PTSD) have been inconsistent, suggesting biases towards and away from threat. Within-subject variability of attention biases in posttraumatic patients may be a useful marker for attentional control impairment and the development of ...
متن کاملNeural correlates of attention bias in posttraumatic stress disorder.
OBJECTIVE Patients suffering from posttraumatic stress disorder (PTSD) exhibit hyper arousal symptoms and attention problems which were frequently investigated using the P3 event-related potentials (ERPs). Our study aimed at providing more precise knowledge of the functional significance of the P3 alteration seen in PTSD by revealing its spatio-temporal dynamics. METHODS Fifteen PTSD patients...
متن کاملAttention bias to threat in maltreated children: implications for vulnerability to stress-related psychopathology.
OBJECTIVE Previous research in adults implicates attention bias in posttraumatic stress disorder (PTSD). To study attention bias in children, the authors used picture-based versions of the visual-probe attention bias task previously used with adults. They tested the hypothesis that attention bias to threatening facial photographs is associated with maltreatment and PTSD. METHOD A visual-probe...
متن کاملAttentional control as a moderator of the relationship between posttraumatic stress symptoms and attentional threat bias.
Attentional threat bias (ATB) has been suggested as one factor leading to maintenance and exacerbation of posttraumatic stress symptoms (PTSS). In the present study, attentional processes (i.e., facilitated engagement, difficulty disengaging) underlying the association between ATB and PTSS were examined. Additionally, attentional control (AC) was examined as a moderator of this relationship. Pa...
متن کاملHeart Rate Variability and Posttraumatic Stress Disorder.
The psychophysiology of posttraumatic stress disorder (PTSD) points towards autonomic dysregulation—specifically, elevated sympathetic response and attenuated parasympathetic response. In view of this, heart rate variability (HRV) biofeedback has been applied and tested as a treatment for PTSD. Review of existing published research suggests that HRV biofeedback seems promising as a treatment fo...
