Background: Posttraumatic stress disorder (PTSD) is associated with enhanced noradrenergic activity. Animal and human studies demonstrate that noradrenergic stimulation augments consolidation of fear learning. Retrieval of well-established memories by presenting a learned fear cue triggers reconsolidation processes during which memories may be updated, weakened, or strengthened. We previously reported that noradrenergic blockade in the rat amygdala impairs reconsolidation of fear memories. Here we investigated the effects of noradrenergic enhancement on reconsolidation of learned fear.

Objective: This study investigated the association between mindfulness, other resilience resources, and several measures of health in 124 urban firefighters. Method: Participants completed health measures of posttraumatic stress disorder (PTSD) symptoms, depressive symptoms, physical symptoms, and alcohol problems and measures of resilience resources including mindfulness, optimism, personal mastery, and social support. The Mindful Awareness and Attention Scale (MAAS, Brown & Ryan, 2003) was used to assess mindfulness.

Clinically depressed individuals have consistently been shown to demonstrate a bias for overgeneral autobiographical memory (ABM) disclosure, a strategy used to protect against the access of intense, primary emotions that may accompany specific memories. The present study examined how ABM specificity in client narratives was related to expressed emotional arousal in brief emotion-focused and client-centred psychotherapy for depression.

This article presents data from a longitudinal study of adjustment to policing, specifically examining the role played by exposure to traumatic events prior to entry to the profession. This study aims to explore the impact of a prior traumatic experience on the appraisal of potentially traumatizing events experienced within the policing context. Seventy-eight police constables were followed from point of entry until the completion of 12 months of operational duties.
