This workshop provides participants an advanced overview of the neurobiological, cognitive, emotional, and behavioral functioning of those exposed to traumatic incidents (e.g., abuse, disaster, war). This presentation will be divided into two parts. First, a discussion on single incident traumatic exposure (acute trauma), its definition, effects on cognitive and somatic functioning, and behavioral presentation. The second part will discuss the effects of multiple incidents of traumatic exposure (complex trauma), and will include an overview of the psychosomatic mechanisms that produce confusing and often difficult to treat symptoms (e.g., extreme aggression, blackouts, self-harm, hallucinations, and dissociation). Discussions of how to effectively work with traumatized populations will be woven throughout the presentation. This workshop is open to students.
