Summary

This study will examine context sensitivity, composed of two sequential elements: (a) accurate classification of changing affective contextual demands, followed by (b) flexible selection of regulatory strategies that matches changing contextual demands, among complex PTSD vs. Healthy controls.

Detailed description

The study will recruit adults with posttraumatic stress disorder (PTSD) due to a repetitive inter-personal trauma and healthy adult controls which do not meet DSM-5 criteria for PTSD and do not meet the clinical cutoff of Anxiety and Depression screening questionnaires. A compatibility check, filtering, verification of exclusion criteria and informed consent will occur via online self-report questionnaires. Clinical questioners include: Life event Checklist (LEC) - PTSD criteria A Post-trauma Checklist for DSM-5 (PCL) - PTSD symptoms Patient Health Questionnaire (PHQ-9) - Depression Symptoms General Anxiety Disorder Questioner (GAD-7) - Anxiety Symptoms Participants who pass the initial filtering, will be called and provided with an explanation about the study following which they received the online experiment. Modified regulatory selection flexibility paradigm- included 3 blocks: (A) Stimuli Classification- 80 emotional words (equally distributed between high or low intensities) are presented and participants are asked classify each emotional word to high or low intensity. (B) Regulatory Selection- 40 emotional words (out of the 80 presented in block A) are presented and participants are instructed to behaviorally choose between distraction and reappraisal. (B) Regulatory Selection- 40 emotional words (the 40 remaining from block A) are presented, prior to regulatory selection, participants received accurate normed intensity classification of the word and then participants are instructed to behaviorally choose between distraction and reappraisal.
