A PICTORIAL DOT-PROBE STUDY Abstract book page 103 Introduction. Post-Traumatic Stress Disorder (PTSD) is a psychiatric condition that develops after the exposure of a traumatic event (APA, 2013). It is mainly characterised by symptoms of intrusion, avoidance, alteration of arousal and reactivity. Models have tried to identify cognitive factors that could explain the exacerbation and maintenance of such symptoms (Ehlers & Clark, 2000). Literature has highlighted the involvement of memory biases and attentional biases toward threatening information (Bardeen & al., 2016). This study seeks to explore (1) the time course of attentional biases, (2) memory biases toward threat, (3) the differential processing of traumatic and negative information. Method. To this aim, 20 participants (18 to 50 years old) will be recruited and assigned to two groups according their scores at the PTSD Symptom Scale Interview (PSS-I). Our study focuses on trauma related to aggression, due to its prevalence in collaborative hospitals. Low cognitive functioning measured with Mini Mental State Evaluation (MMSE) has been used as exclusion criteria. To provide a temporal examination of attentional allocation, an original dot-probe task with two different presentation times (150 and 500 ms) was created. Pictorial stimuli were used and mainly selected from International Affective Picture System (IAPS). For a better understanding of memory biases in PTSD, participants performed a recognition task using the remember/know paradigm. In those tasks, three different kinds of pictures were displayed: positive, trauma-related ones (street aggressions) and pictures with negative valence (spiders, plane crashes). Results and discussion. First results will be discussed with regard to recent literature.
