In past studies, the rubber hand illusion (RHI) was found to be intensified by emotions in healthy participants with greater subclinical manifestation of dissociative symptoms. As body detachment may occur as a consequence of emotional overregulation in arousing situations, we pose the question whether body plasticity, indicated by the RHI intensity, increases in patients with dissociation depending on the degree of emotional arousal. Based on these previous findings and the observation that dissociation is particularly pronounced in children and adolescents, the present study aims to examine differences in the RHI between young patients with high levels of dissociative symptoms and patients or healthy controls with low levels of dissociative symptoms during different emotional conditions. For this purpose, sad (low arousal), fearful (high arousal), and neutral vocalizations are played via headphones throughout six RHI trials (1 synchronous and 1 asynchronous stimulation trial per condition). In each trial, proprioceptive estimations of the real hand position, and a questionnaire on the subjective illusion intensity, a mood rating and a dissociative state questionnaire are completed. Prior to the RHI, a heartbeat detection task is conducted to measure interoceptive abilities, as we expect that interoceptive abilities moderate the effect of the emotional vocalizations on the RHI. According to a power analysis, 75 participants (25 patients with dissociation, 25 patients without dissociation, 25 healthy controls) between 12 and 21 years are required to achieve a power of 80%. By the time of the TEAP conference, data collection should be complete, and results will be presented.
