Abstract The trauma model states that dissociative experiences are determined by recurrent or intense episodes of stress, abuse or neglect, usually occurring in childhood. Paranormal beliefs and experiences have been considered in the literature as important correlates of dissociation and traumatic incidents. On the other hand, studies have identified important contextual effects on measures of trauma, dissociation and belief. When participants were able to infer the goals of the study, they tended to manipulate the results to positively manage the researcher's impression regarding their belief systems, by reducing their scores in psychopathological measures. Another important contextual variable is time. The trauma model predicts a high temporal stability to the reports of traumatic and dissociative experiences, but some of the available evidence is contradictory. There is also controversy about the temporal stability of paranormal beliefs. These evidences establish important challenges to the validity of the results obtained in previous research and for the construct validity of the instruments. In order to enable a detailed evaluation of certain hypotheses, the project was divided into two independent, but related, studies. In the first study, we evaluate the temporal stability of psychometric instruments of trauma, belief and transliminality (a measure of mystical and anomalous experiences), and the role of contextual effects of expectation on the scores of some of the same participants from our previous study (Maraldi, 2014), that will be invited to fulfill the scales once again under specific conditions of persuasion ("neutral", favorable or unfavorable to their beliefs). At the same time, we will evaluate the heart rate variability and electrodermal activity of participants in response to experimental treatments. In the second study, we manage to control contextual effects derived from the joint presentation of scales and presentation order. This is the first Brazilian project that has come to study the role of time, belief and persuasion on psychometric measures of trauma and dissociation. (AU) | |
