From April 2nd to April 5th, 2024, works related to the implementation of the new version of the Jagiellonian University Repository system will be carried out. It will not be possible to enter new information into the repository during this time. We apologize for any inconvenience.
In this study, we aimed to determine whether reinforced self-affirmation (RSA), consisting of positive feedback about one's memory skills and reflecting on one's achievements, can reduce vulnerability to interrogative suggestibility. We used the Gudjonsson Suggestibility Scale (GSS) to assess two kinds of suggestibility: the tendency to yield to suggestive questions (Yield) and the tendency to give different answers after negative feedback (Shift). The RSA group was administered the RSA before undergoing the standard GSS2 procedure. The control group did not perform the RSA. The results showed that compared with the control group, the RSA group demonstrated significantly lower scores for all measures of interrogative suggestibility. There were no differences in memory skills and confabulation between the groups. Our results suggest that RSA may constitute the basis of an effective method to counteract the effects of misleading questions and negative feedback in the context of interrogation.
