Repetitive thought may have adaptive and functional consequences, depending on, among other things, the interpretation of the content: analytical or abstract (general and decontextualized) and experiential or concrete (specific, contextual and incidental). Studies experimentally manipulating repetitive thought have shown both the constructive consequences of the experiential mode and the dysfunctional consequences of the analytical mode. The aim of the current study is to observe the effect of analytical and experiential rumination of negative self-defining memories on schizotypic symptoms. A sample of 111 university students were randomly assigned to one of the two experimental conditions of induced rumination, "analytical" or "experimental." The participants completed a series of questionnaires (anomalous perception of reality, preoccupation and depression) and a negative self-defining memory was obtained to be used as the content of the induced rumination. Following the rumination induction, participants in the experiential condition significantly decreased their scores on anomalous perception of reality compared with those in the analytical condition. We also observed that post-induction scores on self-reported sadness significantly increased in both experimental conditions while scores on self-reported happiness decreased. Our results show that the concrete/experiential rumination, focused here on negative self-defining memories, have positive consequences on schizotypic symptoms, such as decreased anomalous perception of reality.
