Rorschach Ink-Blots Are Multifractals and a Corresponding Multifractal Strucure is Realized in Humans During Their Perception as Measured by the GSR (Galvanic Skin Response) Neurological and Psycho-Pysiological Signal

We demonstrate that the Rorschach ink-blots are multifractals. Normal subjects submitted to their perception for two minutes have been studied recording their GSR neurological and psychophysiological signal during the observation of the ink blots. It has resulted that also the induced perceptive dynamics in the subject is a multifractal. In the framework of the theory of complexity we elaborate that the intrinsic complexity of the ink-blots induces in the subjects an emotive and cognitive condition of profound inner conflict that may be estimated by the generalized Hurst exponent of the subject as arising from the GSR recording. We expect that the results are important not only in the theory of complexity but also in the clinical study of cases of neurological, psychological and psychiatric interest.
