Mental States Follow Quantum Mechanics During Perception and Cognition of Ambiguous Figures

Processes undergoing quantum mechanics exhibit quantum interference effects. In this case, quantum probabilities result to be different from classical ones because they contain an additional so called quantum interference term. We use ambiguous figures to analyse if during perception-cognition by human subjects we can observe violation of the classical probability field and the presence of quantum interference. The experiments, conducted on a group of 256 subjects, evidence that we indeed have such a quantum effect. Therefore, mental states, during perception and cognition of ambiguous figures, appear to follow quantum mechanics. ∗Correspondence should be addressed to Elio Conte (e-mail: [email protected]) tel. and fax (39) 080 5478414
