Options for testing temporal Bell inequalities for mental systems

Abstract

It is shown how the concept of Bell inequalities may be used to decide whether "superposition" states exist in mental systems. For this purpose a generalized form of temporal Bell inequalities, originally developed for two-state systems, is derived for systems with any finite number of states. We propose options for testing violations of these inequalities in psychological experiments and discuss the important role of "non-invasive" measurements. Classical models can violate temporal Bell inequalitites, but observations are invasive. © 2011 Springer-Verlag.
