    abstract     = {Summary: 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.},
