Probability amplitude in quantum like games

Examples of games between two partners with mixed strategies, calculated by the use of the probability amplitude are given. The first game is described by the quantum formalism of spin one half system for which two noncommuting observables are measured. The second game corresponds to the spin one case. Quantum logical orthocomplemented nondistributive lattices for these two games are presented. Interference terms for the probability amplitudes are analyzed by using so called contextual approach to probability (in the von Mises frequency approach). We underline that our games are not based on using of some microscopic systems. The whole scenario is macroscopic.Comment: Quantum-like model

Cardiovascular autonomic control during respiratory paced hypnosis

The capability of hypnosis to act on the Autonomic Nervous System under a controlled breath condition (12 breaths/min) was assessed in 11 healthy volunteers. Subjects were split into high and low susceptibility to hypnosis groups, using the Stanford hypnotic susceptibility scale form {C} (SHSS). Autoregressive power spectrum analysis of RR interval and SAP variabilities provided the markers of cardiac sympatho-vagal interaction (LF/HF) and vascular sympathetic vasomotor control ({LF}-{SAP}). Under controlled respiration, no significant changes in LF/HF ratio were observed between the two groups. Hypnosis induced a significant increase of {LF}-{SAP} in high susceptible subjects. These preliminary results highlight how the state of hypnotic trance acts directly on the cardiovascular autonomic profile by increasing the sympathetic vascular activity only in high susceptible subjects. These effects become evident when the role of potential changes in respiration rate are excluded by the controlled breathing condition
