## Abstract

This full day tutorial is an exposition of a rapidly growing new
alternative approach to building computational models of cognition and decision
based on quantum theory. Quantum theory provides a fundamentally different
approach to logic, reasoning, probabilistic inference, and dynamical systems. For
example, quantum logic does not follow the distributive axiom of Boolean logic;
quantum probabilities do not obey the disjunctive axiom of Kolmogorov
probability; quantum reasoning does not obey the principle of monotonic
reasoning. It turns out that humans do not obey these restrictions either, which
is why we consider a quantum approach. This tutorial will provide an exposition
of the basic assumptions of classic versus quantum information processing
theories. These basic assumptions will be examined, side by side, in a parallel
and elementary manner.
