The paper demonstrates the usefulness of this effect logic in quantum cognition

This paper illustrates applications of a new, modern version of quantum logic in quantum cognition. The new logic uses `effects’ as predicates, instead of the more restricted interpretation of predicates as projections – which is used so far in this area. Effect logic involves states and predicates, validity and conditioning, and also state and predicate transformation via channels. The main aim of this paper is to demonstrate the usefulness of this effect logic in quantum cognition, via many high-level reformulations of standard examples. The usefulness of the logic is greatly increased by its implementation in the programming language Python.
