We show that quantum mechanical principles, such as superposition and interference, are at the origin of the guppy effect and the overextension and underextension of membership weights of items with respect to the conjunction and disjunction of pairs of concepts.Expand

We show that it is impossible in quantum mechanics to describe two separated physical systems. This is due to the mathematical structure of quantum mechanics. It is possible to give a description of… Expand

It is shown that a lack of knowledge about the measurements of a physical system gives rise to a nonclassical probability calculus for this physical system. It is also shown that the nonclassical… Expand

We analyze the difference between classical mechanics and quantum mechanics. We come to the conclusion that this difference can be found in the nature of the observables that are considered for the… Expand

This article summarizes the history and current status of concepts research and provides a nontechnical summary of work toward an ecological approach to concepts.Expand

We present a general formalism with the aim ofdescribing the situation of an entity, how is, how itreacts to experiments, how we can make statistics withit, and how it ‘changes’ under the influence of the rest of the universe.Expand

We present a numerical mathematical model for the representation of a concept, built with a mathematical formalism originally used in quantum mechanics, and we show that the data of the above mentioned experiment can be reproduced.Expand

A theory for modeling concepts that incorporates how a context influences the typicality of an exemplar and the applicability of a single property of a concept.Expand

We analyze different aspects of our quantum modeling approach and, more specifically, focus on the quantum effects of contextuality, interference, entanglement, and emergence, illustrating how each of them makes its appearance in specific situations of the dynamics of human concepts and their combinations.Expand
