Concepts and Their Dynamics: A Quantum-Theoretic Modeling of Human Thought
The relevance of complex numbers, the appearance of entanglement, and the role of Fock space in explaining contextual emergence, all as unique features of the quantum modeling are explicitly revealed in this article by analyzing human concepts and their dynamics.
Quantum Structure in Cognition: Why and How Concepts Are Entangled
It is shown that the intrinsic and unavoidable character of entanglement can be explained in terms of the weights of the exemplars of the combined concept with respect to the weightsof the exemplar of the component concepts.

Identifying Quantum Structures in the Ellsberg Paradox
Empirical evidence has confirmed that quantum effects occur frequently also outside the microscopic domain, while quantum structures satisfactorily model various situations in several areas of…
A Quantum Model for the Ellsberg and Machina Paradoxes
A quantum model in Hilbert space is elaborate describing the Ellsberg situation and also the Machina situation, and it is shown that this model can model the specific aspect of the Machina situations that is unable to be modeled within the existing generalizations of expected utility.

It is pointed out that also quantum structure different from quantum probability abundantly plays a role in human cognition, and states, observables, complex numbers, and Fock space as specific mathematical structures are mentioned.
Quantum Entanglement in Concept Combinations
This paper analyzes the data collected in an experiment on a specific conceptual combination, showing that Bell’s inequalities are violated in the experiment, and presents a new refined entanglement scheme to model these data within standard quantum theory rules, where ’entangled measurements and entangled evolutions’ occur, in addition to the expected ‘entangled states’.
Quantum Structure in Cognition: Fundamentals and Applications
A contextual framework for both concept representation and decision making is constructed, together with quantum models that are in strong alignment with experimental data, and the presence of a quantum structure in cognition shows that quantum mechanics supplies a structural model for human and artificial thought processes.

This paper isolates a new, very stable and systematic pattern of violation of classicality that occurs in concept combinations and shows that this effect can be faithfully modelled in a two-sector Fock space structure, and can be exactly explained by assuming that human thought is the superposition of two processes.
Spin and Wind Directions I: Identifying Entanglement in Nature and Cognition
Wind directions seem to be conceptual entities connected through meaning, in human cognition, in a similar way as spins appear to be entangled in experiments conducted in physics laboratories.
