We present a cognitive psychology experiment where participants were asked to select pairs of spatial directions that they considered to be the best example of Two different wind directions. Data are shown to violate the CHSH version of Bell’s inequality with the same magnitude as in typical Bell-test experiments with entangled spins. Wind directions thus appear to be conceptual entities connected through meaning, in human cognition, in a similar way as spins appear to be entangled in… 
Spin and Wind Directions II: A Bell State Quantum Model
TLDR
A cognitive psychology experiment where participants were asked to select pairs of directions that they considered to be the best example of Two Different Wind Directions is analyzed, and it is shown that the data violate the CHSH version of Bell’s inequality, with same magnitude as in typical Bell-test experiments in physics.
A Planck Radiation and Quantization Scheme for Human Cognition and Language
TLDR
It is shown that the lack of independence of the Bose-Einstein statistics compared to the Maxwell-Boltzmann statistics can be explained by the presence of a ‘meaning dynamics’, which causes words to be attracted to the same words.
Entanglement in Cognition violating Bell Inequalities Beyond Cirel'son's Bound
TLDR
It is observed that a quantum model in Hilbert space can be elaborated in these Bell-type situations even when the CHSH violation exceeds the known ‘Cirel’son bound’, in contrast to a widespread belief.
Quantum entanglement in physical and cognitive systems: A conceptual analysis and a general representation
TLDR
The phenomenon of entanglement in bipartite systems is provided, as it manifests in micro and macro physical systems, as well as in human cognitive processes, by observing that when genuine coincidence measurements are considered, the violation of the ‘marginal laws’ is to be expected.
Quantum-Theoretic Modeling in Computer Science
TLDR
A quantum-theoretic model is worked out in complex Hilbert space of a recently performed test on co-occurrencies of two concepts and their combination in retrieval processes on specific corpuses of documents, indicating the presence of entanglement between the combined concepts.
On the Foundations of the Brussels Operational-Realistic Approach to Cognition
TLDR
The theoretical foundations of the quantum approach to cognition that is developed in Brussels are provided, and the recently derived `extended Bloch representation' of quantum theory precisely provides such extended formalism, while remaining within the same unitary interpretative framework.
An overview of the quantum cognition research programme
TLDR
This review provides a representative overview of quantum cognitive models applied to several areas of psychology, with coverage in perception, memory, similarity, conceptual processes, causal inference, constructive influences in judgment, decision order effects, conjunction/ disjunction fallacies in decision making, and other judgment phenomena.
Quantum Cognition.
TLDR
This work motivates the use of quantum theory in cognition and its key characteristics, and casts a critical eye on quantum models and some of their shortcomings and issues regarding their further development.
Quantum–Inspired Measure of Behavioral Semantics
TLDR
A measure to quantify strength of semantic relation between two pairs of binary alternatives in cognition of a subject group is proposed and demonstrated by quantifying culture-specific semantic relations between the archetypal living creatures and their qualities.
On the Conceptuality Interpretation of Quantum and Relativity Theories
How can we explain the strange behavior of quantum and relativistic entities? Why do they behave in ways that defy our intuition about how physical entities should behave, considering our ordinary

Quantum Entanglement in Concept Combinations
TLDR
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 Models for Psychological Measurements: An Unsolved Problem
TLDR
The applicability of QT to two basic properties in opinion polling, response replicability and question order effect, are analyzed and stand out as important unresolved problems for the application ofQT to cognition.

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
Loophole-free Bell inequality violation using electron spins separated by 1.3 kilometres
TLDR
The data imply statistically significant rejection of the local-realist null hypothesis and could be used for testing less-conventional theories, and for implementing device-independent quantum-secure communication and randomness certification.

Quantum Structure in Cognition: Why and How Concepts Are Entangled
TLDR
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.
Quantum Particles as Conceptual Entities: A Possible Explanatory Framework for Quantum Theory
We put forward a possible new interpretation and explanatory framework for quantum theory. The basic hypothesis underlying this new framework is that quantum particles are conceptual entities. More
Quantum Models of Cognition and Decision
TLDR
The foundations for modelling probabilistic-dynamic systems using two aspects of quantum theory, 'contextuality' and 'quantum entanglement', are introduced, which allow cognitive phenomena to be modeled in non-reductionist ways.
