Degrees, Levels, and Profiles of Contextuality
Ehtibar N. Dzhafarov, Victor H. Cervantes
We introduce a new notion, that of a contextuality profile of a system of random variables. Rather than characterizing a system's contextuality by a single number, its overall degr…
Measures of contextuality in cyclic systems and the negative probabilities measure CNT3
Giulio Camillo, Víctor H. Cervantes
Several principled measures of contextuality have been proposed for general systems of random variables (i.e. inconsistentlly connected systems). The first of such measures was bas…
Hypercyclic systems of measurements and patterns of contextuality
Victor H. Cervantes, Ehtibar N. Dzhafarov
We consider four measures of contextuality, chosen for being based on the fundamental properties of the notion of contextuality, and for being applicable to arbitrary systems of me…
A note on the relation between the Contextual Fraction and CNT2
Víctor H. Cervantes
Contextuality (or lack thereof) is a property of systems of random variables. Among the measures of the degree of contextuality, two have played important roles. One of them, Conte…
On the Quantum-like Contextuality of Ambiguous Phrases
Daphne Wang, Mehrnoosh Sadrzadeh, Samson Abramsky +1
Language is contextual as meanings of words are dependent on their contexts. Contextuality is, concomitantly, a well-defined concept in quantum mechanics where it is considered a m…
Contextuality Analysis of Impossible Figures
Víctor H. Cervantes, Ehtibar N. Dzhafarov
This paper has two purposes. One is to demonstrate contextuality analysis of systems of epistemic random variables. The other is to evaluate the performance of a new, hierarchical…
Epistemic Odds of Contextuality in Cyclic Systems
Ehtibar N. Dzhafarov, Janne V. Kujala, Víctor H. Cervantes
Beginning with the Bell theorem, cyclic systems of dichotomous random variables have been the object of many foundational findings in quantum mechanics. Here, we ask the question:…
Contextuality and Noncontextuality Measures and Generalized Bell Inequalities for Cyclic Systems
Ehtibar N. Dzhafarov, Janne V. Kujala, Víctor H. Cervantes
Cyclic systems of dichotomous random variables have played a prominent role in contextuality research, describing such experimental paradigms as the Klyachko-Can-Binicoglu-Shumovky…
True Contextuality in a Psychophysical Experiment
Victor H. Cervantes, Ehtibar N. Dzhafarov
Recent crowdsourcing experiments have shown that true contextuality of the kind found in quantum mechanics can also be present in human behavior. In these experiments simple human…
True Contextuality Beats Direct Influences in Human Decision Making
Irina Basieva, Víctor H. Cervantes, Ehtibar N. Dzhafarov +1
In quantum physics there are well-known situations when measurements of the same property in different contexts (under different conditions) have the same probability distribution,…
Snow Queen is Evil and Beautiful: Experimental Evidence for Probabilistic Contextuality in Human Choices
Victor H. Cervantes, Ehtibar N. Dzhafarov
We present unambiguous experimental evidence for (quantum-like) probabilistic contextuality in psychology. All previous attempts to find contextuality in a psychological experiment…
Contextuality in Canonical Systems of Random Variables
Ehtibar N. Dzhafarov, Víctor H. Cervantes, Janne V. Kujala
Random variables representing measurements, broadly understood to include any responses to any inputs, form a system in which each of them is uniquely identified by its content (th…
Advanced Analysis of Quantum Contextuality in a Psychophysical Double-Detection Experiment
Víctor H. Cervantes, Ehtibar N. Dzhafarov
The results of behavioral experiments typically exhibit inconsistent connectedness, i.e., they violate the condition known as "no-signaling," "no-disturbance," or "marginal selecti…
Exploration of Contextuality in a Psychophysical Double-Detection Experiment
Victor H. Cervantes, Ehtibar N. Dzhafarov
The Contextuality-by-Default (CbD) theory allows one to separate contextuality from context-dependent errors and violations of selective influences (aka "no-signaling" or "no-distu…
On Contextuality in Behavioral Data
Ehtibar N. Dzhafarov, Janne V. Kujala, Victor H. Cervantes +2
Dzhafarov, Zhang, and Kujala (Phil. Trans. Roy. Soc. A 374, 20150099) reviewed several behavioral data sets imitating the formal design of the quantum-mechanical contextuality expe…
Contextuality-by-Default: A Brief Overview of Ideas, Concepts, and Terminology
Ehtibar N. Dzhafarov, Janne V. Kujala, Victor H. Cervantes
This paper is a brief overview of the concepts involved in measuring the degree of contextuality and detecting contextuality in systems of binary measurements of a finite number of…
