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…
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…
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…
Testing Contextuality in Cyclic Psychophysical Systems of High Ranks
Ru Zhang, 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…
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…
Is there contextuality in behavioral and social systems?
Ehtibar Dzhafarov, Ru Zhang, Janne Kujala
Most behavioral and social experiments aimed at revealing contextuality are confined to cyclic systems with binary outcomes. In quantum physics, this broad class of systems include…
Noncontextuality with Marginal Selectivity in Reconstructing Mental Architectures
Ru Zhang, Ehtibar N. Dzhafarov
We present a general theory of series-parallel mental architectures with selectively influenced stochastically non-independent components. A mental architecture is a hypothetical n…
A Note on Quantum States and Observables in Psychological Measurements
Ehtibar N. Dzhafarov
The problem considered is how to map the concepts of Quantum Theory (QT) to elements of a psychological experiment. The QT concepts are "measurement," "state," and "observable". Th…
Quantum Models for Psychological Measurements: An Unsolved Problem
Andrei Khrennikov, Irina Basieva, Ehtibar N. Dzhafarov +1
There has been a strong recent interest in applying quantum mechanics (QM) outside physics, including in cognitive science. We analyze the applicability of QM to two basic properti…
