Can quantum probability provide a new direction for cognitive modeling?

EM Pothos, JR Busemeyer - Behavioral and brain sciences, 2013 - cambridge.org
Classical (Bayesian) probability (CP) theory has led to an influential research tradition for
modeling cognitive processes. Cognitive scientists have been trained to work with CP …

Quantum entanglement and the issue of selective influences in psychology: An overview

Context–content systems of random variables: The Contextuality-by-Default theory

EN Dzhafarov, JV Kujala - Journal of Mathematical Psychology, 2016 - Elsevier
This paper provides a systematic yet accessible presentation of the Contextuality-by-Default
theory. The consideration is confined to finite systems of categorical random variables …

Necessary and sufficient conditions for an extended noncontextuality in a broad class of quantum mechanical systems

JV Kujala, EN Dzhafarov, JÅ Larsson - Physical Review Letters, 2015 - APS
The notion of (non) contextuality pertains to sets of properties measured one subset
(context) at a time. We extend this notion to include so-called inconsistently connected …

Selectivity in probabilistic causality: Where psychology runs into quantum physics

EN Dzhafarov, JV Kujala - Journal of Mathematical Psychology, 2012 - Elsevier
Given a set of several inputs into a system (eg, independent variables characterizing stimuli)
and a set of several stochastically non-independent outputs (eg, random variables …

Contextuality is about identity of random variables

EN Dzhafarov, JV Kujala - Physica Scripta, 2014 - iopscience.iop.org
Contextual situations are those in which seemingly'the same'random variable changes its
identity depending on the conditions under which it is recorded. Such a change of identity is …

[PDF][PDF] Quantum structure and human thought

D Aerts, J Broekaert, L Gabora, S Sozzo - Behavioral and Brain …, 2013 - academia.edu
We analyze different aspects of our quantum modeling approach of human concepts, and
more specifically focus on the quantum effects of contextuality, interference, entanglement …

Contextuality in three types of quantum-mechanical systems

EN Dzhafarov, JV Kujala, JÅ Larsson - Foundations of Physics, 2015 - Springer
We present a formal theory of contextuality for a set of random variables grouped into
different subsets (contexts) corresponding to different, mutually incompatible conditions …

All-possible-couplings approach to measuring probabilistic context

EN Dzhafarov, JV Kujala - PLoS One, 2013 - journals.plos.org
From behavioral sciences to biology to quantum mechanics, one encounters situations
where (i) a system outputs several random variables in response to several inputs,(ii) for …

On selective influences, marginal selectivity, and Bell/CHSH inequalities

EN Dzhafarov, JV Kujala - Topics in Cognitive Science, 2014 - Wiley Online Library
The Bell/CHSH inequalities of quantum physics are identical with the inequalities derived in
mathematical psychology for the problem of selective influences in cases involving two …
