We show that it is the existence of EPR-like correlation states for the quantum mechanical entity under consideration that make it nonequivalent to the classical situation. Specifically, the presence of potentiality in these correlation states gives rise to the quantum deviation from the classical logical `or'. We show how this arises not only in the microworld, but also in macroscopic situations where EPR-like correlation states are present. We investigate how application of this analysis to concepts could alleviate some well known problems in cognitive science. date: 2000-10 date_type: published publication: Foundations of Physics volume: 30 number: 9 publisher: Plenum/Kluwer pagerange: 1473-1480 refereed: TRUE referencetext: Aerts, D., Aerts, S., Broekaert, J. and Gabora, L., 2000, ``The violation of Bell inequalities in the macroworld", Foundations of Physics, vol. 30 (9): 1387-1414.
