MENTAL LOGIC AND THE DENIALS OF CONJUNCTIONS AND DISJUNCTIONS
ResumoThe mental models theory predicts that, while conjunctions are easier than disjunctions
for individuals, when denied, conjunctions are harder than disjunctions. Khemlani, Orenes, and
Johnson-Laird proved that this prediction is correct in their work of 2014. In this paper, I analyze
their results in order to check whether or not they really affect the mental logic theory. My conclusion
is that, although Khemlani et al.’s study provides important findings, such findings do not necessarily
lead to questioning or to rejecting the mental logic theory.
