CONDITIONALS AND DISJUNCTIONS IN MENTAL-LOGIC THEORY: A RESPONSE TO LIU AND CHOU (2012) AND TO LÓPEZ ASTORGA (2013)

Liu and Chou (2012) presented a two-step theory to describe reasoning both on the four traditional conditional syllogisms and on four parallel syllogisms that replace the conditional with a disjunction. This article proposes that although Liu and Chou show that the words if and or play an important...
