The mental-logic theory's studies for conditional reasoning did not adress whether children make judgments that are consistent with the mental-logic procedural semantics for if. There were two experiments with six to 11 year old children and college students from Brazil and United States of America who were presented to syllogistic problems in different forms. The results show that school children, as well as adults, make judgments that were consistent with the mental-logic procedural semantics for if. Thus, there are reasons to think that there is a logic for condicionals that centers on supposition that is available early in the language and reasoning of children.
