Plausibility Versus Logical Necessity in Children's Verbal Reasoning.
Hidi, Suzanne; Bereiter, Carl
Studies of children's verbal reasoning that are focused on the valid principles of conditional reasoning indicate that young children (1) draw inferences from logically unconnected semantically related statements; (2) arrive at conclusions on the basis of no presented evidence; (3) do not differentiate between definite and indefinite propositions; (4) never indicate uncertainty; and (5) do not comprehend conditionality. To investigate the invalid principles of conditional reasoning, further experiments were conducted. Conditional rules were presented through concrete instances from which children had to infer the rules, as opposed to the usual procedure of giving the rules verbally in the form of conditional statements. It was found that virtually all of the incorrect responses of third, fifth and sixth grade students were consistent with a biconditional interpretation of the rules (i.e., If x, then y and, if y, then x.). These results seem to point to a switch in children's reasoning patterns. Reasoning to logically correct conclusions with valid principles requires staying within given information. Rejecting an invalid inference requires going outside the given information. Research has shown that, when performing tasks requiring reasoning with valid principles, young children err by going outside of given information. However, in failing to reject invalid inferences, children err by staying within the given information. (Author/RH)
