Developmental Patterns in the Encoding and Combination of Logical Connectives. Technical Report No. 2.
Sternberg, Robert J.
A total of 224 subjects participated in a study to determine how children and adults comprehend logical connectives. Specifically, the study examined the effects of age, content, and practice on the encoding and combination of logical relationships expressed by six types of logical connectives: conjunction, disjunction, conditionality, biconditionality, simple affirmation, and simple negation. The subjects were drawn from grades 2, 4, 6, 8, 11, 12, and college. Half completed a task that required them merely to encode the connectives; the other half were required to combine as well as encode them. The results revealed significant effects of task, age, session, and connective, with comprehension of different connectives developing at different rates. Children as young as second grade encoded the connectives in consistent ways; however, it was not until fourth grade that they showed evidence of consistent combination of connectives. In general, comprehension of the conjunctive connective was the easiest, while comprehension of the conditional and biconditional connectives proved to be the most difficult.
