Inferences from Quantified Expressions.
Revlin, Russell; Kallio, Kenneth
The reversal of subject and predicate terms in quantified, categorical expressions was studied as an operation that is potentially important in issues of representation and comprehension of quantified relations. In two experiments students were asked to evaluate the relation between two quantified expressions. The salience of reversal in the verification of expressions was shown in the first experiment, but quantifier encoding was not flawless. The second experiment examined whether the reversals could be blocked by simple semantic/syntactic manipulation. Blocking was shown to interact meaningfully both with quantifier type and the combined effect of quantifier and conqruity. A three-stage model for the observed latencies was developed, based on the experimental results. Verification profiles showed that students make errors which are attributed to faulty encoding, without discriminating between symmetrical and proper inclusion relations. Alternately, the encoding might be weakly specified. In this way constraints upon subject-predicate order are minimal and low priority, except where the semantic and syntactic aspects of relations show significant asymmetries. (CM)
