A theory of deductive reasoning is presented for inferences that depend on multiply quantified premises. It is argued that reasoners construct mental models based on their knowledge of the meaning of the quantifiers. Three experiments, with 54 university students and adults, corroborated the theory.

Tested with adolescents and adults two predictions from Markovits and Barrouillet's developmental model of conditional reasoning related to the effects of the association between antecedent and consequent terms and the formulation of the minor premise on uncertainty responses. Found results consistent with hypotheses and indicating importance of…

Argues that the syntactic and mental model accounts of the suppression effect in deductive reasoning are inadequate. Proposes a relative salience model. Describes a test of predictions from this model in a suppression model, which obtained evidence of convergent validity for the salience construct. Results could not be reconciled with either the…
