Reports survey results on proof conceptions. Presents an overview of responses at the end of year 8 (age 13 years) and year 9 (age 14 years). Distinguishes three strategies--empirical, focused-empirical, and focused-deductive--that represent shifts in attention from an inductive to a deductive approach. Indicates some progress from year 8 to year…

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.

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…

Three experiments using university students explored what constitutes an event and what determines its boundaries. Results supported the hypothesis that sequences of stimuli repeating in different contexts are cut out to become cognitive entities ("things" with a beginning and an end) in their own right. Results suggest that the…

However, it has also been pointed out that there is nothing inherently Chinese…
