Protocols of people attempting to solve syllogistic problems and explaining how they reached their conclusions were examined. Two main groups of subjects were identified. One group represented the relationship between classes in a spatial manner supplemented by verbal representation. The other group used a primarily verbal representation. A…

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…
