Four experiments with college undergraduates examine interactions between linearly separable and nonlinearly separable abstract category structures, different knowledge types, and instructions on classification learning tasks. Implications for independent cue models and interactive cue models are discussed. (LMO)

Three experiments using college students examine the processes involved in deductive reasoning. Effects of training in classroom and laboratory situations confirmed the authors' hypothesis that people use pragmatic reasoning schemas rather than syntactics rules of logic for problem solving. Training materials used in experiments 1 and 3 are…
