Representation and Its Role in Understanding Problem Solving.
Information about individuals' representations of problems was obtained from studies on reasoning and problem categorization. College students (N=62) participated in a study of the transition from concrete to formal reasoning using the pendulum and chemical yellow tasks. Over a 10-12 week period, 47 students participated in 10 training sessions on various types of problems. Concrete reasoners were more likely than transitional reasoners to represent a conditional statement as equivalent to its converse in sorites and implication problems. Transitional reasoners were more likely than concrete reasoners to mention structural aspects of problems as common characteristics of problems. Results suggest that consideration of individuals' representations of problems can enhance descriptions of structural aspects of reasoning and account for problem-solving behavior on certain logic tasks. College students (N=17) participating in a pilot study on problem categorization sorted 1 of 2 partially identical sets of 55 problems into groups on the basis of similarity and dis- cussed their categorization and their reasons for sorting. Results indicated that initial categorizations of problems rely on relatively superficial, specific, and easily perceivable problem characteristics rather than structural characteristics which are geared more directly toward solution.
