Kruschke, J. K. (1996). An Interactive Classroom Demonstration for Explaining Propositional and Analogue Representation. Teaching of Psychology, 23, 162-165.
ABSTRACT: In a cognitive psychology demonstration, students see a rat's eye view of a maze, projected from a computer, and vocally vote for moves through the maze. The class takes false paths in the first run, but avoids them in the second. The learning can be explained in terms of analogue imagery or in terms of propositions and rules for modifying them. The demonstration achieves three goals: It actively engages students, it effectively explains the concepts, and it provides a memorable referent for explaining other topics such as algorithms versus heuristics, production systems, and phrase-structure grammar.
