Teaching Students Some Cognitive Science to Evaluate Weird Perceptual Experiences: Some Advantages of the "We See What Our Evolutionary Ancestors Needed to See" Approach

How can we use what cognitive science has taught us about perception to improve the critical thinking skills of our students? What, for instance, does it tell us about subjects who think they've seen Bigfoot, ghosts, and other "weird things"? I explore two approaches for giving students some empirically based tools for examining cases like these. The first, which I call the "we see what we want to see"approach, focuses the idea that beliefs and desires can shape our visual experiences. This approach, however, encourages students to view subjects who report weird experiences as being cognitively irresponsible and worthy of derision. The second approach, which I call the "we see what our evolutionary ancestors needed to see"approach, asserts these experiences are the result of evolutionarily designed perceptual mechanisms that specialize in representing human-like qualities. Fortunately, the second approach does not create the same problematic attitude in students as the first.
