Learning Without Thinking
This site is inspired by the perceptual learning module developed by Philip Kellmann, in which the student taking flight lessons is shown a display of six cockpit dials and seven choices for the status of the aircraft.
As Benedict Carey writes in his book How We Learn:
The modules are intended to sharpen snap judgments—perceptual skills—so that you "know" what you’re looking at without having to explain why, at least not right away.
Perceptual Learning Module
Each module on this site presents the learner with a series of pictures and a number of choices depending on the test. When a choice is selected, visual feedback on right/wrong answer is provided before moving on to the next picture.
