Brain, perception, reality: video worksheets, differentiated.

Please ensure you can access the video before you get this resource. By breaking down several optical illusions the film explains how the brain, working on an incomplete set of cues, constructs a complete model of the visible environment — which can often be wrong. The film describes spatial perception, 3 Cartesian dimensions mapped onto the 2-D retina, visual and physiological cues in depth of field perception. The Ames window, the carpentered world. Anamorphism, the Ames room, Hans Holbein’s “The Ambassadors”; The Ames chair. Constellations incl. Orion. The importance of binocular vision and parallax.

Find the film by searching YouTube’s Be Smart channel for “9 Illusions That Explain How Your Brain Constructs Reality”. My link omits a supporter’s message at the end, the film will stop straight after my sheet’s final question if you use my embedded link.

13 questions for the 19-min film (not inc. the omitted message). Differentiated! Both versions look very similar, but “B” version has subtle clues. Questions right up to the end (of my embedded link), no slack time! Excellent subtitles, typed in by a human, not auto-generated nonsense. Answer sheet. Very easy to mark. .doc & .pdf for all files. Link to film on all sheets.
