How Visually Intelligent Are You? Take Amy Herman’s Perception Test

Amy Herman, Sept 14, 2016
Commentary by Stephen Downes

I don't usually link to Big Think because the articles are generally plugs for books, and the books (of course) are not open access and so I can't read them (because I have nowhere near the budget it would take). The same is the case with this post. But I'm linking to it for the video, and despite Amy Herman's third-grade level speaking style, it makes an important point: when you are looking at something - an artwork, say, or a medical diagnosis - what is not there can be as important as what is there. She calls this the 'pertinent negative'. She is by no means the first to make this observation - it dates back thousands of years - but her illustration is compelling and makes its importance clear.
