Wonder how you might use this to alter teaching? "In Lupyan's study, participants sometimes heard the name of the static object - like the word 'kangaroo' or 'pumpkin' - played into their ears. And on these trials, the previously invisible object would pop into their conscious visual perception. If they heard a different word, though, they would not see the hidden object. "So it's not that they are hallucinating or imagining a dog being there," Lupyan says. "If they hear the label, they become more sensitive to inputs that match that label." "

"Confucius famously urged followers to heed the Golden Rule: do to others what you would have them do to you. However, he was also famous for another concept: jen. According to Confucius, a person of jen "brings the good things of others to completion and does not bring the bad things of others to completion." In other words, jen represents our ability to make the world a better place…but also a worse one. In this lesson we'll explore the concept of the jen ratio - the ratio of positive to negative observations in our daily lives - and discuss how it influences the way we experience the world. From violent video games to inspiring hip-hop lyrics, how does the Confucian concept of jen shape our lives?" This seems like a very engaging introduction to ratios. This is a paid resource, but the media for this lesson is free and available to all.
