"This demonstration is much like a good magic trick," Simons continued. "A magician can lead the audience to think he's going to make the ball disappear with one method, and while people watch for that technique, he uses a different one. In both cases, the effect capitalizes on what people expect to see, demonstrating that we often miss what we don't expect."
Our brains are built to manage the flow of information this way. However, research is finding there are ways to broaden our attention 'bank account' through relaxation practices. I would argue that practising tuning our sensory and movement skills, exploring new and unknown rhythms, may also help broaden our capacities for awareness.
Understanding that we see only a fraction of the world around us has profound implications. It reminds us of the subjective nature of reality and highlights the unique way each person interprets their surroundings. Understanding this, we can always try to grow our sensory awareness, perhaps emphasizing empathy and a sense of imagination, physically experiencing new things, taking deep breaths, and on occasion remembering that "not everything is always as it seems." It never hurt to ask, "What other rhythms might be possible to perceive?"
