When we read (or watch or listen) to a text, our brain builds a schematic of its structure. As we read, our brain literally meets the text halfway.
For example, have you ever stumbled through the beginning of a particularly difficult text (Hawthorne's The Scarlet Letter and Irvine Welsh's Trainspotting both come to mind) only to find that it gets easier the more you try? This is because you're giving your brain time to build a schematic for the text. As you read on, your brain learns to anticipate what comes next, based on what it's processed.
When the text throws our brain a curveball by presenting something we're not expecting, we notice it. These kind of structural "surprises" can put us on edge, provide relief, give us joy, or scare the bejesus out of us. (Think about a scary movie you've seen where a ghost suddenly appears out of nowhere, making you jump out of your seat.)
With this in mind, watch the video below. Ask yourself: What about this video's composition - it's style - tells my brain what to anticipate? How does this manipulate how I feel as I watch?
