paying attention also involves choosing what to ignore. For an object to come into the spotlight, thousands of others must remain in the shadows. To direct attention is to choose, filter, and select: this is why cognitive scientists speak of selective attention. This form of attention amplifies the signal which is selected, but it also dramatically reduces those that are deemed irrelevant. The technical term for this mechanism is “biased competition”: at any given moment, many sensory inputs compete for our brain’s resources, and attention biases this competition by strengthening the representation of the selected item while squashing the others.
Indeed, there are (in my humble opinion) many phenomena throughout the everyday lives of humans, perhaps throughout all of life in general which are embedded with principles of automatism / automaticity. One of the primary reasons we aren’t talking a whole lot about them is that these things seem invisible to our awareness, or perhaps so blatantly obvious that we don’t ever mention them because we’re convinced they must be plain and simple “common sense”.
