What are the differences of top-Down and Bottom-up processing.
Bottom-up is based on your sensation, so it’s understanding something through how it looks, tastes, feels, smells, etc. Babies tend to look at the world through bottom-up processing because they don’t have the experience to form perceptions about the world. Once you do that, you use top-down processing. That is where you process something based on your past experiences. So if a baby could speak, they would be pretty garbage at identifying figures in the clouds because they will look at it via bottom-up processing.
