On the other hand, how we interpret those sensations is influenced by our available knowledge, our experiences, and our thoughts. This is called top-down processing. Look at the shape in Figure 1 below. Seen alone, your brain engages in bottom-up processing. There are two thick vertical lines and three thin horizontal lines. There is no context to give it a specific meaning, so there is no top-down processing involved. Figure 1.What is this image? Without any context, you must use bottom-up processing. Now, look at the same shape in two different contexts. Surrounded by sequential letters, your brain expects the shape to be a letter and to complete the sequence. In that context, you perceive the lines to form the shape of the letter “B.” Figure 2.With top-down processing, you use context to give meaning to this image. Surrounded by numbers, the same shape now looks like the number “13.” Figure 3.With top-down processing, you use context to gi...
