The subject matter of cognitive psychology is thinking: perception (how we see things

Another point about bottom-up: when you have a jumble of letters, its easier to figure out

In our perception, the moon on the horizon appears larger than the zenith moon. This
misperception arises at the stage of the output, when the brain processes the RIS and the
PD to give us a PS. We know that in actuality, the sizes of the moon are in fact
