A nice primer into the connection between psychology and biology. Imagine sitting on the sandy beaches of the Florida Keys. You feel a swift breeze rush over you as you gaze lazily at the descending sun, shaded by its faint glow by a palm tree. The sunset gives you a feeling of peacefulness and pleasure. Psychology determines what people perceive to feel and behave, but underlying it all - ultimately determining the way we act, feel and behave is biology.
Biology is the science of living things.
It is a rather broad discipline encompassing everything from how plants make energy and food from sunlight and water to how the human brain works. Consequently, it is important for psychologists to establish a bridge between psychology and biology. This lesson won't cover everything in biology, but it will give you a focused introduction into how biology affects behavior. When studying psychology there are three important approaches of biology to keep in mind. One approach in biology is the causation of behavior.
