In this essay, we will provide a brief summary of what psychology is and introduce the reader to the main biological foundations of psychology that are related to behavior, as well as the main schools of thought in psychology.

He explains this fact by stating that "all psychological processes occur through the interaction of cells of the nervous system and that all human action occurs in the context of cultural beliefs and values ​​that give it meaning." (Kowalski & Weston, 2009, p. 3). The main biological basis of psychology is related to biopsychology.

Sigmund Freud, the three elements of the id, ego and superego, when implemented together, explain human behavior, even in its most complex form. Psychology plays many roles in the broader field of science, but I will always believe that psychology's most profound role is to enable humans to have a better understanding of themselves and their world. Psychology delves into the deepest levels of the mind and intrigues us with the different theories and observations of our mental and physical abilities. Although there are many schools of thought, each school of thought opens our minds to new theories and concepts that stretch our brains. unlimited limits! Works Cited Kowalski, R. & Westen, D.
