I'm sure that you are familiar with phrases such as 'he's so anal about things' being used to describe someone who is a little uptight. Or maybe, you've heard a smoker describing his or her habit as being an 'oral fixation'. These are two pretty common ways of describing human behavior that have both worked their way into everyday conversational language. You may even used these phrases without realizing they are actually tied to a highly influential psychodynamic theory of human personality development.

Famed psychodynamic theorist and psychoanalyst Sigmund Freud believed that human personality develops via a process he called psychosexual development. According to Freud, sex was the driving force behind our thought processes and also the primary influence behind how we develop our personalities as we grow and develop. Freud's stage theory of personality development proposes that each specific stage focuses on a different area of the body which experiences a heightened sense of sexual pleasure at various periods of time.

Starting from birth and working through adulthood, Freud believed that we pass through six distinct stages; the oral stage (birth to 18 months), the anal stage (18 months to 36 months), the phallic stage (three to six years), a latency period (six years to puberty onset), followed by the genital stage (adolescence into adulthood).

Let's take a closer look at the first stage, which Freud referred to as the oral stage.


The oral stage of personality development begins at birth and lasts up until around 18 months of age. If you have ever been around babies you know that their mouth is the focus of a lot of attention. From eating, to fingers, to toys, babies are seemingly in almost constant contact with their mouths. Freud's observations led him to believe that this is because the baby is experiencing a high level of pleasure from engaging in activities centered on the mouth. Since it feels good to the baby to put things in her mouth she does it as often as possible. Not only does it feel good, but Freud believed that engaging in activities centered on the mouth is a source of stress relief and comfort for the baby as well.

You might be thinking to yourself that there are several biological reasons for babies engaging in activities centered around their mouth, and you would be correct. But Freud believed that these activities went beyond just biology. He believed that the psychosexual stages had a great impact on how our personality develops, which in turn impacts who we become as adults and how we choose to think and behave.
