Theories Of Natural Selection And Psychoanalytic...

Charles Darwin and Sigmund Freud are both widely known respectively for their natural selection and psychoanalytic personality theories. Charles Darwin helped further the field of evolutionary psychology while Sigmund Freud helped discover the unconscious which is still debated to this day about whether it is real. Darwin’s natural selection theory talks about how organisms adapt to survive and the two types of sexual selection which is intersexual and intrasexual selection. Freud’s theory of psychoanalytic personality talks about how the id, ego, and superego affects our behavior and talks about how our unconscious is a very important aspect in our lives.

These things listed above regarding natural selection shows that organisms adapt to survive. Darwin also proposed that there are two types of sexual selection which is intrasexual competition and intersexual selection. Intrasexual competition is when two of the same species that is of the same sex go against each other and the winner has a higher selection of mates. Usually the winner has better qualities that help increase survivability. They pass their genes on to future generations which helps increase survivability over the whole species eventually. Intersexual selection is when mates are chosen because of the certain qualities that an organism is looking for. Species with the characteristics desired tend to mate more which means most of those genes carry over to future generations. Genes tend to slowly disappear from the species if they don t mate as often. The psychoanalytic personality theory is composed of three structures of the mind: the id, ego, and superego. According to Freud, we are born with the id and is where all our urges and drives occur. We just want whatever we want and want it right then and there. This is called the pleasure principle.Show MoreRelatedStructuralism And The Development Of Psychology874 Words   |  4 Pagesprocess b) Gestalt- Max Wertheimer sought to explain perceptions in terms of results rather than by analyzing their constituents c)Psychoanalytic/psychodynamic-Sigmund Freud revolutionized psychology with his theory of psychoanalytic, he believed he discovered the unconscious mind.
