In Psychopathology of Everyday Life, Freud refers to minor errors in everyday living such as slips of the tongue, forgetting things, and small accidents., The concept of the unconscious, which Freud regarded as already well known amongst poets, was important to his theories and ideas; he also believed that it was his responsibility to ensure that it received scientific recognition in the field of psychology. [163], One of Freud’s most important concepts was repression, the unconscious process of blocking out distressing thoughts or memories. He suggested that traumatic or anxiety-provoking experiences are often repressed into the unconscious, leading individuals to forget or deny painful experiences., Freud proposed that our personality consists of three interconnected systems that often compete for control over our thoughts and actions. Understanding these components helps explain the internal conflicts we all experience., One of Freud’s more famous theories was that of psychosexual development. Fundamentally, Freud postulated that as children we move through a series of stages centred on erogenous zones., Freud proposed three interacting systems present in our minds. These systems are the id, ego, and the superego. The ego or self makes a balance between the aggressive and self-satisfying drives of the id using the regulating power of the superego..
