Theories and Theorists on Lifespan Development

Trust gives babies new experience; fear of unknown is considered part of life (1993). The second stage is an anal stage; this is 1 to 2 years old. During this time, Freud believes that the main focus of libido is to suppress bladder and bowel movements. The stage of conflict is toilet training, as babies must learn to control their physical needs. In development, this will help bring independence and sense of accomplishment.

Theorist Erik Erikson also proposed a developmental theory, but his theory covers human growth through human life. Ericsson believes that emphasis is placed on overcoming competition at each stage of development. For example, the main conflict in puberty involves establishing a sense of personal identity. Dealing with the success or failure of competition at each stage will affect the overall operation. For example, adolescents may confuse us if we can not form an identity.

When analyzing the different stages of an individual's life, many psychologists have come up with many theories to study certain aspects of life. Several theorists are Jean Piaget who advocates cognitive development theory. In the 20th century he was one of the most influential researchers in the field of developmental psychology and assumed that individuals made progress through four stages of psychology and inference development. There is also the theory of psychology proposed by psychology father Sigmund Freud. He believes that individuals experienced five levels of sexual development. Freud believes that if all the stages of sexual development are properly handled, that person will develop into a mature and adaptable person.
