Psy/375 - Life Span Development



Life Span Development
The lives of human beings are in constant change. The changing process begins at conception, and doesn’t end until the person needs to face death. Those changes can be related to individual’s physical appearances and health, mental processes, personality developments, and cognitive processes. Psychologists have defined as life span development the physical and cognitive changes that individuals go through during the course of their lives (Meacham, 2013). 

The concept of life span development is adopted mainly by psychologists who target their studies to human development, and most of them understand that changes are permanently occurring in people’s lives, and are affected by the environment and the context in which they occur. While studying Sigmund Freud’s theory of development, it is possible to note that he focused mainly on the changes that occur in children. For instance, he believed that by the time the child turned five years old, he or she had already completed the personality development, and would carry those traits for the rest of his or her life (Cherry, 2013). The life span perspective of development, on the other hand, seeks to analyze the continuous changes that occur in all individuals, since those changes are not likely to stop at the teenage years. “Lifespan perspective is characterized by an emphasis on plasticity, interdisciplinary research and a multi-contextual view of the nature of development” (Boyd & Bee, 2009). Plasticity means that individuals maintain their ability to change throughout their whole lives, and not only during a certain period of time. It is safe to say that this theory does not support the idea that “you can’t teach new tricks to an old dog”. In fact, it believes that people at all ages can learn, change, acquire new habits and forget about old ones. 

It is impossible to study life span development without focusing some attention at the studies of Sigmund Freud and Erik Erikson regarding the theme. Both psychologists have developed theories concerning stages of development and phases that children must go through in order to complete an appropriate psychological development. 

Freud’s theory is called Theory of Psychosexual Development. He believed that the experiences that children go through during their childhood are crucial for their development, and continue to influence and affect them throughout their lives. Freud explained that a psychosexual energy, also known as the libido, was a “driving force behind behavior” (Cherry, 2013). Each stage is characterized by a conflict, and if individuals completed each stage successfully, that would result in a healthy personality. But if the contrary occurred, and some trauma would occur during a certain stage, the consequences could be permanent, as in the case of fixations. The stages of development described by Freud are the oral, anal, phallic, latent, and genital. The corresponding conflicts, or tasks, that occur during each stage are weaning, toilet training, sexual identity, learning and intercourse (Cherry, 2013).

Erik Erikson’s stages of psychosocial development, unlike Freud’s sole focus on the childhood, explains eight different stages that individuals pass from the time they are born until the late years of their lives. Each stage is characterized by a challenge that if not conquered, may represent problems in the future. During each stage, two conflict forces must be addressed and reconciled. Those stages are trust versus mistrust, autonomy versus shame and doubt, initiative versus guilt, industry versus inferiority, identity versus role confusion, intimacy versus isolation, generativity versus stagnation, and ego integrity versus despair. If the individual is successful at completing each stage, he or she will hopefully advance in life with the virtue mentioned in each stage, like trust, autonomy, identity, etc (Cherry, 2013).

One permanent debate concerning development is the one or nature versus nurture, or which affects the individual the most, the environment or heredity. This discussion compares the generic inheritance a child come to the world with against hoe the environmental factors will change and contribute to that child’s characteristics and personality. Both sides have some really important philosophers and thinkers backing it up. For instance, Descartes and Plato believed in the strength of nature in the development of an individual, and they suggested that some characteristics possessed by humans are inborn, and not affected by the environment. On the other hand, John Locke developed his famous “tabula rasa” theory, with which he explained is idea that children are born as blank slates, or in other words, lacking any knowledge or characteristics, which would all be acquired through life experiences (Cherry, 2013). Having to choose one side of the debate as more influential than the other is a difficult task. Both aspects play the same important role in the development of individuals. For instance, even children who were born into a violent family can turn out calm and friendly, despite his genetic characteristics. And at the same time, a child that grows up in a loving and caring family can end up being a psychopath. Both heredity and the environment influence equally the way individuals go through different stages of development, and hopefully acquire a healthy personality.
