Erik Erikson (1902-1994) used Freud's work as a starting place to develop a theory about human stage development from birth to death. In contrast to Freud's focus on sexuality, Erikson focused on how peoples' sense of identity develops; how people develop or fail to develop abilities and beliefs about themselves which allow them to become productive, satisfied members of society. Because Erikson's theory combines how people develop beliefs psychologically and mentally with how they learn to exist within a larger community of people, it's called a 'psychosocial' theory.
Erikson's stages are, in chronological order in which they unfold: trust versus mistrust; autonomy versus shame and doubt; initiative versus guilt; industry versus inferiority; identity versus identity confusion; intimacy versus isolation; generativity versus stagnation; and integrity versus despair. Each stage is associated with a time of life and a general age span. For each stage, Erikson's theory explains what types of stimulation children need to master that stage and become productive and well-adjusted members of society and explains the types of problems and developmental delays that can result when this stimulation does not occur.
For example, the first psychosocial stage is trust versus mistrust, and it spans from birth to about age one year. During this phase, if children are consistently provided all their basic needs such as food, clean diapers, warmth, and loving affection and soothing from caregivers, they will learn that they can trust other people in their environment to love them and to take care of them, and they will believe the world is good. If infants are neglected and not given these things consistently or if they are taken care of roughly and unpredictably, they will learn to question their caretakers and to believe that others will not always be there to support them when it's needed. Learning to trust others is the first necessary step to learning how to have loving, supportive relationships with others and to have a positive self-image.
The second stage, autonomy versus shame and doubt, spans ages one to three years. When children are autonomous, they feel confident that they can make their own choices and decisions and that they will be positive experiences. Young children become autonomous when caregivers are supportive and give children the safe space to make their own decisions and to experiment with their bodies and problem-solving skills without shaming or ridiculing the child. When children feel shame and doubt, they believe that they are not capable of making valid decisions and not capable of doing everyday tasks. This will begin stunting a positive self-esteem as these small children start seeing themselves as “stupid.”
The third stage, initiative versus guilt, spans ages three to six years. When children develop initiative, they continue to develop their self-concept and gain a desire to try new things and to learn new things while being responsible for their actions to some extent. If caregivers continue to give children a safe space to experiment and appropriate stimuli to learn, the children will continue to find their purpose. However, if caregivers try to create too many strict boundaries around what children can do and to force too much responsibility on kids, children will feel extreme guilt for their inability to complete tasks perfectly.
This is just a taste of Erickson's ideas. Hopefully, these paragraphs will help explain his way of thinking and organizing development. The rest of Erikson's stages will be outlined in detail in future documents in this series as they become age-related.
