Although, of all the available theories and research, Erikson is most popular because his work involves identifying the eight different psychosocial stages that occur in an individual's life , focusing on the personal development of one's identity (MacLeod, 2008). He believed that how an individual deals with life's challenges determines whether they will move on to the next stage or stay (Erikson, 2013). His theory considers the influence of external factors, the environment, parents and society as a whole. We begin with the first phase: Trust versus Mistrust, which occurs during childhood and continues through several phases until concluding with the eighth. This is followed by the second phase: Anatomy versus Shame and Doubt (childhood), then the third phase: Initiative versus Guilt (preschool years), the fourth phase: Industry versus Inferiority (early school years), the fifth phase: Identity versus Role Confusion ( adolescence), the sixth stage: Intimacy versus Isolation (young adulthood), the seventh stage: Generitivity versus Stagnation (middle adulthood), before the final stage: Ego Integrity versus Despair (adulthood) (McLeod, 2008). According to Erikson's theory, successful completion of each stage results in a healthier personality and the achievement of some basic strengths that could be used to solve future problems..
