Answer:
During their childhood, kids learn about the world that surrounds them when going through 3 different phases regarding their body parts, and taking contact with their family and school; when puberty strikes, the learning shifts towards the teen's peer group and their chosen role models to create new patterns in behaviour and find themselves (adolescence). Once the individual enters adulthood and establish his/her personality, can form strong and intimate relationships with friends and romantic partners (transitional adulthood). When reaching the middle years, the person needs to contribute to society in some way to feel productive, like raising children or helping his/her community. Finally, during the older years, humans tend to reflect on their lives and accomplishments to develop a sense of either integrity or despair.
