8-Stage Lifespan Development
Stage 1: 0-3 years old
I think that the main psychological challenge during this stage of development is the understanding of learning so many new things. The behaviors that someone this age will go through as well as the mental processes pose quite a challenge for someone from a young age.
Stage 2: 4-6 years old
The main psychological challenge for this age is the behavioral aspect of life. At this age I think that many people are learning to act how their parents tell them to act. Also, kids go through the phase of whether they should listen to their parents or act the way they want to act.
Stage 3: 7-12 years old
The main psychological challenge of this age group is the external development of behavior. I think at this age people are beginning to understand how their behaviors and what they say affect others around them.
Stage 4: 13-22 years old
At this stage in life, I think the biggest psychological challenge is stress. Most people around this age are in middle school, high school, or college, and they are faced with new mental challenges that they learn to figure out on their own which can cause a lot of stress. Also, around this age range is when people really judge themselves for how they look, and this can lead to things like anorexia or other eating disorders.
Stage 5: 22-28 years old
In this age group, I think independence in terms of behavioral development emerges on a different level. Around this age, you graduate college, move out, find your own place and start your own life. There is no more relying on other people to help you out anymore, and the responsibility of yourself really comes to light.
Stage 6: 29-40 years old
I think at this age range the biggest psychological challenge is planning ahead. This is the age range where people work a lot and start to plan their future years ahead, possibly even to retirement. This places a lot of stress on the brain as well as the person as a whole.
Stage 7: 41-64 years old
This age range’s biggest psychological challenge is development of new skills. Many people around this age do not possess the capability or the correct mindset to make time to learn something new. This could possibly prevent true happiness or joy from occurring.
Stage 8: 65+ years old
I think the biggest psychological challenge for this age group is keeping everything in order. Around this age and onward dementia may begin to kick in which could lead to episodes of mania or maybe forgetting something or someone that was very important to you.

I think that you have some great ideas, and I would like to compare them to Erikson’s model. I found a website that compiled his eight steps, since they were spread out through the textbook. Your first stage that emphasizes learning is similar to Erikson’s Autonomy vs. Shame. They have similar age ranges and they focus on exploring the world around them. Your second stage that learns behavior is similar to Initiative vs. Guilt. Here, children are learning how to act in different situations. Your third stage composed of external behavior is like Industry vs. Inferiority because the children are comparing themselves to others and establishing their personality. The teenage stage for both models is similar because teenagers are deciding who they truly are and what they want to do with their life. Your stages with the age ranges of 22-28 and 29-40 are more modern takes of Erikson’s Intimacy vs. Isolation. Today, there is less stigma around someone choosing to not have a partner, so many people are more focused on independence and planning ahead. The stages in both models describing people in their 40s to 60s emphasize how these people want to learn new skills, but are either limited by age or external factors. Your final stage is different than Erikson’s, but I think plays a major role in the lives of the elderly. Memory greatly affects their lives and alters how they perform daily tasks. Thanks for sharing your ideas. The descriptions behind them are similar to that I have observed in my life.
