It is interesting examining how the psychological landscape of the human mind changes in a lifetime. Many factors assist in uniquely developing the mind of an individual, and each individual transitions through the psychological states at times dependent on their biological make-up and life experiences. The following is my interpretation of the eight psychological stages of life:
Stage 1: Infancy (Birth – 2 years)
The psychological state of an infant is limited to basic survival instincts and the dependency to be cared for. This is a rapid stage of experiencing and processing completely new stimuli, including sensory information such as sights and sounds.
Stage 2: Early Childhood (2 years – 4 years)
This is when children are still heavily dependent upon their caretakers for survival. They do not understand societal rules. They can identify the sensory information they experience and associate this information with past experiences to infer meaning. Early language development is present.
Stage 3: Mid Childhood (4 years – 9 years)
Children can make the association between words and meaning. They have developed many self-sufficient tendencies and understand some social trends. They begin to develop many relationships with peers, rather than just caretakers. They are curious, and their minds are flexible enough to be taught in a learning environment.
Stage 4: Late Childhood (10 years – 13 years)
Children begin displaying signs of independence and uniqueness in personality. They question often and are easily taught new information. They have close relationships with peers and find a sense of individuality.
Stage 5: Puberty (13 years – 16 years)
At this stage, children experience angst. They want independence but are not usually able to be completely self-sufficient without direction. They begin to experience sexual desires. They are often faced with the difficulty of discovering where they fit in to society.
Stage 6: Early Adulthood (17 years – 25 years)
Adults are completely self-sufficient and strive for self-actualization. They can assess their lives and solve their problems. Often, they have adventurous and risk-taking tendencies, but also begin to desire stability.
Stage 7: Adulthood (25 years – 65 years)
This is the peak psychological state. Adults are self-sufficient, experienced, and strive for happiness. They are still capable of learning new things and retaining new information. They can care for others. They have many relationships in their lives. Stability is key to their mental health.
Stage 8: Seniority (65 years – Death)
In many ways, the psychological state of these adults begins to recede. Mental processes may slow or become inefficient. Things learned in early experiences of life, such as language and some life-sustaining habits, are still present. However, their psychological state can deteriorate so much that they will again need care and support from others to survive.
