Psychologist Erik Erikson developed his eight stages of development to explain how people mature. The stages clarify the developmental challenges faced at various points in life. His theory is widely taught in developmental psychology courses in the United States.
Charting the LifeCourse frames life in six life stages that intersect with six life domains. Here, understand the life stages. Life stages are the ages and stages we go through as we learn and grow, from infancy to adulthood.
Biologists recognize 12 levels of organization in the living world. From the simplest to the most complex, these levels include atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and finally biospheres.
What are the six stages of the human life cycle? The six stages of human development include the foetus, infancy, toddler years, childhood, puberty, adolescence, adulthood, middle age and senior years.
Understanding Erikson's 8 Stages of Development. Erikson's theory suggests that your ego identity develops throughout your entire life during eight specific stages: Infancy – Basic trust versus mistrust. Toddler – Autonomy versus shame and doubt.
Stages of Adulthood
A ninth stage was added by Erik Erikson's wife, Joan Erikson. It considers new challenges experienced with continued aging and incorporates aspects from all previous eight stages of psychosocial development.
A1 Main life stages: Infants (birth to 2 years) Early childhood (3–8 years) Adolescence (9–18 years) Early adulthood (19–45 years) Middle adulthood (46–65 years) Later adulthood (65+ years).
In summary, the human life cycle has six main stages: foetus, baby, child, adolescent, adult and elderly.
Stage 8: Integrity vs. Despair
The final psychosocial stage occurs during old age and is focused on reflecting back on life.2 At this point in development, people look back on the events of their lives and determine if they are happy with the life that they lived or if they regret the things they did or didn't do.
Description: The most important event at this stage is coming to accept one's whole lifeand reflecting on that life in a positive manner. According to Erikson,achieving a sense of integrity means fully accepting oneself and coming to termswith the death.
Generativity versus stagnation is the seventh stage of psychosocial development according to Erik Erikson. In this stage, adults strive to create or nurture things, often through parenting, contributing to the community, or some other positive change.
This is a time of many physical, mental, emotional, and social changes. Hormones change as puberty begins. Most boys grow facial and pubic hair and their voices deepen. Most girls grow pubic hair and breasts, and start their period.
Recent brain research indicates that birth to age three are the most important years in a child's development.
Parents may notice that around age 10, children start thinking and sounding almost “grown-up.” Children this age are on the cusp of adolescence and have the language skills and cognitive ability to gather information and formulate well-organized opinions and thoughts.
The then describes life at the following levels; atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system, organisms, population, community, ecosystem, biome and finally biosphere.
Linnaeus' hierarchical system of classification includes seven levels. They are, from largest to smallest, kingdom, phylum, class, order, family, genus, and species.
Explanation. There are 13 levels of organization. In sequence, they are represented as atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, population, community, ecosystem, biome, and biosphere.
