Erik Erikson's 8 Stages of Psychological Development

Erik Erikson, an American psychotherapist, established the notion of the eight ages of man in 1950, laying the groundwork for evolutionary psychology. In it, he claims that from birth to old age, we go through eight conflicts that allow us to grow psychosocially and personally. "We grow psychologically" when we encounter and effectively settle disagreement. However, if we cannot resolve these conflicts, we may not gain the required abilities to tackle what lies ahead.
