The correct answer is Erik Erikson

Erickson argues that the behavior-activating energy is psychosocial in nature, integrating not only biological and innate drive factors, such as libido, but also social factors, learned in specific historical-cultural contexts.

One of the fundamental concepts in Erickson's theory is that of crisis or conflict that the individual lives through the periods he goes through, from birth to the end of life. Each conflict must be resolved positively or negatively by the individual.
