Answer:
The theory that the psychological development of children repeats the history of the human race is known as the Hall recapitulation theory, proposed by Stanley Hall.
Step-by-step explanation:
G. Stanley Hall, the founder of organized psychology, was inspired by Ernst Haeckel's theories on development to propose the theory known as the theory of recapitulation, which explains that an individual goes through important developmental changes as he or she grows that follow the history of evolution of the human's body and mind.
Hall stated that until the age of eight the child should have the freedom to express natural emotions, also referred as "animal emotions" as after this stage, the individual will develop formal learning. After this, the person will also develop morals.
Hall's work is extremely important in psychology. He was the president of the American Psychological Association and was extremely interested in the education of young people.
