Proposed the "social actor interaction theory", that is, people will influence each other and make adjustments based on each other's feedback during interactions.

The "implying theory" is also proposed, that is, both parties in a conversation will use implicit information to convey emotions and intentions.

His thoughts have had a profound impact on the development of the field of interpersonal relationships and he is known as the founder of interpersonal theory.

In 1922, with funding from the Rockefeller Foundation, Elton Mayo immigrated to the United States and taught at the Wharton School of Management at the University of Pennsylvania.

During this period, Elton Mayo once explained the behavior of industrial workers from a psychological perspective, believing that the influencing factors were multiple and no single factor could play a decisive role. This became the theoretical basis for his later classification of organizations as social systems.

In 1923, Elton Mayo conducted an experimental study on the impact of workshop working conditions on worker turnover and productivity in a textile factory near Philadelphia.

In 1926, he entered Harvard University's School of Business Administration to specialize in industrial research, and worked at Harvard University until his retirement.
