The difference between Hawthorne effect and Rosenthal effect

The difference between Hawthorne effect and Rosenthal effect lies in:

The Hawthorne effect focuses on the observed people, reflecting people's deep hope, hope to be appreciated, hope to show their best side and hope to show their feelings in society. In fact, it is more appropriate to change the observation here to concern, and the focus is on the behavior itself. Paying attention to behavior is not emotional.

The Rosenthal effect focuses on expectations and the interaction between the observer and the observed. The observer has positive expectations in his heart to treat the observed person, and the observed person will become more and more positive because he perceives this expectation revealed from the aspects of expression, movement and eyes. The emotional color of the observer plays a key role in it.

Introduction to Hawthorne effect: Hawthorne effect is an experimenter effect in psychology. In the 1920s-1930s, American researchers discovered the experimenter effect, called Hawthorne effect, in the experiment on the relationship among working conditions, social factors and production benefits in Hawthorne factory of Chicago West Electric Power Company.

In the first stage of the experiment, the relationship between working conditions and production benefits was set from 1924 1 1 to the experimental group and the control group. Results The output of the experimental group increased whether the light was increased or controlled, and so did the output of the control group with the same light. In addition, some factors such as salary, rest time, working hours per day and working days per week were also tested.
