According to Mayo's research team, ___ in a test room resulted in higher productivity.

A) economic incentives
B) good human relations
C) scientific management
D) adequate rest pauses
E) timely measurement of production

Mayo's research team found that good human relations, such as better communication and positive interactions, led to higher productivity in the test room. This became known as the Hawthorne Effect. While economic incentives and timely measurement of production were also tested, they did not have as significant of an impact on productivity as the social factors of the Hawthorne Effect. Scientific management and adequate rest pauses were not specifically tested in this study.
