Hawthorne Effect:

The Hawthorne effect describes a temporary change to behavior or performance in response to a change in the environmental conditions, with the response being typically an improvement.

The Hawthorne studies have had a dramatic effect on management in organizations and how people react to different situations.

Although illumination research of workplace lighting formed the basis of the Hawthorne effect, other changes such as maintaining clean work stations, clearing floors of obstacles, and even relocating workstations resulted in increased productivity for short periods of time. Thus the term is used to identify any type of short-lived increase in productivity. In short, people will be more productive when appreciated or when watched.
