What concept describes the conditions under which people perform better based on their treatment?

The concept that describes the conditions under which people perform better based on their treatment is known as the Hawthorne Effect. This term originates from a series of studies conducted at the Hawthorne Works factory in the 1920s and 1930s. Researchers found that workers' productivity increased when they were aware that they were being observed, regardless of any specific changes made to their working conditions, such as lighting or breaks.

This phenomenon highlights the impact of psychological factors on human behavior in the workplace. When employees feel valued or noticed, their performance can improve as a response to this attention and the perceived concern for their well-being. The Hawthorne Effect emphasizes the importance of recognition and management's engagement with employees, suggesting that social factors and environment play a crucial role in motivation and productivity.

In contrast, the other choices reflect different concepts related to workforce management or motivation, rather than specifically addressing how performance is influenced by being treated or observed.
