The Hawthorne effect is the most likely explanation for the increase in productivity and positive attitude. This effect refers to the phenomenon where the act of being observed or monitored can cause people to change their behavior and/or work harder. In this case, the workers were aware that they were being observed by Manuello while he was monitoring the computer system, which may have led to the increase in productivity and positive attitude.
