Sarah and Holly started working at a Human Resources firm as recruiters on the same day and have the same position. Both women have been meeting their placement goals and are both very well liked within the organization.

Johnson, their supervisor, awarded Sarah the "Employee of the Month" award for her outstanding work. Which influence of perception is at work in this situation?
