Donna works in an auditing firm and her manager is extremely happy with the quality of her work. when the department head sends out an e-mail highlighting the common errors made while auditing a client's files, donna does not bother to read the e-mail. this is because she knows that those errors were not made by her. this scenario best exemplifies:

This is an example of selective perception. During this scenario, Donna is understanding that the errors made in the audit were not of her doing, so taking the time to perceive the errors and trying to rectify them would simply be a waste of her (and the company's) time and resources. By selectively attenuating to certain topics and not bothering with others, she is making the best use of her time.
