 An avoidance contingency is a contingency in which a response prevents or postpones the presentation of a stimulus. Fuck it, I'm out! An example of an avoidance contingency is putting your seatbelt on before the beeper goes off. You put the seatbelt in before the car beeped at you so you avoided the beep. Another avoidance contingency. You drive the speed limit to avoid a ticket. Sorry, it's just so short. Avoidance contingency, most important example. Letting a call from your mother-in-law go to voicemail.
