Definition
Aversive describes something causing avoidance of a thing, situation, or behavior by use of an unpleasant or punishing stimulus. Think of it as the opposite of appealing. It's what makes you want to steer clear. Aversive stimuli are often used in training, where negative consequences deter undesirable actions. Imagine the aversive feeling of touching a hot stove 🔥 or hearing nails scratch a chalkboard 😖.
