In positive reinforcement (see positive reinforcement) this represents an unconditioned stimulus that an organism will approach. The effectiveness of this stimulus can be modified and increased by deprivation. For example, hunger will increase the effectiveness of a desired type of food as an appetitive stimulus.

APPETITIVE STIMULUS: "The appetitive stimulus, for example, food, can be made more effective by depriving the organism of it beforehand."
