Jared wants to eventually get Olivia to brush her teeth without him giving her a sticker.What should he do to increase the probability that Olivia does not stop brushing her teeth after he stops giving her stickers

A) Give her a sticker every single time she brushes her teeth.
B) Give her a bigger reward than a sticker.
C) Give her a sticker after a variable number of times she brushes her teeth.
D) Continue doing exactly the same thing he is currently doing.

Giving a sticker after a variable number of times she brushes her teeth would help Olivia develop a more intrinsic motivation to brush her teeth as opposed to only doing it for a reward. By varying the number of times she needs to brush her teeth for a sticker, it becomes less predictable and reinforces the behavior more effectively. Once she has developed a stronger habit of brushing her teeth on her own, Jared can gradually reduce the number of stickers given until eventually she is brushing her teeth without any external reinforcement.
