In comparison to a behavior that has been continuously reinforced, a behavior that has been intermittently reinforced will when reinforcement is stopped

The correct answer would be, decrease more rapidly.

Explanation:

In comparison to a behavior that has been continuously reinforced, a behavior that has been intermittently reinforced will decrease more rapidly when the reinforcement is stopped.

We can take an example of a trainer who trained a dog to shake hand with continuous reinforcement, when the reinforcement is stopped, the response of the dog is less likely to decrease because he has become trained to shake hand due to continuous reinforcement. But on the contrary, if the reinforcement was given intermittently, the response of the dog would most likely be decreased if the reinforcement if stopped.
