 A behavior chain interruption strategy is an intervention that relies on a participant's skill in performing the critical elements of a task. The chain is interrupted occasionally so that another behavior or an alternative behavior is omitted. Cool. So, an example of a behavior chain interruption strategy would be the classic label on a pack of cigarettes that you pull the pack out and take a look and go, well, this may cause cancer. And if the participant then puts the cigarettes down because of that warning stimulus, that is an effective behavior chain interruption strategy. However, I might add that they're completely ineffective. But it's an attempt and we can think of business for trying. I agree. The other one would be to deal with alcohol, same type of thing. Before a pregnant lady has a margarita, she should take effect that no pregnant lady should have consume alcohol for following reasons to do with babies.
