Ifeel a bite and then see the dog that bit me. this is an example of a conditioning procedure which is to be effective.

backward; likely

Explanation:

In backward conditioning, we are exposed to the unconditioned stimulus  before we are aware of the  neutral stimulus. (in the example above, the bite is the unconditioned stimulus, and the dog is the neutral stimulus)

This type of conditioning is only 'Likely' to be effective because the person tend to do not see directly how the neutral stimulus cause the unconditioned stimulus.

Let's examine the example above again :

I feel a bite and then see the dog that bit me.

We can say that the person DO NOT directly witnessed the dog bited him/her. That person only guess that the dog is the one bited him/her since it's close. There is still a chance that the person's bitten by other animals.
