Escape Extinction is implemented when:

Escape extinction is a process used in behavior modification where an individual learns that engaging in a certain behavior will not result in the escape from an aversive situation or task. In this context, the correct answer highlights that the aversive task is not removed following the behavior. This means that when the individual emits the behavior that is typically reinforced through escape, the consequence of not escaping reinforces the understanding that the behavior will not yield the desired outcome.

For example, if a child consistently avoids doing their math homework by crying, implementing escape extinction would entail requiring the child to complete the homework regardless of their crying. By doing so, the child learns that crying will not result in the homework being removed, ultimately reducing the crying behavior over time.

The other options describe scenarios that do not align with the principles of escape extinction. Providing consistent reinforcement maintains the behavior instead of diminishing it. Making positive reinforcement available does not directly involve the aversive stimulus and could actually encourage the behavior associated with escape. Increasing negative reinforcement would not promote extinction either, as it would still involve escape from an aversive condition, thereby reinforcing the behavior.
