Extinction Training During the Reconsolidation Window Prevents Recovery of Fear

Conditioned fear can be diminished through an inhibitory process called extinction, but can resurface under conditions such as the passage of time or exposure to stress. Our protocol presents a novel way of preventing fear recovery by introducing extinction during the reconsolidation window (the re-storage phase of a reactivated memory).

The History of Life on Earth Fossils of organisms that were different from anything alive today had been documented as early as the 17th century, but it was not until the early 19th century that scientists began to recognize that the successive layers of fossil bearing rocks were like successive pages in the history of life on earth. Although this recognition gave rise to the birth of the field of paleontology, the idea of complete global extinction of a species had yet to be fully accepted. At...

A Treatment Package without Escape Extinction to Address Food Selectivity

2015
Feeding difficulties are a common problem for children with developmental disorders, including autism, and behavioral interventions often include escape extinction. Recent research has begun to evaluate treatments that do not include escape extinction. This manuscript describes a multicomponent treatment package that does not use escape extinction to treat feeding difficulties.
FAQs
Extinction training forms a new inhibitory memory that competes with the original conditioned association. The earlier learning therefore remains available, while the newer memory can suppress the conditioned response when extinction conditions are present. This distinction helps explain why a response may decline during training yet reappear under different circumstances, making extinction a model of competing memories rather than simple forgetting.
The expression of extinction learning depends on more than the cue itself. Context can determine which memory is retrieved, timing can affect how the new learning is organized, and stress can alter whether the inhibitory memory controls behavior. Consequently, a reduced response observed during training may not generalize equally across settings or conditions.
Competition between the original association and the inhibitory memory allows behavior to remain flexible. An organism can reduce a response when an expected outcome no longer occurs while retaining information that the cue previously predicted that outcome. In neuroscience, this balance provides a framework for studying learning, memory, emotional regulation, and the conditions that support adaptation.
A basic procedure repeatedly presents a conditioned stimulus without the reinforcement or expected outcome that previously followed it. Researchers monitor whether the conditioned response decreases across these presentations and examine how well the change persists under different contexts, timing conditions, or stress levels. This workflow allows extinction to be studied as both behavioral change and memory formation.
Researchers use extinction training to investigate how fear-related learning and memory are regulated. By comparing responses before, during, and after nonreinforced cue presentations, they can examine the persistence of the original association and the effectiveness of the inhibitory memory. These experiments also support analysis of neural circuits involved in fear, learning, and memory.
Clinical exposure-based approaches are related to extinction training because they examine how responses change when expected negative outcomes do not occur. Extinction research can identify factors that strengthen more durable inhibitory memories, including the influence of context, timing, and stress. Such findings may help improve interventions for anxiety and trauma disorders without assuming that the original association has been erased.
