What is different are the subjects\u2019 responses. There is <strong>NO SPONTANEOUS RECOVERY<\/strong> for this group.

By contrast, the reactivation condition shows that, if the full memory is activated on Day 2 just before extinction, then the fear response does not spontaneously recover.<\/p>\r\n<p>However, our journey is not quite complete. The experimenters claim that a reactivated memory acts like a new memory: it is open to change for only a brief time and then it becomes stable again. So the Day 2 extinction process should only work to change the original memory for a short while\u2014at most, a few hours. If the memory is reactivated, but extinction is delayed for a few hours, then the memory should not be changed because it has had time to reconsolidate. Let's see if this was the case.<\/p>\r\n<h2>The Delay Group<\/h2>\r\n<p>The final experiment tests this idea. The only difference between this new group and the last group is the time delay on the second day. Rather than waiting 10 minutes between reactivating the memory and extinction, the experimenters waited 6 hours. After 6 hours, the fear memory should no longer be active and extinction should not change the memory.<\/p>\r\n<section class=\"textbox connectIt\">\r\n<h3>Day 1 - 6-Hour Group<\/h3>\r\n<p>Day 1 for this new group is exactly the same as Day 1 for both of the previous groups.
