Figure 3. Selective episodic memory prioritization for threat withstands a variety of optimized extinction protocols.

Figure 3

A. A variety of extinction protocols did not weaken original fear memories. B. When data is combined from all one-day extinction protocols with event boundaries and 24-hour retrieval, the drop in CS+ memory from conditioning to extinction memory is unambiguous. C. Change point analysis shows a significant decrease in memory for items encoded immediately after the boundary (orange dotted line), preceding the decline in expectancy (gray dotted line) and arousal (red dotted lines) measured during encoding. Error bars reflect SEM; *** = P < .001; ** = P < .01; * = P < .05.
