I was disappointed to see that the researchers in this study excluded emotional memories when studying the hippocampus portion of the feeling brain. It isn’t that difficult to do, and makes me wonder why they and other researchers go to such lengths to avoid including emotions in their studies.

In other memory studies such as "Out-of-body–induced hippocampal amnesia" at http://www.pnas.org/content/111/12/4421, the researchers deemed emotional memories to be necessary in order to properly study the hippocampus, as evidenced by this statement about the experiment’s scripts: “..the selected life events had a moderate emotional level to ensure episodic long-term memory encoding.”

This study's exclusion of emotional memories yields questionable findings (such as that replaying made memories stronger) because the researchers thus have too narrow a basis for a finding about “memory” that could apply across the entire spectrum of what can be termed “memory.”
