What I concluded from this piece of research with regards to memory is:
Short term stress improves memory
Long term stress negatively affects memory
I feel like this article was touching on common knowledge. When we talk about being exposed to an emotional stimuli and how this makes us hypervigilant, it makes us think of the concept of flight or fight. When we are faced with a stressful situation, our body prepares to fight or flight (run away) so it is only natural our senses become heightened.
An issue I had with this article is that it doesn't directly mention the effects of short term stress and long term stress. The experiment with the rats demonstrated it was constant stress they were put under compared to the experiment with human participants were stress was only short term.
I feel like the research is common knowledge but was interesting to read nonetheless.
