Hormones are more likely to enhance memory,if our arousal level:
a)is high
b)is low
c)spikes and then levels off
d)remains moderate
I THINK A IS CORRECT ANSWER BUT I'M NOT SURE????
If you are talking about "flashbulb" memories — vivid images that are retained because the are so emotional — (Presidential assassination, shuttle explosion, 9/11), then I would agree with you. In these cases, stress hormones increase our arousal level and enhance the memory.
However, I don't know if this can be applied "across the board."
I hope this helps a little. Thanks for asking.
