Adversity, we are told, heightens our senses, imprinting sights and sounds precisely in our memories. But new Weizmann Institute research, which appeared in Nature Neuroscience this week, suggests the exact opposite may be the case: Perceptions learned in an aversive context are not as sharp as those learned in other circumstances.

“This likely made sense in our evolutionary past: If you’ve previously heard the sound of a lion attacking, your survival might depend on a similar noise sounding the same to you – and pushing the same emotional buttons. Your instincts, then, will tell you to run, rather than to consider whether that sound was indeed identical to the growl of the lion from the other day.”
