We've all turned to sad music to make us feel (good)at some point in our lives, but why does doubling down on the sadness help drag us out of the mire(泥沼)？
A new study sheds light on what's going on inside our brains we match our music to our feelings. It looks like sad music can be enjoyable -rather than (simple) depressing- because it triggers positive memories that can help to lift our mood. Psychologist Adrian North from Curtin University in Australia says there (be)two groups of possible (explain)for why we enjoy listening to sad music like this: one from social psychology, and one from cognitive neuroscience(认知神经学).
In terms of social psychology, one way of (think) about this is that we feel much better about (we) if we focus on someone who's doing even worse, a process known as downward social comparison. Everything's going to be okay, because this person (have) an even worse day than you are.
Another theory from social psychology is
that people like to listen music that mirrors the tone of their
current life circumstances -the songs act as sort of tuning fork(音叉) for our own situations and they
resonate(共鸣)
with us
