In psychology we use the term "positive humour style" to refer to（指代） people who use humour to enhance relationships and reduce conflict.
从心理学角度讲，我们用 “积极的幽默风格” 一词来指代那些用幽默提升人际关系和减少冲突的人。
This type of humour is associated with relationship satisfaction, extroversion（外向度） and high self-esteem.
这种幽默与人际关系的满意度、外向度和高自尊有关。
Having a humorous outlook on life is also a good coping strategy. It helps people better manage stress and adversity（逆境）.
幽默的生活观是一种很有用的应变策略，有助于人更好地应对压力和困境。
More negative humour styles, such as sarcasm（讽刺）, ridicule and self-defeating（弄巧成拙） humour, do not offer the same benefits.
而消极的幽默，比如讽刺、戏弄和适得其反的幽默，则没有这些好处。
Instead, they tend to alienate（使格格不入） people and are more often associated with depressed mood and aggression.
反而让人格格不入，更可能陷入抑郁和暴躁的情绪状态。
Not only do funny people make other people laugh, they also laugh more themselves.
幽默的人不仅给别人带来欢乐，也让自己更开心。
And neurobiology（神经生物学） shows that laughter leads to brain changes, which may explain the link between humour and intelligence.
神经生物学研究显示，大笑会使大脑发生变化，这或许可以解释幽默与智力的关联性。
Neuropsychological studies have found that experiencing positive emotional states, such as joy, fun and happiness, increases the production of dopamine（多巴胺） in the brain.
神经心理学研究显示，积极的情绪状态，比如喜悦、欢乐和开心，能使大脑分泌更多的多巴胺。
Dopamine not only makes us feel great, it also opens up the learning centres of the brain, which enables and sustains more neural connections.
多巴胺不仅让人心情愉悦，还会打开大脑的学习中枢，联结更多的神经元，维持这些神经结点。
As a result, we become more flexible and creative in our thinking, and better at solving problems.
由此，我们的大脑在思考问题时会更加灵活，更有创造力，解决问题的能力也更强。
