Famous authors and artists are commonly photographed alongside a trusty mug of coffee, but that cup of joe is more likely to help the Great American Manager. Caffeine, it turns out, does not improve creativity, but it significantly enhances problem-solving, according to a new study. 著名作家和艺术家拍照时旁边经常会有一杯咖啡，但这杯咖啡更有可能会给这位美国好经理带来帮助。一项新的研究表明，咖啡因并不能提高创造力，但能显著提高解决问题的能力。 This is news, given how strongly we associate coffee with creative occupations and lifestyles. The study, published today in Consciousness and Cognition, followed 80 participants after they consumed either a placebo or 200 mg of caffeine—the equivalent of 12 ounces of coffee—and then tracked their problem-solving, creative idea generation, working memory, and mood. 考虑到我们平时以为咖啡和创造性职业以及生活方式有很大联系，所以这是个新发现。这项研究现在发表在《Consciousness and Cognition》上，在80名参与者分别喝了无效对照剂和200 mg咖啡因（相当于12盎司咖啡）之后，跟踪观察他们解决问题的能力、创意的形成、工作记忆力和情绪。 While problem-solving abilities improved significantly, the caffeine had no effect on memory or creativity. Subjects also reported feeling “less sad.” 解决问题的能力显著提高，但咖啡因对记忆力或创造力毫无影响。研究对象也说“忧伤感并未减少”。 |
