人的大脑从什么年龄段开始“偷懒”? 先来个小测试:你觉得大脑从什么时候开始衰老? 答案:20多岁! 没错,就在你纠结“中午吃啥”的时候,你的大脑已经开始“衰退之旅”——神经元连接减少、记忆力逐渐“掉线”,甚至为未来的阿尔茨海默病埋下隐患。 阿尔茨海默症的最大风险因素是什么? 阿尔茨海默症的最大风险因素不是年龄,而是大脑老化的速度。 根据世界卫生组织2021年的数据,全球范围内,患有痴呆症的人数已超 5500 万。预计到 2050 年将飙升至 1.39 亿 。尤其当祖辈或家属中有阿尔茨海默症患者时,由于携带致病基因,这类人未来患痴呆症症的风险会显著增高。 漫漫人生,能够常伴我们的始终是自己。但是,如果患上阿尔茨海默症,在晚年失去独立生活能力,那情何以堪? 不过,别担心:根据科学研究表明约 40% 的大脑老化受生活方式影响,这意味着我们有能力减缓大脑老化进程。也就是说如果能跟踪大脑随时间的老化情况,并衡量生活方式的改变是否有效延缓了大脑衰老。 如何判断你的大脑是否健康? 时钟绘制测试(Clock Drawing Test) 先来做一个小测试,叫做画钟测试(Clock Drawing Test),这个测试能在很短的时间内测试受试者的大脑的四大核心功能。画钟测试在80%的痴呆早期筛查中有效,且比单纯问卷更客观! 请在一张白纸上画一个圆形时钟,并完成以下任务: 测试原理:暗藏玄机的“时钟” 这个看似简单的任务,其实综合评估了大脑的 4大核心功能: ✅ …

Schwartz,因在法庭上提交了由AI生成的虚假信息,被罚款5000美元。 2023年,Schwartz 律师代理客户罗伯托·马塔 (Roberto Mata) 起诉哥伦比亚航空公司。案件起因是马塔在飞行中被金属餐车撞伤膝盖。Schwartz 律师使用 ChatGPT 进行法律研究,并在法庭简报中引用了多个“案例”。然而,法官发现这些案例在法律数据库中根本不存在。 事后,Schwartz 律师回忆,他特意询问 ChatGPT 这些案例是否真实,AI信誓旦旦地给出了肯定答复。结果,他却被AI“坑”了。 今天,我们就来聊聊 AI 幻觉 —— 为什么AI会“胡说八道”,以及如何避免被它“忽悠”。 什么是 AI 幻觉?
