今年的美国科学促进学会会议探讨了冬季天气、太阳能、臭烘烘的鬣狗、油画修复以及与婴儿交谈的重要性的问题。父母与孩子说得越多,孩子的词汇增长就会越快,其智力发育就会越好。这似乎是非常显而易见的,但直到1995年,科学研究表明这种差异开始发生作用的时期竞如此之早。当年,堪萨斯大学的贝蒂·哈特和托德·里斯利发表了一项长达10年的研究结果。在这项研究中,他们观察了堪萨斯城的42个家庭在家中如何交谈以及交谈多少。哈特博士和里斯利博士发现,在 This year’s meeting of the American Association for the Advancement of Science explores the issues of winter weather, solar energy, stinking hyenas, the importance of oil painting restoration and talking to babies. The more parents and children put it, the faster their children’s vocabulary will grow and the better their intellectual development will be. This seems quite obvious, but it was not until 1995 that scientific research showed that such a difference started to play its role earlier. That year, Betty Hart and Todd Risley of the University of Kansas released a 10-year study. In this study, they looked at how 42 families in Kansas City talked and talked at home. Dr. Hart and Dr. Risley found out
