Eight-year-old children have a radically different learning strategy from twelve-year-olds and adults. Eight-year-olds learn primarily from positive feedback, whereas negative feedback scarcely causes any alarm bells to ring. Twelve-year-olds are better able to process negative feedback, and use it to learn from their mistakes. Adults do the same, but more efficiently. Dr Eveline Crone and her colleagues from the Leiden Brain and Cognition Lab used fMRI research to compare the brains of three different age groups: children of eight to nine years, children of eleven to twelve years, and adults aged between 18 and 25 years. This three-way division had never been made before; the comparison is generally made between children and adults. Crone herself was surprised at the outcome: "We had expected that the brains of eight-year-olds would function in exactly the same way as the brains of twelve-year-olds, but maybe not quite so well. Children learn the whole time, so this new knowledge can have major consequences for people wanting to teach children: how can you best relay instructions to eight- and twelve-year-olds?" The researchers gave children of both age groups and adults aged 18 to 25 a computer task while they lay in the MRI scanner. The task required them to discover rules. If they did this correctly, a tick appeared on the screen, otherwise a cross appeared. MRI scans showed which parts of the brain were activated. These surprising results set Crone thinking. "You start to think less in terms of ’good’ and ’not so good’. Children of eight may well be able to learn extremely differently, only they do it in a different way."
26. According to the talk, which of the following groups can best learn from their mistakes?
27. What is new about Dr. Crone’s research?
28. What had Dr. Crone and her colleagues expected?
29. Which of the following feedback can best stimulate the eight year-olds to learn?
30. According to the talk, which group of people would learn and benefit most?
选项
A、12-year-olds respond strongly to negative feedback.
B、12-year-olds function the same as 8-year-olds.
C、8-year-olds function almost the same as adults.
D、12-year-olds function almost the same as adults.
答案
B
解析
Crone博士和同事对结果也是大吃一惊,他们原本认为(had expected)8岁孩子与12岁孩子的大脑工作方式会完全一致,结果却不是。因此本题正确答案为B。
