美国心理学家桑代克曾做过一个有趣的实验,实验要求被试者蒙上眼睛画4英尺长的线段,练习达3000次之多。A组被试者未能得到自己所画长度与目标4英尺之间的偏差的反馈,结果练习毫无进步。B组被试者每画一次都能得到及时、准确的反馈,结果进步迅速。①实验表明,准确、恰当的反馈,直接影响着人的后续行为。正因为反馈对个体学习有重要影响,所以反 American psychologist Thorndike has done an interesting experiment, the subjects asked the subjects covered in eyes painted 4-foot long line, practicing up to 3,000 times. The subjects in group A failed to get the feedback of the deviation between the length they painted and the target of 4 feet. As a result, the practice did not improve. Subjects in group B could get timely and accurate feedback every time they painted, resulting in rapid progress. ① experiments show that accurate and appropriate feedback, a direct impact on people’s follow-up behavior. It is precisely because feedback has an important impact on individual learning, so the opposite
