儿童对计数的重要意义的理解通常通过“给x”任务来评估，在该任务中，他们被归类为“计数器”或“抓取器”。以前的研究表明，一个突然的阶段性转变，意味着对一个原则的洞察。采用微观遗传学方法，本研究旨在探讨这种二分法是否掩盖了更微妙的模式。55名39至58个月奥尔兹接受了5次“给予x”试验，涉及4、5、6、7和10个对象，在一次单独的会议中，每个孩子参加两次类似的会议，间隔一周。记录儿童的自发策略。他们还完成了一个简单的口头计数测试。参与者很少简单地“抓住”;即使是那些从不计数的人也会一个接一个地给出物品。有些人给出了正确的数量，开始计数，然后默默地把余数拿走，这表明内部计数。还有证据表明，儿童服用了正确的不可subitizable数量，而没有公开计数。个体的策略选择和他们使用特定策略的方式在会话内和会话之间都是不同的。此外，在达到程序掌握后，儿童继续完善他们对策略的使用。结果与Karmiloff-Smith的RR模型和Siegler的重叠波模型进行了讨论。版权所有© 2007约翰威利父子有限公司。
Children's understanding of the cardinal significance of counting is often assessed by the ‘give x’ task, in which they are categorized as ‘counters’ or ‘grabbers’. Previous research indicates a sudden stage‐like shift, implying insight into a principle. Employing a microgenetic approach, the present study was designed to explore whether this dichotomy masks a more subtle pattern. Fifty‐five 39‐ to 58‐month‐olds received five ‘give x’ trials, involving 4, 5, 6, 7, and 10 objects, within a single session counterbalanced across individuals, each child participating in two similar sessions one week apart. Children's spontaneous strategies were recorded. They also completed a simple verbal counting test. Participants seldom simply ‘grabbed’; even those who never counted gave items one‐by‐one. Some gave correct amounts by starting off counting then taking the remainder silently, suggesting internal counting. There was also evidence of children taking correctnon‐subitizable quantities without overtly counting. Individuals' strategy choice and the way they employed particular strategies varied, both within and between sessions. Furthermore, after achieving procedural mastery, children continued to refine their use of strategies. The results are discussed in relation to Karmiloff‐Smith's RR model and Siegler's overlapping waves model. Copyright © 2007 John Wiley & Sons, Ltd.
