摘　　要：选取127名儿童完成数字线估计任务,探讨其在不同类型的复杂情境中对熟悉数字的估计策略。两个实验分别要求儿童对10cm长度下的不同范围(0~50和0~100),以及不同长度(10cm和18cm)对0~100范围的数字进行估计。结果显示儿童对0~50估计时绝对误差百分比曲线呈直线上升型,而对0~100范围的数字估计呈“M”型。针对范围和长度的变化,儿童分别采取心理长度和比例判断等估计策略,但受不同范围的影响更大。这表明儿童会根据具体情境灵活选择不同的估计策略,为重叠波理论提供了新的证据。The purpose of this study was to explore the representation models and estimation strategies in complex situations.A total of 127 children were selected to perform the number line estimation task.In two experiments,children were asked to estimate the position of numbers at different ranges(0~50 and 0~100)for a number line length of 10 cm and at different lengths(10 cm and 18 cm)for a number range of 0~100.The results showed that the absolute error percentage curve for children's estimation of 0~50 shows a straight line ascending,while the 0~100 shows an"M-shaped"pattern.Regardless of the change in number range or number line length,children can use estimation strategies such as mental length and proportion judgment,but they were more affected in different number ranges.These findings suggested that children can flexibly choose different estimation strategies according to the specific situation,which provides new evidence for overlapping wave theory.
