数字线估计(NLE)任务被广泛用于研究数字认知、学习和发展,并作为一种教学工具。对这些任务的解释通常涉及一种隐含的期望,即反应是由目标数字的总幅度驱动的,在某种意义上说,传达这些幅度的特定数字并不重要。然而,最近的证据表明,大小相似但最左侧数字不同的数字被估计的方式非常不同。例如,在7-11岁的儿童和成人的0-1000 NLE任务中,“798”被系统地放在“801”的左侧太远。在这里,我们要问的是,在0-100的非英语学习任务中,这种左数字效应是否推广到两位数字,以及它是否出现在年龄较小的儿童身上。5-8岁的儿童(研究1,N=673)、成年人(研究2,N=444)和9-11岁的儿童(研究3,N=727)在触摸屏平板电脑上完成了标准的0-100 NLE任务。我们在8-11岁的儿童和成人中观察到了两位数字的左数位效应,其效应大小较大,表明这些效应普遍存在于较小的数字范围内。左手指效应在5至7岁的儿童中并不明显,这表明这些效应在较小的、更熟悉的数字范围内不会在较小的年龄出现。我们讨论了数字线条估计中左数字效应的发展出现及其在认知发展领域内外的影响。
Number line estimation (NLE) tasks are widely used to investigate numerical cognition, learning, and development, and as an instructional tool. Interpretation of these tasks generally involves an implicit expectation that responses are driven by the overall magnitudes of target numerals, in the sense that the particular digits conveying those magnitudes are unimportant. However, recent evidence shows that numbers with similar magnitudes but different leftmost digits are estimated very differently. For example, “798” is placed systematically much too far to the left of “801” in a 0–1000 NLE task by children aged 7–11 and adults. Here we ask whether this left digit effect generalizes to two-digit numerals in a 0–100 NLE task and whether it emerges in younger children. Children aged 5–8 (Study 1,N= 73), adults (Study 2,N= 44), and children aged 9–11 (Study 3,N= 27) completed a standard 0–100 NLE task on a touchscreen tablet. We observed left digit effects for two-digit numerals in children aged 8–11 and adults, with large effect sizes, demonstrating that these effects generalize to smaller numerical ranges. Left digit effects were not apparent in 5- to 7-year-olds, suggesting that these effects do not emerge at younger ages for smaller, more familiar numerical ranges. We discuss developmental emergence of left digit effects in number line estimation and implications within and beyond the field of cognitive development.
