Although a growing number of studies indicate that simple strategies, intuitions, or cognitive shortcuts called heuristics can persistently interfere with scientific reasoning in physics and chemistry, the persistence of heuristics related to learning biology is less known. In this study, we investigate the persistence of the "moving things are alive" heuristic into adulthood with 28 undergraduate students who were asked to select between two images, one of which one represented a living thing, while their electroencephalographic signals were recorded. Results show that N2 and LPP event-related potential components, often associated with tasks requiring inhibitory control, are higher in counterintuitive trials (i.e., in trials including moving things not alive or nonmoving things alive) compared with intuitive ones. To our knowledge, these findings represent the first neurocognitive evidence that the "moving things are alive" heuristic persists into adulthood and that overcoming this heuristic might require inhibitory control. Potential implications for life science education are discussed.
尽管越来越多的研究表明,简单的策略、直觉或被称为启发式的认知捷径会持续干扰物理和化学领域的科学推理,但与生物学学习相关的启发式的持续存在却鲜为人知。在这项研究中,我们调查了“移动的东西是有生命的”这一启发式在成年人中的持续存在,我们邀请了 28 名本科生参与研究,要求他们在两张图片之间进行选择,其中一张代表有生命的东西,同时记录他们的脑电图信号。结果表明,与直觉相符的试验(即包括移动但没有生命的东西或不移动但有生命的东西的试验)相比,在违背直觉的试验中,N2 和 LPP 事件相关电位成分更高,这些成分通常与需要抑制控制的任务相关。据我们所知,这些发现代表了第一个神经认知证据,证明“移动的东西是有生命的”这一启发式会持续到成年期,并且克服这种启发式可能需要抑制控制。文章还讨论了这些发现对生命科学教育的潜在影响。
