Using eye tracking, we investigated if 10-month-old infants could discriminate between members of a set of small forms based on geometric properties in a deviant-detection paradigm, as suggested by the idea of a core cognitive system for Euclidian geometry. We also investigated the precision of infants' ability to discriminate as well as how the discrimination process unfolds over time. Our results show that infants can discriminate between small forms based on geometrical properties, but only when the difference is sufficiently large. Furthermore, our results also show that it takes infants, on average, <3.5 s to detect a deviant form. Our findings extend previous research in three ways: by showing that infants can make similar discriminative judgments as children and adults with respect to geometric properties; by providing a first crude estimate on the limit of the discriminative abilities in infants, and finally; by providing a first demonstration of how the discrimination process unfolds over time.
我们采用眼动追踪技术，研究了10个月大的婴儿是否能够像欧几里得几何核心认知系统理论所认为的那样，在异常检测范式中基于几何属性区分一组小图形中的不同成员。我们还研究了婴儿区分能力的精确程度，以及区分过程是如何随时间展开的。我们的研究结果表明，婴儿能够基于几何属性区分小图形，但前提是差异要足够大。此外，我们的研究结果还表明，婴儿平均需要不到3.5秒就能检测出异常图形。我们的研究结果在三个方面扩展了先前的研究：一是表明婴儿在几何属性方面能够做出与儿童和成人相似的辨别判断；二是首次对婴儿辨别能力的极限进行了粗略估计；最后，首次展示了辨别过程是如何随时间展开的。
