这篇简短的报告试图解决婴儿优先关注连续变量而不是数字的说法。自然科学10 (1999)408；Cognit。心理学。44(2002)33]发现，当连续变量受到控制时，6个月大的婴儿就能辨别出大的数值[例如心理学]。科学14 (2003)396；认知89 (2003)1315；认知74 (2000)[b]。在两个平行实验中，我们比较了6个月大的婴儿区分数字和忽略连续变量的能力，以及他们形成累积表面积表征和忽略数字的能力。我们发现婴儿在数量上区分了2倍的变化，但不能区分累积表面积的2倍变化。结果表明，离散和连续维度之间的关系比以前的文献所暗示的更为复杂。(C) 2004年Elsevier B.V.出版
This brief report attempts to resolve the claim that infants preferentially attend to continuous variables over number [e.g. Psychol. Sci. 10 (1999) 408; Cognit. Psychol.44 (2002) 33] with the finding that when continuous variables are controlled, infants as young as 6-months of age discriminate large numerical values [e.g. Psychol. Sci. 14 (2003) 396; Cognition 89 (2003) 1315; Cognition 74 (2000) B1]. In two parallel experiments, we compare 6-month-old infants' ability to discriminate number and ignore continuous variables with their ability to form a representation of a cumulative surface area and ignore number. We find that infants discriminate a 2-fold change in number but fail to discriminate a 2-fold change in cumulative surface area. The results point to a more complicated relationship between discrete and continuous dimensions than implied by previous literature. (C) 2004 Published by Elsevier B.V.
