大量的研究表明，人类成年人将有序的信息映射到一个有方向的空间连续体上。我们问是否映射序数信息到一个方向空间构成了一个早期的倾向，已经功能之前的符号知识和语言的收购。虽然我们知道，前语言婴儿代表数字顺序沿着从左到右的空间连续体，还没有研究是否婴儿，像成年人一样，组织任何类型的顺序信息到一个有方向的空间。我们调查了7个月大的婴儿从几何形状的视觉序列中学习高阶规则样模式的能力是否受到序列的空间方向（从左到右与从右到左）的影响。结果表明，当视觉序列从左到右呈现时，婴儿很容易学习规则样模式，但从右到左呈现时则不然。这一结果提供的证据表明，空间取向决定了前语言婴儿感知和学习视觉序列中有序信息的能力，开放的想法，从左到右的空间组织有序尺寸的心理表征可能植根于生物学决定的人类大脑发育的限制。
A wealth of studies show that human adults map ordered information onto a directional spatial continuum. We asked whether mapping ordinal information into a directional space constitutes an early predisposition, already functional prior to the acquisition of symbolic knowledge and language. While it is known that preverbal infants represent numerical order along a left-to-right spatial continuum, no studies have investigated yet whether infants, like adults, organize any kind of ordinal information onto a directional space. We investigated whether 7-month-olds' ability to learn high-order rule-like patterns from visual sequences of geometric shapes was affected by the spatial orientation of the sequences (left-to-right vs. right-to-left). Results showed that infants readily learn rule-like patterns when visual sequences were presented from left to right, but not when presented from right to left. This result provides evidence that spatial orientation critically determines preverbal infants' ability to perceive and learn ordered information in visual sequences, opening to the idea that a left-to-right spatially organized mental representation of ordered dimensions might be rooted in biologically-determined constraints on human brain development.
