本研究探讨了新生儿感知两大类简单形状（封闭和开放几何形状）之间的感知相似性的能力。三个实验进行了视觉配对比较任务。有证据表明，无论是封闭式或开放式的形式熟悉后，新生儿表现出一个新的类别，而不是一个熟悉的类别范例（实验1）的新奇偏好。这一结果既不能解释为新生儿无法区分简单几何形式的同一类别的实例（实验2），也不能解释为对新类别范例的自发偏好（实验3）。总体而言，研究结果显示，新生儿能够形成广泛类别的可区分的几何形状，依靠形状的感知相似性。
This study explored newborns' ability to perceive perceptual similarities between different exemplars of 2 broad classes of simple shapes: closed and open geometric forms. Three experiments were carried out using a visual paired-comparison task. Evidence showed that, after familiarization either to closed-shaped or to open-shaped forms, newborns manifested a novelty preference for a novel-category rather than for a familiar-category exemplar (Experiment 1). This result could not be explained either as a consequence of the newborns' inability to discriminate between instances of the same category of simple geometric forms (Experiment 2), or as a consequence of a spontaneous preference for the novel-category exemplars (Experiment 3). Overall, findings revealed that newborns are able to form broad categories of distinguishable geometric shapes by relying on the shapes' perceptual similarity.
