本研究考察了婴儿在静止的二维杆和箱展示中提取物体整体性的能力。婴儿对一根中心被遮挡的杆习惯化之后，分别用一根断开的杆和一根完整的杆进行测试。8个月大的男女参与者的注视模式都没有显示出能够在视觉上完成部分隐藏的杆的能力。然而，9个月大的女婴对断开的测试刺激的注视时间明显长于对完整测试展示的注视时间，这意味着她们将习惯化阶段呈现的部分被遮挡的杆感知为一个连接的整体。另一方面，同龄的男婴对测试图案没有区分。这些发现表明，在仅通过遮挡这一画面深度线索来确定表面相对深度顺序的展示中，感知物体整体性的能力在大约8个月大之后出现。此外，研究结果支持一种差异视角，即把性别作为一个调节变量。
The present study examined infants' capability of extracting object unity in a stationary two-dimensional rod-and-box display. The infants were habituated to a centre-occluded rod and were afterwards tested with both a broken rod and a complete rod. The looking pattern of both female and male participants aged 8 months did not reveal the ability to amodally complete the partly hidden rod. Nine-month-old females, however, looked reliably longer at the broken test stimulus than at the solid test display, implying that they had perceived the partially occluded rod presented in the habituation period as a connected whole. Their male counterparts, on the other hand, did not differentiate between the test patterns. These findings suggest that the capability of perceiving object unity in displays in which the relative depth ordering of surfaces is specified solely by the pictorial depth cue of interposition emerges after about 8 months of age. Furthermore, the results argue for a differential perspective including sex as a moderator variable.
