据报道，婴儿期的性别差异越来越多。其中一项任务是事件映射任务。在事件映射中，婴儿看到涉及1或2个物体的遮挡事件，遮挡物被移除，然后婴儿看到1个物体。通常，男孩比女孩更有可能检测到2对象遮挡事件和1对象显示之间的不一致。目前的研究调查了这种性别差异的根本原因。在9个月和4个月（平均年龄）的婴儿中进行了三次眼动追踪实验。婴儿看到一个球-盒或球-球闭塞事件，然后是一个1球显示;记录闭塞事件和1球显示的视觉扫描。年龄较大的男孩比年龄较大的女孩更有可能通过遮挡视觉跟踪对象，更有可能检测到球盒事件和1球显示之间的不一致。此外，通过遮挡追踪物体与婴儿对1球显示器的扫描有关。年龄较小的男孩和女孩都未能通过遮挡来跟踪物体，也未能检测到球盒事件和1球显示之间的不一致。这些结果表明，婴儿通过遮挡追踪物体的能力有助于提取婴儿可以映射到最终显示的初始事件的结构（即，所涉及的不同物体的数量），并且在4至9个月之间出现能力的性别差异。被认为是如何提取和映射的遮挡事件的结构的可能的解释。
A growing number of sex differences in infancy have been reported. One task on which they have been observed reliably is the event-mapping task. In event mapping, infants view an occlusion event involving 1 or 2 objects, the occluder is removed, and then infants see 1 object. Typically, boys are more likely than girls to detect an inconsistency between a 2-object occlusion event and a 1-object display. The current research investigated underlying reasons for this sex difference. Three eye-tracking experiments were conducted with infants at 9 and 4 months (mean age). Infants saw a ball-box or ball-ball occlusion event followed by a 1-ball display; visual scanning of the occlusion event and the 1-ball display was recorded. Older boys were more likely than older girls to visually track the objects through occlusion and more likely to detect an inconsistency between the ball-box event and the 1-ball display. In addition, tracking objects through occlusion was related to infants' scanning of the 1-ball display. Both younger boys and girls failed to track the objects through occlusion and to detect an inconsistency between the ball-box event and the 1-ball display. These results suggest that infants' capacity to track objects through occlusion facilitates extraction of the structure of the initial event (ie, the number of distinct objects involved) that infants can map onto the final display and that sex differences in the capacity emerge between 4 and 9 months. Possible explanations for how the structure of an occlusion event is extracted and mapped are considered.
