The exploratory behaviors of 60 5-month-old girls and boys were observed as they played with three unfamiliar toys and one familiar toy of their own during a laboratory session. Infants were seated at a table on the lap of an assistant. Each toy was placed on the table and remained there for 2 min after the infant first touched it. Frequency and duration of visual fixation on the toy, hand contact with the toy, five categories of lateralization, and eight categories of handling behaviors were measured. On the whole, the exploratory behaviors of girls and boys were not markedly different. However, girls spent more time than boys did in simultaneous hand contact with and visual fixation on their own familiar toy, whereas boys made more frequent contact with the familiar toy without visual fixation. In addition, boys displayed, overall, more tapping behaviors, and girls, more pinching and object-displacement behaviors. Girls and boys did not differ in manual lateralization. Results are discussed in reference to infants' rate of development, motor activity level, and girls' and boys' reactions to novelty.
在一次实验室活动中，观察了60名5个月大的女孩和男孩在玩三个陌生玩具和一个自己熟悉的玩具时的探索行为。婴儿坐在助手腿上的桌子旁。每个玩具放在桌子上，在婴儿第一次触摸后在那里放置2分钟。测量了对玩具的视觉注视频率和持续时间、与玩具的手部接触、五类偏侧化以及八类操作行为。总体而言，女孩和男孩的探索行为没有明显差异。然而，女孩比男孩花更多时间同时手部接触并视觉注视自己熟悉的玩具，而男孩在没有视觉注视的情况下更频繁地接触熟悉的玩具。此外，总体而言，男孩表现出更多的轻敲行为，女孩表现出更多的捏和物体移位行为。女孩和男孩在手动偏侧化方面没有差异。根据婴儿的发育速度、运动活动水平以及女孩和男孩对新奇事物的反应对结果进行了讨论。
