Object play yields enormous benefits for infant development. However, little is known about natural play at home where most object interactions occur. We conducted frame-by-frame video analyses of spontaneous activity in two 2-h home visits with 13-month-old crawling infants and 13-, 18-, and 23-month-old walking infants (N = 40; 21 boys; 75% White). Regardless of age, for every infant and time scale, across 10,015 object bouts, object interactions were short (median = 9.8 s) and varied (transitions among dozens of toys and non-toys) but consumed most of infants’ time. We suggest that infant exuberant object play—immense amounts of brief, time-distributed, variable interactions with objects—may be conducive to learning object properties and functions, motor skill acquisition, and growth in cognitive, social, and language domains.

婴儿在家进行旺盛的物体游戏：大量的时间分布、可变的练习

物体游戏对婴儿的发展有巨大的好处。然而，人们对大多数对象交互发生的家中的自然游戏知之甚少。我们对 13 个月大的爬行婴儿和 13、18 和 23 个月大的步行婴儿进行了两次 2 小时的家访，对自发活动进行了逐帧视频分析（N = 40; 21个男孩；75% 白色）。无论年龄大小，对于每个婴儿和时间尺度，在 10,015 次对象回合中，对象交互都很短（中位数 = 9.8 秒）且变化多端（在数十个玩具和非玩具之间转换）但占用了婴儿的大部分时间。我们认为，婴儿丰富的物体游戏——与物体进行大量短暂的、时间分布的、可变的交互——可能有助于学习物体的特性和功能、运动技能的获得以及认知、社会和语言领域的发展。
