Mothers' actions are more enthusiastic, simple, and repetitive when demonstrating novel object properties to their infants than to adults, a behavioral modification called "infant-directed action" by Brand and colleagues (2002). The current study tested whether fathers also tailor their behavior when interacting with infants and whether this modification differs from the infant-directed action that mothers show. A sample of 42 parents (21 mothers and 21 fathers) demonstrated the properties of two novel toys to their infants (12-month-olds) and to other adults. Fathers and mothers modified their actions with respect to repetitiveness, rate, range of motion, proximity, interactiveness, and enthusiasm compared with interactions with other adults. Fathers differed from mothers with respect to proximity, carrying out actions closer to their infants than mothers did. These results provide evidence that fathers show modifications in their infant-directed action that is similar to that of mothers.
母亲在向婴儿展示新物体的属性时,其动作比向成人展示时更热情、简单且重复,这种行为被 Brand 等人(2002 年)称为“婴儿导向动作”。本研究测试了父亲在与婴儿互动时是否也会调整自己的行为,以及这种调整是否与母亲表现出的婴儿导向动作不同。42 名父母(21 名母亲和 21 名父亲)向他们的婴儿(12 个月大)和其他成人展示了两个新玩具的特性。与与其他成人的互动相比,父亲和母亲在重复性、速度、运动范围、接近度、互动性和热情方面改变了他们的动作。与母亲相比,父亲与婴儿的距离更近,其动作更接近婴儿。这些结果表明,父亲在其婴儿导向动作中表现出与母亲相似的调整。
