此前的研究表明，70%-85%的妇女和女孩倾向于将婴儿或玩偶抱在身体的左侧。这种偏见在男性中不能匹配(例如，德夏托，Holmberg Winberg，1978；Todd，1995)。本研究从大脑半球专门化角度对面孔表情知觉的摇篮偏好进行了解释。32名惯用右手的参与者接受了偏侧化的行为测试和一项摇篮任务。研究发现，左侧抱娃娃的女性比右侧抱娃娃的女性有更高的偏侧智商，而男性没有。结果表明，女性在身体一侧摇篮，而身体一侧是控制面部和情绪处理的大脑半球的对侧，这可能解释了摇篮发生率的性别差异。
Previous research has indicated that 70-85% of women and girls show a bias to hold infants, or dolls, to the left side of their body. This bias is not matched in males (e.g. deChateau, Holmberg Winberg, 1978; Todd, 1995). This study tests an explanation of cradling preferences in terms of hemispheric specialization for the perception of facial emotional expression. Thirty-two right-handed participants were given a behavioural test of lateralization and a cradling task. Females, but not males, who cradled a doll on the left side were found to have significantly higher laterality quotients than right cradlers. Results indicate that women cradle on the side of the body that is contralateral to the hemisphere dominant for face and emotion processing and suggest a possible explanation of gender differences in the incidence of cradling.
