It has been shown that most human beings prefer to hold an infant on the left side of the body. Several factors may be responsible for this behavioural bias. The present study tested the role of emotion-perception asymmetries (assessed with a dichotic listening task) in infant holding-side preferences. In order to neutralise the influence of handedness, only left-handers were recruited. A sample of students was compared to a sample of mothers, with a view to demonstrating that hemispheric specialisation influences holding-side biases in left-handers only in a basic holding relationship (population of non-parents tested on an imagination task). The results confirmed the relationship between holding-side preferences and auditory-field advantages solely for students. The role of the holder's characteristics in determining of holding biases is discussed.
研究表明，大多数人喜欢将婴儿抱在身体左侧。这种行为偏好可能由多种因素导致。本研究测试了情绪感知不对称（通过双耳分听任务评估）在婴儿抱持侧偏好中的作用。为了消除利手的影响，仅招募了左利手者。将一组学生样本与一组母亲样本进行比较，目的是证明半球特化仅在基本抱持关系中（对非父母群体进行想象任务测试）影响左利手者的抱持侧偏好。结果仅证实了学生的抱持侧偏好与听觉场优势之间的关系。文中讨论了抱持者特征在决定抱持偏好方面的作用。
