55 healthy infants were assessed for their developmental and behavioral patterns at the age of 9 mo. Hand preference was assessed at 20 mo. of age. The distribution of hand preference showed 12 were right-handed, 11 left-handed and 23 ambidextrous. This distribution appears shifted more to the left than that reported for older children. Although their data were based on different tests not appropriate for 9-mo.-old infants, ambidexterity appeared to reflect part of the hand-preference continuum. No significant relationship between hand preference and developmental attainments was noted. Perhaps a larger sample would provide a clear developmental behavioral pattern and hand preference in infancy.
对55名健康婴儿在9个月大时的发育和行为模式进行了评估。在20个月大时评估了用手偏好。用手偏好的分布显示，12人惯用右手，11人惯用左手，23人双手灵活。这种分布似乎比报道的大龄儿童更偏向于左利手。尽管他们的数据基于不适用于9个月大婴儿的不同测试，但双手灵活似乎反映了用手偏好连续体的一部分。未发现用手偏好与发育成就之间存在显著关系。也许更大的样本会提供婴儿期清晰的发育行为模式和用手偏好。
