Models of the origin of left hand preference were tested with prospective data. Infants with and without a history of perinatal complications, matched for age, sex and parental handedness, were filmed at 6 weeks of age. Children with a history of perinatal complications lacked the rightward headturning bias of those children without a history of perinatal trauma. Children with a history of perinatal complications were also deviant with reference to the duration of a postural reflex and its degree of lateralization. Perinatal complications may delay the establishment of volitional hand use as well as increase the probability of left-handedness. The data were interpreted as supporting SATZ's (Cortex 8, 121-135, 1972) rather than BAKAN et al.'s (Neuropsychologia 11, 363-366, 1973) model of "pathological" left-handedness.
利用前瞻性数据对左手偏好起源的模型进行了测试。将有和没有围产期并发症史、年龄、性别和父母用手习惯相匹配的婴儿在6周龄时进行拍摄。有围产期并发症史的儿童缺乏无围产期创伤史儿童的向右转头偏好。有围产期并发症史的儿童在姿势反射持续时间及其偏侧化程度方面也存在异常。围产期并发症可能会延迟随意用手的建立,并增加左撇子的概率。这些数据被解释为支持萨茨(《皮质》8卷,第121 - 135页,1972年)而非巴坎等人(《神经心理学》11卷,第363 - 366页,1973年)的“病理性”左撇子模型。
