Monocular eye-sighting preference was examined in 32 children with hemiplegia, 51 adult-onset hemiplegic patients and 57 normal children and adults. Eye preference was compared with ear preference on dichotic listening for 25 of the hemiplegic children. No independent association could be detected between eye preference and ear preference. In both the children and adults with hemiplegia the preferred eye tended to be on the same side as the damaged hemisphere. Among the adults, this tendency was more pronounced with more extensive lesions, as manifested by aphasia and/or hemianopia. These findings are interpreted as indicating that eye-sighting preference is unrelated to unitary hemispheric dominance, and that, unlike dominance for hearing and speech, it is not irreversible after a critical period of development. A simpler explanation than incomplete hemispheric dominance is offered for the weakly positive association between mixed laterality and cerebral dysfunction.
对32名偏瘫儿童、51名成人期偏瘫患者以及57名正常儿童和成人进行了单眼注视偏好检查。对25名偏瘫儿童进行了双耳分听测试，比较了他们的眼偏好和耳偏好。未发现眼偏好和耳偏好之间存在独立关联。在偏瘫儿童和成人中，优势眼往往与受损半球在同一侧。在成人中，随着病变范围扩大，这种倾向更为明显，表现为失语和/或偏盲。这些发现被解释为表明注视偏好与单一半球优势无关，并且与听力和言语优势不同，在发育关键期之后它并非不可逆转。对于混合性偏侧性与脑功能障碍之间的弱阳性关联，提供了一个比半球优势不完全更简单的解释。
