我们研究了60例局限于大脑4个象限中的1个象限的弹射伤患者。所有患者均经神经外科检查其病变范围。采用WAIS（韦氏成人智力量表）块设计和对象组装子测试和Bender格式塔测试研究建构性失用症的发生率和严重程度。一个一致显著的尾性效应得到，越后定位病变导致更严重的结构性失用。有右半球病变的患者在3项标准测量中有2项具有明显的侧偏效应，表现均较差。在所有的标准变量中，侧性效应的大小都小于尾性效应的大小。右后侧病变患者的结构性失用严重程度均大于其他象限位点的患者。在4个象限中，构造性失用的发生率如预期的那样变化，左侧前病变样本显示很少有构造性失用的证据，而右侧后病变样本显示这类缺陷的发生率很高。在所有样本中，显著的结构性失用症的绝对发生率都低得惊人。这一发现的部分原因可能是研究对象的年龄和总体健康状况良好，大多数受试者相对没有一般性认知障碍，以及病变的离散性。
Patients (60) with missile wounds confined to 1 of the 4 quadrants of the brain were investigated. All patients had neurosurgical verification of the limits of their lesions. The incidence and severity of constructional apraxia was studied using the WAIS [Wechsler Adult Intelligence Scale] Block Designs and Object Assembly subtests and the Bender Gestalt Test. A uniformly significant caudality effect was obtained, with more posteriorly localized lesions resulting in more severe constructional apraxia. A significant laterality effect was obtained on 2 of 3 criterion measures with uniformly inferior performance by patients with right hemisphere lesions. The magnitude of the laterality effect was less than that of the caudality effect for all criterion variables. The degree of severity of constructional apraxia in patients with right posterior lesions was uniformly greater than that of patients with other quadrant loci. The incidence of constructional apraxia in the 4 quadrants varied as expected with the left anterior lesion sample showing very little evidence of constructional apraxis, while the right posterior sample showed a high incidence of such deficits. The absolute incidence of significant constructional apraxia in all samples was surprisingly low. This finding might be partially accounted for by the age and general good health of the subjects studied, the relative absence of general cognitive impairment in the majority of subjects and the discrete nature of the lesions.
