2个实验中使用了数量任务报告来检验固有刺激组织对2个S组报告准确性的影响。每个实验中的受试者为 10 名精神分裂症患者和 10 名药物滥用住院患者（对照组）。在这两个实验中，都以速视方式呈现包含 0 到 6 条线的显示。在实验 I 中，线条要么单独出现，要么与噪声元素（圆圈）一起出现。当这些线条单独出现时，精神分裂症患者和对照组的表现相当。他们的报告准确性随着行数的增加而下降。在噪音条件下，只有精神分裂症患者的表现水平有所下降。在实验 II 中，刺激阵列不包含噪声元素。党卫队的任务是报告他们看到的所有线路。通过改变线元素的相似性和接近度来操纵阵列的感知组织。随着阵列的组织变得更加复杂，控制性能会恶化；精神分裂症患者不受该组织的影响。事实上，他们的平均表现明显优于对照组。两项实验的结果被解释为精神分裂症患者的知觉缺陷在于未能在处理的早期阶段组织信息的证据。（24 参考）（PsycINFO 数据库记录 (c) 2019 APA，保留所有权利）
A report of numerosity task was used in 2 experiments to examine the effect of inherent stimulus organization on the report accuracy of 2 S groups. Ss in each experiment were 10 schizophrenics and 10 drug abusing inpatients (controls). In both experiments, displays containing from zero to 6 lines were presented tachistoscopically. In Exp I, the lines appeared either alone or with noise elements (circles). When the lines appeared alone, schizophrenics and controls performed comparably. Their report accuracy decreased with increases in the number of lines. In the noise condition, the level of performance dropped only for schizophrenics. In Exp II, the stimulus arrays did not contain noise elements. Ss were given the task of reporting all the lines they saw. The perceptual organization of the arrays was manipulated by varying the similarity and proximity of the line elements. The performance of controls deteriorated as the organization of the arrays became more complex; schizophrenics were not affected by the organization. In fact, their average performance was significantly better than that of controls. Results of the 2 experiments are interpreted as evidence that schizophrenics' perceptual deficit lies in a failure to organize information at an early stage in processing.(24 ref)(PsycINFO Database Record (c) 2019 APA, all rights reserved)
