Varying degrees of organization of verbal material were presented to determine their use in sentence reproduction by acute and chronic schizophrenic subjects, a psychiatric (alcoholic) control group, and a healthy control group. The material consisted of six-word sentences presented over earphones, with background noise of differing intensity. The main result was that schizophrenics use verbal organization as effectively as healthy and psychiatric controls when reproducing the sentences. The noise distraction influenced performance of all groups similarly. Results suggest that performance of schizophrenics is facilitated by structured material (semantic and syntactic organization). The results do not suggest that either the linguistic repertoire or the application of linguistic rules is specifically affected in schizophrenia. The flatter performance slope of schizophrenics with increasing contexual constraints, found by some researchers, is explained by the unspecific effect of task difficulty.
向不同程度语言材料组织形式的对象呈现材料，以确定其在急性和慢性精神分裂症患者、一个精神科（酗酒）对照组以及一个健康对照组进行句子复述时的使用情况。材料由通过耳机呈现的六词句子组成，伴有不同强度的背景噪音。主要结果是，精神分裂症患者在复述句子时使用语言组织的效果与健康人和精神科对照组一样有效。噪音干扰对所有组的表现影响相似。结果表明，结构化材料（语义和句法组织）有助于精神分裂症患者的表现。结果并未表明精神分裂症患者的语言储备或语言规则应用受到了特异性影响。一些研究人员发现，随着语境限制增加，精神分裂症患者表现的斜率更为平缓，这是由任务难度的非特异性效应所解释的。
