The Dot Enumeration Perceptual Organization Task (DEPOT) evaluates the validity of 2 specific competing cognitive models of early input dysfunction in schizophrenic individuals: a primary Stage 1, sensory store, perceptual organization deficit vs. a Stage 2, short-term visual memory (STVM) deficit. DEPOT was also designed to assess the hypothesis that schizophrenic individuals tend to perform poorly on all cognitive tasks. In DEPOT both number and form judgments are made about the same dot patterns. A response delay manipulation assesses the persistence and operation of STVM. The study included 41 psychotic inpatients (8 with acute and 16 with chronic schizophrenia and 7 with bipolar and 10 with nonbipolar affective disorder) and 38 controls (22 college students and 16 hospital personnel). Although the pattern of results was consistent with neither the Stage 1 deficit nor the general deficit hypotheses, a Stage 2, STVM deficit hypothesis could account parsimoniously for the data.
点枚举感知组织任务（DEPOT）评估了精神分裂症患者早期输入功能障碍的两种特定相互竞争的认知模型的有效性：一种是主要的第1阶段，感觉存储、感知组织缺陷，另一种是第2阶段，短期视觉记忆（STVM）缺陷。DEPOT还旨在评估精神分裂症患者在所有认知任务上往往表现不佳这一假设。在DEPOT中，对相同的点模式进行数量和形式判断。反应延迟操作评估STVM的持续性和运作情况。该研究包括41名精神病住院患者（8名急性精神分裂症患者、16名慢性精神分裂症患者、7名双相情感障碍患者和10名非双相情感障碍患者）和38名对照者（22名大学生和16名医院工作人员）。尽管结果模式既不符合第1阶段缺陷假设，也不符合一般缺陷假设，但第2阶段的STVM缺陷假设可以简洁地解释这些数据。
