The preattentive visual information processing of hypothetically psychosis-prone college subjects was evaluated using three different paradigms, target detection (n = 57), visual suffix effect (n = 57), and configural superiority effect (n = 68). It was hypothesized that anhedonic subjects would show the same perceptual organization deficits reported in process schizophrenics and that perceptual aberration-magical ideation subjects and depressed subjects would perform similarly to control subjects. In each study, anhedonics performed similarly to each comparison group, even though there was adequate power to detect performance differences if they existed. A framework for understanding the visual information-processing deficits of schizophrenics and high-risk subjects is proposed.
使用三种不同范式（目标检测，n = 57；视觉后缀效应，n = 57；构型优势效应，n = 68）对假设易患精神病的大学生的前注意视觉信息处理进行了评估。研究假设快感缺失的受试者会表现出与病程性精神分裂症患者中所报告的相同的知觉组织缺陷，并且知觉畸变-神奇观念的受试者和抑郁的受试者的表现会与对照组相似。在每项研究中，快感缺失者的表现与每个比较组相似，尽管如果存在表现差异，有足够的能力来检测到这些差异。本文提出了一个理解精神分裂症患者和高危受试者视觉信息处理缺陷的框架。
