The minimax problem states that optimal construct organization involves two limiting levels of "too many" and "too few" available construct, dimensions for flexible, accurate discrimination of interpersonal events. Measures of thought disorder derived from personal construct theory, such as the Bannister-Fransella Grid, detect only "too many" constructs. The present study (N = 60) hypothesized that Ss with the least and most number of Functionally Independent Constructs (FIC) would evidence more thinking errors characteristic of a schizophrenic thought disorder than would Ss between the minimum and maximum groups. A grid form of the Role Construct Repertory Technique and the Whitaker Index of Schizophrenic Thinking (WIST; Forms A & B) were administered to 60 psychiatric inpatients. FIC scores were used to assign the Ss to five levels of construct organization and WIST scores served as the dependent variable. Two WIST scores confirmed the experimental hypothesis.
极小极大问题表明，最优的构念组织涉及两个极限水平，即“太多”和“太少”的可用构念，这是灵活、准确地区分人际事件的维度。从个人构念理论衍生出的思维紊乱测量方法，如班尼斯特-弗兰塞拉格网，只能检测到“太多”的构念。本研究（N = 60）假设，功能独立构念（FIC）数量最少和最多的被试，相比于处于最少和最多组之间的被试，将表现出更多精神分裂症思维紊乱特有的思维错误。对60名精神科住院患者施测了角色构念 repertory 技术的网格形式和精神分裂症思维的惠特克指数（WIST；A 版和 B 版）。FIC 分数用于将被试分配到构念组织的五个水平，WIST 分数作为因变量。两个 WIST 分数证实了实验假设。
