A factor analysis of reaction time crossover data of 53 schizophrenic patients, 45 first-degree relatives, and 38 controls, previously reported by De Amicis and Cromwell, was performed in order to shed light upon the relationship of crossover to aging, mean reaction time, and general socioeconomic functioning. The aging factor shared variance with getting married and having children, but not with reaction time crossover. Crossover was also found to be independent of reaction time speed among first-degree relatives and control subjects; however, it was correlated with reaction time speed among actively symptomatic schizophrenic patients. Additionally, the relationship of crossover to socioeconomic functioning was found to be negative among the patients, positive among the relatives, and nonexistent among control subjects. Results are discussed in terms of previous reports of higher than normal functioning found in relatives of schizophrenic patients.
对先前由德阿米西斯和克伦威尔报告的53名精神分裂症患者、45名一级亲属和38名对照者的反应时间交叉数据进行了因子分析，以便阐明交叉与衰老、平均反应时间和一般社会经济功能之间的关系。衰老因子与结婚和生育共享方差，但与反应时间交叉无关。在一级亲属和对照者中，交叉也被发现与反应时间速度无关；然而，在有明显症状的精神分裂症患者中，交叉与反应时间速度相关。此外，发现交叉与社会经济功能的关系在患者中为负，在亲属中为正，在对照者中不存在。根据先前关于精神分裂症患者亲属中发现高于正常功能的报告对结果进行了讨论。
