Results are presented from cross-sectional and longitudinal analyses of data from the Test of Behavioral Rigidity for 3,442 subjects over the age range from 22 to 84 years. Data are presented on the Behavioral Flexibility, Attitudinal Flexibility, and Social Responsibility questionnaire scales, as well as on performance score measures indexing Associational Flexibility, Instructional Set Flexibility, Copying Speed, and Associational Speed. Data on these scales were obtained for 5 samples examined 7 years apart (1956, 1963, 1970, 1977, and 1984). These data permit analyses of birth cohort differences and rate of change within the same individuals, as well as successive samples drawn from the same cohort over as long as 28-year periods. Results of the analyses confirm the presence of substantial generational differences, with generally only limited change over time within cohorts.
研究结果来自对3442名年龄在22岁至84岁之间的受试者进行的行为僵化测试数据的横断面分析和纵向分析。呈现了行为灵活性、态度灵活性和社会责任问卷量表的数据，以及索引联想灵活性、指令集灵活性、抄写速度和联想速度的表现得分测量数据。这些量表的数据是从相隔7年进行检查的5个样本（1956年、1963年、1970年、1977年和1984年）中获得的。这些数据允许分析出生队列差异以及同一个体内的变化率，以及从同一队列中抽取的长达28年的连续样本。分析结果证实了代际差异的存在，同一队列内随时间的变化通常有限。
