We examined the effects of several variations in response rate on the calculation of total, interval, exact-agreement, and proportional reliability indices. Trained observers recorded computer-generated data that appeared on a computer screen. In Study 1, target responses occurred at low, moderate, and high rates during separate sessions so that reliability results based on the four calculations could be compared across a range of values. Total reliability was uniformly high, interval reliability was spuriously high for high-rate responding, proportional reliability was somewhat lower for high-rate responding, and exact-agreement reliability was the lowest of the measures, especially for high-rate responding. In Study 2, we examined the separate effects of response rate per se, bursting, and end-of-interval responding. Response rate and bursting had little effect on reliability scores; however, the distribution of some responses at the end of intervals decreased interval reliability somewhat, proportional reliability noticeably, and exact-agreement reliability markedly.
我们考察了几种响应率变化对总可靠性、间隔可靠性、精确一致可靠性和比例可靠性指数计算的影响。训练有素的观察者记录出现在计算机屏幕上的计算机生成的数据。在研究 1 中，目标响应在单独的会话中以低、中、高的速率发生，以便可以在一系列值上比较基于这四种计算的可靠性结果。总可靠性始终很高，高响应率时的间隔可靠性会产生偏差，高响应率时的比例可靠性会稍低，而精确一致可靠性则是这些指标中最低的，尤其是在高响应率时。在研究 2 中，我们分别考察了响应率本身、突发和间隔结束时的响应对可靠性分数的影响。响应率和突发对可靠性分数几乎没有影响；然而，间隔结束时的一些响应的分布会稍微降低间隔可靠性、显著降低比例可靠性和明显降低精确一致可靠性。
