A time-estimation task was considered for inclusion in the Performance Evaluation Tests for Environmental Research (PETER) battery. As part of this consideration, the effects of repeated testing on the reliability of time judgments were studied. The method of production was used to estimate eight time intervals. Five trials per day at each interval were administered individually to each of 19 subjects for 15 consecutive workdays. Two scores, constant error and variable error, were reported. The effect of days was not significant for constant error and was moderate for variable error (p < .04). The standard deviations were relatively stable across trials. A pronounced decline in reliability over repeated days of testing was found for both errors. It was concluded that this time-estimation test would be a poor candidate for inclusion in PETER, but further research is warranted because of the potential unique contribution of a time-estimation task in a performance test battery.
一项时间估计任务被考虑纳入环境研究性能评估测试（PETER）组套中。作为此项考量的一部分，研究了重复测试对时间判断可靠性的影响。采用生成法估计八个时间间隔。对19名受试者中的每一位，在连续15个工作日内，每天针对每个时间间隔单独进行五次试验。报告了两个分数，即恒定误差和可变误差。天数对恒定误差的影响不显著，对可变误差的影响适中（p < .04）。标准差在各试验中相对稳定。发现两种误差在重复测试的数天内可靠性均显著下降。得出的结论是，这项时间估计测试不太适合纳入PETER，但鉴于时间估计任务在性能测试组套中可能具有独特贡献，有必要进行进一步研究。
