猪仔按固定间隔（FI）时间表进行奖励。在偶尔的非奖励测试中，他们通常表现出一种休息-跑步-休息的反应模式。在试验中，运行的开始与结束呈正相关，表明试验中（a）时钟速度，（B）启动时钟的延迟，或（c）试验中使用的单一标准时间的差异。如果标准时间存在差异，则运行的开始和结束基于独立标准时间的任务应产生降低的开始-结束相关性。在2个这样的任务中，开始-结束相关性下降到接近零，尽管其他相关性与标准FI任务中发现的相关性相当。这为试验中使用的单一标准时间的试验间差异提供了证据。
Pigeons were rewarded on a fixed-interval (FI) schedule. On occasional unrewarded tests, they usually showed a break-run-break pattern of responding. Across trials, the start of the run correlated positively with the end, suggesting variance across trials in (a) clock speed, (b) the delay to start the clock, or (c) a single criterion time used on a trial. If variance in criterion time exists, then a task in which the start and the end of the run are based on independent criterion times should produce a reduced start-end correlation. In 2 such tasks, the start-end correlation dropped to near zero, although other correlations were comparable to those found in the standard FI task. This provides evidence for variance across trials in a single criterion time used on a trial.
