Four rats and four pigeons were monitored while performing retrospective timing tasks. All animals displayed collateral behaviors which could have mediated their temporal judgements. Statistical analysis made a good case for such mediation in the case of two pigeons performing on a spatially-differentiated response, but not for the two responding on a color-differentiated response. For the rats, all of which performed on a spatially-differentiated task, prediction of their temporal judgements was always better if based on collateral activity than if based on the passage of time.
在四只大鼠和四只鸽子执行回顾性计时任务时对它们进行了监测。所有动物都表现出可能介导其时间判断的附带行为。对于两只在空间上有差异的反应任务中表现的鸽子，统计分析有力地证明了这种介导作用，但对于两只在颜色上有差异的反应任务中表现的鸽子则不然。对于所有在空间上有差异的任务中表现的大鼠，基于附带活动对其时间判断的预测总是比基于时间流逝的预测更好。
