该实验测试了双任务对5岁和8岁儿童的时间繁殖的影响。儿童必须重现持续6或12 s的刺激持续时间，在此期间，他们在低（LA）和高（HA）注意力需求条件下执行或未执行同时执行的非时空任务（即图片命名）。结果表明，无论使用什么持续时间值，儿童在双重任务中都比单任务条件复制了较短的持续时间。但是，在5岁的孩子中，这种缩短效果比8岁的孩子更大。此外，在5岁的孩子中，双重任务（LA或HA）的时间复制明显短于单任务中，而在8岁的孩子中，差异仅在HA双重之间达到显着性 - 任务和单个任务。在非阶梯任务中，双重任务中命名误差的比例也比单任务中的比例更高，尤其是在高度注意需求下，但在测试的两个年龄组之间没有显着差异。 （c）2002年Elsevier Science B.V.发表
This experiment tested the effect of a dual-task on time reproduction in 5- and 8-year-olds. Children had to reproduce a stimulus duration lasting for 6 or 12 s, during which they either did or did not perform a concurrent non-temporal task (i.e. picture naming) both in low (LA) and high (HA) attentional demand conditions. The results showed that children reproduced shorter durations in the dual-task than in the single-task condition, whatever the duration value used. However, this shortening effect was greater in the 5-year-olds than in the 8-year-olds. Furthermore, in the 5-year-olds, temporal reproductions were significantly shorter in both dual-tasks (LA or HA) than in the single-task, whereas, in the 8-year-olds, differences reached significance only between the HA dual-task and the single-task. In the non-temporal task, the proportion of naming errors was also greater in the dual-task than in the single-task, especially under high attentional demand, but it did not significantly differ between the two age groups tested.
