Children from 5 to 8 years of age, as well as adults, performed a temporal reproduction task in both a solo-timing condition and a multi-timing condition, with different durations presented simultaneously. In the multi-timing condition, all durations were processed because the participants did not know in advance which stimulus needed to be judged. In a first experiment, two or three durations were presented with a synchrony of their onset. In a second experiment, two durations were presented simultaneously with asynchrony of their offset, different lengths of the concurrent duration, and different presentation orders. In addition, the participants’ cognitive abilities in terms of selective attention, as well as short-term and working memory, were assessed with different neuropsychological tests. The results of both experiments showed that children and adults alike were able to process multiple durations simultaneously. However, the simultaneous presentation of different durations generated a temporal interference effect in children and adults, resulting in longer and more variable time estimates. This temporal interference effect was nevertheless higher in children due to their limited attention capacities. Therefore, a developmental improvement in the ability to process different durations simultaneously is related to the cognitive development of attention capacities.

5 至 8 岁的儿童以及成人在单独时间条件和多时间条件下执行时间再现任务，同时呈现不同的持续时间。在多时间条件下，所有的持续时间都被处理，因为参与者事先不知道需要判断哪个刺激。在第一个实验中，两个或三个持续时间与它们的开始同步。在第二个实验中，两个持续时间同时呈现，它们的偏移量不同步，同时持续时间的长度不同，呈现顺序也不同。此外，参与者在选择性注意以及短期和工作记忆方面的认知能力通过不同的神经心理学测试进行评估。两个实验的结果都表明，儿童和成人都能够同时处理多个持续时间。然而，不同持续时间的同时呈现在儿童和成人中产生了时间干扰效应，导致时间估计更长且更可变。然而，由于儿童的注意力有限，这种时间干扰效应在儿童中更高。因此，同时处理不同持续时间的能力的发展提高与注意力能力的认知发展有关。然而，由于儿童的注意力有限，这种时间干扰效应在儿童中更高。因此，同时处理不同持续时间的能力的发展提高与注意力能力的认知发展有关。然而，由于儿童的注意力有限，这种时间干扰效应在儿童中更高。因此，同时处理不同持续时间的能力的发展提高与注意力能力的认知发展有关。
