人类大脑中的并行处理受到严重的注意力限制，但目前还不清楚这种限制是来自单个注意力过程还是多个不同的注意力过程。我们提供了新的证据，两个候选人，输入注意和中央注意，在不同的时间处理阶段。这一结论是支持计时分析表明，相同的参考阶段（字母识别）后，在输入注意操作的阶段，但在中央注意操作的阶段之前。注意在不同的时间位点运作的发现为不同的注意过程的存在提供了新的支持。
Parallel processing in the human brain is subject to severe attentional limits, but it is unclear whether such limits arise from a single attentional process or multiple distinct attentional processes. We provide new evidence that two candidates, input attention and central attention, operate at different temporal stages of processing. This conclusion is supported by chronometric analyses showing that the same reference stage (letter identification) operates after the stage at which input attention operates, but prior to the stage at which central attention operates. The finding that attention operates at different temporal loci provides new support for the existence of distinct attentional processes.
