在两个随后执行的任务中的第二个中的响应可以加速在时间上在前的第一个任务中的相容响应。这种后向串扰效应（BCE）对人类信息处理的阶段模型中的串行处理的假设提出了挑战，因为它们表明第二响应的某些特征必须在发出第一响应之前被表示。这些功能实际上是相关的BCE是一个悬而未决的问题，即使确定这些功能是重要的理解并行和串行响应选择过程中的双任务性能的性质。基于效果的模型的动作控制的动机，我们在三个实验中表明，BCE在相当大的程度上反映了功能的预期动作效果，虽然功能的响应（或响应相关的动觉反馈）似乎也发挥了作用。这些发现表明，行动效果（或行动目标）的代码可以同时激活，而不是连续激活，从而创建BCE。(C)2014爱思唯尔有限公司版权所有。
Responses in the second of two subsequently performed tasks can speed up compatible responses in the temporally preceding first task. Such backward crosstalk effects (BCEs) represent a challenge to the assumption of serial processing in stage models of human information processing, because they indicate that certain features of the second response have to be represented before the first response is emitted. Which of these features are actually relevant for BCEs is an open question, even though identifying these features is important for understanding the nature of parallel and serial response selection processes in dual-task performance. Motivated by effect-based models of action control, we show in three experiments that the BCE to a considerable degree reflects features of intended action effects, although features of the response proper (or response-associated kinesthetic feedback) also seem to play a role. These findings suggest that the codes of action effects (or action goals) can become activated simultaneously rather than serially, thereby creating BCEs. (C) 2014 Elsevier B.V. All rights reserved.
