概括

此摘要是机器生成的。

任务准备和执行都会影响认知任务交换成本. 准备一个任务而没有执行它会产生转换成本,实际执行会在随后的任务中进一步增加这些成本.

科学领域:

认知心理学认知心理学
神经科学是一个神经科学.

背景情况:

即使在准备任务而不执行任务后,也会观察到任务交换成本.
任务准备与执行对转换成本的确切贡献仍然不清楚.

研究的目的:

区分任务准备和任务执行对后续交换成本的影响.
调查转换成本是否反映了对准备或绩效的影响.

主要方法:

采用双重注册程序,涉及只有预警和已完成的试验.
参与者对任务提示和目标刺激都有反应.

主要成果:

在两种试验类型的暗示反应后,暗示交换成本都出现了.
在两种试验类型之后,目标响应的任务交换成本都出现了.
完成试验后,任务交换成本比仅使用提示的试验更高.

结论:

任务准备本身就会影响后续任务的执行.
任务执行增加了超出准备的交换成本.
准备和执行都对观察到的任务交换成本有所贡献.
