概括
任务切换成本可能不反映认知控制,当有限的刺激鼓励回忆检索时. 使用较少刺激的参与者显示成本降低,这表明他们依赖于学习的关联,而不是加强任务集控制.
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:
- 任务交换成本通常表明认知控制的效率.
- 有限的目标刺激可以促进复合检索,绕过基于规则的任务集控制.
- 在明确规则指令下,复合检索对任务切换成本的影响尚不清楚.
研究的目的:
- 调查复合检索如何影响任务交换成本,当参与者被指示使用任务规则时.
- 检查有限的目标刺激对任务交换训练效应的影响.
主要方法:
- 通过复合和提示目标间隔设计进行了三项实验.
- 参与者被分配到四个目标,八个目标或无限目标组,以操纵复合物检索可行性.
- 测量了任务交换成本和响应一致性效应.
主要成果:
- 四个目标组和八个目标组的参与者显示,与无限目标组相比,任务交换成本的降低更大.
- 在有限的目标群体中观察到更大的响应一致性效应.
- 这些发现在两个实验设计中都是一致的.
结论:
- 用有限的刺激来切换任务成本的降低可能源于刺激-反应关联,而不是改进的认知控制.
- 在有限刺激范式中的任务切换成本可能不准确地代表潜在的认知控制能力.
- 使用任务规则的明确指示并不妨碍采用复合检索策略.

Retrieval
174
Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

Working Memory
448
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...
