概括

考试焦虑通过减少注意力控制来破坏工作记忆. 与低测试焦虑 (LTA) 个体相比,高测试焦虑 (HTA) 个体在记忆编码过程中表现出较少的theta活动.

科学领域:

认知神经科学认知神经科学
教育心理学教育心理学

背景情况:

考试焦虑通常影响学生,通过注意力资源耗尽损害工作记忆.
将考试焦虑与工作记忆缺陷联系在一起的特定神经机制尚未完全理解.

研究的目的:

研究测试焦虑如何影响工作记忆中的神经振荡.
为了检查不同认知负载对这些神经模式的影响.

主要方法:

使用脑电图 (EEG) 来记录大脑活动.
参与者完成了斯特恩伯格工作记忆任务,认知负载为2,4和8个字母.
对高测试焦虑 (HTA) 和低测试焦虑 (LTA) 组进行了比较.

主要成果:

在中等认知负载 (4个字母) 下,HTA个体表现出降低了自上而下的注意力控制,编码过程中theta活动减少的证据.
LTA个体表现出增加的theta活动,认知负载高达4个字母,然后平稳.
HTA个体在认知负载之间没有显著的甲基活性调制.

结论:

考试焦虑会损害工作记忆的编码,特别是在适度的认知负载下,由于注意力控制不足.
在工作记忆编码过程中,认知负载和太带活动之间的关系是由个体的测试焦虑水平调节的.

Working Memory

Working Memory

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...
