概括
认知训练,包括工作记忆 (WM) 和视觉搜索 (VS),改善了成年人和没有酒精使用障碍 (AUD) 的执行认知功能 (ECF). 在AUD参与者中,ECF的改善和饮酒减少持续了训练后的一个月.
科学领域:
- 认知神经科学 认知神经科学
- 神经心理学 神经心理学
背景情况:
- 工作记忆 (WM) 训练在增强执行认知功能 (ECF) 的有效性仍在争论中,特别是在远传效应方面.
- 研究正在探索WM培训对现有ECF赤字的临床人群的潜在好处.
研究的目的:
- 研究WM训练与非WM视觉搜索 (VS) 控制训练对ECF在患有酒精使用障碍 (AUD) 和健康对照者的影响.
- 评估训练后延迟折扣,抑制和饮酒行为的改善.
主要方法:
- 参与者 (AUD和非AUD) 在4周内接受了15次适应性WM或VS训练.
- 使用延迟折扣任务,侧边,颜色和空间Stroop任务来测量ECF.
- 在AUD组的饮酒行为也被监控.
主要成果:
- 无论是WM还是VS培训,在4周和1个月的随访中,所有ECF措施都取得了显著的改善.
- 培训减少了所有参与者的延迟折扣率和Stroop/Flanker任务干扰.
- 在训练后一个月,AUD参与者表现出持续减少饮酒行为.
结论:
- 要求认知训练的非特异效应,而不是WM特异效应,可能会推动ECF增强.
- 认知训练的好处,包括改善ECF和减少AUD中的饮酒,在干预后至少保持一个月.

Working Memory
385
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...

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...
