概括
工作记忆 (WM) 的神经标记预测了老年人的认知表现,但不是情绪调节. 个人在WM表现上的差异,而不是神经网络,影响了情绪调节策略的使用.
科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
- 老年学是指老年学的学科.
背景情况:
- 年长的成年人往往表现出由于适应性情绪调节而改善的情感福祉.
- 然而,一些老年人使用不适应的策略,影响情绪健康.
- 工作记忆 (WM) 和它的神经基础是与年龄相关的情绪调节变化的关键调节者.
研究的目的:
- 调查全脑工作记忆 (WM) 网络是否可以预测WM表现和情绪调节策略在健康的老年人中使用.
- 为了确定WM的神经标记是否可以概括来预测基于情绪的行为.
- 探索个人差异在WM表现和神经完整性在情绪调节中的作用.
主要方法:
- 通过基于连接体的预测建模,利用来自年轻成年人的全脑WM网络.
- 应用这些网络来预测WM准确性和接受策略在110名健康老年人的样本中使用.
- 分析了基于随机对照试验的基线评估数据,重点关注健康衰老.
主要成果:
- WM网络成功预测了老年人的WM准确性.
- 然而,WM网络并没有预测接受策略的使用或情绪调节中的困难.

Working Memory
386
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...

Cognitive Theories: Lazarus Mediational Theory of Emotion
977
Richard Lazarus' cognitive mediational theory highlights the pivotal role of cognitive appraisal in shaping emotional responses. According to this theory, the evaluation of a stimulus — based on personal values, goals, beliefs, and expectations — mediates the emotional response. This appraisal process is immediate and often occurs unconsciously, influencing the intensity and nature of the resulting emotion.

Cognitive Theories: Schachter-Singer Theory of Emotion
478
Stanley Schachter and Jerome Singer proposed the two-factor theory of emotion, which emphasizes the interplay between physiological arousal and cognitive labeling in forming emotional experiences. This theory suggests that emotions are not simply a result of physiological responses but rather a combination of these responses and the individual's cognitive interpretation of them.

Physiology of Emotion
996
The physiology of emotions is a multifaceted process involving the autonomic nervous system, brain structures, hormones, and neurotransmitters. This intricate interplay dictates how emotions manifest in the body and influence behavior.
Autonomic Nervous System
The autonomic nervous system (ANS) plays a critical role in emotional responses by regulating involuntary physiological functions. It consists of two main components: the sympathetic and parasympathetic systems. The sympathetic system...

Role of Cerebellum and Prefrontal Cortex in Memory
499
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...

Physiological Theories: Cannon-Bard Theory of Emotion
642
The Cannon-Bard theory of emotion, proposed by Walter Cannon and Philip Bard, challenges the notion that emotions are solely the result of physiological responses. Instead, this theory suggests that emotional experiences and physiological arousal occur simultaneously but operate through independent mechanisms. This dual response is initiated by the brain, specifically by the thalamus, which plays a critical role in processing sensory information.
