概括
患有抑郁症的人对情绪刺激的晚期积极潜力 (LPP) 反应减少,这表明情绪参与受损. 这一发现支持了成年人患有抑郁症或有风险的情绪上下文不敏感假设.
科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
- 精神病学是一个精神病学.
背景情况:
- 抑郁症与情绪处理中断有关,但神经机制尚不清楚.
- 晚期积极潜力 (LPP) 衡量注意力和情绪参与,作为抑郁症研究的生物标志物.
- 情感视觉刺激通常用于研究抑郁症中的心理生理反应.
研究的目的:
- 在患有抑郁症状,缓解抑郁症或家族风险的个体中对LPP幅度的研究进行定量合成.
- 为了研究抑郁症中情绪处理变化的神经支柱.
- 检查与抑郁和脆弱性有关的情感视觉刺激对LPP反应.
主要方法:
- 一个预先注册的对23项涉及2190名参与者的研究的元分析.

- 分析LPP对各种情绪和中性视觉刺激的反应.
主要成果:
- 在所有刺激类别中,在患有抑郁症状和风险组的人群中观察到明显减少的LPP幅度.
- 在成年人中,减少LPP是特定于情绪刺激,而不是中性刺激.
- 保持了情感调制,在小组内,对于愉快/不愉快与中性刺激的LPP更大.

The Influence of Affect on Cognition
339
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

Depression: Overview
1.1K
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Long-term Depression
3.5K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

The Influence of Cognition on Affect
261
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...
