Cognitive Dissonance01:38

Cognitive Dissonance

32.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

CNS Depressants: Alcohol and Nicotine

180
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Dissociative Disorders01:27

Dissociative Disorders

40
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

161
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

科学领域:

  • 神经科学是一个神经科学.
  • 心理学 心理学 心理学
  • 成研究 研究成研究

背景情况:

  • 插曲式未来思维 (EFT) 显示了改善成和肥胖的决策的希望.
  • 酒精使用障碍 (AUD) 与决策能力受损有关,可能与神经连接的改变有关.

研究的目的:

  • 研究EFT在AUD患者中的急性神经效应.
  • 为了检查EFT如何影响大脑连接和延迟折扣 (DD) 率.

主要方法:

  • 利用了来自试点研究和先前发表的研究的功能性MRI (fMRI) 数据.
  • 员工休息状态和基于任务的fMRI,包括延迟折扣 (DD) 任务.
  • 分析了默认模式网络,突出网络和海马体内的连接性,专注于额头区域和背侧前额叶皮层 (DLPFC).

主要成果:

  • EFT干预导致DD率在统计上得到改善,这是减少成行为的标志.
  • 休息状态的fMRI显示左海马和前极之间的连接性发生了变化,这表明EFT可能会使AUD中的低连接性正常化.
  • 发现突出网络与右背侧前额叶皮质 (R DLPFC) 之间的静止状态连接存在差异,这对DD任务中的决策速度和准确性有影响.

结论:

  • 与AUD中EFT相关的DD的行为改善可能与神经连接模式的变化有关.
  • 像海马体,前极和DLPFC等区域的改变连接性可能代表了EFT增强决策的关键机制.
  • 这些发现支持EFT作为针对AUD和相关疾病的有针对性的干预措施的发展.
