概括
互联网游戏障碍 (IGD) 与增加的反应性攻击性 (RA) 有关. 脑部成像显示了右背带皮质灰质体积的变化,脊带皮质介导了这种关系,为干预提供了潜在的生物标志物.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 神经成像是一种神经成像.
背景情况:
- 互联网游戏障碍 (IGD) 与反应性攻击性 (RA) 有正相关.
- 将过度在线游戏与侵略联系起来的神经机制仍然不清楚.
- 这项研究调查了RA在IGD的年轻成年人的神经生物学基础.
研究的目的:
- 探索互联网游戏障碍的年轻成年人反应性侵略的神经生物学基础.
- 为了确定IGD和RA的潜在神经风险生物标志物.
主要方法:
- 与84名年轻成年人 (23名IGD,24名有风险,37名对照) 进行的病例控制研究.
- 用T1加权的MRI和基于voxel的形态测量 (VBM) 来评估灰质体积 (GMV) 的变化.
- 部分相关性和调解分析检查了GMV变化,IGD严重程度和RA得分.
主要成果:
- 在IGD组中,中额前 (MFG) 的GMV增加,右背带皮层 (DCG) 的GMV降低.
- 风险组在左侧MFG中表现出增加的GMV.
- 减少的右DCG GMV与RA得分有负相关性,并显著调解了IGD-RA关系 (22.8%的效果大小).
结论:
- 结果表明,在正确的DCG中,特定的GMV变化是IGD的潜在早期风险生物标志物.
- 这项研究增强了对连接RA和IGD的神经生物学机制的理解.
- 已识别的机制可能有助于针对IGD和相关的侵略性进行有针对性的治疗干预.

01:47Aggression
27.7K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

01:21Secondary Motives: Affiliation Motivation and Aggression Motivation
301
Affiliation motivation is the intrinsic desire to connect with others and belong to a social group, which plays a crucial role in forming and maintaining personal relationships. This type of motivation is essential for psychological well-being, as it provides individuals with a sense of community and support. An example of this is a student who joins a study group in order to feel a sense of connection. People with high affiliation motivation actively seek social approval, take satisfaction in...

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

01:28Conduct Disorder
27
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Antisocial personality disorder is a chronic mental health condition characterized by persistent patterns of disregard for the rights and well-being of others. Individuals with antisocial personality disorder exhibit behaviors that include deceitfulness, impulsivity, irresponsibility, aggression, and a profound lack of empathy. These traits often manifest early in life and persist into adulthood, leading to significant personal, social, and legal consequences.
