概括
这项研究发现,有问题的社交媒体使用 (PSMU) 与神经黑色素敏感MRI (NM-MRI) 信号强度在关键大脑区域之间没有显著的联系. 需要进一步的研究来了解PSMU的大脑相关物.
科学领域:
- 神经成像是一种神经成像.
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
背景情况:
- 对神经黑色素敏感的MRI (NM-MRI) 显示出作为多巴胺功能指标的前景.
- 改变的NM-MRI与物质使用障碍有关.
- NM-MRI尚未与有问题的社交媒体使用 (PSMU) 相关研究.
研究的目的:
- 调查PSMU和NM-MRI信号强度在黑体和腹膜区域 (SN-VTA) 之间的关联.
主要方法:
- 72名年轻人完成了贝根社交媒体成量表 (Bergen Social Media Addiction Scale) 的评估.
- 参与者接受了NM-MRI扫描.
- 线性回归分析了NM-MRI信号强度和PSMU得分,控制年龄,性别和精神病家族史.
主要成果:
- 在SN-VTA中,较高的PSMU和平均NM-MRI信号强度之间没有发现显著的关联.
- Voxelwise 分析发现了一些具有更高 NM 信号强度的 voxel,但经过校正后的结果没有统计学意义.

02:10Social Scripts
10.3K
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

02:06Social Exchange Theory

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

01:37Social Loafing

Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...
