概括
高社交焦虑 (HSA) 个体表现出认知控制障碍,影响他们对社会威胁的反应. 这影响了注意力偏差,建议新的干预目标.
科学领域:
- 认知心理学
- 临床心理学
- 神经科学
背景情况:
- 在高度社会焦虑 (HSA) 中,认知控制和注意偏差之间的相互作用尚未得到充分理解.
- 现有的研究缺乏综合不同控制机制的综合模型.
- 双重控制机制 (DMC) 框架为研究这些关系提供了一个潜在的镜头.
研究的目的:
- 研究认知控制模式对高度社会焦虑 (HSA) 个体的注意偏差的影响.
- 探索主动和反应性控制如何影响与社会威胁线索的注意力参与和脱离.
- 为了解和治疗社会焦虑症提供精细的理论框架.
主要方法:
- 使用双重控制机制 (DMC) 框架.
- 使用了AX连续性能任务和点探测任务.
- 招募了55名低社会焦虑 (LSA) 和67名高社会焦虑 (HSA) 的人.
主要成果:
- 在主动和反应控制方面,HSA表现出缺陷,以较低的准确性和较低的歧视指数为证据.
- 在HSA中更高的主动控制与更快地脱离威胁线索相关,但只有当主动控制高时.
- 在HSA中更高的反应控制与更强的威胁线索相关,但只有当反应控制高时.
结论:
- 这项研究是第一个在HSA中发现主动和反应性认知控制系统的共同障碍.
- HSA 的注意偏差是由认知控制模式独立调节的,而不仅仅是由焦虑水平驱动的.
- 研究结果表明,针对特定认知控制缺陷的干预措施可以有效地减少社会焦虑的注意偏差.

78
Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
