Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

68
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.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

High-Level and Low-Level Awareness

273
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

概括

积极抑制不相关的视觉信息不需要注意力资源,即使在双重任务. 这项研究发现,当注意力在任务之间被分割时,这种隐性抑制能力保持不变.

  • 视觉感知 视觉感知 视觉感知
  • 注意力研究研究研究研究

背景情况:

  • 讨论了注意力资源在抑制不相关的视觉特征中的作用.
  • 之前的研究表明,当认知负载高时,抑制是不可用的.

研究的目的:

  • 调查主动抑制视觉干扰器是否需要在双重任务期间注意力资源.
  • 提供行为证据支持或反驳抑制的资源依赖.

主要方法:

  • 参与者执行了一项快速串行视觉演示 (RSVP) 任务,随后执行了一个视觉搜索任务.
  • 捕捉探头范式评估了不同滞后 (Lag 2和Lag 8) 的分心视觉特征的抑制.

主要成果:

  • 预先抑制,以分散器位置的探头召回减少为标志,在 Lag 2 和 Lag 8 两处都观察到.
  • 抑制的有效性在两个滞后之间没有显著差异,这表明在双重任务期间的抑制是完整的.

结论:

  • 积极的视觉抑制是一种隐含的过程,不会耗尽注意力资源.
  • 反应性抑制可能需要注意力资源,但主动性抑制独立运作.
