概括
患有发育性语言障碍 (DLD) 的儿童在从负面反中学习时,与通常发育的同龄人相比,显示出不同的大脑连接模式. 这表明独特的神经策略可能用于认知控制和DLD错误监测.
科学领域:
- 神经科学是一个神经科学.
- 发展心理学 发展心理学
- 认知科学 认知科学
背景情况:
- 患有发育性语言障碍 (DLD) 的儿童经常难以处理反,影响学习和执行功能.
- 有效的反处理对于目标导向行为至关重要,并依赖于认知控制机制.
研究的目的:
- 研究DLD学龄儿童与典型发育 (TD) 同龄人之间的反处理的神经基础.
- 检查中额头的达频段振荡作为认知控制和反处理期间错误监测的指标.
主要方法:
- 使用脑电图 (EEG) 测量中额头甲间试验连贯性 (ITC) 和间位点连贯性 (ISC) 在患有和没有DLD的儿童中 (n=33,年龄为8-13).
- 使用威斯康星卡排序测试 (WCST) 在特定时间窗口内引起反反应 (FRN为200-400毫秒,P3a为400-600毫秒).
主要成果:
- 这两组在负面反后表现出增强的中额头太振荡,导致行为改善 (FRN窗口).
- 观察到不同位点间连贯性 (ISC) 的明显模式:TD儿童显示中额头右感觉运动连接,而DLD儿童显示中额头左感觉运动连接以有效处理负反.
- P3a窗口激活仅在TD组中存在.
结论:
- 患有DLD的儿童可以利用替代或补偿的神经通路来处理负面反.
- 不典型的连接模式,可能涉及左侧感觉运动区域,可能是DLD的这些差异的基础.
- 这些发现突出了DLD认知控制和学习的独特神经机制.

Higher Mental Functions of the Brain: Language
6.0K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Effects of feedback
1.1K
Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Feedback control systems
798
Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

Language Development
1.1K
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Language and Cognition
874
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Learning Disabilities
696
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
