Language Development

341
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 Cognition01:27

Language and Cognition

342
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.

Information Processing Approach01:30

Information Processing Approach

33
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Higher Mental Functions of the Brain: Language

793
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...

Perceiving Loudness, Pitch, and Location01:21

Perceiving Loudness, Pitch, and Location

205
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

Learning Disabilities01:25

Learning Disabilities

98
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.

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
  • 语音和听力科学 语言和听力科学

背景情况:

  • 审计处理和程序学习缺陷与语言学习困难有关.
  • 迟说话,或早期语言发展缓慢,是持续语言问题的风险因素,原因不明.

研究的目的:

  • 调查听觉处理,程序学习和学龄语言能力之间的关系.
  • 通过听觉事件相关潜力 (ERP) 检查有或没有迟谈史的儿童之间的这些关系.

主要方法:

  • 使用一种被动的听觉事件相关潜力 (ERP) 范式,对60名学龄儿童 (30名有迟谈话史) 进行了研究.
  • 通过在不同噪声条件下 (感知负载) 测量ERP来评估听觉处理.
  • 试图通过操纵刺激可预测性来测量过程性学习,尽管这证明具有挑战性.

主要成果:

  • 在这两组中,噪音对ERP的影响与学龄语言能力无关.
  • 程序式学习模式没有产生可解释的结果.
  • 更好的语言能力与较弱的早期ERP反应 (75-175 ms) 和较强的后期反应 (150-250 ms) 有关.

结论:

  • 这些发现表明,有效的早期听觉处理,反映在较弱的初始ERP中,支持在具有更好的语言技能的儿童中更深入地处理复杂的听觉信息.
  • 这些ERP差异可能表明与语言能力相关的大脑成熟度的变化.
  • 需要进一步的研究,以充分了解程序式学习的作用,并完善听觉处理评估.
