Language and Cognition

367
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

60
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...

  • 神经科学是一个神经科学.
  • 计算生物学 计算生物学

背景情况:

  • 全球发育迟缓 (GDD) 呈现出显著的基因型和表型异质性,复杂化了针对性干预措施的开发.
  • 对GDD个体遗传原因的稀有性阻碍了传统的临床试验设计.
  • 在瘤学中成功的篮子试验为GDD研究提供了潜在的模型,但需要有效的患者分层.

研究的目的:

  • 评估聚合和分裂集群方法对GDD个体分层的有用性.
  • 识别潜在的患者子组,他们可以接受新的治疗策略,如篮子试验.
  • 探索GDD中表型集群和潜在的遗传网络之间的关系.

主要方法:
