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.

Prosopagnosia

153
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

科学领域:

  • 神经学 神经学
  • 语音语言病理学 语言病理学
  • 认知神经科学 认知神经科学

背景情况:

  • 难以找到单词是复发性复发性多发性硬化症 (RRMS) 患者常见但不太了解的症状.
  • 了解词找困难的潜在机制对于开发有效的干预措施至关重要.

研究的目的:

  • 调查RRMS患者声学处理能力受损的假设.
  • 在这个人群中确定语音处理缺陷和词查找困难之间的关系.

主要方法:

  • 五十名RRMS患者被评估为患者报告的词查找困难 (PR-WFD).
  • 目标表现使用韦克斯勒个人成就测试,第四版 (WIAT-4) 测量,包括语音熟练程度 (PP),文字阅读 (WR) 和句子重复 (SR).

主要成果:

  • 在RRMS患者中,Phonemic Proficiency (PP) 评分明显低于规范期望.
  • 患者报告的更糟糕的词查找困难 (PR-WFD) 特别与较低的语音能力 (PP) 绩效有关.
  • 单词阅读 (WR) 和句子重复 (SR) 的表现与规范期望没有显著差异,与PR-WFD无关.

结论:

  • 语音处理在RRMS患者中明显低于预期,并且与难以找到单词有关.
  • 这些发现支持了早期疾病相关的皮质变化影响RRMS声学处理的假设.
  • 这些结果有助于在多发性硬化症中发现单词困难的不断变化的模型.
