熟悉的单词显著增强双语词汇学习. 这种效应对于使用较少的语言中的单词更为强烈,因为它从跨语言连接中获益更多.
科学领域:
- 心理语言学 心理语言学
- 发展心理学 发展心理学
- 认知科学 认知科学
背景情况:
- 双语词汇获取受到各种因素的影响.
- 联名词,即跨语言有共同的词源起源的单词,被假设是为了促进单词学习.
- 以前的研究表明,认知能力有助于双语者,但精确的机制和缓解因素需要进一步研究.
研究的目的:
- 提出和测试一个账户,语言协同激活加速词学习实例积累在双语.
- 根据语言暴露水平,调查语音对词汇获取的益处是否不同.
- 为了确定相应方便性对于较低暴露语言中的单词比较高暴露语言中的单词更大.
主要方法:
- 利用贝叶斯的项目响应理论来建模获取轨迹.
- 分析了366名双语婴儿 (12-32个月) 学习加泰罗尼亚语和西班牙语的数据.
- 在数据集中包括604个加泰罗尼亚语-西班牙语单词翻译.
主要成果:
- 发现较低暴露语言中单词的相关方便性显著更大 (d = .276).
- 观察到较高暴露语言中单词的最小相关方便性 (d = .022).
- 结果支持这样一个假设,即语言协同激活会影响相关效应.
结论:
- 语言协同激活加速了双语词汇的获取,特别是在较少占主导地位的语言中的单词.
- 这项研究提供了证据,证明了双语发育中的认知效应的语言暴露适度.
- 调查结果强调了在检查双语单词学习中同类的作用时考虑语言暴露水平的重要性.

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...
