双语失语者 (BiPWA) 的语言混合与语言障碍有关,而不是认知控制问题. 失言症的严重程度和每个语言的熟练程度都会影响混合模式.
科学领域:
- 神经语言学是一种神经语言学.
- 心理语言学 心理语言学
- 认知科学 认知科学
背景情况:
- 语言混合 (LM) 是一种常见的现象,在神经类型双语者和双语失语者 (BiPWA) 中观察到.
- 了解BiPWA中LM的潜在机制对于有针对性的治疗干预至关重要.
研究的目的:
- 调查双语失语者 (BiPWA) 中的语言混合 (LM) 是否主要是由语言障碍或认知控制缺陷驱动的.
- 为了区分语言特异性因素与一般认知能力对LM模式的贡献.
主要方法:
- 评估了20名讲俄语和希伯来语的BiPWA,并根据语迷症的严重程度分类 (严重/中度与中度). 这是轻微的).
- 在L1-俄语和L2-希伯来语的叙事作品中分析了语言混合频率和模式.
- 参与者填写了语言问卷,双语失语测试 (BAT) 和10个认知测试的电池.
主要成果:
- 与轻度失语症患者相比,在严重/中度失语症的BiPWA中观察到较高的LM频率.
- 在L2-希伯来语 (较弱的中风后语言) 中,LM比L1-俄罗斯语更频繁.
- 在LM中注意到了定性差异:L1-俄语叙述中包含L2-希伯来名词,而L2-希伯来叙述中包括L1-俄语话语标记和函数词.
结论:
- 语言因素,包括中风前后的语言能力和与失语相关的语言障碍,显著预测了LM频率.
- 认知能力并没有成为LM频率的重要预测因素.
- 这一发现表明,双人双语语言混合行为主要与语言技能有关,而不是认知控制障碍.
