从四名失语症患者和四名神经正常的西班牙裔双语者中获取单语英语、单语西班牙语和双语环境中的会话话语样本，以识别语码转换模式。基于矩阵语言框架（MLF）模型（Myers-Scotton，1993a）的样本分析揭示了失语症和正常受试者的语言上下文的一致匹配。失语症受试者表现出更高频率的 MLF 成分和语码转换模式，而这在正常受试者的语音样本中并不明显。结果表明，神经损伤后对两种语言进行交流的依赖性增加。
Conversational discourse samples were obtained from four aphasic and four neurologically normal Hispanic bilinguals in monolingual English, monolingual Spanish, and bilingual contexts to identify codeswitching patterns. Analysis of the samples based on the Matrix Language Frame (MLF) Model (Myers-Scotton, 1993a) revealed consistent matching of the language context by the aphasic and normal subjects. The aphasic subjects demonstrated a greater frequency of MLF constituents and codeswitching patterns not evident in the speech samples of the normal subjects. Results suggest an increased dependence on both languages for communication following neurological impairment.
