Abstract:
The exploration of naming error patterns in aphasia provides insights into the cognitive processes underlying naming performance. We investigated how semantic and phonological abilities correlate and how they influence naming performance in aphasia. Data from 296 individuals with aphasia, drawn from the Moss Aphasia Psycholinguistics Project Database, were analyzed using a structural equation model. The model incorporated latent variables for semantics and phonology and manifest variables for naming accuracy and error patterns. There was a moderate positive correlation between semantics and phonology after controlling for overall aphasia severity. Both semantic and phonological abilities influenced naming accuracy. Semantic abilities negatively related to semantic, mixed, unrelated errors, and no responses. Interestingly, phonology positively affected semantic errors. Additionally, phonological abilities negatively related to each of phonological and neologism errors. These results highlight the role of semantic and phonological skills on naming performance in aphasia and reveal a relationship between these cognitive processes.
摘要:
对失语症中命名错误模式的探索提供了对命名性能基础的认知过程的见解。我们调查了语义和语音能力如何相关,以及它们如何影响失语症中的命名表现。数据来自296名失语症患者,来自莫斯失语症心理语言学项目数据库,使用结构方程模型进行了分析。该模型结合了语义和语音的潜在变量以及用于命名准确性和错误模式的清单变量。在控制总体失语症严重程度后,语义和语音之间存在中度正相关。语义和语音能力都会影响命名准确性。语义能力与语义负相关,混合,无关的错误,没有回应。有趣的是,语音对语义错误有积极影响。此外,语音能力与每个语音和新词错误都呈负相关。这些结果强调了语义和语音技能在失语症中命名表现中的作用,并揭示了这些认知过程之间的关系。
