目的 掩蔽启动被认为是一种直接针对失语症患者内隐词汇检索过程的方法。本研究旨在调查重复使用掩蔽重复启动以改善失语症失语症患者的图片命名能力。方法对 6 名失语症患者采用单受试者、多基线设计。训练涉及反复接触与蒙面身份素数或假素数配对的图片。为每个参与者连续训练两个语义类别。分析评估了治疗效果、语义类别内和跨语义类别的概括，以及治疗后立即和治疗后 3 个月对更广泛语言技能的影响。结果 6 名参与者中的 4 名在治疗后立即命名受过训练的项目有所改善。在训练中使用蒙面身份素数呈现的项目通常比在训练期间使用蒙面假素数重复呈现的项目的改进更大。语义类别内部和跨语义类别的泛化是有限的。对更广泛的语言技能的概括是不一致的。结论 掩蔽重复启动可能会改善一些因失语症而患有失语症的个体的命名。讨论了这种治疗方法进一步发展的许多方法论和理论见解。
PurposeMasked priming has been suggested as a way to directly target implicit lexical retrieval processes in aphasia. This study was designed to investigate repeated use of masked repetition priming to improve picture naming in individuals with anomia due to aphasia.MethodA single-subject, multiple-baseline design was used across 6 people with aphasia. Training involved repeated exposure to pictures that were paired with masked identity primes or sham primes. Two semantic categories were trained in series for each participant. Analyses assessed treatment effects, generalization within and across semantic categories, and effects on broader language skills, immediately and 3 months after treatment.ResultsFour of the 6 participants improved in naming trained items immediately after treatment. Improvements were generally greater for items that were presented in training with masked identity primes than items that were presented repeatedly during training with masked sham primes. Generalization within and across semantic categories was limited. Generalization to broader language skills was inconsistent.ConclusionMasked repetition priming may improve naming for some individuals with anomia due to aphasia. A number of methodological and theoretical insights into further development of this treatment approach are discussed.
