The aim of the study was to compare approaches highlighting either semantic or phonological features to treat naming deficits in aphasia. Treatment focused on improving picture naming. An alternating treatments design was used with a multiple baseline design across stimuli to examine effects of both approaches in two participants with varying degrees of anomia. The features approaches were modified in that three, rather than six, features were used. Significant differential effects were found across participants; this appeared to be a function of each participant's strengths or preferences over the course of treatment. Modest generalization effects were obtained for one participant. Naming error analyses revealed patterns suggestive of increased lexical access for both participants. These findings provide evidence that using a modified features-based protocol can improve naming when incorporating both semantic and phonological feature cues. Naming error patterns can provide additional evidence of improved naming during treatment.
本研究的目的是比较突出语义或语音特征的方法，以治疗失语症中的命名缺陷。治疗重点在于改善图片命名。采用交替治疗设计，并在刺激物上采用多基线设计，以检验这两种方法对两名不同程度命名障碍患者的效果。对特征方法进行了修改，即使用三个而非六个特征。在不同参与者中发现了显著的差异效应；这似乎是每个参与者在治疗过程中的优势或偏好所致。其中一名参与者获得了适度的泛化效应。命名错误分析揭示了两名参与者词汇通达增加的模式。这些发现提供了证据，表明使用基于特征的改良方案，在纳入语义和语音特征线索时可以改善命名。命名错误模式可以为治疗期间命名改善提供额外证据。
