本研究调查了基于典型性的语义特征分析（SFA）处理对三个层面泛化的影响：未经训练的相关项目、语义/语音处理任务以及全局语言功能的测量。使用单受试者设计和群体层面的分析，27 名失语症患者 (PWA) 接受了基于典型性的 SFA，以改进他们对非典型和/或典型范例的命名。每周测量经过培训、未培训和监控项目的进展情况。进行治疗前和治疗后评估以评估语义/语音处理和整体语言能力。十个 PWA 作为对照。对于治疗参与者来说，随着时间的推移，准确命名训练项目的可能性明显高于监控项目。当训练非典型项目的特征时，随着时间的推移，准确命名未经训练的典型项目的可能性明显高于未经训练的非典型项目。治疗后在语义/语音处理任务和标准化评估方面观察到显着的进步。在治疗反应组中观察到不同的近端和远端转移模式。还对响应者和对照组之间的表现进行了比较。与对照组相比，应答者在语义处理任务上表现出显着的改善，但组间没有发现其他显着的变化分数差异。除了积极的治疗效果之外，基于典型性的 SFA 命名疗法还导致了多个层面的泛化。
This study investigated the effects of typicality-based semantic feature analysis (SFA) treatment on generalization across three levels: untrained related items, semantic/phonological processing tasks, and measures of global language function. Using a single-subject design with group-level analyses, 27 persons with aphasia (PWA) received typicality-based SFA to improve their naming of atypical and/or typical exemplars. Progress on trained, untrained, and monitored items was measured weekly. Pre- and post-treatment assessments were administered to evaluate semantic/phonological processing and overall language ability. Ten PWA served as controls. For the treatment participants, the likelihood of naming trained items accurately was significantly higher than for monitored items over time. When features of atypical items were trained, the likelihood of naming untrained typical items accurately was significantly higher than for untrained atypical items over time. Significant gains were observed on semantic/phonological processing tasks and standardized assessments after therapy. Different patterns of near and far transfer were seen across treatment response groups. Performance was also compared between responders and controls. Responders demonstrated significantly more improvement on a semantic processing task than controls, but no other significant change score differences were found between groups. In addition to positive treatment effects, typicality-based SFA naming therapy resulted in generalization across multiple levels.
