ABSTRACT People with aphasia frequently present with nonlinguistic deficits, in addition to their compromised language abilities, which may contribute to their problems with reading comprehension. Treatment of attention, working memory and executive control may improve reading comprehension in individuals with aphasia, particularly those with mild reading problems. This single-case experimental design study evaluated the efficacy of Attention Process Training-3, an intervention combining direct attention training and metacognitive facilitation, for improving reading comprehension in individuals with mild aphasia. A multiple baseline design across six participants was used to evaluate treatment effects. The primary outcome measure was a maze reading task. Cognitive measures were administered pre- and post-treatment. Visual inspection of graphed maze reading performance data indicated a basic effect between APT-3 and improved maze reading for three of the six participants. Quantitative analyses, using Tau-U, corroborated findings identified through visual analysis. The overall effect size was significant (Tau = .48, p = .01). Results suggest that APT-3 has the potential to improve reading in individuals with aphasia, but that it may be more efficacious under certain conditions. Treatment and participant variables, including intensity of treatment and metacognitive strategy usage, are discussed as potential influences on participants’ responsiveness to APT-3.

注意过程训练-3 提高轻度失语症的阅读理解能力：单例实验设计研究

摘要 除了语言能力受损外，失语症患者还经常出现非语言缺陷，这可能会导致他们的阅读理解问题。注意力、工作记忆和执行控制的治疗可能会改善失语症患者的阅读理解能力，尤其是那些有轻度阅读问题的人。这项单例实验设计研究评估了注意力过程训练 3 的功效，这是一种结合直接注意力训练和元认知促进的干预措施，用于提高轻度失语症患者的阅读理解能力。六名参与者的多基线设计用于评估治疗效果。主要结果测量是迷宫阅读任务。在治疗前和治疗后进行认知测量。对图形迷宫阅读性能数据的目视检查表明，对于六名参与者中的三人，APT-3 和改进的迷宫阅读之间存在基本效果。使用 Tau-U 进行的定量分析证实了通过视觉分析确定的发现。总体效应大小显着（Tau = .48，p = .01）。结果表明，APT-3 有可能改善失语症患者的阅读能力，但在某些情况下可能更有效。治疗和参与者变量，包括治疗强度和元认知策略的使用，被讨论为对参与者对 APT-3 反应的潜在影响。通过视觉分析确定的确证结果。总体效应大小显着（Tau = .48，p = .01）。结果表明，APT-3 有可能改善失语症患者的阅读能力，但在某些情况下可能更有效。治疗和参与者变量，包括治疗强度和元认知策略的使用，被讨论为对参与者对 APT-3 反应的潜在影响。通过视觉分析确定的确证结果。总体效应大小显着（Tau = .48，p = .01）。结果表明，APT-3 有可能改善失语症患者的阅读能力，但在某些情况下可能更有效。治疗和参与者变量，包括治疗强度和元认知策略的使用，被讨论为对参与者对 APT-3 反应的潜在影响。
