该初步病例系列研究了生物反馈干预对在改良挑战点框架内提供的剩余视轴旋转错误的影响。在挑战点框架中，练习难度被自适应地调整，以增强泛化学习。本研究更具体地评估了使用自定义开源软件挑战点程序（CPP）以计算机为媒介实施挑战点治疗的可行性。参与者是5名母语为英语的人，年龄为7岁;3-15岁;5岁，在以前的治疗中已经建立但没有普遍正确的rhotic生产;总体治疗时间是灵活的。治疗包括电腭描记或视觉-听觉生物反馈，并通过使用CPP软件实施的挑战点原则进行结构化。参与者在获得的泛化增益的大小上存在很大差异。然而，中位总体效应量为4.24，表明参与者在治疗中的反应往往超过被认为具有临床意义的最小值。这些研究结果提供了初步的证据，计算机介导的实施的挑战点框架可以有效地在一些参与者产生概括。
This preliminary case series investigated the effects of biofeedback intervention for residual rhotic errors delivered within a modified challenge point framework. In the challenge point framework, practice difficulty is adaptively adjusted with the goal of enhancing generalization learning. This study more specifically evaluated the feasibility of a computer-mediated implementation of challenge point treatment for rhotic errors using a custom open-source software, the Challenge Point Program (CPP). Participants were five native English speakers, ages 7;3–15;5, who had established but not generalized correct rhotic production in previous treatment; overall treatment duration was flexible. Treatment incorporated either electropalatographic or visual-acoustic biofeedback and was structured by challenge point principles implemented using the CPP software. Participants were highly variable in the magnitude of generalization gains attained. However, the median overall effect size was 4.24, suggesting that participants’ response in treatment tended to exceed the minimum value considered clinically significant. These findings provide preliminary evidence that computer-mediated implementation of the challenge point framework can be effective in producing generalization in some participants.
