Interlocutors engage in acts of conversational repair to resolve trouble sources, or communication breakdowns. This is necessary for successful communication, allowing interlocutors to establish and maintain common ground. Here, we investigated the use of conversational repairs in the conversations of people with Parkinson's disease (PD) and concomitant dysarthria.
Conversational repairs were coded in a large corpus of 114 conversations involving a person with PD and a neurotypical (NT) partner (NT-PD dyads) and a comparison corpus of 80 conversations involving two NT partners (NT-NT dyads). Conversations varied across two contextual dimensions: conversational goal (informational vs. relational) and partner familiarity (familiar vs. unfamiliar).
Over the course of 10-min conversations, NT-PD and NT-NT dyads produced a similar number of conversational repairs; however, NT-PD dyads exhibited higher usage of repairs per conversational turn. In addition, dyads involving participants with PD with moderate dysarthria showed different repair patterns relative to dyads involving participants with PD with mild or mild-moderate dysarthria as well as NT-NT dyads-the key being that they used fewer self-initiated and more other-initiated repairs. Across all dyads, informational conversations had more repairs than relational conversations, and dyads involving participants with PD with moderate dysarthria relied more heavily on other-initiated repairs when conversing with a familiar partner relative to an unfamiliar partner.
The use of repairs in the conversations of people with PD differs from that in NT-NT conversations. The key is that the conversations of people with PD have a greater number of repairs per conversational turn and the distribution of repairs differs when people with PD have more pronounced intelligibility impairments. Additionally, the study provides empirical support for longstanding claims regarding the use of repairs in NT-NT dyads as well as claims from case study conversations involving people with dysarthria.
对话者进行会话修正行为以解决问题源或沟通障碍。这对于成功沟通是必要的，能让对话者建立并维持共同基础。在此，我们研究了帕金森病（PD）合并构音障碍患者对话中的会话修正使用情况。
在一个包含114段涉及PD患者与神经典型（NT）伙伴（NT - PD二元组）对话的大型语料库以及一个包含80段涉及两个NT伙伴（NT - NT二元组）对话的比较语料库中对会话修正进行编码。对话在两个情境维度上有所不同：对话目标（信息性与关系性）和伙伴熟悉程度（熟悉与不熟悉）。
在10分钟的对话过程中，NT - PD二元组和NT - NT二元组产生的会话修正数量相似；然而，NT - PD二元组在每个对话轮次中修正的使用频率更高。此外，与涉及轻度或轻度 - 中度构音障碍的PD患者二元组以及NT - NT二元组相比，涉及中度构音障碍的PD患者二元组表现出不同的修正模式——关键在于他们较少使用自我发起的修正，而更多使用他人发起的修正。在所有二元组中，信息性对话比关系性对话有更多的修正，并且与不熟悉的伙伴交谈时，涉及中度构音障碍的PD患者二元组在与熟悉伙伴交谈时更依赖他人发起的修正。
PD患者对话中修正的使用与NT - NT对话不同。关键在于PD患者的对话在每个对话轮次中有更多的修正，并且当PD患者有更明显的可懂度损害时，修正的分布有所不同。此外，该研究为关于NT - NT二元组中修正使用的长期说法以及涉及构音障碍患者的案例研究对话中的说法提供了实证支持。
