This conversation analytic study investigates how couples manage conflicting knowledge claims when one of the persons has dementia (PWD). The data are video-recordings of 16 couples talking with a third party. The analysis focuses on the negotiation of epistemic rights, more precisely how partners initiate repair and correct claims made by the PWD on matters belonging to the latter’s epistemic domain. We identified three main practices for correcting the PWD: (1) correcting the statement, thereby claiming epistemic authority for oneself and denying it to the PWD, (2) inviting the PWD to self-correct, thereby attributing some epistemic authority to the PWD, and (3) disagreeing and providing reasons for one’s alternative claim, establishing a more symmetric epistemic gradient. The PWDs responses to the corrections displayed different degrees of acceptance, ranging from self-denigration to resistance and insistence.

这项对话分析研究调查了其中一个人患有痴呆症（PWD）时，夫妻如何处理相互矛盾的知识主张。数据是与第三方交谈的16对夫妇的视频记录。分析的重点是对认知权的谈判，更确切地说是合作伙伴如何启动和纠正PWD对属于其认知领域的事项提出的主张。我们确定了三种纠正PWD的主要做法：（1）更正该陈述，从而要求自己具有认知权威，并拒绝PWD，（2）邀请PWD进行自我纠正，从而将某些认知权威归因于PWD， （3）不同意并提出理由，建立一个更加对称的认知梯度。
