Destination memory, which is socially driven, refers to the ability to remember to whom one has sent information. Our study investigated destination memory in patients with traumatic brain injuries (TBIs). Patients and control participants were invited to tell proverbs (e.g., "the pen is mightier than the sword") to pictures of celebrities (e.g., Barack Obama). Then they were asked to indicate to which celebrity they had previously told the proverbs. Besides the assessment of destination memory, participants performed a binding task in which they were required to associate letters with their corresponding location. Analysis demonstrated less destination memory and binding in patients with TBIs than in controls. In both populations, significant correlations were observed between destination memory and performances on the binding task. These findings demonstrate difficulty in the ability to attribute information to its appropriate destination in TBI patients, perhaps owing to difficulties in binding separate information together to form a coherent representation of an event in memory.
目的记忆是指能够记住向谁发送了信息，它受社会驱动。我们的研究调查了创伤性脑损伤 (TBI) 患者的目的记忆。我们邀请患者和对照组参与者讲述谚语（例如，“笔比剑更有力”），同时将谚语与名人（例如，巴拉克·奥巴马）的图片相关联。然后，他们被要求指出之前向哪位名人讲述过这些谚语。除了评估目的记忆，参与者还进行了一项绑定任务，要求他们将字母与其对应的位置相关联。分析表明，TBI 患者的目的记忆和绑定能力明显低于对照组。在这两个群体中，目的记忆与绑定任务的表现之间均存在显著相关性。这些发现表明 TBI 患者在将信息归因于其适当目的地的能力方面存在困难，这可能是由于将单独的信息结合在一起以形成记忆中事件的连贯表示存在困难。
