项目摘要
DESCRIPTION (provided by applicant): Cognitive Factors Underlying Social Communication of Adults with Traumatic Brain Injury Each year approximately 125,000 Americans will sustain a traumatic brain injury (TBI) from which they are expected to suffer lifelong disability [2]. Of the
myriad effects associated with moderate-to-severe TBI, social outcomes are among the most penalizing and can include the loss of friendships and social isolation [3]. Research has shown that social communication problems contribute significantly to these negative social outcomes [4] and are therefore important rehabilitation targets [5]. Despite the severe consequences of social communication impairments, the underlying mechanisms of these deficits remain poorly understood. Research has linked social communication impairments in adults with TBI to two cognitive processes that are frequently impaired in this population: theory of mind (ToM) and executive functioning (EF) [6-9]. Despite evidence of a likely association between these processes, it is unclear whether these relationships are correlational or causal in nature. The proposed study will investigate both the underlying cognitive mechanisms and social consequences of social communication problems for adults with TBI with three specific aims. The first aim of the proposed study is to investigate the effect of ToM demand on social communication performance of adults with TBI. It is predicted that adults with TBI will fail to increase the frequency with which they use words that reflect ToM (i.e. mental state terms) from a low-ToM discourse condition to a high-ToM discourse condition relative to comparison participants (CPs). The second aim of the proposed research is to investigate the effect of EF demand on social communication performance of adults with TBI. It is hypothesized that the frequency of social communication errors committed by adults with TBI will be greater in a high-EF condition relative to in a low-EF condition. EF demand is expected to have a significantly greater effect for adults with TBI. The third aim of the proposed study is to determine the relationship between social communication problems in adults with TBI and how their discourse is judged by naive raters. It is predicted that the degree of increase in mental state terms from the low- to high-ToM condition will be positively associated with naive raters' judgments while it is expected that the change in frequency of social communication errors from the low- to high-EF condition will be inversely associated with naive raters' judgments of social acceptability and appropriateness in adults with TBI. The proposed research will provide important information regarding the underlying cognitive mechanisms of social communication impairments of adults with TBI as well as the real-world consequences of these impairments. Findings of this study have a strong potential to inform future treatment of social communication impairments in adults with TBI.
PUBLIC HEALTH RELEVANCE: Following moderate-to-severe traumatic brain injury (TBI) individuals frequently experience many negative social outcomes that have been associated with poor social communication. The proposed research will investigate how cognitive processing demands affect social communication in adults with TBI with the long-term goal of using this gained knowledge to help direct the development of more effective treatments for social communication impairments of adults with TBI.
描述(由申请人提供):创伤性脑损伤成年人社会交往的认知因素每年约有125,000名美国人将遭受创伤性脑损伤(TBI),预计他们将遭受终身残疾[2]。的
与中度至重度TBI相关的无数影响中,社会后果是最不利的,可能包括失去友谊和社会孤立[3]。研究表明,社会沟通问题对这些负面的社会结果有很大的影响[4],因此是重要的康复目标[5]。尽管社会沟通障碍的严重后果,这些赤字的根本机制仍然知之甚少。研究将TBI成人的社交障碍与这一人群中经常受损的两个认知过程联系起来:心理理论(ToM)和执行功能(EF)[6-9]。尽管有证据表明这些过程之间可能存在关联,但尚不清楚这些关系在本质上是相互关联还是因果关系。拟议的研究将探讨潜在的认知机制和社会后果的社会沟通问题的成年人与TBI有三个具体的目标。本研究的第一个目的是探讨心理理论需求对成人创伤性脑损伤患者社会沟通表现的影响。据预测,成年人TBI将无法增加的频率,他们使用的话,反映心理理论(即心理状态方面)从一个低的心理理论话语条件,以一个高的心理理论话语条件相对于比较参与者(CP)。本研究的第二个目的是探讨执行功能需求对成人创伤性脑损伤患者社会沟通表现的影响。据推测,与TBI的成年人所犯的社会沟通错误的频率将在高EF条件下,相对于在低EF条件下更大。预计EF需求对TBI成人的影响更大。本研究的第三个目的是确定TBI成人的社会沟通问题与他们的话语如何被天真的评分者判断之间的关系。据预测,从低到高的心理理论条件的心理状态方面的增加程度将与天真的评分者的判断呈正相关,而预计从低到高的EF条件的社会沟通错误的频率的变化将与天真的评分者的判断呈负相关的社会接受性和适当的TBI成人。 拟议的研究将提供有关TBI成人社交障碍的潜在认知机制以及这些障碍的现实后果的重要信息。这项研究的结果有很大的潜力,为未来治疗TBI成年人的社会沟通障碍提供信息。
公共卫生相关性:在中度至重度创伤性脑损伤(TBI)后,个体经常会经历许多与不良社会沟通相关的负面社会后果。拟议的研究将调查认知处理需求如何影响TBI成年人的社会沟通,长期目标是利用这些获得的知识来帮助指导TBI成年人社会沟通障碍的更有效治疗方法的发展。
