项目摘要
Project Summary
Aphasia is an impairment in the expression or comprehension of language that results from stroke, traumatic
brain injury or progressive neurological disease. Approximately two million people in the United States suffer
from aphasia, which has profound impacts on quality of life, the ability to return to work and participation in life
activities. Research has shown that speech-language therapy, the treatment for aphasia, can significantly
improve people’s ability to communicate. However, a major limitation in the field of aphasia rehabilitation is the
lack of predictability in patients’ response to therapy and the inability to tailor treatment to individuals. Currently,
aphasia treatments are selected largely based on patient’s language abilities and language deficits with little
consideration of learning ability, which we call learning phenotype. Learning phenotype has been used to inform
rehabilitation approaches in other domains but is not currently considered in aphasia. Our overarching
hypothesis is that poor alignment of learning ability and language therapy limits progress for patients and
presents a barrier to individualizing treatment.
The objectives of the proposed study are to (1) determine the learning phenotype of individuals with aphasia,
and (2) examine how lesion characteristics (size and location of damage to the brain), language ability and
cognitive ability relate to learning ability. To accomplish our objectives, we will measure implicit (observational)
and explicit (rule-based) learning ability in people with aphasia via computer-based tasks. Regression models
will be used to examine brain and behavioral factors that relate to learning ability.
An in-depth characterization of learning in aphasia is important, as research has suggested that multiple
learning systems exist. Furthermore, manipulations to stimuli, task, and feedback can lead to differential
recruitment of learning systems and unlock learning potential, particularly in clinical populations (Ashby et al.,
1998; 2002; 2003; Ashby & O’Brien, 2005; Davis, Love, & Maddox, 2009; Knowlton et al., 1992; Koenig et al.,
2007; Shohamy et al., 2004; Squire & Knowlton, 1995). Our prior work in aphasia supports the hypothesis that
individuals with aphasia suffer from impaired learning mechanisms and are sensitive to task
manipulations(Vallila-Rohter & Kiran, 2013). These findings demonstrate that that PWA are successful learning
in some conditions and not others and provides the rationale for the proposed series of studies focused on
characterizing learning abilities in individuals with aphasia.
The long-term goal of our research is to maximize rehabilitation outcomes for individuals with aphasia by
aligning learning ability with intervention approach.
项目摘要
失语症是一种语言表达或理解障碍,由中风、创伤性
脑损伤或进行性神经系统疾病。 在美国大约有两百万人
失语症对生活质量、重返工作岗位和参与生活的能力有着深远的影响。
活动 研究表明,治疗失语症的言语矫正语言疗法,
提高人们的沟通能力。然而,失语症康复领域的一个主要限制是
患者对治疗的反应缺乏可预测性,并且无法为个人定制治疗。目前,
失语症治疗的选择主要基于患者的语言能力和语言缺陷,
学习能力的考虑,我们称之为学习表型。学习表型已被用来告知
在其他领域的康复方法,但目前没有考虑在失语症。我们的总体
一种假设是,学习能力和语言治疗的不一致限制了患者的进步,
这是个体化治疗的障碍。
这项研究的目的是:(1)确定失语症患者的学习表型,
以及(2)检查病变特征(大脑损伤的大小和位置)、语言能力和
认知能力与学习能力有关。为了实现我们的目标,我们将测量内隐(观察)
和明确的(基于规则的)学习能力在失语症患者通过计算机模拟任务。回归模型
将被用来检查与学习能力有关的大脑和行为因素。
对失语症患者的学习进行深入的表征是很重要的,因为研究表明,
此外,对刺激、任务和反馈的操纵会导致不同的学习系统。
招募学习系统并释放学习潜力,特别是在临床人群中(Ashby等人,
1998; 2002; 2003; Ashby &奥布莱恩,2005; Davis,Love,& Maddox,2009;诺尔顿等人, 1992; Koenig等人,
2007; Shohamy等人, 2004; Squire &诺尔顿,1995)。我们先前在失语症方面的工作支持这样的假设,
失语症患者的学习机制受损,
操作(Vallila-Rohter & Kiran,2013)。这些发现表明,PWA是成功的学习
在某些情况下,而不是其他人,并提供了理由,拟议的一系列研究的重点是
描述了失语症患者的学习能力。
我们研究的长期目标是通过以下方法使失语症患者的康复效果最大化:
将学习能力与干预方法结合起来。
