DESCRIPTION (provided by applicant): The goal of this proposal is to examine whether age-related cognitive decline impairs older adults' ability to regulate negative bias against stigmatized individuals. It has been widely demonstrated that aging has a deleterious impact on cognition (specifically memory and executive function), but the extent and cause of these impairments is widely debated. This proposal thus uses social neuroscience techniques as an alternative approach to investigate the effects of aging on cognition. Extensive research has demonstrated that executive function plays a central role in regulating bias against stigma. Thus, this proposal will examine the effects of aging on the underlying neural mechanisms that give rise to regulating negative bias against stigma. Preliminary research presented in this proposal suggests that older adults have more negative bias toward stigmatized individuals than young adults. Importantly, their bias is exacerbated by executive function decline. However, the mechanisms by which aging impairs older adults' ability to regulate negative bias remain a mystery. The current proposal presents four studies to address this question. The first study uses functional magnetic resonance imaging (fMRI) to determine if age-related cognitive decline affects older adults' social judgments, or if a secondary factor (e.g., cohort differences) may play a role in disparities that arise between young and older adults' social judgments. The second study investigates if these strategies are influenced by cognitive capacity. The third study uses fMRI to examine whether older adults rely on different neural mechanisms than young adults to actively regulate their prepotent aversive responses to stigma. The final study uses a specialized neuroimaging technique (functional connectivity) to identify potential age-related differences in neural connectivity that could impair older adults' ability to regulate negative bias against the stigmatized. The findings will shed light on the effects of aging on social cognition. Specifically, these studies will identify both the cognitive mechanisms that are impaired by aging, as well as the extent to which they decline with age. Longer term, these studies will provide the necessary foundation from which to develop interventions with older adults to promote healthy social interactions (e.g., through emotion regulation and coping mechanisms). Further, these studies will contribute to the growing research seeking to detect early warning signs in cognitive development that may be indicative of abnormalities in the aging process.

描述(由申请人提供)：本提案的目的是检查与年龄相关的认知衰退是否损害老年人对受污名化的个人的负面偏见的调节能力。已经广泛证明，衰老对认知(特别是记忆和执行功能)有有害的影响，但这些损害的程度和原因仍有广泛的争论。因此，该建议使用社会神经科学技术作为研究衰老对认知的影响的另一种方法。广泛的研究表明，执行功能在调节对污名的偏见方面发挥着核心作用。因此，这项提案将研究衰老对潜在神经机制的影响，这些神经机制引起对污名的负面偏见的调节。这项提案中提出的初步研究表明，老年人比年轻人对被污名化的个人有更多的负面偏见。重要的是，执行功能的衰退加剧了他们的偏见。然而，衰老削弱老年人调节负面偏见的能力的机制仍然是一个谜。目前的提案提出了四项研究来解决这一问题。第一项研究使用功能磁共振成像(FMRI)来确定与年龄相关的认知衰退是否会影响老年人的社会判断，或者次要因素(例如，队列差异)是否可能在年轻人和老年人的社会判断之间出现的差异中发挥作用。第二项研究调查这些策略是否受认知能力的影响。第三项研究使用功能磁共振成像来检查老年人是否依赖于不同于年轻人的神经机制来积极调节他们对污名的主要厌恶反应。最后一项研究使用一种专门的神经成像技术(功能连接)来确定神经连接中与年龄相关的潜在差异，这些差异可能会削弱老年人对受污名者的负面偏见进行调节的能力。这一发现将有助于揭示老龄化对社会认知的影响。具体地说，这些研究将确定因衰老而受损的认知机制，以及它们随着年龄的增长而下降的程度。从长远来看，这些研究将提供必要的基础，以制定针对老年人的干预措施，以促进健康的社会互动(例如，通过情绪调节和应对机制)。此外，这些研究将有助于越来越多的研究寻求发现认知发展中的早期预警迹象，这些迹象可能表明衰老过程中的异常。
