项目摘要

My proposal focuses on perceptual asymmetries in the auditory modality. The long-term objective of this component of my research program is to characterize the factors affecting perceptual asymmetries in an effort to understand their underlying neuro-functional and cognitive causes. The main theoretical foundation for my proposal stems from the model proposed by Hugdahl (2000) according to which the observed perceptual asymmetry in any task reflects a combination of a bottom-up component and a top-down component. The bottom-up aspect reflects stimulus content and cerebral organization, whereas the top-down aspect refers to attentional effects. However, I am proposing that other factors should be included in the top-down component. There are a number of lines of inquiries meeting the short-term objective of investigating bottom-up processes in perceptual asymmetries that I plan to pursue during the granting period. In one line of research, auditory tasks will be examined from the perspective that they have a significant memory component. My previous work of relevance suggests that a delay between target stimuli and response affects the magnitude of auditory asymmetries as well as the pattern of responding. These findings can be explained by rehearsal and its role in the observed effects. The experiments proposed in this line of research will investigate behavioral manifestations of components of memory (especially rehearsal) in dichotic listening through the manipulation of delay before retrieval with verbal and nonverbal stimuli. In this line of research, I will also focus more closely on order of report in the two-response situation to theorize on the potential role of the decision stage in auditory asymmetries. A second line of research will continue the work that I started on cross-modal affective priming in the context of dichotic listening. My student and I established that priming might work as a top-down stimulus to affect the observed auditory asymmetries. A series of experiments will extend the base findings to a one-response dichotic task, to unimodal priming, and to verbal and nonverbal stimuli. A third area of research in my proposal will focus on the potential role of the embodiment of emotions in the context of perceptual asymmetries. This line of work will involve the manipulation of motor factors during the completion of binaural and dichotic listening tasks. Other areas of inquiry might be described, depending on available space. The ultimate goal of this research is to identify tasks that provide valid and reliable measurement of perceptual asymmetries for use in the pre-surgery screening of patient with neurological impairments such as epilepsy and brain tumors. Thus, this research has strong potential significance relevant to the measurement of functional cerebral specialization while also contributing to models of perceptual asymmetries.
我的建议集中在听觉模态的感知不对称。我的研究计划的这一组成部分的长期目标是描述影响感知不对称的因素,以了解其潜在的神经功能和认知原因。我的建议的主要理论基础源于Hugdahl(2000)提出的模型,根据该模型,在任何任务中观察到的感知不对称反映了自下而上组件和自上而下组件的组合。自下而上的方面反映了刺激内容和大脑组织,而自上而下的方面是指注意力的影响。然而,我建议在自上而下的组成部分中应包括其他因素。我计划在授予期间进行一些调查,以满足调查感知不对称中自下而上过程的短期目标。在一系列研究中,听觉任务将从它们具有重要记忆成分的角度进行检查。我以前的相关工作表明,目标刺激和反应之间的延迟会影响听觉不对称的大小以及反应的模式。这些发现可以解释排练和它的作用,观察到的效果。本研究拟通过对言语和非言语刺激提取前延迟的操纵,探讨两耳分听中记忆成分(尤其是复述)的行为表现。在这一系列的研究中,我也将更密切地关注在两个反应的情况下,报告的顺序,对决策阶段在听觉不对称的潜在作用进行理论化。第二条研究路线将继续我在双耳分听的背景下开始的跨通道情感启动的工作。我和我的学生认为,启动效应可能是一种自上而下的刺激,影响了我们观察到的听觉不对称。一系列的实验将扩展的基础研究结果,以一个反应的两分任务,单峰启动,以及言语和非言语刺激。在我的建议中,第三个研究领域将集中在感知不对称背景下情感体现的潜在作用上。这项工作将涉及在完成双耳和双耳分听任务期间操纵运动因素。可根据现有篇幅说明其他调查领域。本研究的最终目标是确定任务,提供有效和可靠的测量知觉不对称性,用于术前筛查患者的神经功能障碍,如癫痫和脑肿瘤。因此,这项研究具有很强的潜在意义的功能性大脑专业化的测量,同时也有助于模型的知觉不对称。
