Abstract周遭的世界每时每刻都在向我们的各个感觉通道提供丰富的信息,跨通道的
信息整合是加工这些信息的有效途径。但是,目前对于这个领域的研究并不充
分,尤其是嗅觉与视觉之间的整合过程。虽然分别加工化学与物理两种不同类
别的信息,嗅觉与视觉却具有相同的功能:物体辨认、环境导航、社会交流。
本文针对嗅视整合领域中的空白,展开 3  项研究,试图进一步揭示嗅视整合的
知觉效应及神经机制。具体如下:
     (1)  研究一采用点探测任务和视觉搜索任务,检验嗅觉信息是否能够以
        一种基于物体的方式调节视觉注意;
     (2)  研究二采用功能性核磁共振成像技术,探索场景知觉中嗅视整合的
        内在神经机制;
     (3)  研究三采用人体生物运动的性别判断任务,测量社会性神经肽对于
        整合化学感觉和视觉社会线索信息的作用。   
Other AbstractHuman senses are immersed in immense environmental inputs. Synthesizing
information from cross-modal stimuli has proven to be an efficient means to process external events,   yet not much is known regarding the integration between olfaction and vision. Seemingly distal, the two senses serve the same purposes of object identification, environmental navigation and social communication in the course of evolution. Here three studies are carried out in an effort to reveal the behavioral advantage and the underlying neurobiological mechanisms of olfactory-visual integration. Specifically,
(a)   Study I employs the dot-probe and the visual search paradigms to test whether olfaction modulates visual attention in an object-based manner;
(b)   Study II uses functional magnetic resonance imaging to explore the neural
      correlates of olfactory-visual integration in scene perception;
(c)   Study III examines how the interplays between chemosensory and visual social  cues are subject to the effect of social neuropeptides in a gender identification
      task of point-light walkers.
