目的：角膜塑形术是屈光矫正的可选择性方法之一。应用硬性透气性材料，采用反转几何设计的硬镜暂时性的改变角膜曲率从而达到矫正视力的目的。在角膜塑形的过程中，角膜中央曲率逐渐变平，裸眼视力相应提高。而临床常用的视力表检测在评价角膜塑形后视功能方面有一定的局限性。本研究使用多噪音水平对比敏感度检测方法探索评估角膜塑形术过程中视功能恢复水平。

PURPOSE:The contrast sensitivity function (CSF) provides a comprehensive assessment of spatial vision in both normal and clinical populations.
PURPOSE:Aging-related declines in vision can decrease well-being of the elder.Concerning early sensory changes as in the primary visual cortex,physiological and behavioral reports seem contradictory.
PURPOSE:Perception and action are interdependent.How visual information guide movements has been extensively studied,while how movements affects vision is understudied.
PURPOSE:The N170 and the RP are both negative-going deflections in ERP that exhibit preferential activity to visually recognizable objects;occurring at ~170 and ~250 ms,respectively.
PURPOSE:Many behavioral and neuroimaging studies have shown that human decisions are sensitive to the statistical moments (mean,variance,etc.) of reward distributions.
PURPOSE:Cooperation and competition usually induce different mental construal processes,leading to assimilation and contrast effects.
目的：目前对低视力的视功能评定标准中主要依靠视力和视野,而视力表检查在低视力患者中不够精确、视野受患者主观配合度影响,这些都妨碍了对低视力患者视功能的精准评估和可能疗效的客观检测。本研究旨在探讨视觉电生理检查、黄斑微视野仪(microperimeter,MP)和瞳孔对光反射测量仪(pupillometer,PLR)在低视力视网膜变性患者的视功能精准评估中的价值。
目的：探索背外侧前额叶和后顶叶对于视觉空间工作记忆的两个存储特征——容量(记忆数量)和精度(记忆质量)的作用。方法：使用正性经颅直流电刺激仪刺激工作记忆的两个关键脑区：左侧背外侧前额叶(1DLPFC)和右侧后顶叶(rPPC),刺激之后被试完成空间工作记忆连续报告任务,记忆2个,4个或6个线条的方向,间隔1秒后尽可能精确地回忆其中某一位置上呈现过的线条的方向。
PURPOSE:Although visual perceptual learning is often location specific,learning can transfer to a new location if the new location is additionally trained with an irrelevant task (Xiao et al.,2008).He
Purpose:Experience is known to facilitate our ability to extract regularities from simple repetitive patterns to more complex probabilistic combinations (e.g.as in language,music,navigation).However,l
