PURPOSE:Binocular rivalry arises when incompatible images are presented one to each eye.If the two eyes conflicting information were invisible with identical perceptual interpretations,does rivalry competition still occur? The current study investigated whether binocular rivalry can be induced from conflicting but invisible spatial patterns.

PURPOSE:One paradox in primate vision concerns the increasing complexity of encoded features while spatial frequency (SF) selectivity decreases drastically along the visual hierarchy.
PURPOSE:To investigate the changes of resting-state interhemispheric functional connectivity in the brain of the ametropic amblyopia patients.
PURPOSE:Size constancy is essential for object recognition and spatial perception.Currently,two hypotheses explained the mechanisms of size constancy differently:the relational theory emphasizes the r
目的：左右眼视图呈现时间异步(temporal interocular asynchrony,TIOA)可以产生对隐藏平面的定量深度感知,双眼匹配信息在这种立体视觉中有重要作用。本文进一步研究了双眼匹配和不匹配信息存在空间和时间上差异时,对定量深度感知的影响。方法：在阈值范围内分别改变双眼匹配和不匹配信息间的水平距离差、深度空间差以及双眼不匹配信息产生之前匹配信息的消失时间,被试对于隐藏平面进行深
PURPOSE :Motion perception is important for human beings to interplay with environment,such as walking through the street to avoid moving vehicles.
目的：探究轮廓整合所涉及脑区在加工过程中的相对作用及其动态交互加工机制。方法：实验一结合功能磁共振成像技术来考察不同层级视皮层在轮廓整合加工过程中的动态变化。实验二通过实时经颅磁刺激技术进一步在因果关系上验证了轮廓整合的动态回返加工机制。结果：实验一发现高级脑区(V3B,LO)以持续增强的方式表征轮廓信息,而低级视皮层(V1,V2)则表现出激活再激活的表征模式,这些结果提示轮廓整合涉及反馈加工。实
目的：心理物理学函数描述了被试对特定刺激强度的反应正确率，是心理物理学研究的基本方法。我们提出了一种非参贝叶斯估计方法——高斯过程分类——来估计心理物理学函数。方法：该估计方法对函数内在模型不做出任何限制，而仅仅假定函数的连续性和光滑性，由采集的数据直接估计出心理物理学函数。我们通过蒙特卡洛仿真考察了该方法在常见实验条件下的估计效率和精确度，并在心理物理学实验中加以验证。结果：仿真实验发现该非参方
目的：本研究利用持续闪烁抑制范式测量弱视和正常被试的抑制效应.与正常视觉群体相比，单眼屈光参差型和斜视型弱视患者都存在较为严重的眼间抑制.因此我们推测，在本任务中，相对于好眼，弱视眼受到的抑制应更为严重.方法：20名屈光参差型弱视患者(平均年龄18.2±1.2岁)和17名正常被试(平均年龄22.9±0.5岁)参与，采用心理物理法呈现刺激.结果：与弱视被试相比，正常人的优势眼与非优势眼在三种空间频率
