1) perceived brightness
知觉亮度
1.
The results shows that changing a uniform luminance distribution into a nonuniform luminance distribution can raise perceived brightness effectively.
本文通过对香港太古城中心四个时装专卖店展示区域的亮度水平实况进行的现场测试及对部分顾客进行的问卷调查，从而发现为吸引消费者而提高亮度水平的做法并非只有依赖提高照度才能达到，也可以通过改变均匀的亮度分布为非均匀的亮度分布的方法，有效地提高了人们的知觉亮度。
2) visual brightness
视觉亮度
1.
Research into visual brightness theory and its image characteristics
视觉亮度理论及其图像特性研究
3) brightness sensation
亮度感觉
4) brightness vision
亮度视觉
5) Depth perception
深度知觉
1.
Because classical depth perception tester has the disadvantages of complex structure, low precision and high value, a new depth perception tester with intelligent and digitization from control to length measure was designed with the hardware such as singlechip, stepping motor and digital-displayer etc and some softwares.
针对传统深度知觉测试仪结构复杂、精度低、成本高等问题,探讨了一种基于微控制器的测试仪的硬件组成及软件设计。
2.

用深度知觉测试仪，对２４８ 名男性卡车驾驶员在视觉对象低速和高速运动条件下的深度知觉准确性进行了测量。
6) perceptual span
知觉广度
1.
Twenty-three college students participated in this experiment by measuring perceptual span,digit span,reading span and reading comprehension.
对23名大学生进行知觉广度、记忆广度和阅读理解的多项测验,探求知觉、记忆加工效率与不同语言阅读成绩和阅读眼动特性之间的关系。

障碍知觉
obstacle perception
障碍知觉(。bstacle pereeption)盲人对障碍物知觉的能力。通过观察和实验，发现盲人在临近障碍物一定距离时，能感知到障碍物的存在。盲人的障碍知觉主要来自听觉和颜面感觉(颜面压力)。当盲人行进时发出的脚步声、手杖声或口哨音触及障碍产生回音与振波，反射回来为盲人的听觉和颜面感觉所感知，两者的协调使盲人能知觉到障碍物的存在。盲人对障碍物距离远近的知觉，与盲者的经验有关，也与障碍物的形状、性质、大小、方位有关。经过训练可以改善障碍知觉的灵敏度。障碍知觉亦称“颜面知觉”、“第六感觉”。 (魏华忠撰李幸志审)
