- 感知心理学 感知心理学
背景情况:
- 视觉处理在形视觉和外周视觉之间有所不同.
- 萨卡德的视觉特征外观的差异挑战了人们的感知.
- 周边空间频率 (SF) 可能比叶SF高.
研究的目的:
- 调查前后的SF的视觉外观saccades.
- 检查SF在saccades期间的变化歧视.
- 确定前后段信息对歧视的影响.
主要方法:

Depth Perception and Spatial Vision
625
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Factors Affecting Perception
1.6K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
