Proximity:Proximity refers to the principle of perception where we tend to perceive elements that are near each other as part of a group or whole.
Binocular cues: Binocular cues are visual cues that require both eyes and provide information about depth and distance. Examples include binocular disparity (the difference in images seen by each eye) and convergence (the inward turning of the eyes when focusing on nearby objects).
Perceptual set: Perceptual set is our tendency to perceive stimuli in certain ways based on our expectations, experiences, and cultural influences. It can influence how we perceive nearby objects compared to distant ones.
