Perception

The process of organizing and interpreting information, enabling us to recognize meaningful objects and events.

• Visual Capture: the tendency for vision to dominate the other senses.
• Gestalt Psychology: Gestalt means "an organized whole." These psychologists emphasize our tendency to integrate pieces of information into meaningful wholes.
• Gestalt Philosophy: the whole is greater than the sum of its parts.
• Figure-Ground Relationship: the organization of the visual field into objects(figures) that stands out from their surroundings(ground).
• Grouping: the perceptual tendency to organize stimuli into groups that we understand.
• Proximity: where we group similar figures together.
• Similarity: we group similar figures together.
• Continuity: we group continuous patterns together.
• Connectedness: we group together uniform and linked figures.
• Depth Perception: the ability to see objects in three dimensions although the images that strike the retina are two dimensional.
• How do we transform 2D objects to 3D perception?
• Binocular Cues: depth cues that depends on two eyes.
• Retinal Disparity: a binocular cue for seeing depth. The closer an object comes to you the greater the disparity in between the two.
• Monocular Cues: depth cues that depends on two eyes.
• Interposition: if someone is blocking our view, we perceive it as closer.
• Relative Size: if we know that two objects are similar in size, the one that looks smaller is farthest away.
• Relative Clarity: we assume hazy objects are farther away.
• Texture Gradient: the coarser it looks the closer it is.
• Relative Height: things higher in our field of vision, they look farther away.
• Relative Motion: things that are closer appear to move more quickly. Linear Perspective: parallel lines seem to converge with distance.
• Light and Shadow: dimmer objects appear farther away because they reflect less light.
• Phi Phenomenon: an illusion of movement created when two or more adjacent lights blink on and off in succession.
• Perceptual Consistency: perceiving objects as unchanging even as illumination and retinal images changes.
