UNIT 3 Visual Organization and Interpretation
| Question | Answer |
|---|---|
| Gestalt | an organized whole. Gestalt psychologists emphasized our tendency to integrate pieces of information into meaningful wholes. |
| Figure-ground | the organization of the visual field into objects (the figures) that stand out from their surroundings (the ground). |
| Grouping | the perceptual tendency to organize stimuli into coherent groups. |
| Depth Perception | the ability to see objects in three dimensions although the images that strike the retina are two-dimensional; allows us to judge distance. |
| Visual Cliff | a laboratory device for testing depth perception in infants and young animals. |
| Binocular Cue | a depth cue, such as retinal disparity, that depends on the use of two eyes. |
| Retinal Disparity | a binocular cue for perceiving depth. By comparing retinal images from the two eyes, the brain computes distance- the greater the disparity (difference) between the two images, the closer the objects. |
| Phi Phenomenon | an illusion of movement created when two or more adjacent lights blink on and off in quick succession. |
| Perceptual Constancy | perceiving objects as unchanging (having consistent color, brightness, shape, and size) even as illumination and retinal images change. |
| Color Constancy | perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object. |
| Perceptual Adaptation | the ability to adjust to changed sensory input, including an artificially displaced or even inverted visual field. |
