Monocular Cues Current Lecture: Color Vision Continued I. Color Visiona. Color Constancy: perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object II. Perception Can Be Influenced By: a. Ambiguous Stimulib. Contextc. Previous Experienced. Expectancies III. Form Perceptiona. Figure-Ground: the organization of the visual field into objects (figures) that stand out from their surroundings (ground). b. Grouping: the perceptual tendency to organize stimuli into coherent groupsi. Proximity: nearby objects go togetherii. Similarity: similar objects go togetheriii. Continuity: we perceive smooth, continuous patterns rather than discontinuousiv. Connectedness: when uniformed or linked we perceive items as a single unitc. Closure: we fill in gaps to create a complete, whole objectIV. Depth Perceptiona. Binocular Cuesi. Retinal Disparity: the greater the difference between the two images the retina receives of an object, the closer the object is to the viewerii. Convergence: the extent to which the eyes converge inward when lookingat an object b. Monocular Cuesi. Interposition: object in front blocks ii. Relative Size: if objects same size, the one that casts a smaller retinal image is farther awayiii. Relative Height: objects higher in the field of vision are farther away iv. Relative Motion: as we move, stable objects move with usv. Linear Perspective: parallel lines converge with distancevi. Light & Shadow: nearby objects reflect more light to our eyes; light comesfrom aboveReview for Test Monday, October
