Gestalt Principles of Form Perception: 1. Figure and Ground: A shape is perceived as a figure and the surrounding area as ground. 2. Proximity: Occurs when objects are placed close together they are perceived as a group. 3. Similarity: When objects appear similar they are perceived as a group or pattern. 4. Closure: When an object is incomplete or space is missing it is perceived as a whole. 5. Continuity: When the eye is compelled to move through one object and continue to another. Binocular Cues: 1. Convergence: The degree to which your eyes turn in to focus on a close object. 2. Binocular Disparity: The difference in the apparent position of an object as seen by both retinas. Monocular Cues: 1. Interposition: You can see an object is closer because it overlaps the other. 2. Relative Size: Comparing the size to the size of a known object. 3. Linear Perspective: Lines appear closer together as distance increases. 4. Texture Gradient:

Unformatted text preview: Objects appear closer as distance increases. Sound is produced by vibrations carried by air, water, or other mediums. What Happens When You Vary a Sound Wave’s: 1. Height/Amplitude: Loudness 2. Number of Cycles/Frequency: Pitch 3. Mixture of Sound Waves: Quality of sound Humans can perceive pitches from 20 to 20,000 Hz The Basilar Membrane is found in the cochlea of the ear and contains the hair cells that vibrate and transmit impulses to the brain. Pitch Theories: 1. Place Theory: Highest frequency sounds vibrate hair cells near the stirrup end and lower frequency sounds vibrate hair cells at points farther along the membrane. 2. Frequency Theory: A sound wave through the fluid of the cochlea vibrates all the hair cells, which produce action potentials in synchrony with the sound waves. 3. Volley Theory: Groups ( “volleys”) of hair cells respond to each vibration by producing an action potential....
