Review Quiz #3: Sensation and Perception Chapters 5 and 6 1. Some important parts of the eye include the _________________, which changes shape to focus images on the retina, the _________________ which is a protective covering, and the ___________________ which regulates the pupil. The ____________________, which transduces light into neural impulses, contains the ___________________________ for night and peripheral vision, and _______________ which provide color and day time vision. The blind spot is found at the ______________________, where it exits the eye. 2. The lens ability to change shape to adjust light intake is called _____________________ . Visual ______________ describes the sharpness of vision. 3. Sound waves come into the ear through the ___________________ . The ______________________ converts there sound waves into vibrations. The tiny bones in the middle ear that compress sound vibrations are called the __________________ , ___________________ and ___________________ . The snail like structure where vibrations are transformed into neural impulse is called the ____________________ . The neural impulse is then sent from the basilar membrane to the _______________ lobe of the brain. 4. Absolute thresholds are the amount of stimulation required for someone to detect a stimulus _____ of the time. The minimum stimulus needed to detect a difference between 2 stimuli is called the _______ . According to _________________________ , the difference threshold for 2 stimuli remain at a constant percentage. For example if the JND between 2 can of vegetables is 10 and 12 ounces, the JND of the 30oz can would be __________ oz. 5. The trichromatic theory (Young-Helmoltz) suggests that we see color by three major receptor cells based on the colors _______________ , _____________ , and _______________ . The _________________________ theory argues that if one combination of color receptor cells are activated, the others are temporarily blocked out. 6. Color hue is determined by ________________ , while brightness is determined by __________________ . The loudness of sound is determined by _________________ of a wave, while the pitch is determined by ______________. 7. the four taste sensations are __________________ , _________________ , _______________________ , and __________________. 8. Two additional senses are ____________________ , which monitors your bodies movements (you know what parts are moving where) and the _____________________ , which controls balance. 9. The __________________________ occurs when two or more alternating blinking lights create the appearance of movement. 10. _________________________ are distance cues of visual perception which include relative size, relative motion and texture gradient. _________________________ are depth cues which include depth perception, including convergence and __________________________. All of these cues help to create perceptual grouping of an organized whole, associated with ___________________ psychology. (whole is greater than sum of parts) 11. The ______________ theory of hearing states that different sound waves trigger different parts of the cochlea, while the _____________ theory proposes that the cochlea is activated by different frequencies. 12. ______________________ processing, also known as processing, occurs when the brain organizes sensory information, and ____________________ processing occurs when a sensory image is carried to the brain.
