| You would not be able to hear a sound that was below your absolute threshold for hearing. | True |
| People who live in cities gradually become less bothered by traffic noise because of the process called sensory perception. | True |
| Something that is variable is subject to change. | True |
| Visual _______________________ is a measure of the sharpness of a person’s vision. | Acuity |
| An _______________________ is the visual impression that remains when an image is removed. | Afterimage |
| The _______________________ is an opening in the eye through which light enters. | Pupil |
| Neurons in the eye that are sensitive to light are called _______________________. | Photoreceptors |
| _______________________ colors are located across from each other on the color circle. | Complementary |
| “I am an area in the eye that lacks photoreceptors.” | Blindspot |
| “I am the part of the eye that acts like film in a camera.” | Retina |
| “I am the inability to distinguish colors from each other.” | Color blind |
| “I am a region in the back of the brain that processes visual information.” | Visual acuity |
| “I focus vision by changing thickness, based on the distance of an object being viewed.” | Afterimage |
| Hearing aids can help people who have _______________________ deafness. | Conductive |
| The cochlea is part of the _______________________ ear, which is protected by a layer of tough bone. | Inner |
| Disease and prolonged exposure to very loud sounds can lead to nerve damage and _______________________ deafness. | Sensorineural |

| Visual cues that only need one eye to be perceived | Monocular cues |
| The tendency to perceive a complete or whole figure even though gaps exist | Closure |
| Visual cues that require both eyes to be perceived | Binocular cues |
| The use of the rapid progression of still images or objects to produce the illusion of movement | Stroboscopic motion |
| A binocular cue for perceiving depth, based on the difference between the two images of an object that the retina receives as the object moves closer | Retinal disparity |
