Hallucination - An imaginary sensation such as seeing, hearing, or smelling something that does not exist in the external world. 22. Hyperopia - Difficulty focusing nearby objects (farsightedness). 23. Myopia - Difficulty focusing distant objects (nearsightedness). 24. Peripheral vision - Vision at the edges of the visual field. 25. Visual acuity - The sharpness of visual perception. 26.

Semicircular canals - three interconnected tubes located inside each ear that are filled with fluid that respond to the movements of your head and are the sensory organs for balance. 14. Gustation - The sense of taste. 15. Olfaction - The sense of smell. 16. Anosmia - the inability to perceive odor 17. Reminding system - Pain based on small nerve fibers; reminds the brain that the body has been injured. 18. Sensory conflict theory - Explains motion sickness as the result of a mismatch among information from vision, the vestibular system, and kinesthesis. 19. Warning system - Pain based on large nerve fibers; warns that bodily damage may be occurring. 20. Somesthetic senses - Sensations produced by the skin, muscles, joints, viscera, and organs of balance. 21. Referred pain - Pain that is felt in one part of the body but comes from another. 22. Visceral Pain: Pain that is felt when internal organs are damaged or injured. 23. Tympanic membrane - a thin membrane that separates the external ear from the middle ear and transmits sound waves from the air to the ossicles inside the middle ear. 24. Ossicles - three tiny bones in the middle ear that transmit and amply vibrations from the tympanic membrane to the fluid-filled cochlea. 25. Oval window - a connective tissue membrane located at the head of the cochlea that connects the middle and inner ear and through which sound vibrations are transmitted. ## Unit 4 Vocabulary Quiz 4 1.

Shape constancy - The perceived shape of an object is unaffected by changes in its retinal image. 12. Size constancy - The perceived size of an object remains constant, despite changes in its retinal image. 13. Stroboscopic movement - Illusion of movement in which an object is shown in a rapidly changing series of positions. 14. Stereoscopic vision - Perception of space and depth due to the fact that the eyes receive different images. 15. Pictorial depth cues - Monocular depth cues found in paintings, drawings, and photographs that impart information about space, depth, and distance. 16. Cocktail Party Effect - The ability to focus one's listening attention on a single talker among a mixture of conversations and background noises while ignoring other conversations 17. Gestalt Principles – Perception principles that attempt to predict how people organize visual elements into meaningful groups or unified wholes. 18. Law of Similarity - a Gestalt principle of organization stating that parts of a stimulus field that are similar to each other tend to be perceived as belonging together as a unit 19. Law of Continuity – a Gestalt principle of organization stating that there is a tendency to perceive an object as continuing in its established direction and therefore the eye is compelled to move through an object 20. Law of Closure – a Gestalt principle of organization stating that there is a tendency to perceive incomplete objects as complete by filling in gaps in stimuli and organizing asymmetric stimuli as symmetric 21. Law of Proximity – a Gestalt principle of organization stating that objects or events that are near to one another in space or time are perceived as belonging together as a unit
