Across
- 5. the smallest amount of stimulation needed for a person to detect that stimulus 50% of the time
- 7. depth cues that can be perceived with one eye, and include relative size, relative height, linear perspective, relative motion, and light and shadow
- 9. the sense of smell
- 14. The rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone; enabling us to sense its pitch
- 15. A theory of pitch perception that suggests different portions of the cochlea are responsible for encoding different sound frequencies.
- 17. is the sense of the position and movement of body parts, enabling us to perceive the body's position and movements without relying on vision.
- 19. of physical energy, such as light, sound, or pressure, into electrical signals that can be transmitted through the nervous system.
- 20. Hearing Loss hearing impairment that occurs when sound waves are unable to pass through the outer or middle ear, can be caused by damage to the eardrum or middle ear bones
- 21. States that the just-noticeable difference between two stimuli is proportional to their magnitude.
- 22. The process by which sensory receptors receive information from the environment
- 23. The minimum amount of change needed for a person to detect a difference between two stimuli.
- 25. The light-sensitive layer of tissue at the back of the eye that contains photoreceptor cells and processes visual information before sending it to the brain.
- 26. A readiness to perceive something in a particular way based on expectations, past experiences, context, and motivations.
- 27. Size, and Perceptual Constancy-our tendency to see familiar objects as having consistent color, size and shape, regardless of changes in lighting, distance or angle of perspective
- 28. failing to notice an unexpected stimulus in plain sight because you are focused on something else
- 29. a person fails to recognize changes to their environment or visual stimuli, despite their being very obvious.
- 30. specialized nerve cells that detect environmental stimuli, translate that information, and send it to the brain.
Down
- 1. : The idea that the whole of perception is different from the sum of its parts, emphasizing how people organize visual elements into groups or unified wholes.
- 2. Proposes that we perceive color in terms of three pairs of opponent colors: red-green, blue-yellow, and black-white, which are processed in antagonistic pairs by the visual system.
- 3. Perceptual analysis based on the sensory data from the environment, without prior expectations or knowledge influencing the process.
- 4. ability to focus on a particular object while ignoring distractions and irrelevant information
- 6. Cues. Depth cues that depend on the use of both eyes, such as convergence and retinal disparity .
- 8. A spiral-shaped, fluid-filled structure in the inner ear that converts sound waves into neural signals that the brain can interpret.
- 10. Hearing loss is caused by damage to the cochlea's hair cells or the auditory nerve, often resulting in difficulty hearing faint sounds or understanding speech.
- 11. the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events
- 12. Processing- process of using prior knowledge and experiences to interpret new sensory information.
- 13. : This sense, primarily located in the inner ear, is responsible for detecting balance, spatial orientation, and movement of the head and body.
- 16. and Ground: The principle of visual perception where we tend to perceive objects as distinct from their surroundings, helping us distinguish between objects and their background in a scene.
- 18. the theory that the retina contains three different color receptors, hence RBG (red, blue, green) and these three colors combine to produce the other colors we see
- 24. : Photoreceptor cells in the retina detect light and initiate the vision process. Rods are sensitive to low light levels and contribute to night vision, while cones are responsible for color vision and visual acuity.
