Across
- 2. (theory) states that our perception of sound depends on where each component frequency produces vibrations along the basilar membrane
- 4. the opening in your eye that allows light to enter
- 9. describes the number of waves that pass a fixed place in a given amount of time
- 10. (cue) visual info taken in by 2 eyes, enable us a sense of depth perception
- 11. (hearing loss) damage to the hair cells within the inner ear
- 14. an organized whole that is perceived as more than the sum of its parts
- 17. suggests the mind emerges from relations between the brain, body, and world
- 20. neurons—or groups of neurons—in the brain which code for stimuli
- 21. (theory) mechanism, in the spinal cord, in which pain signals sre sent up to the brain for processing to accentuate perceived pain
- 22. ability to see objects in three dimensions, including their size and how far away they are
- 25. converts light entering your eye into electrical signals your optic nerve sends to your brain, creates images you see
- 26. ability of an organism to sense sound and to process and interpret the sensations to gain information about the source and nature of the sound
- 27. binocular parallax, refers to the fact that each of our eyes sees the world from a slightly different angle
- 31. the study of the relationship between stimuli & sensation
- 34. technique in which the introduction of one stimulus influences how people respond to a subsequent stimulus
- 36. small area of the retina that contains the highest concentration of photoreceptors
- 37. fluid-filled, spiral-shaped cavity found in the inner ear that plays a vital role in the sense of hearing
- 39. where the optic nerve leaves the eye, no receptor cells are located there (place your can't see...)
- 40. (sense) creates the sense of balance and spatial orientation for the purpose of coordinating movement with balance
- 44. (theory)states that our ability to detect a signal depends not only on the strength of the signal but also on our experience, expectation, motivation, and degree of alertness
- 45. transparent part of the outer covering of the eye, through which light first passes
- 47. 2 main parts: The cochlea (hearing), and the semicircular canals (balance)
- 48. human's ability to visually differentiate between an object and its background
- 50. (phenomenon)perceptual illusion, tricks eyes into thinking still images are actually moving
- 51. (processing) our background knowledge and expectations to interpret what we see.
- 52. (theory) the mind can only register the presence of one color of a pair at a time because the two colors oppose one another
Down
- 1. small electronic device that provides a sense of sound to deaf / hard-of-hearing people
- 3. (cue) observed with just one eye
- 5. processes that allow an individual to select and focus on particular input for further processing while simultaneously suppressing irrelevant or distracting information
- 6. occurs when new information or experiences cause you to modify your existing schemas
- 7. type of perception composed of a series of stimuli of which the person is not consciously aware and gets under the influence involuntarily
- 8. [three-color theory] states that your eye has tiny cells that receive waves of light & translate them into blue, green, & red
- 12. temporary readiness to perceive certain objects or events rather than others
- 13. 3 small bones: hammer, the anvil, and the stirrup; connects to the back of the nose and throat by a narrow area called the eustachian tube
- 15. (law) says the 'just-noticeable' difference of a stimulus is a constant proportion of the original intensity of the stimulus
- 16. when an individual fails to perceive an unexpected stimulus in plain sight, result of a lack of attention, not vision defects
- 18. photoreceptor cell in retina, sensitive to light levels and help give us good vision in low light
- 19. (constancy) ability to perceive colors as constant over varying illuminations
- 23. our ability to deal with multiple stimuli simultaneously
- 24. perceived strength of a physical stimulus
- 28. (threshold) the smallest level of stimulus that can be detected (50% of the time)
- 29. (constancy) tendency to see familiar objects as having standard shape, size, color, or location regardless perspective
- 30. colored muscle that surrounds the pupil and controls the amount of light that enters the eye
- 32. refers to a pure pigment (w/o tint or shade added)..are first processed in the brain
- 33. physical feeling / perception resulting from something contacting the body
- 35. process by which we take in sensory information and pair it with previous memories to perceive the world around us
- 38. (hearing loss) the inability of sound waves to reach the inner ear
- 41. (processing) allow the stimulus itself to shape our perception, without any preconceived ideas
- 42. the study of a variety of proposed psychic phenomena by scientists
- 43. (threshold) the minimum required difference between two stimuli for a person to notice change (50% of the time)
- 46. (chemo, thermo, mechano, or photo) help us learn about the environment around us
- 49. concentrated near the fovea, responsible for color vision, and able to adapt quickly to changes in light
