Unit 1.6
Across
- 2. nerve : The nerve that carries neural impulses from the eye to the brain
- 4. sense : The sense of body movement and balance
- 6. : Below one’s absolute threshold for conscious awareness
- 7. implant : A device that converts sounds into electrical signals and stimulates the auditory nerve
- 10. : A tone’s experienced highness or lowness, depends on frequency
- 15. : The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment
- 16. : The process by which the lens changes shape to focus images on the retina
- 17. : The amount of energy in a light or sound wave, influencing brightness or loudness
- 18. : Retinal receptors that detect black, white, and gray and help with night vision
- 21. : Our system for sensing the position and movement of body parts
- 23. Helmholtz theory : The theory that the retina contains three color receptors: red, green, and blue
- 25. : The sense of smell
- 27. : The process of organizing and interpreting sensory information
- 28. process theory : The theory that opposing retinal processes enable color vision
- 31. threshold : The minimum stimulus energy needed to detect a particular stimulus 50% of the time
- 33. threshold : The minimum difference between two stimuli required for detection
Down
- 1. adaptation : Diminished sensitivity as a result of constant stimulation
- 3. : The study of relationships between the physical characteristics of stimuli and our psychological experiences of them
- 5. spot : The point at which the optic nerve leaves the eye, creating an area with no receptor cells
- 8. : A fluid-filled tube in the inner ear that triggers nerve impulses from sound waves
- 9. interaction : The principle that one sense may influence another, as when the smell of food affects taste
- 11. up processing : Analysis that begins with sensory receptors and works up to brain integration
- 12. : Conversion of one form of energy into another
- 13. ear : The innermost part of the ear containing the cochlea and vestibular sacs
- 14. : The distance from the peak of one light or sound wave to the peak of the next
- 19. detection theory : Predicts how and when we detect the presence of faint stimuli amid background noise
- 20. : The colored muscle around the pupil that controls its size
- 22. : The sense or act of hearing
- 24. : The eye’s clear, protective outer layer, covering the pupil and iris
- 26. detectors : Nerve cells in the visual cortex that respond to specific features such as shape or movement
- 29. : The adjustable opening in the center of the eye through which light enters
- 30. cognition : The influence of bodily sensations and gestures on thoughts and judgments
- 32. law : To be perceived as different, two stimuli must differ by a constant minimum percentage
