  1. Chapter 3 Powerpoint Questions

  2. Q1 Transduction

  3. A1 • The process of converting outside stimuli, such as light, into neural activity.

  4. Q2 • Frequency

  5. A2 • Number of complete waves, or cycles, that pass a given point per unit of time

  6. Q3 • Three properties of sound waves

  7. A3 • Wavelength, amplitude, purity

  8. Q4 • Photons

  9. A4 • Tiny particle packets of waves

  10. Q5 • Synesthesia

  11. A5 • Disorder in which the signals from the various sensory organs are processed in the wrong cortical areas, resulting in the sense information being interpreted as more than one sensation.

  12. Q6 • Sound

  13. A6 • Vibrations of the air molecules around us

  14. Q7 • Who first proposed that light is actually tiny packets of waves

  15. A7 • Albert Einstein

  16. Q8 • Three psychological principles of light

  17. A8 • Brightness; color; saturation

  18. Q9 • Somatic pain

  19. A9 • Detected by receptors in the skin, muscles, tendons, and joints

  20. Q10 • Subliminal perception and advertising

  21. A10 • We do perceive sensory information subliminally but it does not influence our voluntary actions such as purchasing objects

  22. Q11 • Saccadic movement

  23. A11 • The small movements made by the eyes that are generally not consciously noticed by individuals but that keep us from becoming adapted to visual sensory input

  24. Q12 • Sensation

  25. A12 • The process that occurs when special receptors in the sense organs are activated, allowing various forms of outside stimuli to become neural signals in the brain.

  26. Q13 • Opponent-process theory

  27. A13 • Theory of color vision that proposes visual neurons are stimulated by light of one color and inhibited by light of another color

  28. Q14 • Somatic pain is a signal of

  29. A14 • The body being damaged or about to be damaged

  30. Q15 • The location to which the thalamus sends sensory information.

  31. A15 • Cerebral cortex

  32. Q16 • Rods

  33. A16 • Visual sensory receptors found at the back of the retina, responsible for non-color sensitivity to low levels of light

  34. Q17 • Skin senses

  35. A17 • The sensation of touch, pressure, temperature, and pain.

  36. Q18 • Visceral pain

  37. A18 • Pain detected by receptors in the organs

  38. Q19 • Cones

  39. A19 • Visual sensory receptors found at the back of the retina, responsible for color vision and sharpness of vision

  40. Q20 • Hearing damage caused by a damaged eardrum or damage to the bones of the middle ear

  41. A20 • Conduction hearing impairment

  42. Q21 • Sensory adaptation

  43. A21 • Tendency of sensory receptor cells to become less responsive to a stimulus that is unchanging

  44. Q22 • Color blindness

  45. A22 • Vision that is color deficient due to having either no cones or cones that do not work properly

  46. Q23 • The pathway that visual information takes to the occipital lobe

  47. A23 • Lateral geniculate nucleus

  48. Q24 • Key point to remember about habituation

  49. A24 • In habituation the sensory receptors are still responding to stimulation but the lower centers of the brain (cerebellum) are not sending the signals from those receptors to the cortex.

  50. Q25 • Light sensitive area at the back of the eye containing three layers including the ganglion cells, bipolar cells, and photoreceptors
