  1. Sensation and Perception

  2. Preassement to Sensation and Perception

  3. Question 1 • You can see color in your peripheral vision

  4. FALSE

  5. Question 2 • Receptor cells allow you interpret what is going on your world

  6. TRUE

  7. Question 3 • Sensation refers to the process of getting information from the world to our brain.

  8. TRUE

  9. Question 4 • If you stay in a hot tub it will seem as hot as it did when you first got in it. Sensory adaptation refers to the decline in sensitivity to a constant stimuli.

  10. FALSE

  11. Question 5 • Our interpretations of the world are due to our personal sensations.

  12. FALSE

  13. Question 6 • The colored part of the eye, which is actually a ring of muscles that controls the size of the pupil, is called the iris

  14. TRUE

  15. Question 7 • The eardrum is interprets sound waves for the brain so that we can hear.

  16. FALSE

  17. Question 8 • People judge people based on what groups they belong

  18. TRUE

  19. Question 9 • On a clear, dark night we can see a candle flame 30 miles away.

  20. TRUE

  21. Question 10 • Advertisers are able to shape our buying habits through subliminal messages

  22. FALSE

  23. Question 11 • If we stare at a green square for a while and then look at a white sheet of paper, we can see red

  24. TRUE

  25. Question 12 • If we close our eyes and hold our nose, we cannot taste the difference between an apple and a raw potato.

  26. TRUE

  27. Question 13 • If required to look through a pair of glasses that turns the world upside down, we soon adapt and coordinate our movements without difficulty.

  28. TRUE

  29. Question 14 • If people are told that an infant is “David”, they are likely to see “him” as bigger and stronger that if the same infant is called “Diana.”

  30. TRUE

  31. Question 15 • Laboratory evidence clearly indicates that some people do have ESP

  32. FALSE

  33. Our Essential Questions!  • How do sensations and perceptions differ? • How do the senses transform information into brain messages? • What is the nature of attention?

  34. Grab a scrap sheet of paper • Write down your definition of • sensation • perception

  35. Let’s brainstorm… • Sensation Perception

  36. Sensation • The process by which our sensory systems (eyes, ears, and other sensory organs) and nervous system receive stimuli from the environment • A person’s awareness of the world

  37. Perception The process of integrating, organizing and interpreting sensations.

  38. Bottom-Up Processing • Information processing that focuses on the raw material entering through the eyes, ears, and other organs of sensation

  39. Top-Down Processing • Top-Down Processing: • expectations and experiences influence how we interpret incoming sensory information

  40. Sensation v Perception • Complete the worksheet

  41. The Major Senses • 7 major senses • Vision (most studied) • Hearing • Touch • Smell • Taste • Vestibular • Kinesthetic

  42. http://www.youtube.com/watch?v=YuYrPB2i-_8

  43. The Riddle of Separate Sensations • Sense receptors • specialized cells unique to each sense organ that respond to a particular form of sensory stimulation

  44. Sensory Receptors – An Example • When you bite into a crisp apple, you hear the crunch, you taste the sweetness, you feel the smooth skin, you see the red, and you smell the aroma.

  45. Receptor Cells • Each of the seven senses is specifically coded to only take in one type of stimulus, whether it be light waves, sound waves, smell, taste, or touch.

  46. What Does That Mean? • Turn to your neighbor and tell them what sensation means. • What is with those blasted receptor cells as well… explain what they do

  47. Principles of Sensation • Transduction • Absolute threshold • Difference threshold • Sensory adaptation

  48. Transduction • The process by which a form of physical energy is converted into a coded neural signal that can be processed by the nervous system.

  49. What is a Threshold?
