  1. 4. The nerve that carries neural impulses from the eye to the brain.
  2. 7. Failing to see visible objects when our attention is directed elsewhere.
  3. 9. The central focal point in the retina, around which the eye's cones cluster.
  4. 12. the light sensitive inner surface of the eye, containing the receptors rods and cones plus layers of neurons that begin the processing of visual information.
  5. 13. The transparent structure behind the pupil that changes shape to help focus images on the retina.
  6. 14. the point at which the optic nerve leaves the eye, creating a "blind" spot because no receptors cells are located there.
  7. 15. The adjustable opening in the center of the eye through which light enters.
  8. 16. Protects the eye when bending the amount of light to start focusing it and its also where the light enters first.
  9. 20. Conversion of one form of energy into another. In sensation, the transforming of stimulus energies, such as sights, sounds, and smells into neural impulses our brain can interpret.
  10. 21. Below one's absolute threshold for conscious awareness.
  11. 22. The study of relationships between the physical characteristics of stimuli, such as their intensity on our psychological experience of them.
  12. 24. The minimum differences between two stimuli required for detection 50% of the time.
  13. 25. A ring of muscle tissue that forms the color portion of the eye around the pupil that controls the size of the pupil opening.
  14. 26. The focusing of conscious awareness on a particular stimulus.

  1. 1. failing to notice changes in the environment.
  2. 2. The minimum stimulation needed to detect a particular stimulus 50 percent of the time.
  3. 3. The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events.
  4. 5. a theory predicting how and when we detect the presence of a faint stimulus amid background stimulation.
  5. 6. Analysis that begins with the sensory receptors and works up to the brain's integration of sensory information.
  6. 8. diminished sensitivity as a consequences of constant stimulation.
  7. 10. When the object to the preference is switched with another one, do not acknowledge the difference and tend to find explanations for this altered choice.
  8. 11. A mental predisposition to perceive one thing and not another.
  9. 17. Information processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectation.
  10. 18. decreasing responsiveness with repeated stimulation.
  11. 19. The principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage.
  12. 23. The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
