Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. After the optic chasm - information travels to the...






2. Located by the cornea






3. Defined the Just Noticeable Difference






4. Applies to all senses but only to a limited range of intensities. The law states that a stimulus needs to be increased by a constant fraction of its original value in order to be noticeably different

5. The most famous of all visual illusions. Two horizontal lines of equal length appear unequal because of the orientation of the arrow marks at the end. Inward facing arrow marks make the line appear shorter than another line of the same length with ou






6. Are concentrated in the center of the retina. They are sensitive to color and daylight vision.






7. The chemical that aids the receptor cells in transduction






8. Gives us clues about how far away an object is if we know about how big the object should be






9. Comes from the complexity of the sound wave






10. The feeling that results from physical stimulation






11. The clear protective coating on the outside of the eye






12. How we organize or experience sensations






13. Developed the visual cliff to study whether depth perception was innate






14. Electrical impulses travel down these to the brain - where the information is understood






15. Is the tendency to see what is easiest or logical to see






16. Refers to the entire span that can be perceived or detected by the eye at a given moment.






17. Refers to the relationship between the meaningful part of a picture and the background






18. A theory for color vision. It suggests that two types of color sensitive cells exist: Cones that respond to blue-yellow colors and cones that respond to red-green. When one color of the cone is stimulated - the other is inhibited.






19. Proposed the perceptual development and optic array






20. Also known as color - is the dominant wavelength of light






21. Takes place when receptors for a particular sense detect a stimulus.






22. Proposed the opponent color/process theory






23. Involves both innate/sensory and is partially learned/conceptual






24. Located in the back of the eye - receives light images from the lens. It is composed of about 30 million photoreceptor cells and of other cell layers that process information






25. Ambiguous figures - such as the Rubin vase. They can be perceived as two different things depending on which part you see as the figure and which part you see as the background.






26. 1. closure 2. Proximity 3. Continuation or good continuation 4. Symmetry 5. Constancy 6. Minimum principle






27. 1. Reception 2. Sensory Transduction 3. Neural Pathways






28. Is the tendency to create a whole or detailed figure based on our expectations rather than what is seen






29. He tendency to group together items that are near each other






30. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright






31. Correctly sensing a stimulus






32. Consists of the parts you see called the pinna and the auditory canal. Vibrations from sound move down this canal to the middle ear.






33. Knowing that an elephant is large no matter how it might appear






34. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance






35. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc






36. The part of the world that triggers a particular neuron






37. The center of the retina; has the greatest visual acuity






38. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'






39. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.






40. Rightly stating that no stimulus exists






41. All the things a person sees trains them to perceive






42. We see objects because of the light they reflect






43. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.






44. Found that infants prefer relatively complex and sensational displays






45. Is knowing the color of an object even with tinted glasses on






46. Is the tendency to complete incomplete figures






47. Famous for the theory of color blindness






48. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.






49. Failing to detect a present stimulus






50. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl
