  • 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.

1. Rightly stating that no stimulus exists






2. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.






3. Why do cones see better than rods?






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






5. After images are perceived because of fatigued receptors. Because our eyes have a partially oppositional system for seeing colors - such as red-green or black-white - once on side is overstimulated and fatigued - it can no longer respond and is overs






6. 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






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






8. 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.






9. 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






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






11. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina






12. Objects that have been drawn and can be perceived but are geometrically impossible






13. Has been called the most important depth cue. Our eyes view objects from two slightly different angles - which allows us to create a 3-dimensional figure






14. The physical intensity of a sound wave largely determines loudness






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






16. Rods and cones on the retina that are responsible for sensory transduction.






17. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing






18. Along the visual pathway is the...






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

23. Found that infants prefer relatively complex and sensational displays






24. 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






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






26. Famous for the theory of color blindness






27. How we organize or experience sensations






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






29. Proposed the perceptual development and optic array






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






31. The feeling that results from physical stimulation






32. 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

33. Proposed the opponent color/process theory






34. We see objects because of the light they reflect






35. Consists of one optic nerve connection each eye to the brain.






36. 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






37. 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.






38. Is composed of photons and waves measured by brightness and wavelengths






39. Located by the cornea






40. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses






41. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.

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






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






44. The way that a single point of light viewed in darkness will appear to shake or move. the reason for this is the movement of our own eyes






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






46. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.






47. Defined the Just Noticeable Difference
