Subjects : gre, psychology
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. Is the tendency to see what is easiest or logical to see






2. Is the inability to recognize faces






3. 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






4. How we organize or experience sensations






5. Revolves around perception and asserts that people tend to see the world as comprised of organized wholes. The world is understood through top-down processing.






6. Found that infants prefer relatively complex and sensational displays






7. 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






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






9. Comes from the complexity of the sound wave






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

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






12. Allows the eyes to see contrast and prevents repetitive information from being sent to the brain. Once the receptor cell is stimulated - the others nearby are inhibited.






13. Defined the Just Noticeable Difference






14. 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

15. Is the minimum amount of stimuli that can be detected 50% of the time






16. Correctly sensing a stimulus






17. 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






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






19. Along the visual pathway is the...






20. 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






21. 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.






22. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.






23. The physical intensity of light






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. All the things a person sees trains them to perceive






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






27. Is the tendency to make figures out of symmetrical images






28. Saying you detect a stimulus that is not there






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






30. Rightly stating that no stimulus exists






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






32. The feeling that results from physical stimulation






33. 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.






34. Why do cones see better than rods?






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






36. 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.






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






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






39. 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'






40. After the optic chasm - information travels to the...






41. Is when two horizontal lines of equal length appear unequal because of two vertical lines that slant inward






42. 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






43. 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






44. Can be perceived as two different things depending on how you look at them






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






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






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






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






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






50. Factors into why we see what we expect to see
