GRE Psychology: Perception Sensation

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






2. The physical intensity of light






3. Suggests that there are three types of receptors in the retina: cones that respond to red - blue - or green






4. Saying you detect a stimulus that is not there






5. Found that infants prefer relatively complex and sensational displays






6. Comes from the complexity of the sound wave






7. 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.






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






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






10. Along the visual pathway is the...






11. The eyes are connected to the cerebral cortex by...






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






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






14. 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






15. Proposed the opponent color/process theory






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






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






18. Is the inability to recognize faces






19. The moon looks larger when we see it on the horizon than when we see it in the sky. This is because the horizon contains visual cues that make the moon seem more distant than the overhead sky.






20. 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.






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






23. Are particularly sensitive to dim light and are used for night vision. They are also concentrated along the sides of the retina - making them extremely important for peripheral vision






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






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






26. 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.






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






28. humans best hear at






29. Best at seeing fine details






30. Defined the Just Noticeable Difference






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






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






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






34. 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






35. We see objects because of the light they reflect






36. Why do cones see better than rods?






37. Refers to how we see texture or fine detail differently from different distances






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






39. 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.






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






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






42. The chemical that aids the receptor cells in transduction






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






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






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






46. 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






47. Rightly stating that no stimulus exists






48. The pace of vibrations or sound waves per second for a particular sound - determines pitch. Frequencies are measured in Hertz






49. Allow the cornea to bend (accommodate) in order to focus an image of the outside world onto the retina






50. Located by the cornea
