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






2. Is the upper limit above which the stimuli can no longer be perceived. -The highest pitch sound a human could hear






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






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






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






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






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






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






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






10. 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






11. Proposed the perceptual development and optic array






12. Correctly sensing a stimulus






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






14. Or overlap of objects shows which objects are closer






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






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






17. 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






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






19. 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.






20. Asserts that perception and cognition are largely innate






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






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






23. Along the visual pathway is the...






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






25. The optic nerve is made up of...






26. 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'






27. Rightly stating that no stimulus exists






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






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






30. Defined the Just Noticeable Difference






31. Proposed the opponent color/process theory






32. 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






33. 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.






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






35. 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.






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






37. Curces are graphical representations of a subject'S sensitivity to a stimulus






38. The tendency to perceive a smooth motion. This explains why motion is perceived when there is none - often by the use of flashing lights or rapidly shown still-fram pictures - such as in the perception of cartoons. This is apparent motion






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






40. Why do cones see better than rods?






41. 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






42. How we organize or experience sensations






43. 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.






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






45. 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






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






47. humans best hear at






48. Found that infants prefer relatively complex and sensational displays






49. 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






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