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. Comes from the complexity of the sound wave






2. Or overlap of objects shows which objects are closer






3. 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.






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






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






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






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






8. Defined the Just Noticeable Difference






9. 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






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






11. Has monocular and binocular cues






12. 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


13. 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.






14. 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.






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






16. Asserts that perception and cognition are largely innate






17. Proposed the perceptual development and optic array






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






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


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






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






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






23. 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'






24. 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.






25. 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






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






27. 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






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






29. 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






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






31. 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






32. The physical intensity of light






33. 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






34. We see objects because of the light they reflect






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






36. The chemical that aids the receptor cells in transduction






37. How we organize or experience sensations






38. humans best hear at






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






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






41. Saying you detect a stimulus that is not there






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






43. The feeling that results from physical stimulation






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






45. 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






46. Correctly sensing a stimulus






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






48. 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.






49. 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






50. 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.
