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. Rightly stating that no stimulus exists






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






3. Comes from the complexity of the sound wave






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






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






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






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






8. 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.






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






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






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






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






13. Proposed the perceptual development and optic array






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






15. 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

16. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.






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






18. 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.






19. 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






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

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






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






23. 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.






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






25. 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






26. Famous for the theory of color blindness






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






28. Saying you detect a stimulus that is not there






29. 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






30. It travels through the horizontal cells to the bipolar cells to the amacrine cells. Finally the information heads to the ganglion cells.






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






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






33. Why do cones see better than rods?






34. Correctly sensing a stimulus






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






36. Says that the strength of a stimulus must be significantly increased to produce a slight difference in sensation

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






38. How we organize or experience sensations






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






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






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






42. Best at seeing fine details






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






44. Or overlap of objects shows which objects are closer






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






46. The feeling that results from physical stimulation






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






48. Proposed the opponent color/process theory






49. 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.






50. 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
