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. 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.






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






3. Why do cones see better than rods?






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






5. Is the inability to recognize faces






6. 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






7. Correctly sensing a stimulus






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


9. 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






10. The chemical that aids the receptor cells in transduction






11. humans best hear at






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






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






14. 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.






15. 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






16. Along the visual pathway is the...






17. 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






18. 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






19. Or overlap of objects shows which objects are closer






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






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






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






23. The physical intensity of light






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






25. 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






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






27. Famous for the theory of color blindness






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






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






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






31. We see objects because of the light they reflect






32. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.






33. 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






34. Defined the Just Noticeable Difference






35. Asserts that perception and cognition are largely innate






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






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






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






39. Best at seeing fine details






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






41. 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'






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






43. Proposed the perceptual development and optic array






44. 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






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






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






47. 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






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






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






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