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. All the things a person sees trains them to perceive






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






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






4. 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


5. 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






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






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






8. Saying you detect a stimulus that is not there






9. How we organize or experience sensations






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






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






12. 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.






13. Best at seeing fine details






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






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






16. Found that infants prefer relatively complex and sensational displays






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






18. Comes from the complexity of the sound wave






19. 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






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






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






22. We see objects because of the light they reflect






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






24. Or overlap of objects shows which objects are closer






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






26. Proposed the perceptual development and optic array






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






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






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






30. 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.






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






32. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.






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


34. 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






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






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






37. Has monocular and binocular cues






38. 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.






39. 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.






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






41. 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






42. Along the visual pathway is the...






43. The chemical that aids the receptor cells in transduction






44. The feeling that results from physical stimulation






45. Located by the cornea






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


47. 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






48. 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






49. 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.






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