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






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






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






4. humans best hear at






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






6. Rightly stating that no stimulus exists






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






8. Best at seeing fine details






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






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






11. Is the result of regeneration of retinal pigment






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






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






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. Has monocular and binocular cues






16. The physical intensity of light






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






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






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






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






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






22. Defined the Just Noticeable Difference






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






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






25. 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.






26. Along the visual pathway is the...






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






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






29. 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






30. 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






31. The moon looks larger when we see it on the horizon than when we see it in the sky. This is because the horizon contains visual cues that make the moon seem more distant than the overhead sky.






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






33. 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






34. 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






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






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






37. 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'






38. We see objects because of the light they reflect






39. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.






40. 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






41. Asserts that perception and cognition are largely innate






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






43. 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






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






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






46. Saying you detect a stimulus that is not there






47. 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

48. 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.






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






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