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. 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






2. 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

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

4. Failing to detect a present stimulus






5. The feeling that results from physical stimulation






6. Along the visual pathway is the...






7. Correctly sensing a stimulus






8. Saying you detect a stimulus that is not there






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






10. 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.






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

12. Defined the Just Noticeable Difference






13. 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






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






15. Famous for the theory of color blindness






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






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






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






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






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






21. Asserts that perception and cognition are largely innate






22. 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






23. Proposed the perceptual development and optic array






24. 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






25. 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






26. 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.






27. 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.






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






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






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






31. 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.






32. humans best hear at






33. Best at seeing fine details






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






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






36. Or overlap of objects shows which objects are closer






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






38. 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






39. The physical intensity of light






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






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






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






43. Found that infants prefer relatively complex and sensational displays






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






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






46. 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






47. 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.






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






49. 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






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