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






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






3. 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






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






5. 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.






6. 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.






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






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






9. 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






10. Asserts that perception and cognition are largely innate






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






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






13. Found that infants prefer relatively complex and sensational displays






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






15. Consists of one optic nerve connection each eye to the brain.






16. Rightly stating that no stimulus exists






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






18. 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






19. 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.






20. Best at seeing fine details






21. 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

22. The feeling that results from physical stimulation






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






24. 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






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. Saying you detect a stimulus that is not there






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. 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.






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






30. Is the result of regeneration of retinal pigment






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






32. Along the visual pathway is the...






33. humans best hear at






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






35. Or overlap of objects shows which objects are closer






36. 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'






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






38. 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.






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






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






41. Is the tendency to complete incomplete figures






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






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

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






45. Proposed the opponent color/process theory






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






47. Defined the Just Noticeable Difference






48. Proposed the perceptual development and optic array






49. How we organize or experience sensations






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