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.

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






2. Defined the Just Noticeable Difference






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






4. humans best hear at






5. Along the visual pathway is the...






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






7. 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






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






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






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






11. 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.






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






13. Correctly sensing a stimulus






14. Rightly stating that no stimulus exists






15. Knowing that an elephant is large no matter how it might appear






16. 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






17. 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






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






19. 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

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






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






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






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






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






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






26. Has monocular and binocular cues






27. 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'






28. 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






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






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






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






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






33. How we organize or experience sensations






34. Found that infants prefer relatively complex and sensational displays






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






36. 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.






37. 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.






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






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






40. Proposed the opponent color/process theory






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






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






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






44. 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.






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






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






47. Is the tendency to complete incomplete figures






48. Comes from the complexity of the sound wave






49. We see objects because of the light they reflect






50. Proposed the perceptual development and optic array
