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






2. Revolves around perception and asserts that people tend to see the world as comprised of organized wholes. The world is understood through top-down processing.






3. 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






4. Rods and cones on the retina that are responsible for sensory transduction.






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






6. 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

7. 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'






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






9. The feeling that results from physical stimulation






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






11. 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






12. Comes from the complexity of the sound wave






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






14. 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






15. Is the result of regeneration of retinal pigment






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






17. Why do cones see better than rods?






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






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






20. 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






21. Defined the Just Noticeable Difference






22. 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.






23. Saying you detect a stimulus that is not there






24. Correctly sensing a stimulus






25. The chemical that aids the receptor cells in transduction






26. Rightly stating that no stimulus exists






27. 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






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






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






30. 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






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






32. Famous for the theory of color blindness






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

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






35. Or overlap of objects shows which objects are closer






36. Best at seeing fine details






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






38. Proposed the perceptual development and optic array






39. Along the visual pathway is the...






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






41. Has monocular and binocular cues






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






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






44. Located by the cornea






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






46. 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






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






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






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






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