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. 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.






2. Best at seeing fine details






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






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






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






6. Curces are graphical representations of a subject'S sensitivity to a stimulus






7. 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






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

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






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






11. 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.






12. Famous for the theory of color blindness






13. How we organize or experience sensations






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






15. Is the inability to recognize faces






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






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






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






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






20. humans best hear at






21. 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.






22. Along the visual pathway is the...






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






24. Failing to detect a present stimulus






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






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






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






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






29. 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.






30. Proposed the perceptual development and optic array






31. Asserts that perception and cognition are largely innate






32. Rightly stating that no stimulus exists






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






34. Found that infants prefer relatively complex and sensational displays






35. Why do cones see better than rods?






36. 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






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






38. Comes from the complexity of the sound wave






39. 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






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






41. 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






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






43. 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






44. The chemical that aids the receptor cells in transduction






45. 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

46. 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






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






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






49. We see objects because of the light they reflect






50. Defined the Just Noticeable Difference
