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






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






3. Famous for the theory of color blindness






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






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






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






7. Comes from the complexity of the sound wave






8. Failing to detect a present stimulus






9. Ambiguous figures - such as the Rubin vase. They can be perceived as two different things depending on which part you see as the figure and which part you see as the background.






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






11. Saying you detect a stimulus that is not there






12. Proposed the opponent color/process theory






13. 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.






14. 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






15. 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






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






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






18. Why do cones see better than rods?






19. Best at seeing fine details






20. 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

21. The physical intensity of light






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






23. 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






24. The feeling that results from physical stimulation






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






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






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






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






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






30. Found that infants prefer relatively complex and sensational displays






31. Rightly stating that no stimulus exists






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






33. Is the inability to recognize faces






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






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






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






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

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






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






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






41. The clear protective coating on the outside of the eye






42. We see objects because of the light they reflect






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






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






45. humans best hear at






46. Defined the Just Noticeable Difference






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






48. Has monocular and binocular cues






49. 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






50. 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.
