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






2. Located by the cornea






3. 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






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






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






6. Saying you detect a stimulus that is not there






7. 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

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






12. 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






13. Comes from the complexity of the sound wave






14. Correctly sensing a stimulus






15. Rightly stating that no stimulus exists






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

18. Asserts that perception and cognition are largely innate

21. Best at seeing fine details






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






23. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.

25. 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.

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






28. 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.






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






30. 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

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






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






46. 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






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






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






49. The physical intensity of light






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