25 Questions

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

2. 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

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

4. Is the inability to recognize faces

5. We see objects because of the light they reflect

6. 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.

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

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

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

10. Is the tendency to complete incomplete figures

11. 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.

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

13. Asserts that perception and cognition are largely innate

14. 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

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

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

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

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

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

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

21. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.

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

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

24. Found that infants prefer relatively complex and sensational displays

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