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

Reception
Mental set
2. The center of the retina; has the greatest visual acuity

3. 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

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

5. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.

6. 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.

9. 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
Perceptual Development

Timbre
Muller-Lyer Illusion
10. Asserts that perception and cognition are largely innate
Response Bias

Proximity
Nativist Theory
11. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses
Thomas Young and Hermann von Hemholtz
Response Bias

Robert Frantz
17. It travels through the horizontal cells to the bipolar cells to the amacrine cells. Finally the information heads to the ganglion cells.
texture gradient

After light passes through receptors
18. 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
Inner ear
Receiver operating characteristic
texture gradient
Visual Cliff
19. 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.
Purkinje shift
Lateral Inhibition
Cones
Timbre
20. Best at seeing fine details
Visual Acuity
binoculary disparity
Weber'S Law
Photopigments
21. 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

Sensation
23. All the things a person sees trains them to perceive

Vision
24. 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
Ponzo Illusion
Photopigments
Autokinetic effect
E.H. Weber
25. 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
Retina
Rods
Striate cortex to the visual association areas of the cortex
David Hubel and Torsten Wiesel
26. Saying you detect a stimulus that is not there
Sensation
False alarm
Hue
Differential Threshold
27. Consists of the parts you see called the pinna and the auditory canal. Vibrations from sound move down this canal to the middle ear.
Neural Pathways
Eleanor Gibson and Richard Walk
Phi Phenomenon
Outer ear
28. 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.
