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. Defined the Just Noticeable Difference
E.H. Weber
Receptor Cells

2. 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.

6. 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

The visual pathway
3 steps involving sensation

8. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.

11. 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

Size Constancy
19. Suggests that there are three types of receptors in the retina: cones that respond to red - blue - or green
Tri-color Theory (component theory)
Light
Sensation
Robert Frantz
20. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing
Perception
Optic Array
Structuralist Theory
Amplitude
21. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses
Gestalt Psychology
Ciliary Muscles
Response Bias
Weber'S Law
22. The pace of vibrations or sound waves per second for a particular sound - determines pitch. Frequencies are measured in Hertz
Outer ear
Tri-color Theory (component theory)
Frequency
Weber'S Law
23. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance

26. 1. Reception 2. Sensory Transduction 3. Neural Pathways
Receiver operating characteristic
Fovea
Vision
3 steps involving sensation
27. 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
There are fewer cones per ganglion cells
Receiver operating characteristic
binoculary disparity
3 steps involving sensation
28. Consists of the parts you see called the pinna and the auditory canal. Vibrations from sound move down this canal to the middle ear.

31. Is composed of photons and waves measured by brightness and wavelengths
Gestalt Psychology

32. 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
Cornea
