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

23. 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.
Differential Threshold
Outer ear
Retina
Inner ear
24. 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
Constancy

25. Curces are graphical representations of a subject'S sensitivity to a stimulus
Visual Pathway
Receiver operating characteristic
Phi Phenomenon

26. 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.
Receiver operating characteristic
Autokinetic effect
Optic Chasm
False alarm
27. 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
