The minimal stimulus necessary for detection is called the __________, while the smallest noticeable change in a stimulus is referred to as the __________.
A) absolute threshold; difference threshold
B) base value; just noticeable difference (JND)
C) response criterion; sensory constant
D) difference threshold; absolute threshold

Question

Quizplus · Accepted Answer

The absolute threshold is the minimum amount of stimulus energy necessary for a person to detect a stimulus at least 50% of the time. The difference threshold (also known as just noticeable difference or JND) is the smallest difference between two stimuli that a person can detect at least 50% of the time. Therefore, option A correctly identifies and distinguishes between the two concepts of absolute threshold and difference threshold.
