The minimum stimulus intensity that an organism can detect is the
A) just noticeable threshold.
B) detection threshold.
C) absolute threshold.
D) signal-detect threshold.

Question

Quizplus · Accepted Answer

The absolute threshold is the minimum intensity of a stimulus that can be detected by an organism. It is the point at which a stimulus is detectable 50% of the time. The just noticeable threshold refers to the smallest difference in intensity between two stimuli that can be detected, and the detection threshold refers to the point at which a stimulus becomes detectable after it increases in intensity. The signal-detect threshold is a measure of an individual's ability to differentiate between a signal and noise.
