If a stimulus is just slightly weaker than the absolute sensory threshold, how often would we expect a person to be able to identify its presence?

Question

Quizplus · Accepted Answer

The absolute sensory threshold is the intensity level at which a stimulus is detected 50% of the time. If the stimulus is slightly weaker than the absolute sensory threshold, we would expect a person to identify its presence a little less than half the time (less than the 50% detection rate at the absolute threshold). Therefore, the best choice is D.
