According to psychologists, the smallest difference in stimulus intensity that a specific sense can detect is

A) its sensory memory.
B) subject to sensory adaptation.
C) the absolute threshold.
D) the just noticeable difference (JND) .

Just Noticeable Difference

The minimum difference in stimulation that a person can detect 50% of the time.

Absolute Threshold

This pertains to the lowest level at which an organism can experience a sensation, marking the boundary between non-detection and detection of a stimulus.

Sensory Adaptation

The process by which sensory receptors become less sensitive to constant or repetitive stimuli over time.
