Psychophysicists define sensory adaptation as:
A)the tendency of sensory systems to increase sensitivity to a constant source of stimulation
B)the intensity level at which people can detect the presence of a stimulus 50% of the time
C)the tendency of sensory systems to reduce sensitivity to a constant source of stimulation
D)the smallest difference in the magnitude of two stimuli that an observer can reliably detect

Question

Quizplus · Accepted Answer

Sensory adaptation is the tendency of sensory systems to reduce sensitivity to a constant source of stimulation. This allows the sensory system to adjust to a constant background stimulation and focus on detecting any changes or variations in the stimulation. A is incorrect as it describes sensory facilitation. B is incorrect as it describes the threshold for detecting a stimulus. D is incorrect as it describes the just noticeable difference.
