- Question In Image, Thank you!Question In Image, Thank you!Question 23 signals are long-lasting and work during both day and night. Auditory Olfactory Tactile VisualQUESTION 22 As "sensitivity" declines with age (in hearing or sight), which one below is not the best way to describe the necessary "threshold"? Individuals with lower sensitivity also have a lower threshold or tolerance for stimulation. As sensitivity goes down, the threshold must be higher to compensate. Individuals with a lower level of sensitivity always need more stimulation than those with higher sensitivity. none of the above
