Multiple choice

Different thresholds

  1. occur when we can first detect some stimulus

  2. occur when we can detect the change in the intensity of a stimulus

  3. depend on the energy necessary to stimulate a sensory receptor

  4. are measured in Judgmental Normal Differences
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Difference threshold refers to the minimum change in stimulus intensity that can be detected. This is also called Just Noticeable Difference (JND). Option A describes absolute threshold, C describes energy for receptors, and D is not a real measurement term. Difference thresholds are about detecting CHANGES, not initial detection.
