Pupillary Response
The Pupillary Response refers to the constriction or dilation of the pupil of the eye in response to certain stimuli. One such stimulus is light condition. When there is little light, the pupil dilates to let more light in. The opposite happens when exposed to bright light. The pupils also dilate when we are interested in something, or when presented with a novel stimulus, or when sexually aroused.
People think they can destress and regulate their emotions by using only their minds.
