Rejection has a physiological response according to a new study published in the September print edition of the journal Psychological Science.

Researchers at the University of Amsterdam and Leiden University in the Netherlands set out to understand the psychophysiological response of hurt feelings.

During the study, when participants awaited judgment and learned they were not liked, the beat of their heart dropped and was slow to return to a normal beat.
Hurt feelings seem to go deeper than previously expected.
