The purpose of this study was to ascertain if any gender differences existed in the behaviors of infants experiencing different levels of acute established pain and different levels of arousal within each level of pain. To do this, the behaviors of 152 two-week- to 12-month-old infants were videotaped and compared. ⋯ There was no gender difference in any facial or other bodily behavior. One cannot interpolate from these results that there are any gender differences in pain thresholds, only that there seem to be gender differences in behavioral responses to acute established pain.
