Do women tend while men fight or flee? Differential emotive reactions of stressed men and women while viewing newborn infants

Infant care often is carried out under stressful circumstances. Little is known about differences in caretaking motivation between men and women under stress. In the present study, stress was induced in 40 participants (21 women, 19 men) by means of the cold pressor stress test, 40 (22 women, 18 men) serving as controls. Participants then rated their urge to care for newborn infants shown on 20 short video clips. The infants in the videos were either crying (N = 10) or were showing typical neonatal facial movements (N = 10). Skin conductance was obtained while participants viewed the videos and salivary cortisol was measured to capture stress responses. We found sex differences in caretaking motivation, such that stress led to decreased caretaking motivation in men but not in women. Furthermore, stressed men elicited a stronger skin conductance change while viewing infant videos than stressed women. These findings provide further evidence for differential stress reactions in men and women and may have crucial implications for parental care.
