Researchers found that isolated female rats subjected to a 30-minute stressor recover more quickly and mount a stronger immune response than male counterparts. This difference may be related to the demands of motherhood, which has evolved to provide females with protection against trauma.
Researchers investigated how parents influence adolescents' coping mechanisms for stress. Secure parent-child relationships are associated with the development of adaptive coping styles, which can lead to long-term positive outcomes. In contrast, insecure relationships may result in maladaptive coping strategies that increase distress.
