Past research shows that social networks get smaller with age. But not all types of relationships may shrink at the same rate or for similar reasons. In the present study, we used a unique data set from a sample of 235 men who were followed longitudinally for 71 years to examine how the general pattern of network shrinkage documented in previous research generalizes to the number of emotional support providers in people's networks.

There has been longstanding and widespread interdisciplinary interest in understanding intergenerational processes, or the extent to which conditions repeat themselves across generations. However, due to the difficulty of collecting longitudinal, multigenerational data on early life conditions, less is known about the extent to which offspring experience the same early life conditions that their parents experienced in their own early lives. Using data from a socioeconomically diverse, White U.

Objectives: Mindfulness has been linked to better emotion regulation and more adaptive responses to stress across a number of studies, but the mechanisms underlying these links remain to be fully understood. The present study examines links between trait mindfulness (Five Facets of Mindfulness Questionnaire; FFMQ) and participants' responses to common emotional challenges, focusing specifically on the roles of reduced avoidance and more self-distanced engagement as key potential mechanisms driving the adaptive benefits of trait mindfulness.

Methods: Adults ( = 305, age range: 40-72) from the Second Generation Study of the Harvard Study of Adult Development completed two laboratory-based challenges - public speaking combined with difficult math tasks (the Trier Social Stress Test) and writing about a memory of a difficult moment.

Unlabelled: Past research suggests that higher coherence between feelings and physiology under stress may confer regulatory advantages. Research and theory also suggest that higher resting vagal tone (rVT) may promote more adaptive responses to stress. The present study examines the roles of response system coherence (RSC; defined as the within-individual covariation between feelings and heart rate over time) and rVT in mediating the links between childhood adversity and later-life responses to acute stressors.

Previous measures of childhood adversity have enabled the identification of powerful links with later-life wellbeing. The challenge for the next generation of childhood adversity assessment is to better characterize those links through comprehensive, fine-grained measurement strategies. The expanded, retrospective measure of childhood adversity presented here leveraged analytic and theoretical advances to examine multiple domains of childhood adversity at both the microlevel of siblings and the macrolevel of families.

The current study examined whether reliance on more adaptive defense mechanisms throughout early adulthood may help explain previously documented relationships between childhood nurturance and better midlife functioning. Utilizing a unique longitudinal study, data were from age 18 through midlife (age 63) on 135 males. Childhood nurturance was assessed upon study entry and defense mechanism usage was assessed throughout earlier adulthood.

Aspects of social support during combat deployment, such as unit cohesion, have been shown to affect later posttraumatic stress disorder (PTSD) development among veterans. We utilized a longitudinal database to assess how relationship quality with fellow soldiers in World War II (WWII) might be linked with postwar PTSD symptoms. Data were available on 101 men who experienced combat exposure in WWII, documented through postwar assessment.

Objective: Identifying adaptive ways to cope with extreme stress is essential to promoting long-term health. Memory systems are highly sensitive to stress, and combat exposure during war has been shown to have deleterious effects on cognitive processes, such as memory, decades later. No studies have examined coping styles used by combat veterans and associations with later-life cognitive functioning.

Developmentally sensitive efforts to help students learn, practice, and regularly use mindfulness tactics easily and readily in and beyond the classroom are important to help them manage future stresses. Mindfulness emphasizes consciously focusing the mind in the present moment, purposefully, without judgment or attachment. Meditation extends this to setting aside time and places to practice mindfulness, and additionally, yoga includes physical postures and breathing techniques that enhance mindfulness and meditation.

Objective: Insufficient sleep in children is associated with adverse health effects. We examined the associations of early life risk factors with infant sleep duration.

Methods: We studied 1676 mother-infant pairs in a prebirth cohort study.
