DePasquale, Carrie E.; Herzberg, Max P.; Gunnar, Megan R. – Child Development Perspectives, 2021
Recent research has suggested that the pubertal period provides an opportunity for recalibrating the stress-responsive systems in youth whose responses to stress have been altered by early adversity. Such recalibration may have cascading effects that affect brain and behavioral development. In this article, we consider a large, cross-species…

Gunnar, Megan R.; Kryzer, Erin; Van Ryzin, Mark J.; Phillips, Deborah A. – Developmental Psychology, 2011
Children of ages 3 to 4.5 years (N = 107; 45 boys, 62 girls) were studied twice, 6 months apart, to examine whether the cortisol rise in child care at Time 1 (T1) was associated with (a) changes in anxious, vigilant behavior from T1 to Time 2 (T2) and (b) higher internalizing symptoms at T2. Controlling for measures of home environment and child…

Tarullo, Amanda R.; Mliner, Shanna; Gunnar, Megan R. – Developmental Psychology, 2011
Associations between behavioral inhibition and activity of the hypothalamic-pituitary-adrenocortical (HPA) system, a stress-sensitive neuroendocrine system indexed by salivary cortisol, have varied widely across studies. In the current study, we examined the role of peer social experiences in moderating patterns of association between…

Dennis, Tracy A.; Buss, Kristin A.; Hastings, Paul D.; Bell, Martha Ann; Diaz, Anjolii; Adam, Emma K.; Miskovic, Vladimir; Schmidt, Louis A.; Feldman, Ruth; Katz, Lynn Fainsilber; Rigterink, Tami; Strang, Nicole M.; Hanson, Jamie L.; Pollak, Seth D.; Dahl, Ronald E.; Silk, Jennifer S.; Siegle, Greg J.; Beauchaine, Theodore P.; Cicchetti, Dante; Rogosch, Fred A.; Fox, Nathan A.; Kirwan, Michael; Reeb-Sutherland, Bethany; Gunnar, Megan R.; Obradovic, Jelena; Boyce, W. Thomas; Molenaar, Peter C. M.; Gates, Kathleen M. – Monographs of the Society for Research in Child Development, 2012
In the past decade, there has been a dramatic growth in research examining the development of emotion from a physiological perspective. However, this widespread use of physiological measures to study emotional development coexists with relatively few guiding principles, thus reducing opportunities to move the field forward in innovative ways. The…

Gunnar, Megan R. – Monographs of the Society for Research in Child Development, 2010
This monograph provides critical insights into identifying which threads to pull in the "web of causation" to discern the impact of adverse early life experiences, and it provides guidance regarding how to identify patterns of behavior that are likely to reflect the impact of such experiences. In this article, the author offers her…

Gunnar, Megan R. – Child Development, 1987
This introduction to a special section on psychobiological studies of stress and coping discusses the problems of interpreting and integrating information on stress reactivity derived from a combination of behavioral and physiological measures. (PCB)

Kertes, Darlene A.; Gunnar, Megan R. – Child Development, 2004
The relation among children's evening activities, behavioral characteristics, and activity of the hypothalamic-pituitary-adrenocortical axis was assessed in normally developing children ages 7 to 10 years. Salivary cortisol at bedtime was compared on evenings when children had structured activities outside of the home with unstructured evenings at…

Gunnar, Megan R.; Donzella, Bonny – Child Development, 2004
Tympanic membrane (TM) temperature asymmetry has been proposed as a phenotypic marker of vulnerability to negative emotionality in children. Little is known about the stability of TM temperatures or how readily one can obtain a reliable index of the phenotype. TM temperatures were collected from 3- to 5-year-old children (N=73) over 5 months…
