Adverse childhood experiences (ACEs), or cumulative childhood stress exposures, such as abuse, neglect, and household dysfunction, predict later health problems in both the exposed individuals and their offspring. One potential explanation suggests exposure to early adversity predicts epigenetic modification, especially DNA methylation (DNAm), link...

Attachment is a motivational system promoting felt security to a caregiver resulting in a persistent internal working model of interpersonal behavior. Attachment styles are developed in early social environments and predict future health and development outcomes with potential biological signatures, such as epigenetic modifications like DNA methyla...

Background: There are significant sex differences in human physiology and disease; the genomic sources of these differences, however, are not well understood. During puberty, a drastic neuroendocrine shift signals physical changes resulting in robust sex differences in human physiology. Here, we explore how shifting patterns of DNA methylation may...

The stress response system is disrupted in individuals with major depressive disorder (MDD) as well as in those at elevated risk for developing MDD. We examined whether DNA methylation (DNAm) levels of CpG sites within HPA-axis genes predict the onset of MDD. Seventy-seven girls, approximately half (n = 37) of whom were at familial risk for MDD, we...

Experts explore the maturation of nonlinear brain dynamics from a developmental perspective and consider the relationship of neurodevelopmental disorders to early disruption in dynamic coordination. This volume in the Strüngmann Forum Reports series explores the complex mechanisms that accompany the dynamic processes by which the brain evolves and...

Soft touch possesses strong prosocial effects that facilitate social bonding and group cohesion in animals. Touch activates opioids (OP) and oxytocin (OXT), two neuromodulators involved in affiliative behaviors and social bonding. We examined whether touch serves as an unconditioned reward in affective conditioning of human faces, a basic process i...

Animal models of early postnatal mother–infant interactions have highlighted the importance of tactile contact for biobehavioral outcomes via the modification of DNA methylation (DNAm). The role of normative variation in contact in early human development has yet to be explored. In an effort to translate the animal work on tactile contact to humans...

The interplay of genetically-driven biological processes and environmental factors is a key driver of research questions spanning multiple areas of psychology. A nascent area of research focuses on the utility of epigenetic marks in capturing this intersection of genes and environment, as epigenetic mechanisms are both tightly linked to the genome...

Border and Keller argue that candidate gene approaches are outdated and out-of-touch with the current understanding of the genetic architecture of complex behavioral traits and should be abandoned in favor of unbiased, genome-wide approaches. Border and Keller further suggest that a candidate gene should not be selected for in-depth investigation u...

Puberty begins a period of vulnerability for disordered eating that is maintained and amplified through adolescence and early adulthood. In the present study, we test the association between young women's recollections of physical maturation and disordered eating outcomes in early adulthood. Participants comprised N = 421 female undergraduate stude...

Background: Standard models used to test gene-environment interaction (G × E) hypotheses make the causal assumption that there are no unobserved variables that could be biasing the interaction estimate. Whether this assumption can be met in nonexperimental studies is unclear because the interactive biological pathways from genetic polymorphisms an...

Sensitivity to environmental context has been of interest for many years, but the nature of individual differences in environmental sensitivity has become of particular focus over the past 2 decades. What is particularly uncertain are the neural variables and processes that mediate the effects of environment on developmental outcomes. Accordingly,...

In the current study, we tested for gene × environment interactions in the association between pubertal timing and adolescent depression by examining how socioeconomic factors might moderate age at menarche’s relation with depressive symptoms. Participants comprised 630 female twin and sibling pairs from the National Longitudinal Study of Adolescen...

Objective: Puberty is an important period of risk for the onset of eating pathology in adolescent females. This review focuses on changes in reproductive hormones during puberty as one specific psychopathogenic mechanism. Method: Studies of puberty and eating disorder-related phenotypes were identified using search databases and the reference se...

Neurobehavioral models of personality suggest that the salience assigned to particular classes of stimuli vary as a function of traits that reflect both the activity of neurobiological encoding and relevant social experience. In turn, this joint influence modulates the extent that salience influences attentional processes, and hence learning about...

Girls who experience earlier pubertal timing relative to peers also exhibit earlier timing of sexual intercourse and more unstable sexual relationships. Although pubertal development initiates feelings of physical desire, the transition into romantic and sexual relationships involves complex biological and social processes contributing both to phys...

Adolescent suicide is a major public health concern. Stressing the need for public health-based solutions, the Centers for Disease Control and Prevention identified "connectedness" as one means of pursuing this agenda. To advance this effort in suicide prevention with adolescents, (1) consistencies and variation in the literature overtly linking co...

Adolescent dating and sexual activity are consistently associated with risk for depression, yet the pathways underlying this association remain uncertain. Using data on 1,551 sibling pairs (ages 13-18) from the National Longitudinal Study of Adolescent Health, the current study utilized a sibling comparison design to assess whether adolescent datin...

Empirical research has recently addressed the real or personal relationship between patients and psychotherapists. The present study examined the interrelations of client attachment security, recollections of real relationship, and client attachment to therapist in a sample of 143 college students who had completed at least five sessions of previou...
