Adolescents experience profound neuroendocrine changes, including hormone “coupling” between cortisol, testosterone, and dehydroepiandrosterone.
We used Latent Profile Analyses to derive four profiles of infant temperament from 990 twins at 6 and 12 months of age using observed infant behavior. Parents reported on their own emotional experiences.
Peer victimization impacts 13% of adolescents worldwide (Currie et al. 2012). Despite its prevalence and associated adverse outcomes, global cognitive processes that could be affected by peer victimization have not been thoroughly investigated.
Using Discordant MZ Twins and Genome-wide Methylation Analyses to Identify Anxiety-relevant Genes – Three MZ (genetically identical) twin pairs were chosen to be clearly discordant for childhood cortisol levels and adolescent fMRI patterns in the amygdala that correlated with anxiety symptoms.
