How nonshared environmental factors come to correlate with heredity / Christopher R. BEAM in Development and Psychopathology, 34-1 (February 2022)

Longitudinal models rarely explain the processes that generate observed differences between genetically and socially related individuals. We propose that exchanges between individuals and their environments (i.e., phenotype?environment effects) can explain the emergence of observed differences over time. Phenotype?environment models, however, would require violation of the independence assumption of standard behavioral genetic models; that is, uncorrelated genetic and environmental factors. We review how specification of phenotype?environment effects contributes to understanding observed changes in genetic variability over time and longitudinal correlations among nonshared environmental factors. We then provide an example using 30 days of positive and negative affect scores from an all-female sample of twins. Results demonstrate that the phenotype?environment effects explain how heritability estimates fluctuate as well as how nonshared environmental factors persist over time. We discuss possible mechanisms underlying change in gene?environment correlation over time, the advantages and challenges of including gene?environment correlation in longitudinal twin models, and recommendations for future research.

Interpersonal motivations in adolescent rumination / Jane MENDLE in Development and Psychopathology, 38-3 (August 2026)  

Public ISBD [article]  inDevelopment and Psychopathology > 38-3 (August 2026) . - p.1087-1091 Titre : Interpersonal motivations in adolescent rumination Type de document : texte imprimé Auteurs : Jane MENDLE, Auteur Article en page(s) : p.1087-1091 Langues : Anglais (eng) Mots-clés : adolescence  depression  gender  internalizing  rumination Index. décimale : PER Périodiques Résumé : In the decades since Nolen-Hoeksema’s (1991) original work on response styles, research on rumination has flourished within psychological science. This literature often emphasizes the association of impaired problem-solving with rumination. Spikes in the prevalence of rumination coincide with the entry into adolescence, as youth become increasingly sensitive to social feedback and interpersonal relationships. This article introduces the idea that rumination represents a socially reinforced process in adolescent girls, who are particularly likely to engage in rumination and to find interpersonal stress aversive. In the event that relationships evoke distress, girls may be able to generate solutions through ruminative coping; however, they are unwilling to accept and enact these solutions when these solutions have the potential to be further socially disruptive. Although ruminative inaction may have grave consequences for the moods of youth, it maintains an interpersonal harmony that some youth may prioritize and, in the process, avoids changing a social milieu, angering or displeasing others, or generating unwanted social controversy or conflict. This serves as reinforcement for ruminative coping, creating the risk that rumination will become an entrenched habit with the potential to further erode mood over time.
