Developing a neurobehavioral animal model of poverty: Drawing cross-species connections between environments of scarcity-adversity, parenting quality, and infant outcome / Rosemarie E. PERRY in Development and Psychopathology, 31-2 (May 2019)

Mechanisms by which poverty affects development, however, remain unclear. To explore one potential mechanism of poverty's impact on social–emotional and cognitive development, an experimental examination of a rodent model of scarcity-adversity was conducted and compared to results from a longitudinal study of human infants and families followed from birth (N = 1,292) who faced high levels of poverty-related scarcity-adversity. Cross-species results supported the hypothesis that altered caregiving is one pathway by which poverty adversely impacts development. Rodent mothers assigned to the scarcity-adversity condition exhibited decreased sensitive parenting and increased negative parenting relative to mothers assigned to the control condition. Furthermore, scarcity-adversity reared pups exhibited decreased developmental competence as indicated by disrupted nipple attachment, distress vocalization when in physical contact with an anesthetized mother, and reduced preference for maternal odor with corresponding changes in brain activation. Human results indicated that scarcity-adversity was inversely correlated with sensitive parenting and positively correlated with negative parenting, and that parenting fully mediated the association of poverty-related risk with infant indicators of developmental competence. Findings are discussed from the perspective of the usefulness of bidirectional–translational research to inform interventions for at-risk families.

Hidden dynamics of economic hardship: Characterizing economic unpredictability and its role on self-regulation in early childhood / Meriah L. DEJOSEPH in Development and Psychopathology, 38-2 (May 2026)  

Public ISBD [article]  inDevelopment and Psychopathology > 38-2 (May 2026) . - p.822-837 Titre : Hidden dynamics of economic hardship: Characterizing economic unpredictability and its role on self-regulation in early childhood Type de document : texte imprimé Auteurs : Meriah L. DEJOSEPH, Auteur ; Nicole WALASEK, Auteur ; Sihong LIU, Auteur ; Ethan S. YOUNG, Auteur ; Abbie RAIKES, Auteur ; Marcus WALDMAN, Auteur ; Willem E. FRANKENHUIS, Auteur ; Philip FISHER, Auteur Article en page(s) : p.822-837 Langues : Anglais (eng) Mots-clés : Economic hardship  early childhood  environmental unpredictability  self-regulation Index. décimale : PER Périodiques Résumé : Economic hardship is known to shape children’s self-regulation, yet little is understood about how fluctuations in hardship unfold over time and whether different patterns of unpredictability carry unique developmental consequences. Using a socioeconomically diverse sample, we tracked families’ subjective economic hardship across 15–36 monthly assessments and applied an environmental statistics framework to quantify four indices of unpredictability: changepoints in mean, changepoints in variance, coefficient of variation, and noise. PCA identified two distinct forms of economic unpredictability: one marked by frequent, unpredictable hardship, and another by infrequent but abrupt hardship. Economic unpredictability was disproportionately experienced by racially minoritized and lower-income families in our sample, reinforcing structural inequities in economic resources. Relations between these indices and caregiver-reported measures of family routines and day-to-day unpredictability were weak, suggesting wide heterogeneity in the ways families adapt to economic unpredictability. Leveraging propensity score methods, we isolated the effects of unpredictability from hardship severity, finding that both were associated with greater self-regulation challenges in early childhood, with the strongest effects for hardship severity. These findings underscore the importance of capturing economic hardship as a dynamic and multidimensional experience, with implications for policy efforts aimed at promoting stability in families’ access to resources over time.
