Neither environmental unpredictability nor harshness predict reliance on alloparental care among families in Cebu, Philippines / Stacy ROSENBAUM in Development and Psychopathology, 34-2 (May 2022)
[article]
Titre : Neither environmental unpredictability nor harshness predict reliance on alloparental care among families in Cebu, Philippines Type de document : Texte imprimé et/ou numérique Auteurs : Stacy ROSENBAUM, Auteur ; Christopher W. KUZAWA, Auteur ; Thomas W. MCDADE, Auteur ; Sonny Agustin BECHAYDA, Auteur ; Lee T. GETTLER, Auteur Article en page(s) : 743-754 Langues : Anglais (eng) Mots-clés : cooperative care behavioral ecology developmental plasticity life history theory Index. décimale : PER Périodiques Résumé : Alloparental caregiving is key to humans? highly flexible reproductive strategies. Across species and across societies, alloparental care is more common in harsh and/or unpredictable environments (HUEs). Currently, however, it is unclear whether HUEs predict intra-population variation in alloparental care, or whether early life HUEs might predict later alloparental care use in adulthood, consistent with adaptive developmental plasticity. We test whether harshness measures (socioeconomic status (SES), environmental hygiene, crowding) and unpredictability measures (parental unemployment, paternal absence, household moves) predicted how much alloparental assistance families in Cebu, Philippines received, in a multigenerational study with data collected across four decades. Though worse environmental hygiene predicted more concurrent alloparental care in 1994, we found little evidence that HUEs predict within-population variation in alloparental care in this large-scale, industrialized society. Indeed, less-crowded conditions and higher SES predicted more alloparental care, not less, in the 1980s and in 2014 respectively, while paternal absence in middle childhood predicted less reliance on alloparental care in adulthood. In this cultural context, our results generally do not provide support for the translation of interspecific or intersocietal patterns linking HUEs and alloparental care to intra-population variation in alloparental care, nor for the idea that a reproductive strategy emphasizing alloparental care use may be preceded by early life HUEs.

Titre : Why and how does early adversity influence development? Toward an integrated model of dimensions of environmental experience Type de document : Texte imprimé et/ou numérique Auteurs : Bruce J. ELLIS, Auteur ; Margaret A. SHERIDAN, Auteur ; Jay BELSKY, Auteur ; Katie A. MCLAUGHLIN, Auteur Article en page(s) : 447-471 Langues : Anglais (eng) Mots-clés : adversity dimensions brain plasticity developmental plasticity early adversity life history theory Index. décimale : PER Périodiques Résumé : Two extant frameworks ? the harshness-unpredictability model and the threat-deprivation model ? attempt to explain which dimensions of adversity have distinct influences on development. These models address, respectively, why, based on a history of natural selection, development operates the way it does across a range of environmental contexts, and how the neural mechanisms that underlie plasticity and learning in response to environmental experiences influence brain development. Building on these frameworks, we advance an integrated model of dimensions of environmental experience, focusing on threat-based forms of harshness, deprivation-based forms of harshness, and environmental unpredictability. This integrated model makes clear that the why and the how of development are inextricable and, together, essential to understanding which dimensions of the environment matter. Core integrative concepts include the directedness of learning, multiple levels of developmental adaptation to the environment, and tradeoffs between adaptive and maladaptive developmental responses to adversity. The integrated model proposes that proximal and distal cues to threat-based and deprivation-based forms of harshness, as well as unpredictability in those cues, calibrate development to both immediate rearing environments and broader ecological contexts, current and future. We highlight actionable directions for research needed to investigate the integrated model and advance understanding of dimensions of environmental experience.

Titre : Commentary: Beyond stressful life events and depression? – reflections on Bogdan et al. () Type de document : Texte imprimé et/ou numérique Auteurs : Jay BELSKY, Auteur Article en page(s) : p.458-459 Mots-clés : Gene–environment interactions stressful life events 5-HTTLPR early childhood developmental plasticity depression Index. décimale : PER Périodiques Résumé : In light of continuing disagreement, even at the meta-analytic level, as to whether the gene- × -environment (G×E) interaction involving 5-HTTLPR and stressful life events (SLEs) predicts depression, Bogdan and associates (this issue, Bogdan et al., 2014) sought to extend research on what has become a highly controversial general (GxE) and specific (5HTTLPR X SLEs) arena of inquiry. Thus, rather than seeking to replicate this specific GXE interaction in another sample of adolescents or adults, these investigators shifted the developmental focus–to very young children, aged 3-5 years of age. This re-direction was motivated by the kindling hypothesis which stipulates that the earliest episodes of depression might be especially sensitive to environmental adversity, with later episodes very much dependent on earlier ones and less a function of later-life environmental provocation. Thus, the investigators reasoned that the controversial G×E interaction might actually prove more evident and exert a more pronounced impact early in childhood than at older ages where they have been so extensively studied.
