Is there intergenerational continuity in early life experiences? Findings from the Harvard Study of Adult Development
Olivia Atherton et al.
Journal of Family Psychology, forthcoming
Abstract:
There has been longstanding and widespread interdisciplinary interest in understanding intergenerational processes, or the extent to which conditions repeat themselves across generations. However, due to the difficulty of collecting longitudinal, multigenerational data on early life conditions, less is known about the extent to which offspring experience the same early life conditions that their parents experienced in their own early lives. Using data from a socioeconomically diverse, White U.S. American cohort of 1,312 offspring (50% female) and their fathers (N = 518 families), we address three primary questions: (1) To what extent is there intergenerational continuity in early life experiences (social class, home atmosphere, parent–child relationship quality, health)? (2) Is intergenerational continuity in early life experiences greater for some domains of experience compared to others? and (3) Are there person-level (offspring sex, birth order, perceptions of marital stability) and family-level factors (family size, father education level and education mobility, marital stability) that moderate intergenerational continuity? Multilevel models indicated that intergenerational continuity was particularly robust for childhood social class, but nonsignificant for other early life experiences. Further, intergenerational continuity was moderated by several family-level factors, such that families with higher father education/mobility and marital stability, tended to have offspring with the most optimal early life experiences, regardless of what their father experienced in early life. We discuss the broader theoretical implications for family systems, as well as practical implications for individual-level and family-level interventions.
Gratitude improves parents’ well-being and family functioning

Emotion, forthcoming
Abstract:
Parents are inundated with suggestions to improve their relationships with their children and promote child development, but improving caregiver well-being is often overlooked despite being considered one of the most important methods to promote healthy child development. Drawing on the robust literature on the emotional and relationship benefits of gratitude, we present two studies demonstrating the advantages of gratitude for parents’ well-being and family functioning. First, in a 7-day daily experience study conducted in 2018 (N = 270), daily gratitude predicted greater well-being and family functioning, controlling for daily happiness, coder-rated care difficulty, and sociodemographics. Second, in a short-term longitudinal experiment conducted in 2018 (N = 619), participants were randomly assigned to write a gratitude letter or to complete a control activity. In this study, expressing gratitude predicted greater well-being and family functioning 1 week later via increases in positive emotions. Notably, across both studies neither felt nor expressed gratitude referred to one’s children; however, the results of our studies suggest that gratitude in general improves parent–child relationships and family well-being. This work provides insights regarding ways to improve parents’ well-being without requiring greater effort, energy, or attention to one’s children, and it suggests that promoting parents’ gratitude in general may benefit the entire family.
We've Got You Covered: Employer and Employee Responses to Dobbs v. Jackson
Pawel Adrjan et al.
University of Southern California Working Paper, August 2023
Abstract:
Following the June 24, 2022 Dobbs v. Jackson Supreme Court ruling, which overturned the federal right to abortion established in Roe v. Wade, hundreds of employers publicly announced policies covering out-of-state employee travel for abortions and related care. Leveraging data from Indeed and Glassdoor, we first document that companies with more female and more Democratic-leaning employees and executives were more likely to announce these policies. We then examine the causal impact such announcements had on recruitment, job satisfaction, and pay by introducing a new methodology to recover similar employers who did not make announcements using workers’ revealed preferences in job search. Difference-in-differences estimates reveal that for announcing companies: (i) vacancies received more job seeker interest, particularly in Democratic-leaning states and female-dominated jobs in states with “trigger” laws that outlawed abortion, (ii) satisfaction with management fell amongst existing employees, particularly in male-dominated jobs, and (iii) posted wages increased, especially for companies where employee sentiment declined. These results highlight the complicated trade-off employers face from engaging in sociopolitical dialogue, in particular how signals of company culture can help recruit new workers but alienate current ones.
Temperature and Maltreatment of Young Children
Mary Evans, Ludovica Gazze & Jessamyn Schaller
NBER Working Paper, August 2023
Abstract:
We estimate the impacts of temperature on alleged and substantiated child maltreatment among young children using administrative data from state child protective service agencies. Leveraging short-term weather variation, we find increases in maltreatment of young children during hot periods. We rule out that our results are solely due to changes in reporting. Additional analysis identifies neglect as the temperature-sensitive maltreatment type, and we do not find evidence that adaptation via air conditioning mitigates this relationship. Given that climate change will increase exposure to extreme temperatures, our findings speak to additional costs of climate change among the most vulnerable.
Preliminary Evidence for Genetic Nurture in Depression and Neuroticism Through Polygenic Scores
Justin Tubbs & Pak Sham
JAMA Psychiatry, August 2023, Pages 832-841
Design, Setting, and Participants: This cross-sectional study jointly modeled parental and offspring polygenic scores (PGSs) across 9 traits to test for the association of genetic nurture with lifetime broad depression and neuroticism using data from nuclear families in the UK Biobank, with data collected between 2006 and 2019. A broad depression phenotype was measured in 38 702 offspring from 20 905 independent nuclear families, with most of these participants also reporting neuroticism scores. Parental genotypes were imputed from sibships or parent-offspring duos and used to calculate parental PGSs. Data were analyzed between March 2021 and January 2023.
Results: This study of 38 702 offspring with data on broad depression (mean [SD] age, 55.5 [8.2] years at study entry; 58% female) found limited preliminary evidence for a statistically significant association of genetic nurture with lifetime depression and neuroticism in adults. The estimated regression coefficient of the parental depression PGS on offspring neuroticism (β = 0.04, SE = 0.02, P = 6.63 × 10−3) was estimated to be approximately two-thirds (66%) that of the offspring’s depression PGS (β = 0.06, SE = 0.01, P = 6.13 × 10−11). Evidence for an association between parental cannabis use disorder PGS and offspring depression was also found (β = 0.08, SE = 0.03, P = .02), which was estimated to be 2 times greater than the association between the offspring’s cannabis use disorder PGS and their own depression status (β = 0.04, SE = 0.02, P = .07).
Crocodile perception of distress in hominid baby cries
Julie Thévenet et al.
Proceedings of the Royal Society: Biological Sciences, 9 August 2023
Abstract:
It is generally argued that distress vocalizations, a common modality for alerting conspecifics across a wide range of terrestrial vertebrates, share acoustic features that allow heterospecific communication. Yet studies suggest that the acoustic traits used to decode distress may vary between species, leading to decoding errors. Here we found through playback experiments that Nile crocodiles are attracted to infant hominid cries (bonobo, chimpanzee and human), and that the intensity of crocodile response depends critically on a set of specific acoustic features (mainly deterministic chaos, harmonicity and spectral prominences). Our results suggest that crocodiles are sensitive to the degree of distress encoded in the vocalizations of phylogenetically very distant vertebrates. A comparison of these results with those obtained with human subjects confronted with the same stimuli further indicates that crocodiles and humans use different acoustic criteria to assess the distress encoded in infant cries. Interestingly, the acoustic features driving crocodile reaction are likely to be more reliable markers of distress than those used by humans. These results highlight that the acoustic features encoding information in vertebrate sound signals are not necessarily identical across species.
