I'm excited about this finding because babies grow up in complex relational ecosystems of multiple familial and non-familial caregivers. Real-time consistency *between* those caregivers is probably playing an important role in development, which we completely miss when we narrowly focus on dyads.

Ultimately even with a logistic model controlling for the individual sensitivity of both parent & grandparent, child age, & affective state in the prior block, we found that mutual sensitivity predicted infant affective state at the 30s level (p < .001). No significant findings in JVA model.
Hypothesis 2: mutual sensitivity predicts infant across-screen JVA In our JVA model we tested the relationship between mutual sensitivity and infant joint attention with their across-screen conversational partner, controlling for infant age. Here, we hypothesize that greater mutual sensitivity will be associated with a greater likelihood of successful infant engagement in across-screen joint visual attention. The image below depicts an infant’s bid for attention to the dog on the grandparent’s side of the screen, an example of across-screen JVA> Results H1: Mutual sensitivity predicts affective state Even after controlling for the individual sensitivity of each caregiver and child age, and after resolving issues of collinearity, mutual sensitivity significantly predicted infant affective state. (b = 0.78, p < .001). A 1-point increase in the distance between caregiver sensitivity was associated with a 22-percent decreased likelihood that the infant would be in the positive, alert affective state. Block order and the infant’s affective state in the preceding block were associated with infant affective state in the current block. H2: Mutual sensitivity predicts successful across-screen JVA When controlling for infant age, parent sensitivity, and grandparent sensitivity, mutual sensitivity was not significantly associated with successful across-screen JVA. link to the full paper in infancy: https://onlinelibrary.wiley.com/doi/10.1111/infa.70068

I've wanted to look at mutual sensitivity (consistency between caregivers in their sensitivity) for years, and this analysis was buoyed by encouragement at @affectscience.bsky.social 2023 after a flash talk exploring the method. Thanks to @tomhollenstein.bsky.social for state space inspiration!
What is mutual sensitivity between two caregivers? A growing body of research suggests that consistency in the caregiving environment predicts adaptive child development (see Ugarte & Hastings, 2023). Most studies have focused on consistency within a single caregiver over time. However, children do not grow up in isolated parent-child dyads. Is real-time consistency across two caregivers uniquely predictive of infant affective state (H1) and joint visual attention (H2)? This figure depicts real-time state spaces combining parent and grandparent sensitivity over three sessions within one family. Our mutual sensitivity variable was calculated by taking the square root of the distance between parent and grandparent. Eg., a distance of 0 meant the two caregivers shared a sensitivity score within a thirty second block. Importantly, our mutual sensitivity measure was agnostic to the degree of sensitivity of either caregiver. We collected data during the COVID-19 pandemic, inviting families with infants who had grandparents at a distance to record three Zoom conversations between the infant (see ages below) and the grandparent. 43 families submitted 3 video chats; 4 submitted only 2. Our final models included 2741 30s affect blocks and 660 JVA observations in multilevel logistic regressions. Hypothesis 1: Mutual sensitivity predicts infant affective state Prior theories and studies have linked young children’s affective states with language development, attentional control, and joint attention, but findings diverge on the role of affective valence, and rarely combine both affective valence and behavioral arousal. We chose a theoretically and empirically driven multidimensional affective state characterized by neutral-to-positive valence (see Bloom, 1993; Kubicek & Emde, 2012; Laake and Bridgett, 2014) and low-medium arousal, hypothesizing that mutual sensitivity would predict whether or not infants occupied this state space, even after controlling for the individual sensitivity of each caregiver and child age. Each infant occupies a distinct landscape of states.

👀 New paper out in Infancy! Mutual Sensitivity Between Caregivers Predicts Infant Affective State... @dougpiper.bsky.social & I co-led this analysis with Gabrielle Strouse, @proflaurenmyers.bsky.social @drzosh.bsky.social @geotro.bsky.social and Rachel Barr onlinelibrary.wiley.com/doi/10.1111/...
Mutual Sensitivity Between Caregivers Predicts Infant Affective State During Video Chat published in Infancy Abstract Infancy is an extraordinary period of human development, in which babies turn sensory and environmental information into meaning in the cradle of their caregivers’ affective and attentional cues. Babies express what they are thinking and feeling through smiles and gazes long before they develop expressive language. Most developmental research focuses on mother-infant dyads within a controlled lab environment, despite the complexity of young children’s caregiving ecosystems, which range far beyond the mother-child dyad and include caregivers at a distance via technology like video chat. This study uses a novel state space approach to examine relations between the sensitivity of two caregivers — what we call “mutual sensitivity” — and infants’ real-time affective and attentional states during video chat sessions. How to read a state space (Hollenstein, 2013): This figure depicts a single infant’s affective states over three video chat sessions. Each grid square represents a unique affective state characterized by both valence (1-7, negative to positive) and arousal (1-7), high to low. For example, we can see that during the first video chat session, this infant briefly spent time in a high arousal, low valence state (distress). Background Caregiver sensitivity - a caregiver’s responsive, warm, temporally contingent engagement with an infant - has been robustly linked to children’s development across cognitive and affective domains. Prior studies have shown that global caregiver sensitivity predicts both infant affective valence and infant engagement in JVA during in-person interactions (Braungart-Rieker et al., 2001; Mason et al., 2019) and during video chat (Roche et al., 2022; Myers et al., 2024). In this study we used the Biringen et al., 2000 scale (1-9) and coded all behavioral variables every 30 seconds.

👀 Fantastic new review of disparate literature on stress & development across cog, emo and phys domains. "Early Life Stress Effects on Children's Biology, Behavior, & Health: Evidence, Mediators, Moderators, & Solutions"

@nicolebushphd.bsky.social @alliesullivan.bsky.social & Amanda Noroña-Zhou
Abstract: This review synthesizes and critiques research on early life adversity and stress effects on multidomain health outcomes in child samples to fill a gap in the literature that has largely focused on adults. Prioritizing evidence from meta-analytic and systematic reviews as well as findings from (quasi-)experimental or large prospective longitudinal studies, we integrate interdisciplinary findings to characterize patterns of evidence for stress associations with child outcomes, including mental, physical, and positive health; academic, social, and justice system–related domains; and intermediary phenotypes that may predict disease, including biomarkers. We note cohesive evidence for sensitive periods of susceptibility to stress exposure and describe key mediators and moderators of stress effects, especially family-level factors. Then we highlight interventions targeting malleable factors that hold promise for ameliorating the effects of stress on children. Leveraging a developmental lens, we conclude with field-wide limitations and propose future directions for stress and health research that centers child development.
