Shared pleasure refers to moments where caregiver and infant engage in mutual smiling while making eye contact. This study examined shared pleasure in early mother-infant interactions as a predictor of infant attachment security. Associations between shared pleasure and maternal depressive symptoms were also investigated. The sample included 67 mother-infant dyads, of whom 22 mothers were diagnosed with postpartum depression. Shared pleasure was assessed through micro-coding of 3-min mother-infant interactions recorded in the laboratory at 4 months. Infant attachment security was measured using the Strange Situation Procedure at 13 months. Generalized linear models showed that the mean duration of shared pleasure moments, but not their mere presence, was associated with infant attachment security, with a medium-sized effect. Maternal depressive symptoms were not associated with shared pleasure. These findings suggest that shared pleasure may be an important early interaction dynamic to foster the development of secure attachment relationships.</p>\u0000 </div>","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145953539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research demonstrates that video chat may support family connections, especially with grandparents and other family members separated by physical location. However, video chat interactions also place significant socio-cognitive demands on infants that may impact the frequency and variety of family play. The present study examines predictors of intergenerational virtual play compared to in-person play. We conducted an OSF pre-registered secondary analysis of data from a longitudinal study of 47 infant-parent-grandparent triads who recorded up to three naturalistic Zoom video chats and a session when they met in person. All instances of attempted infant-grandparent play were coded for playful activity type (e.g., dancing, hide &amp; seek), duration, and whether the infant was successfully engaged in play (e.g., responded by smiling, vocalizing or imitating). Descriptive analyses revealed variability in play between families and across sessions. To capture the variety of ways in which grandparents, parents and infants played together, we fit growth models to predict the frequency of play bouts, the number of different types of playful activities observed (play repertoire), the proportion of time engaged in play, the proportion of play bouts for which infants were positively engaged, and the proportion of play bouts initiated by infants during video chat sessions. Across analyses, age was the strongest predictor of infant play on video chat. We then compared video chat play to play during the in-person session and found that play repertoire was significantly greater on video chat than in person. This study highlights the potential of digital tools to enhance intergenerational family relationships and social interactions through play. Video chat may serve as a high-quality supplemental activity for separated families.</p>","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12790811/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145953599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper is a version of the Presidential Address I gave in 2024 to the International Congress on Infant Studies in Glasgow. The address focused on convergence, defined as the replication of core findings across multiple methodological approaches, using examples drawn from family media ecology. The CAFE consortium is provided as an illustration of a global collaboration which created more precise measures of family media ecology and measured more diverse populations. The Dynamic Relational Ecological Approach to Media Effects Researcher (DREAMER) framework shaped the discussion from the role of individual child factors to broader structural factors. Converging findings on infant cognitive constraints on learning from media via the transfer deficit were discussed. Then both amelioration of the transfer deficit via joint engagement and exacerbation of negative outcomes due to technoference demonstrated the dynamic and relational nature of family media ecology. Structural factors, such as the COVID pandemic, drastically changed family media ecology globally. For some digital inequity led to underconnectivity and poorer outcomes and for others digital connection via videochat supported infant outcomes. Taken together the review concluded that multiple converging evidence-based findings are needed to tackle complex problems like growing up the digital age.</p>","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12732594/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145821690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated relations between sitting status (whether infants have achieved a sitting milestone), sitting age (amount of time before or after that milestone), and everyday positioning experience. Forty-three infants participated at 4, 5, 6, and/or 7 months of chronological age. Everyday experience was measured using Ecological Momentary Assessment: Caregivers reported infants' current position repeatedly throughout their daily activities. The best predictors of everyday sitting experience (proportion of responses in which the infant was in an unrestrained sitting position) were chronological age and overall sitting age, calculated from the first day infants sat using hands for support; hands-free sitting age, calculated from the first day infants sat without hands, did not uniquely contribute. Sitting experience supplanted supine experience, which decreased with overall sitting age; the effect of overall sitting age on prone experience varied with chronological age. Time restrained by an adult decreased only with chronological age, and time restrained by a device was not related to chronological or sitting age.

We explored the value systems underlying individual differences in parents' cognitions about their infants' sleep, including whether there were gender differences in parents' values. We examined whether those values directly related to their own parenting behaviors and interactions with their infants, and whether those values subsequently related to the quality of their infants' sleep. 1685 parents of infants (3–18 months) participated in an online survey on values and parenting-related choices and beliefs. Families used <i>Nanit</i>, a video baby monitoring system that uses computer vision technology to calculate nightly summary sleep characteristics (e.g., <i>quality</i> of night sleep, <i>parent visits</i>, <i>night wakings</i>). Value profiles depended on parent gender and were associated with cognitions about infant sleep and with parents' interactions with their infants, but were not associated with the quality of infants' sleep.

While previous research highlights the negative effects of parental media use on parenting and infant behavior, little is known about how maternal smartphone use affects both mothers' and infants' physiological and behavioral stress responses during early interactions. Consequently, we observed 67 mothers and their 6-month-old infants during an extended still-face paradigm including five phases in total: (1) an interaction baseline, (2) a still-face interruption, (3) a subsequent reunion, (4) a smartphone interruption, and (5) a subsequent reunion. The order of interruptions was randomized. Maternal and infant heart rates were continuously recorded via electrocardiogram. Infant protest and self-regulatory behaviors, as well as maternal co-regulatory behaviors, were coded from video recordings on a frame-by-frame basis. Infants showed significantly more protest behavior, higher cardiac arousal, and reduced parasympathetic activity during maternal smartphone use compared to baseline. During smartphone use, mothers reduced social engagement, accompanied by increased parasympathetic activity and decreased physiological arousal, which remained lower during reunions. We also found that dyadic physiological coupling emerged during still-face and smartphone disruptions, whereas dyadic behavioral coupling was observed only during the baseline interaction.
