Associations Between Maternal Cumulative Psychological Distress and Child Subsequent Social Competence
Maternal psychological distress may have adverse effects on child socioemotional development. However, supportive social networks and participation in out‐of‐home childcare may serve as key protective factors and promote positive developmental outcomes. This study investigated whether maternal cumulative psychological distress is associated with children's ( n = 528) social competence at the age of 5 years ( M = 5.02, SD = 0.08) in Finland. Laten…
The Moderating Role of Child Temperament in the Face of Parental Distress During Covid-19
This preregistered study examined whether child temperament predicts social-emotional functioning and moderates the associations between parental distress, COVID-19–related stressors, and children’s social-emotional outcomes during the pandemic. The participants were 1,305 Finnish children (46% girls) from the FinnBrain Birth Cohort, with temperament assessed at age 2.5 years and follow-ups conducted from ages 5 to 9 years. Across five time point…
Child inhibitory control in toddlerhood
Childhood inhibitory control (IC) is a key precursor of later social development, yet the mechanisms through which IC contributes to emerging interaction skills in toddlerhood remain insufficiently understood. We explored the cross-sectional associations between child IC and child interaction skills (responsiveness and involvement) with the mother at 30 months (N = 350) and conducted an exploratory longitudinal analysis of IC at 24 months and chi…
Maternal Emotional Availability Supports Child Communicative Development Regardless of Child Temperament—Findings From the FinnBrain Birth Cohort Study
The interplay of emotional availability (EA) and child temperament in association with early language development is understudied. We explored associations between maternal EA and infant communicative development and possible moderations by child temperament. Participants were 151 mother‐child dyads from the FinnBrain Birth Cohort Study. Path models of associations between 8‐month maternal EA and 14‐month communicative development and moderation …
Prenatal exposure to perfluoroalkyl substances predicts multimodal brain structural and functional outcomes in children aged 5 years

Reciprocal relationships between a child’s engagement with faces and mother–child interaction at 8, 30, and 60 months
Prioritized attention to faces can be viewed as an early-developing marker of social engagement. This behavior is closely linked with early interactions, but there has been little research examining the longitudinal associations between social engagement and parent-child interaction. We examined the reciprocal relations between mother-child interaction and child engagement with faces from infancy to preschool age. Participants of this study were …
Childcare context and socio-emotional development in toddlers – a quantitative report from the FinnBrain Birth Cohort Study, Finland
Toddlerhood is a period of intensive and rapid socio-emotional development. The effects of different types of childcare settings on child development have been widely studied, but the results have often been contradictory. The aim of this study was to compare social competence and socio-emotional problems in two-year-old children (n = 1104; girls 47.2%) who were either participating in out-of-home, center-based childcare or were cared for at home…
Mother–Infant Interaction and Maternal Postnatal Psychological Distress Associate with Child’s Social-Emotional Development During Early Childhood
We studied the effects of mother-infant interaction and maternal pre- and postnatal psychological distress on children's social-emotional problems and competences, as well as whether interaction quality moderates the association between distress and children's outcomes. Maternal pre- and postnatal psychological distress were measured using the SCL and EPDS questionnaires, whereas mother-infant interaction was measured when the child was 8 months …
Associations between observed and reported infant negative affectivity, fear and self‐regulation, and early communicative development—Evidence from the FinnBrain Birth Cohort Study
Self‐regulation and language are intertwined abilities, but the nature of their relations in early childhood when both skills are still emerging is insufficiently understood. Our knowledge of the relations between early negative affectivity and preverbal and verbal communicative development is still limited. Further, observed and reported temperament capture how aspects of temperament operate in different settings but are rarely used in parallel …
Spillover effects of the Covid-19 pandemic on attitudes to influenza and childhood vaccines
The current study sought to determine whether public perceptions of other vaccines and diseases than COVID-19 have been impacted by the COVID-19 pandemic. We longitudinally examined whether there had been a change from before the COVID-19 pandemic to during the pandemic in: (a) influenza vaccination behaviour and intentions; (b) the perceived benefit of childhood vaccines and influenza vaccines; (c) the perceived safety of childhood vaccines and …
Attention biases for emotional facial expressions during a free viewing task increase between 2.5 and 5 years of age
The normative, developmental changes in affect-biased attention during the preschool years are largely unknown. To investigate the attention bias for emotional versus neutral faces, an eye-tracking measurement and free viewing of paired pictures of facial expressions (i.e., happy, fearful, sad, or angry faces) and nonface pictures with neutral faces were conducted with 367 children participating in a Finnish cohort study at the age of 2.5 years a…
Individual differences in pupil dilation to others’ emotional and neutral eyes with varying pupil sizes
Sensitivity to others’ emotional signals is an important factor for social interaction. While many studies of emotional reactivity focus on facial emotional expressions, signals such as pupil dilation which can indicate arousal, may also affect observers. For example, observers’ pupils dilate when viewing someone with dilated pupils, so-called pupillary contagion. Yet it is unclear how pupil size and emotional expression interact as signals. Furt…
Alexithymic traits and parental postpartum bonding
In the postpartum period, some parents experience problems in bonding with the infant, which can lead to difficulties in adjusting to the parental caregiving role. Alexithymia, through deficits in emotional processing, could potentially be associated with problems in parental postpartum bonding. In the current study, this association has been explored in a large population‐based sample of mothers and fathers, and to our knowledge, this is the fir…
The stability of early developing attentional bias for faces and fear from 8 to 30 and 60 months in the FinnBrain Birth Cohort Study
Most infants exhibit an attentional bias for faces and fearful facial expressions. These biases reduce toward the third year of life, but little is known about the development of the biases beyond early childhood. We used the same methodology longitudinally to assess attention disengagement patterns from nonface control pictures and faces (neutral, happy, and fearful expressions) in a large sample of children at 8, 30, and 60 months ( N = 389/393…
Fearing the disease or the vaccine
As studies indicate that people perceive COVID-19 as a threatening disease, the demand for a vaccine against the disease could be expected to be high. Vaccine safety concerns might nevertheless outweigh the perceived disease risks when an individual decides whether or not to accept the vaccine. We investigated the role of perceived risk of COVID-19 (i.e., perceived likelihood of infection, perceived disease severity, and disease-related worry) an…
Behavioral Regulatory Problems Are Associated With a Lower Attentional Bias to Fearful Faces During Infancy
To investigate the role of early regulatory problems (RP), such as problems in feeding, sleeping, and calming down during later development, the association between parent-reported RP at 3 months (no-RP, n = 110; RP, n = 66) and attention to emotional faces at 8 months was studied. Eight-month-old infants had a strong tendency to look at faces and to specifically fearful faces, and the individual variance in this tendency was assessed with eye tr…
Child Temperament and Total Diurnal Cortisol in Out-of-Home Center-Based Child Care and in At-Home Parental Care
The association between child temperament characteristics and total diurnal saliva cortisol in 84 children (M = 2.3 years, SD = 0.6) attending out-of-home, center-based child care and 79 children (M = 2.0 years, SD = 0.5) attending at-home parental care was examined. Saliva samples were collected during two consecutive days, that is, Sunday and Monday, with four samples taken per day. While children higher in surgency had higher total diurnal cor…
Associations between maternal socioeconomic, psychosocial and seasonal factors, infant characteristics and human milk cortisol concentrations
OBJECTIVES: Glucocorticoids are one component of human milk (HM) potentially affecting offspring development. Previous studies have identified various maternal, obstetric and socioeconomic characteristics that are associated with HM cortisol concentration but the literature is still scarce concerning these determinants in human populations. We aimed to identify which factors are linked with HM cortisol concentration at 2 months postpartum. METHOD…
Maternal Depressive Symptoms During the Pre- and Postnatal Periods and Infant Attention to Emotional Faces
We examined how infants’ attentional disengagement from happy, fearful, neutral, and phase-scrambled faces at 8 months, as assessed by eye tracking, is associated with trajectories of maternal depressive symptoms from early pregnancy to 6 months postpartum (decreasing n = 48, increasing n = 34, and consistently low symptom levels n = 280). The sample (mother–infant dyads belonging to a larger FinnBrain Birth Cohort Study) was collected between 5/…
Latent Structure of Executive Functioning/Learning Tasks in the CogState Computerized Battery
This study tested whether executive functioning (EF)/learning tasks from the CogState computerized test battery show a unitary latent structure. This information is important for the construction of composite measures on these tasks for applied research purposes. Based on earlier factor analytic research, we identified five CogState tasks that have been labeled as EF/learning tasks and examined their intercorrelations in a new sample of Finnish b…
Educational differences in prenatal anxiety and depressive symptoms and the role of childhood circumstances
Despite interest in unequal maternal and child health, previous research has not focused on educational differences in anxiety and depressive symptoms during pregnancy, although they threaten maternal and child wellbeing. Using the prospective FinnBrain Cohort Study data on 2763 pregnant women over the three pregnancy trimesters and Finnish register data, we estimated multilevel regressions to describe educational differences in prenatal anxiety …
Alexithymic Traits and Hair Cortisol Concentrations in Pregnant Women
Alexithymia, and especially its dimension DIF, were associated with higher HCC and, therefore, may be linked to increased chronic physiological stress. Implications for pregnancy outcomes and infant development are discussed
Infant fecal microbiota composition and attention to emotional faces
The gut microbiota has been suggested to influence neurodevelopment in rodents. Preliminary human studies have associated fecal microbiota composition with features of emotional and cognitive development as well as differences in thalamus-amygdala connectivity. Currently, microbiota-gut-brain axis studies cover heterogenous set of infant and child brain developmental phenotypes, while microbiota associations with more fine-grained aspects of brai…
Investigating the effects of perinatal status and gender on adults’ responses to infant and adult facial emotion
The perception of emotion in infant faces is a key parental skill, thought to be impacted by caregiving experience. It is widely assumed that women, and in particular mothers in the postnatal period, are more attuned to infant facial expressions than men. However, empirical evidence for this is lacking, and it is not yet clear whether potential differences in emotion processing between adults during pregnancy and postnatally are specific to infan…
Infant Sex Moderates the Effects of Maternal Pre‐ and Postnatal Stress on Executive Functioning at 8 Months of Age
Previous studies report that early life stress, including maternal pre‐ and postnatal stress, has adverse effects on cognitive development and that these associations might be sex‐specific. However, no studies exist on early life stress and infant executive functioning ( EF ). The aim of this study was to examine the relationship between maternal pre‐ and postnatal stress and infant EF , and whether these associations are moderated by infant sex.…
The Prenatal Parental Reflective Functioning Questionnaire
Parental reflective functioning (PRF) is the capacity to focus on experience and feelings in oneself and in the child. Individual differences in PRF reportedly affect child attachment and socioemotional development. In this study, we report work on developing a questionnaire to assess PRF during pregnancy (Prenatal Parental Reflective Functioning Questionnaire; P-PRFQ). The factor structure of the 33-item version of the P-PRFQ was explored using …
