The expectant social mind: A systematic review of face processing during pregnancy and the effect of depression and anxiety

Affective cognition in response to infant stimuli in pregnant compared with non-pregnant women

Physiological, neurocognitive, and psychological changes facilitates adaptation to motherhood. This cross-sectional study aimed to examine differences between pregnant and non-pregnant women in affective cognitive and psychophysiological responses to infant stimuli. We hypothesized that pregnant women would display (I) reduced negative emotional reactivity and perception of distressed infant stimuli, (II) increased attention toward infants compared to adults, and (III) greater psychophysiological response to infant distress. The sample comprised 22 pregnant women (22-38 weeks gestation) and 18 non-pregnant nulliparous women. Four computerized tasks were administered to measure affective cognitive processing of infant stimuli, while recording facial expressions, electrodermal activity, and eye gazes. Results indicated that pregnant women exhibited fewer negative facial expressions, reported less frustration when exposed to distressed infant cries, and showed greater attention to emotional infant faces compared to non-pregnant women, but the differences did not remain statistically significant after correction for multiple comparisons. No differences were observed in psychophysiological responses. The findings indicate a possible pregnancy-mediated effect regarding the cognitive processing of infant stimuli, potentially as preparation for motherhood. Future research with larger samples and longitudinal design is needed to understand the predictors, timing, and plasticity of cognitive changes during pregnancy.

Neural reactivity to infant emotion cues during pregnancy: Associations with peripartum anxiety and depressive symptoms

BACKGROUND

Pregnancy is marked by physiological and psychosocial changes for women, and event-related potentials (ERP) are comfortable and safe for examining brain function across pregnancy. The late positive potential (LPP) ERP, a measure of allocated attention to emotional stimuli, may provide insight into associations between internalizing symptoms and neural processing of infant emotion cues, which may be particularly salient in this life stage.

METHODS

We developed a task to examine neural and behavioral responses to infant faces in pregnant women (N = 120, Mage=31.09, SD=4.81), the impact of auditory infant cries on the LPP to faces, and associations between the LPP and anxiety and depressive symptoms. Participants matched distressed, happy, and neutral infant faces and shapes as a comparison condition with interspersed auditory conditions (infant cry sounds vs. white noise) while electroencephalogram data were collected. Participants also completed self-report measures of anxiety and depressive symptoms.

RESULTS

Reaction time (RT) was faster for the infant cry vs. white noise condition and when matching shapes vs. infant faces. Depressive symptoms were associated with slower RTs to neutral infant faces. The LPP was enhanced overall to faces vs. shapes, but there was no main effect of auditory condition. Anxiety symptoms were associated with an enhanced LPP to infant distressed faces in the infant cry condition.

CONCLUSIONS

Results support these methods for measuring neural and behavioral responses to infant emotional cues in pregnancy and provide evidence that combinations of auditory and visual stimuli may be particularly useful for capturing emotional processes relevant to anxiety.

Preliminary evidence of an increased susceptibility to face pareidolia in postpartum women

As primates, we are hypersensitive to faces and face-like patterns in the visual environment, hence we often perceive illusory faces in otherwise inanimate objects, such as burnt pieces of toast and the surface of the moon. Although this phenomenon, known as face pareidolia, is a common experience, it is unknown whether our susceptibility to face pareidolia is static across our lifespan or what factors would cause it to change. Given the evidence that behaviour towards face stimuli is modulated by the neuropeptide oxytocin (OT), we reasoned that participants in stages of life associated with high levels of endogenous OT might be more susceptible to face pareidolia than participants in other stages of life. We tested this hypothesis by assessing pareidolia susceptibility in two groups of women; pregnant women (low endogenous OT) and postpartum women (high endogenous OT). We found evidence that postpartum women report seeing face pareidolia more easily than women who are currently pregnant. These data, collected online, suggest that our sensitivity to face-like patterns is not fixed and may change throughout adulthood, providing a crucial proof of concept that requires further research.

Prenatal environment and developmental trajectories: the intrauterine growth restriction

The prenatal environment is of fundamental importance for the fetus, as the fetus is particularly susceptible to environmental influences while in utero, and several prenatal adversities may constitute a risk factor for fetal growth and child development. Intrauterine growth restriction (IUGR) refers to a pregnancy complication involving the inadequate growth of the fetus in utero, with potential programming consequences on the children's brain-behavior development. In this narrative review we will discuss the most recent literature about IUGR children, including their development and their relationship with the prenatal and postnatal environment. In particular, as an attempt to an adaptive response to intrauterine changes, the brain development of IUGR fetuses follows abnormal developmental pathways, which likely has cascade effects on the future neurodevelopmental outcomes of the children. Cognitive and motor functions are in fact impaired, as well as IUGR children present, across studies, poor socio-emotional abilities and a greater risk for internalizing and externalizing behavior problems. The current work also highlights how the postnatal environment, and in particular parental care, has an important role in IUGR development, acting as a protective factor, or otherwise increasing their constitutional vulnerabilities. Overall, this narrative review has important implications for clinical practice, suggesting the need for long-term follow-up care with IUGR children and strategies supporting parent-child interactions as well.

Relationship between Antenatal Mental Health and Facial Emotion Recognition Bias for Children’s Faces among Pregnant Women

The importance of identification of facial emotion recognition (FER) bias for a child’s face has been reinforced from the perspective of risk screening for future peripartum mental health problems. We attempted to clarify the relationship of FER bias for children’s faces with antenatal depression and bonding failure among pregnant women, taking into consideration their broad social cognitive abilities and experience in child raising. This study had a cross-sectional design, and participants were women in their second trimester of pregnancy. Seventy-two participants were assessed by the Edinburgh Postnatal Depression Scale (EPDS), the Mother-to-Infant Bonding Questionnaire (MIBQ), and a series of social cognitive tests. FER bias for a child’s face was assessed by Baby Cue Cards (BCC), and a larger number of disengagement responses suggest greater sensitivity to a child’s disengagement facial expressions. In a regression analysis conducted using EPDS as the dependent variable, a larger number of disengagement responses to the BCC (β = 0.365, p = 0.001) and the primipara status (β = −0.263, p = 0.016) were found to significantly contribute to antenatal depressive symptoms. Also, more disengagement responses to the BCC also significantly contributed to bonding failure as measured by the MIBQ (β = 0.234, p = 0.048). Maternal sensitivity to the child’s disengagement cues was associated with antenatal depressive symptoms and bonding failure more than the other social cognitive variables. The effects of FER bias on postpartum mental health and abusive behavior needs to be clarified by further longitudinal studies.

Maternal childhood maltreatment and perinatal outcomes: A systematic review

BACKGROUND

Maternal childhood maltreatment (MCM) is linked to poor perinatal outcomes but the evidence base lacks cohesion. We explore the impact of MCM on four perinatal outcome domains: pregnancy and obstetric; maternal mental health; infant; and the quality of the care-giving environment. Mechanisms identified in the included studies are discussed in relation to the maternal programming hypothesis and directions for future research.

METHOD

We completed a comprehensive literature search of eight electronic databases. Independent quality assessments were conducted and PRISMA protocols applied to data extraction.

RESULTS

Inclusion criteria was met by N = 49 studies. MCM was consistently associated with difficulties in maternal and infant emotional regulation and with disturbances in the mother-infant relationship. Directly observed and maternal-reported difficulties in the mother-infant relationship were often mediated by mothers' current symptoms of psychopathology. Direct and mediated associations between MCM and adverse pregnancy and obstetric outcomes were suggested by a limited number of studies. Emotional and sexual abuse were the most consistent MCM subtype significantly associated with adverse perinatal outcomes.

LIMITATIONS

A meta-analysis was not possible due to inconsistent reporting and the generally small number of studies for most perinatal outcomes.

CONCLUSIONS

MCM is associated with adverse perinatal outcomes for mothers' and infants. Evidence suggests these associations are mediated by disruptions to maternal emotional functioning. Future research should explore biological and psychosocial mechanisms underpinning observed associations between specific subtypes of MCM and adverse perinatal outcomes. Services have a unique opportunity to screen for MCM and detect women and infants at risk of adverse outcomes during the perinatal period.

Prenatal mother-father cortisol linkage predicts infant executive functions at 24 months

The present study investigated associations between prenatal mother-father cortisol linkage and infant executive functions. Data come from an international sample (N = 358) of predominantly white and middle- to upper-class first-time parents. During late pregnancy, parents collected diurnal salivary cortisol samples and reported on levels of psychological stress. At 24 months, children completed a battery of executive function tasks. Parent cortisol linkage was operationalized as the time-dependent, within-dyad association between maternal and paternal diurnal cortisol. Results indicated that prenatal linkage was positively related to infant executive functions, suggesting that stronger mother-father cortisol linkage was associated with higher executive function scores. Additionally, this relation was moderated by paternal average cortisol levels such that executive function scores were lower when fathers had higher average cortisol levels and linkage was weak. This association suggests that elevated paternal cortisol amplifies the negative relation between lower cortisol linkage and lower infant executive function scores. Importantly, these findings were observed while controlling for observational measures of caregiving and self-report measures of psychosocial functioning and infant social-emotional behavior. These results suggest that prenatal linkage of mother's and father's stress physiology plays a potentially important part in programming and regulating infant neurocognitive development.

The rewards of motherhood: Neural response to reward in pregnancy prospectively predicts maternal bonding with the infant in the postpartum period

Mother-to-infant attachment is critical to the health of mothers and offspring. While reward circuitry is implicated in maternal attachment, no studies have yet examined whether antenatal (i.e., in pregnancy) reward responsiveness predicts mother-to-infant bonding in the postnatal period. In a sample of 63 women, we examined whether the Reward Positivity (RewP), an event-related potential elicited to feedback indicating monetary reward, measured in pregnancy prospectively predicts self-reported mother-to-infant attachment at approximately one year postpartum. An increased antenatal RewP was associated with increased postnatal pleasure in proximity with the infant. Furthermore, this association was independent of associations with depression, anxiety, and stress symptoms. This is the first study to find a prospective association between reward responsiveness in pregnancy and postnatal bonding with the infant. Future directions for attachment research are discussed.

Maternal-fetal attachment in pregnant Italian women: multidimensional influences and the association with maternal caregiving in the infant's first year of life

Background

Maternal–Fetal Attachment (MFA) describes the cognitive-representational, emotional, and behavioral aspects of the mother–fetus relationship that develops during pregnancy.

We present two studies conducted on pregnant Italian women. In Study I, we aimed to explore multifaceted associations of MFA with variables important for a healthy pregnancy (e.g., maternal mental health, the couple’s relationship). In Study II, we investigated the predictive role of MFA on observed maternal caregiving during the first months of the infant’s life.

Methods

In Study I, 113 pregnant Italian women were assessed on MFA (Maternal Antenatal Attachment Scale, MAAS), maternal depression (Beck Depression Inventory-II, BDI-II), maternal anxiety (State Trait Anxiety Inventory – State version, STAI), adjustment of the couple (Dyadic Adjustment Scale, DAS), and perceived parental care (The Parental Bonding Instrument, PBI). In Study II, 29 mother–infant pairs were followed up at 4 months to assess observational variables of maternal caregiving through the Emotional Availability Scale (EAS) and to test for an association with MFA in pregnancy.

Results

Study I showed a significant association between MFA and the quality of the couple relationship (β = .49, P < .001) and between MFA and the recall of memories of care received in childhood (β = .22, P = .025). Study II showed a predictive effect of MFA on maternal structuring observed during mother–infant interactions at 4 months of age (β = 0.36, P = .046).

Conclusion

The study points out relevant relationship contexts that might receive care and support throughout pregnancy to protect MFA. The findings also provide thoughtful insights on the role of MFA in early maternal caregiving, suggesting that MFA might be a candidate as one putative antecedent of mother–infant interaction processes.

Emotional Infant Face Processing in Women With Major Depression and Expecting Parents With Depressive Symptoms

Processing of emotional facial expressions is of great importance in interpersonal relationships. Aberrant engagement with facial expressions, particularly an engagement with sad faces, loss of engagement with happy faces, and enhanced memory of sadness has been found in depression. Since most studies used adult faces, we here examined if such biases also occur in processing of infant faces in those with depression or depressive symptoms. In study 1, we recruited 25 inpatient women with major depression and 25 matched controls. In study 2, we extracted a sample of expecting parents from the NorBaby study, where 29 reported elevated levels of depressive symptoms, and 29 were matched controls. In both studies, we assessed attentional bias with a dot-probe task using happy, sad and neutral infant faces, and facial memory bias with a recognition task using happy, sad, angry, afraid, surprised, disgusted and neutral infant and adult faces. Participants also completed the Ruminative Responses Scale and Becks Depression Inventory-II. In study 1, we found no group difference in either attention to or memory accuracy for emotional infant faces. Neither attention nor recognition was associated with rumination. In study 2, we found that the group with depressive symptoms disengaged more slowly than healthy controls from sad infant faces, and this was related to rumination. The results place emphasis on the importance of emotional self-relevant material when examining cognitive processing in depression. Together, these studies demonstrate that a mood-congruent attentional bias to infant faces is present in expecting parents with depressive symptoms, but not in inpatients with Major Depression Disorder who do not have younger children.

Italia Ti Ascolto [Italy, I am listening]: an app-based group psychological intervention during the COVID-19 pandemic

The onset of the coronavirus disease 2019 (COVID-19) pandemic impacted individuals' psychological wellbeing resulting in heightened perceived stress, anxiety, and depression. However, a significant issue in accessing psychological care during a lockdown is the lack of access to in-person interventions. In this regard, research has shown the efficacy and utility of psychological app-based interventions. 'Italia Ti Ascolto' (ITA) has been developed as a population tailored internet-based intervention to offer an online professional solution for psychological support needs. The ITA app is available on iOS and Android systems. Users completed a baseline assessment on emotion regulation strategies (cognitive reappraisal and expressive suppression), psychological stress, anxiety, depression, and perceived social support. Participants could select among several one-hour long clinical groups held by expert psychotherapists. After every session, people were asked to complete a quick users' satisfaction survey. Our contribution presents ITA's intervention protocol and discusses preliminary data on psychological variables collected at baseline. Data showed significant associations between emotion regulation strategies, symptoms of depression and anxiety, and level of stress. Moreover, the role of perceived social support is considered. Future developments and implications for clinical practice and treatment are discussed.

All the Faces of Research on Borderline Personality Pathology: Drawing Future Trajectories through a Network and Cluster Analysis of the Literature

"Borderline Personality Disorder is a severe condition that affects self and interpersonal dimensions and emotional and behavioral regulation. Since the last decades of the 20th century, an impressive amount of research and clinical contributions on BPD came from specific fields such as psychiatry, clinical psychology, psychopharmacology, and, more recently, cognitive neuroscience. All contributions tackled the challenges of finding reliable diagnostic categories, highlighting detailed developmental trajectories, and fostering effective treatment protocols. However, as results come from different areas, it is often challenging to depict a coherent and yet multifaceted framework on this topic. In this study, we conducted a scientometric analysis of the available literature on BPD to provide a systematic and comprehensive overview of research on BPD and emphasize historical changes, intertwining between fields and new areas of investigation. Results clearly show the evolution of research on BPD starting from the initial development of the construct, passing through the studies on treatment efficacy, the results of longitudinal studies, the advances in cognitive neurosciences, and the recent dimensional conceptualization in DSM-5. Moreover, it emphasizes promising areas of investigation, such as the relations of BPD with NSSI, ADHD, and vulnerable features of narcissism."

Relationship between parenthood and cortical thickness in late adulthood

Pregnancy and the early postpartum period alter the structure of the brain; particularly in regions related to parental care. However, the enduring effects of this period on human brain structure and cognition in late life is unknown. Here we use magnetic resonance imaging to examine differences in cortical thickness related to parenthood in late life, for both sexes. In 235 healthy older women, we find a positive relationship between parity (number of children parented) and memory performance in mothers. Parity was also associated with differences in cortical thickness in women in the parahippocampus, precuneus, cuneus and pericalcarine sulcus. We also compared non-parents to parents of one child, in a sub-sample of older women (N = 45) and men (N = 35). For females, six regions differed in cortical thickness between parents and non-parents; these regions were consistent with those seen earlier in life in previous studies. For males, five regions differed in cortical thickness between parents and non-parents. We are first to reveal parenthood-related brain differences in late-life; our results are consistent with previously identified areas that are altered during pregnancy and the postpartum period. This study provides preliminary evidence to suggest that neural changes associated with early stages of parenthood persist into older age, and for women, may be related to marginally better cognitive outcomes.

Maternal prenatal depression, PTSD, and problematic parenting: the mediating role of maternal perceptions of infant emotion

Background: Perinatal illness is alarmingly common and has negative effects on maternal and infant well-being. Depression and posttraumatic stress disorder (PTSD), specifically, are characterised by negative views of the self and others, which may impact a mother's perceptions of herself and her child. Objective: This study examined the relationship between depression and PTSD symptoms, maternal perceptions of infant emotions, and parenting behaviours. Methods: 120 pregnant, mostly low-income women and their infants (after birth) participated in a longitudinal study. Maternal depression and PTSD symptoms were assessed during pregnancy and 1 year postpartum; maternal perceptions of infant emotions and parenting quality were assessed at 1 year. Results: Correlation analyses revealed significant, negative associations between prenatal (but not postnatal) psychiatric symptoms and positive perceptions of infant emotions, as well as between positive perceptions of infant emotions and negative parenting. Results also revealed significant indirect effects of prenatal depressive and PTSD symptoms on negative parenting via perceptions of infant emotion (95% CIs:.0013 -.0200 and.0008 -.0083, respectively). Conclusion: Findings highlight that mothers should be routinely screened for psychiatric symptoms during the perinatal period, and perceptions of infant emotions may be an important target for parent-infant mental health interventions.

Emotional Stress During Pregnancy - Associations With Maternal Anxiety Disorders, Infant Cortisol Reactivity, and Mother-Child Interaction at Pre-school Age

There is growing evidence that even milder forms of maternal stress or anxiety during pregnancy affect the fetus causing possible long-term consequences for infant and child development. The mechanisms through which prenatal maternal stress may affect the unborn are not yet entirely clarified. Due to limited self-regulatory skills after birth, infants depend on sensitive behavior of their parents to regulate affective states and physiological arousal. Dyadic affect regulation has been linked to various developmental patterns up to adolescence and thereby represents a key element of early social relationships. Aim of the study was to evaluate possible long-term consequences of emotional stress during pregnancy and postpartum anxiety disorders, as well as infant postpartum cortisol reactivity on mother–child-interaction at pre-school age. The sample comprised of N = 63 mother–infant dyads at study entry, n = 28 diagnosed with postpartum anxiety disorders according to the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV), n = 35 were healthy controls. Mothers were interviewed with the Structured Clinical Interview for DSM-IV Disorders at an average infant age of M = 4.1 months and filled out a questionnaire regarding emotional stress during pregnancy. Further, they were videotaped during the Face-to-Face-Still-Face paradigm (FFSF), a widely used mild socio-emotional stressor for infants. To determine infant stress-reactivity, infant salivary cortisol was collected before, immediately after and 20 min after the FFSF. Missing values were estimated by multiple imputations. At the age of M = 5.3 years, mother-child-interaction was re-assessed in a follow-up sample of n = 30 dyads via a free-play situation. Moreover, dimensional measures for anxiety were assessed. Mothers in the clinical group reported significantly higher stress scores than the control group. Infant stress reactivity in the early postpartum period and maternal anxiety symptoms at the 5-year follow-up assessment were significantly associated with dyadic interaction quality at pre-school age. Even though maternal stress during pregnancy did not directly predict mother–child interaction quality at pre-school age, it was significantly correlated with infant cortisol reactivity during postpartum period. Nevertheless, caution should be taken when interpreting the results considering the small sample size.
