An emerging body of literature suggests there is a relationship between a pregnant woman's psychological wellbeing and the development of maternal-fetal attachment (MFA) and early postpartum bonding. The nature of this relationship is not well understood because of the limited theoretical framework surrounding the construct of MFA and variations in study methods and data collection points. In this systematic review, we synthesize the published literature to determine the nature of the relationship from the antenatal to early postnatal period and to provide recommendations for future research and clinical practice. Using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) approach, four electronic databases were searched for peer-reviewed empirical studies, published in English. Articles were considered for inclusion if data was collected on at least one domain of maternal wellbeing/mental health and MFA during pregnancy or MFA during pregnancy and the mother-infant relationship during the early postpartum period (up to 12 weeks). No date parameters were applied to the search strategy. The review was registered with PROPSERO (registration number: CRD42018096174). 25 studies examining maternal mental health and MFA/postpartum bonding were selected for inclusion in this review. Key findings identified from the review were: a need to validate existing mental health measures or develop new measures specific for use in antenatal populations; inconsistencies in data collection points throughout pregnancy and postpartum; a lack of consensus about the construct of MFA and the way it is assessed; and a continued focus on postpartum outcomes. Scientific gaps remain in our understanding of the relationship between maternal mental health and both MFA and postpartum bonding which limit our theoretical understanding of the MFA construct. Recommendations for future research are to employ prospective longitudinal designs that span the full pregnancy and postpartum period, and for consistency in the terminology and methodology used when considering MFA. A re-focus of research attention on the theory behind MFA will allow a richer and more holistic account of the emerging relationship between mother and baby.

Significance The potential benefits of infant sleep for memory processing are largely unexplored. Here we show evidence that having an extended nap (≥30 min) within 4 h of learning helps 6- and 12-month-old infants to retain their memories for new behaviors across a 4- and 24-h delay. These results suggest that infants rely on frequent naps for the formation of long-term memories. Human infants devote the majority of their time to sleeping. However, very little is known about the role of sleep in early memory processing. Here we test 6- and 12-mo-old infants’ declarative memory for novel actions after a 4-h [Experiment (Exp.) 1] and 24-h delay (Exp. 2). Infants in a nap condition took an extended nap (≥30 min) within 4 h after learning, whereas infants in a no-nap condition did not. A comparison with age-matched control groups revealed that after both delays, only infants who had napped after learning remembered the target actions at the test. Additionally, after the 24-h delay, memory performance of infants in the nap condition was significantly higher than that of infants in the no-nap condition. This is the first experimental evidence to our knowledge for an enhancing role of sleep in the consolidation of declarative memories in the first year of life.

The widespread accessibility and use of the internet provides numerous opportunities for women to independently seek out pregnancy-related information and social and emotional support during the antenatal period. Given the heightened psychological vulnerability of the pregnancy period there is a critical need to examine digital media use within the context of the feelings that women have about themselves and towards their fetus. The current study examined the relationship between digital media use during pregnancy, psychological wellbeing and their maternal-fetal attachment using an online survey. Forty-eight pregnant women completed a self-report questionnaire on their reasons for using digital media, and standardised measures of self-criticism, negative affect, social quality of life (QOL), and maternal-fetal attachment. The mean age of participants was 29.4 years ( SD = 5.26), with a mean of 24.3 weeks gestation ( SD = 9.95). Information seeking, emotional support and social support were highly endorsed reasons for digital media use (85.42%, 66.67%, 62.5% respectively). However, digital media use was positively correlated with negative affect ( p = .003) and self-criticism ( p < .001). Digital media use was also negatively correlated with QOL ( p = .007). There was no evidence of a relationship between digital media use and maternal-fetal attachment ( p = .330). Digital environments may be an important social context within which a pregnant woman develops her own maternal identity and knowledge. There are a number of benefits and limitations of this medium for providing information and support for women during pregnancy. Enhancing the opportunities to promote pregnant women’s wellbeing in this context is an important avenue for further research and practice.

Experience plays a crucial role in the development of the face processing system. At 6 months of age infants can discriminate individual faces from their own and other races. By 9 months of age this ability to process other-race faces is typically lost, due to minimal experience with other-race faces, and vast exposure to own-race faces, for which infants come to manifest expertise [1]. This is known as the Other Race Effect. In the current study, we demonstrate that exposing Caucasian infants to Chinese faces through perceptual training via picture books for a total of one hour between 6 and 9 months allows Caucasian infants to maintain the ability to discriminate Chinese faces at 9 months of age. The development of the processing of face race can be modified by training, highlighting the importance of early experience in shaping the face representation.

Background Pregnancy is an important time for women’s mental health and marks the foundations of the emerging bond between mother and baby. This study aimed to investigate the role of pregnancy acceptability and intendedness in maternal mental health and bonding during pregnancy. Methods Data were collected from a community sample of 116 Australian pregnant women ( M  = 29.54, SD  = 5.31) through a series of self-report questionnaires pertaining to mental health and antenatal bonding. Results Lower pregnancy acceptability was correlated with higher depression, anxiety and total distress, lower physical and environmental quality of life and lower antenatal bonding. Women who reported their pregnancy was intended reported higher physical quality of life than those who reported their pregnancy was unintended. The relationship between total distress and antenatal bonding was moderated by women’s degree of pregnancy acceptability (low versus high). For women with low acceptability, higher distress was associated with lower bonding, but there was no such association for women with high pregnancy acceptability. The moderation model examining associations between distress and pregnancy acceptability explained 15% of the variance in antenatal bonding scores. Conclusion Consideration of women’s appraisal of their pregnancy acceptability may provide a valuable framework for identifying individuals who may be at risk for mental health and bonding difficulties.

Associative learning is a key feature of adaptive behaviour and mental health, enabling individuals to adjust their actions in anticipation of future events. Comprehensive documentation of this essential component of human cognitive development throughout different developmental periods is needed. Here, we investigated age-related changes in associative learning in key developmental stages, including infancy, childhood, adolescence, and adulthood. We employed a classical delay eyeblink conditioning paradigm that consisted of two sessions with a total of 48 paired trials. Our initial hypothesis was that performance in associative learning would increase linearly with age. However, our findings suggest that performance peaks during the primary school years: Children in this age-group exhibited superior performance compared to all other age-groups and displayed the most consistent and least variable learning. Adults and adolescents exhibited faster association learning than infants. An additional learning session supported learning in infants and adolescents indicating that during these developmental stages, consolidation processes are vital for learning. A comprehensive account of the development of associative learning may inform theories on aetiology and treatment options in clinical psychology and neurosciences. Learning associations via eyeblink conditioning was strongest in children ages 7 to 8 in comparison to infants, adolescents, and adults. A second learning session supported learning in infants and adolescents.

Associative learning can be observed from the neonatal period onwards, providing opportunities to examine changes in basic learning and memory abilities. One method that is suitable to study associative learning is classical eyeblink conditioning (EBC) which is dependent on the cerebellum. Extinction learning can be systematically investigated in this paradigm by varying the context during learning and extinction. Due to methodological difficulties and ethical challenges, no studies have compared extinction learning using EBC across human development. Our goal was to test feasibility of a 3-day delay EBC paradigm that can be used from infancy to adulthood. Acceptance/safety was tested especially for infancy by investigating attrition rates and parental report on infant wellbeing. On a paradigm side, we tested if the paradigm leads to successful acquisition and extinction. An air puff served as unconditional stimulus (US) and a tone as conditional stimulus (CS). On day 1 during acquisition, participants received 36 US-CS pairings in context A. On day 2, participants received 12 acquisition trials in context A to consolidate association learning, followed by 48 extinction trials (tone alone presentations) in context B. Renewal was assessed on day 3 and incorporated 12 CS alone trials presented in both the acquisition context and the extinction context. Eyeblink responses were videotaped and coded offline. The protocol was tested with 12- to 36-month-old infants (N=72), adolescents (N=8) and adults (N=8). Concerning the acceptance/safety side, attrition ranged from 21-58% in infant samples due to the complex preparation of the children for the paradigm. However, attrition is equal or lower compared to other infant learning paradigms. Parents of infant samples were very interested in the paradigm and reported low levels of infant stress, exhaustion and negative feelings during the sessions. Data quality was very high and no participant had to be excluded because of insufficient data. Concerning the paradigm side, participants showed successful acquisition and extinction as a group. The procedure is ethically sound, feasible, tolerated by many infants, and acceptable among parents. The data show successful acquisition and extinction rates, making the paradigm a valuable tool for investigating developmental changes in extinction learning over the lifespan.

A child's first words mark the emergence of a uniquely human ability. Theories of the developmental steps that pave the way for word production have proposed that either vocal or gestural precursors are key. These accounts were tested by assessing the developmental synchrony in the onset of babbling, pointing, and word production for 46 infants observed monthly between the ages of 9 and 18 months. Babbling and pointing did not develop in tight synchrony and babble onset alone predicted first words. Pointing and maternal education emerged as predictors of lexical knowledge only in relation to a measure taken at 18 months. This suggests a far more important role for early phonological development in the creation of the lexicon than previously thought.

Objectives While mindfulness-based parenting programs (MPPs) are increasingly popular for reducing child behavior problems, the evidence for the advantages of MPP over existing behavioral parent training is unclear. Existing systematic reviews have largely excluded the breadth of MPP protocols, including those that integrate behavioral skills components. Therefore, a scoping review was conducted to map the nature and extent of research on MPPs for parents of children aged 3 to 12 years with behavioral problems. Methods PRISMA-ScR guidelines were used to conduct an encompassing peer literature review of cross-disciplinary databases. Studies were included if they reported mindfulness interventions for parents of children aged between 3 and 12 years with externalizing behavior problems and had an outcome measure of child behavioral problems that could be represented as an effect size. Randomized controlled trials as well as quasi-experimental, pre-post studies and unpublished dissertations were included. Results Sixteen studies met the inclusion criteria ( N  = 1362). The majority of MPPs delivered mindfulness adapted to parenting based on the Bögels’ protocol within clinical settings. There was a dearth of fully integrated mindfulness and behavioral programs. MPPs generally produced pre-to-post-intervention improvements with small effect sizes across child behavior and parent style, stress, and mindfulness measures. Examining longer follow-up periods compared to pre-intervention, effects reached a moderate size across most outcome measures. Conclusions MPPs continue to show promise in improving child behavior and parental mindfulness, well-being, and style. Further research is needed to determine how to best leverage the advantages of mindfulness in augmenting the well-established effectiveness of behavioral programs.

Objectives Parents across a broad sociodemographic spectrum struggle with their children’s difficult behaviors and need effective and engaging interventions. We developed a mindfulness-enhanced behavioral parent training group program (MeBPT) aiming to be more inclusive and enable positive outcomes. This study investigated whether MeBPT can meet diverse needs across child, parent, family, and program-delivery factors, and explored whether improvements in parent-rated child behavior are predicted by changes in mindful parenting, parenting approach, or both. Method Participants were 338 parents of 3- to 12-year-old children presenting with externalizing problems to a university clinic in regional Australia. Factors that significantly correlated with improvements in parent and child outcomes or attendance were included in regression analyses. Results Improved parent-rated child behavior was predicted by change in mindful parenting ( p  = 0.019) but not parenting approach ( p  = 0.305). Attendance was high across all factors, and particularly for older parents. Improvements in parent well-being, approach, mindfulness, and child behavior were similarly large for families across child and family characteristics. Low-income families exhibited less improvement in parental well-being ( p  = 0.012), although demonstrated similar improvements in child behavior, parenting approach, and mindful parenting. Families with more severe problems at baseline showed largest gains ( p  < 0.002). Parental self-awareness and acceptance were important change agents. Conclusions MeBPT appears effective across various sociodemographic backgrounds and is particularly beneficial for families presenting with more severe behavioral problems. Controlled research with ethnically diverse families is needed to confirm the benefits of MeBPT and to allow examination of mediators and moderators.
