Neurodevelopmental disability (ND) poses a significant challenge to infants' socio-emotional and cognitive development, as well as to caregiving dynamics, such as parental sensitivity and mother-infant interaction. Prior research highlights the crucial role of early parenting support interventions in enhancing parental behaviors, serving as a protective developmental factor for children at risk for or diagnosed with ND. This single-cohort, multicentric study aims to evaluate the efficacy of early video-feedback intervention (VFI) in improving maternal parenting behaviors. Thirty-four mothers with their children diagnosed with ND participated in the study. Different dimensions of parenting behavior (i.e., affection, responsiveness, encouragement, teaching) were assessed during 10-minute mother-infant interactions, both before (T0) and after (T1) completing six weekly VFI sessions. Additionally, mothers completed standardized questionnaires assessing parenting stress, anxiety, and depressive symptoms. The results indicated significant improvements in maternal responsiveness, encouragement, and teaching following the intervention. Furthermore, mothers reported a state anxiety reduction at T1. Additionally, higher scores in affection and responsiveness were correlated with reduced maternal stress. These findings support the utility of VFI as a valuable tool for enhancing positive parenting skills in the context of ND, and provide insights into the dyadic processes through which parenting behaviors may promote socio-emotional and cognitive development in children with ND.

Gestational Age (GA) at birth plays a crucial role in identifying potential vulnerabilities to long-term difficulties in cognitive and behavioral development. The present study aims to explore the influence of gestational age on the efficiency of early visual attention orienting, as a potential marker for the development of specific high-level socio-cognitive skills. We administered the Gap-Overlap task to measure the attentional orienting and disengagement performance of 16-month-olds born between the 34th and 41st weeks of gestation. Our findings indicate that GA might be a significant predictor of attentional disengagement performance, with lower GAs associated with slower orienting of visual attention in the gap condition. Additionally, we discuss a possible influence of endogenous attention control on disengagement accuracy at this age, particularly among full-term infants. Overall, the findings highlight the role of GA as a key factor in evaluating early visual attention development, acting as a marker for detecting early vulnerabilities.
出生时的妊娠年龄（GA）在识别认知和行为发展长期困难的潜在脆弱性方面起着至关重要的作用。本研究旨在探讨胎龄对早期视觉注意定向效率的影响，以此作为特定高级社会认知技能发展的潜在标志。我们采用 "间隙-重叠 "任务来测量妊娠34周至41周期间出生的16个月大儿童的注意定向和脱离表现。我们的研究结果表明，GA 可能是注意力脱离表现的重要预测因素，较低的 GA 与间隙条件下较慢的视觉注意力定向有关。此外，我们还讨论了内源性注意控制对这个年龄段的脱离准确性可能产生的影响，尤其是在足月儿中。总之，研究结果强调了性别差异作为评估早期视觉注意力发展的关键因素的作用，它是检测早期脆弱性的标志。

Benefits of attachment security have been demonstrated in multiple realms of development, and an extensive body of research has identified some of the antecedents associated with the development of secure attachments. While previous research has indicated that infant massage may support the development of mothers’ attachment to their babies, no published research exists that investigated infants’ attachment security after mothers learn infant massage strokes. This study tested the impact of an infant massage intervention on mothers’ massage frequency and attachment security in infants. Fifty-eight mother-infant dyads were randomly assigned to a treatment (massage, n = 28) or control (education, n = 30) group. Most mothers had preschool aged children participating in Head Start as well as an infant under 8 months of age; the remaining mothers were from the community. Mothers in the treatment group completed 4 weeks of infant massage training using standard strokes from Infant Massage USA, a chapter of the International Association of Infant Massage, headquartered in Sweden. At 12 months, mothers were guided through the standard sorting procedure of the Attachment Q-set (Waters, 1987). The treatment was effective, as 86 % of mothers in the massage group were still massaging their babies at the follow-up, an average of 10 months later, and infants whose mothers massaged them had higher attachment security scores. Surprisingly, 29 % of the mothers in the comparison group reported that they massaged their babies. A treatment X massage frequency ANOVA indicated that 12-month-old infants whose mothers in the treatment group had massaged them more than once per week were more securely attached than infants of mothers who massaged their infants less than once per week and also were more securely attached than infants in the comparison group. However mothers in the control group defined massage, it was not associated with infant attachment security at the follow-up. These results indicate that this inexpensive, easy to implement intervention effectively increased mothers’ ongoing use of infant massage, which in turn predicted more attachment security in their infants.

Background
Preterm children are a risk group for neurodevelopmental delays, while interactions with their mothers may serve as a protective factor.
Aims
The objectives of this study were to (1) identify changes in preterm children's neurodevelopment, maternal skills, and mother-child interactions of preterm children from the first to the second year of life; (2) analyze differences between preterm children with and without developmental delays in relation to social skills, parenting skills, and mother-child interaction; and (3) examine the risk and protective factors associated with the neurodevelopment of preterm children.
Methods
Participants included 47 Brazilian preterm children and their mothers, assessed at the first (Mage/months = 10.4, SD =3.6) and second (Mage/months= 26.2, SD=8.5) years of life, using corrected age. The Bayley Scale of Infants and Toddler Development -III and the Interaction Rating Scale were used for assessment.
Results
Cognitive and language scores decreased from the first to the second year of life, while children's motor and social skills, parenting skills, and mother-child interactions remained stable. In the second year of life, neurodevelopmental delays were associated with lower social skills, reduced parenting skills, and less evident mother-child interactions. Significant factors influencing child neurodevelopment in the first year of life included the number of children at home, NICU stays, maternal age, and parenting practices that foster cognitive growth. In the second year, neurodevelopment was primarily influenced by mother-child interactions and breastfeeding. Additionally, the number of children at home, child autonomy, responsiveness to the mother, breastfeeding, and family income were predictors of neurodevelopment in the second year.
Conclusion
The results underscore the importance of enhancing mother-child interactions and parenting skills to promote neurodevelopment in premature children. The findings provide valuable insights for intervention programs targeting social skills, aimed at fostering positive peer interactions and facilitating social integration among children with developmental challenges.

The way in which a mother and her preterm baby interact, especially in moments preceding or following stressful events, is fundamental in shaping the infant's autoregulation. Patterns of mutual sequential coordination constitute stress regulation competences and provide foundation for later socio-emotional development. Maternal affective touch has been postulated as an essential regulatory factor in early social exchange. In this study we aimed to better understand the interplay between maternal affective tactile behaviors and physiological synchrony between mother and child, with possible implications for early bonding processes. Fifteen mother-premature infant dyads were video-recorded during a free interaction and directly after a skin-interrupting medical procedure (vaccination or blood sampling) in the Neonatal Intensive Care Unit. The proportion of maternal affective touch was coded both in free and post-stress interactions. Parasympathetic response was assessed simultaneously in mothers and neonates in order to observe physiological synchrony in dyads. Finally, interactional misattunement during mothers' comforting actions and infant behavior after stress was evaluated as a potential indicator of risk in early bonding processes. Results indicated a positive association between the duration of maternal affective touch and adaptive autonomic synchrony patterns in dyads. Correlations were found between maternal affective touch both before and after stress-inducing procedure and several synchrony measures from free interaction phase (Spearman ρ = –0,57 do 0,72, p < 0,05) Additionally, the study revealed a positive correlation between the level of interactional misattunement and the duration of maternal affective touch after stress (ρ = 0,47, p < 0,05). The quality of synchrony was better in free interactions than during post-stress kangaroo care phase (p < 0,05).

The developmental trajectories of tone perception among tone and non-tone language learning infants have received wide attention and discussion in recent decades under the perceptual attunement framework. Nevertheless, tone perception in infants from pitch accent and bilingual language backgrounds has not been well understood. The present study examined monolingual and bilingual Norwegian-learning infants’ discrimination of two Cantonese tone contrasts at 5 and 10 months, ages corresponding to the onset and offset of perceptual attunement. Results showed that while monolingual infants were sensitive to the salient contrast, bilingual infants showed sensitivity to both contrasts at 10 months. In sum, infant age and bilingual language background affected discrimination. Pitch accent language experience or contrast salience may also play a role. The finding that early bilingual experience facilitated tone perception is of particular interest. It suggests that infant perception could be enhanced by a more complex linguistic environment on a broader level. As this was observed only at 10 months, cumulative exposure may be required for infants in a complex bilingual environment. Future studies should disambiguate explanations generated from the current finding, ranging from neurocognitive plasticity to perceptual salience, and from experience-dependent to independent possibilities.

In previous research, infants’ performance on speech perception tasks has been shown to predict later language outcomes, typically vocabulary size. We used Bayesian analyses to model trial-level looking time behavior of individual infants on morphological segmentation experiments. We compared the usefulness of Bayesian estimates and the raw looking time difference measures used in previous studies to predict (a) vocabulary size at 30 months and (b) outcome measures obtained from language samples elicited via a picture description task at 36 months. We found that both estimates of morphological segmentation reliably predicted expressive vocabulary at 30 months. The Bayesian estimate also credibly predicted the correct use of verb tense morphemes obtained from the language sample. We therefore conclude that the Bayesian estimate is better for indexing individual differences in segmentation tasks and more useful for predicting clinically relevant language outcomes.

Recent research has shown that children as young as 19 months demonstrate graded sensitivity to mispronunciations in consonant onsets and vowels in word recognition tasks. This is evident in their progressively diminishing attention to relevant objects (e.g., a dog) as mispronunciations increasingly deviate from the correct word form (such as /dog/ changing to /gog/, /kog/, or /sog/). Despite these sensitivities, uncertainties remain about their broad generalizability, especially regarding the differences between word onsets and codas, and between lexical segmental (consonants and vowels) and supra-segmental (e.g., lexical stress and tones) elements. The present study aimed to fill these gaps. Using the intermodal preferential paradigm, we conducted two experiments to evaluate toddlers’ responses to coda and lexical tone mispronunciations. Our results revealed a linear decline in toddlers' attention to familiar objects as mispronunciations became more severe, suggesting that by 19–20 months, infants' lexical representations encompass detailed phonetic information of both segmental and supra-segmental categories. Moreover, our results indicate that toddlers utilize these details in lexical processing. Such findings offer a more comprehensive understanding of the phonetic structures within toddlers' early lexical representations, sheding light on the mechanisms toddlers use in processing various word positions, across different acoustic dimensions, and in multiple languages.

The purpose of this research was to examine the role of a range of play and learning activities in the home (e.g., painting, playing games, reading, singing and letters and numbers) in the socioemotional development of young children. While many previous studies have focused on the benefits of home learning activities for language and literacy outcomes, less research has examined the role of these individual activities in other aspects of development, such as prosocial behaviour. Using a bioecological framework, a secondary analysis of data from the nationally representative Growing Up in Ireland(GUI) Study was conducted. The sample consisted of 9793 children, aged 36 months (50.7 % male and 49.3 % female). The study examined if the frequency of engagement in different play activities predicted scores on measures of internalising, externalising and prosocial behaviours using the Strengths and Difficulties Questionnaire. Findings indicated that informal play activities such as games, painting and drawing, and reading predicted socioemotional development scores, in comparison with activities such as letter or number games, even after parental and other family factors are accounted for. The results also indicated that parent-child relationship factors of warmth, hostility and closeness are particularly important for socioemotional development. Findings are discussed in the context of Bronfenbrenner’s bioecological model of development.

Forty years ago, Werker and Tees (1984) published a seminal finding which launched a proliferation of new research on early language learning. Their startling discovery, that infants demonstrate high initial sensitivity to phonetic contrasts which then attenuates over the first year of life, has provided deep insights into the origins of language learning. It has since stimulated a significant body of research investigating this early developmental process. This vast body of empirical work led to a theory of perceptual narrowing, which prevails today as a domain-general mechanism of environmental adaptation. In this article, I offer future directions for empirical and theoretical growth of perceptual narrowing theory with particular attention to issues of diversity, representation and generalizability. In addition, I discuss the importance of integrating empirical variation into perceptual narrowing theory.
