Parental Perceptions of Individual and Dyadic Adjustment as Predictors of Observed Coparenting Cohesion: A Cross-National Study.

Over the past 20 years, systemically guided approaches to understanding early family processes have helped to provide greater clarity concerning the interplay among individual, dyadic, and family level processes. Parental depression, marital functioning, and child adjustment in particular appear to be reliable predictors of coparental and family level functioning. Indeed, cohesion at the level of the family group covaries in theoretically meaningful ways with these indicators of individual and dyadic adjustment. In this study, two collaborating research groups (one in Switzerland, the second in the United States) partnered to examine whether similar patterns of relationships exist among individual and marital adjustment and coparenting processes in families of 4-year-old children. Using similar constructs but disparate and occasionally dissimilar measures, both groups measured parent-reported depression, marital satisfaction, and child behavior problems. Coparenting cooperation and warmth were observed during family interactions. Despite differences between samples and evaluation tools, similar results were found for the Swiss and U.S. samples. A model with depression, marital satisfaction, and child symptoms as predictors of a latent factor of observed coparenting cooperation and warmth showed good fit to data in both samples, suggesting the model was relevant for each. Parameter estimation showed that higher coparenting cooperation and warmth was predicted by lower maternal depression and higher child internalizing symptoms. The common significant effects despite differences in assessment paradigms and instrumentation are of substantive interest. Future directions pertinent to the coparenting questions addressed in this research are discussed.

Durante los últimos veinte años, los enfoques guiados sistemáticamente para comprender los procesos familiares iniciales han contribuido a aclarar mejor la interacción entre los procesos individuales, diádicos y familiares. La depresión de los padres, el funcionamiento conyugal y la adaptación de los niños en particular parecen ser predictores fiables del funcionamiento coparental y familiar. De hecho, la cohesión a nivel del grupo familiar covaría de formas teóricamente significativas con estos indicadores de adaptación individual y diádica. En este estudio, dos grupos de investigación colaboradores (uno en Suiza, el segundo en los Estados Unidos) se asociaron para analizar si existen patrones similares de relaciones entre la adaptación individual y la conyugal y los procesos de cocrianza en familias de niños de cuatro años. Utilizando constructos similares pero diferentes y medidas ocasionalmente disímiles, ambos grupos midieron la depresión, la satisfacción conyugal y los problemas de comportamiento de los niños informados por los padres. Se observó cooperación y cordialidad en la cocrianza durante las interacciones familiares. A pesar de las diferencias entre las muestras y las herramientas de evaluación, se hallaron resultados similiares para las muestras de Suiza y de los EE. UU. Un modelo con síntomas de depresión, satisfacción conyugal y síntomas en los niños como predictores de un factor latente de cooperación y cordialidad observado en la cocrianza demostró una bondad de ajuste a los datos en ambas muestras, lo cual sugiere que el modelo fue relevante para cada uno. Las estimaciones paramétricas demostraron que se predijo una mayor cooperación y cordialidad en la cococrianza por medio de una depresión materna más baja y una mayor internalización de los síntomas en los niños. Los efectos notables comunes, a pesar de las diferencias en los paradigmas de evaluación y la instrumentación, son de interés sustancial. Se debaten futuras indicaciones pertinentes a las cuestiones relativas a la cocrianza que se abordan en esta investigación.

Quality home visits: Activities to promote meaningful interactions.

Examination of and support for specific practices that promote high-quality home visiting are essential as family support programs continue to expand across the country. The current study used direct observation of 91 home visits across 41 home visitors to examine relations among interaction partners, content of the interactions, the home-visitors' activities, and quality of home-visitors' practices and family-members' engagement within programs funded by the Maternal, Infant, and Early Childhood Home Visiting program. More time spent in triadic interactions focused on child-related content, as measured by the Home Visit Rating Scale-Revised, was related to higher quality of family engagement in home visits, as measured with the Home Visit Observation Rating Scales. Time spent in adult-focused interactions and administrative tasks, however, was related to lower quality of home-visiting practices and family engagement. Implications for research and practice are discussed.

A medida que los programas de apoyo familiar continúan expandiéndose a lo largo del país, se hace esencial examinar y apoyar prácticas específicas que promueven la alta calidad de las visitas a casa. El presente estudio usó observaciones directas de 91 visitas a casa llevadas a cabo por 41 visitadores con el fin de examinar las relaciones entre la participación de todas las partes involucradas, el contenido de las interacciones, las actividades de los visitadores a casa, y la calidad tanto de las prácticas de los visitadores como de la participación de los miembros de la familia dentro de los programas subvencionados por MIECHV. Más tiempo empleado en interacciones tríadicas enfocadas en contenidos relacionados con el niño, tal como se midió por medio de las Escalas Revisadas de Evaluación de Visitas a Casa (HVOF-R; McBride y Peterson, 1996), estuvo relacionado con más alta calidad de la participación de la familia en las visitas a casa, tal como se midió por medio de las Escalas de Evaluación de la Observación de Visitas a Casa (HOVRS; Roggman et al., 2014). El tiempo empleado en interacciones enfocadas en los adultos y tareas administrativas, sin embargo, estuvo relacionado con más baja calidad de las prácticas de visita a casa y participación de la familia. Se discuten las implicaciones para la investigación y la práctica.

L'examen et le soutien de pratiques spécifiques qui promeuvent la visite à domicile de qualité sont essentiels alors que les programmes de soutien à famille continuent de se développer aux Etats-Unis. Cette étude a utilisé une observation directe de 91 visites à domicile effectuées par 41 visiteurs afin d'examiner les relations entre les partenaires d'interaction, le contenu des interactions, les activités des visiteurs ou visiteuses à domicile, et la qualité des pratiques des visiteurs ou visiteuses à domicile ainsi que l'engagement des membres de la famille au sein des programmes américains de visite à domicile subventionnés par le programme américain Maternal, Infant, and Early Childhood Home Visiting. Plus de temps passé dans les interactions triadiques mettant l'accent sur le contenu lié à l'enfant tel qu'il est mesuré par la version révisée de l'Echelle d'Evaluation de la Visite à Domicile (HVOF-R; McBride & Peterson, 1996) a été lié à une plus grande qualité de l'engagement de la famille durant les visites à domicile telles qu'elles ont été mesurées au moyen des Echelles d'Evaluation de l'Observation de la Visite à Domicile (HOVRS; Roggman et al., 2014). Le temps passé en interactions avec les adultes et en tâches administratives étaient lié à des pratiques de visite à domicile et à un engagement familial de moindre qualité. Les implications pour les recherches et la pratique sont discutées.

Folding with a protein's native shortcut network.

A complex network approach to protein folding is proposed, wherein a protein's contact map is reconceptualized as a network of shortcut edges, and folding is steered by a structural characteristic of this network. Shortcut networks are generated by a known message passing algorithm operating on protein residue networks. It is found that the shortcut networks of native structures (SCN0s) are relevant graph objects with which to study protein folding at a formal level. The logarithm form of their contact order (SCN0_lnCO) correlates significantly with folding rate of two-state and nontwo-state proteins. The clustering coefficient of SCN0s (CSCN0 ) correlates significantly with folding rate, transition-state placement and stability of two-state folders. Reasonable folding pathways for several model proteins are produced when CSCN0 is used to combine protein segments incrementally to form the native structure. The folding bias captured by CSCN0 is detectable in non-native structures, as evidenced by Molecular Dynamics simulation generated configurations for the fast folding Villin-headpiece peptide. These results support the use of shortcut networks to investigate the role protein geometry plays in the folding of both small and large globular proteins, and have implications for the design of multibody interaction schemes in folding models. One facet of this geometry is the set of native shortcut triangles, whose attributes are found to be well-suited to identify dehydrated intraprotein areas in tight turns, or at the interface of different secondary structure elements.

Triadic Interactions in MIECHV: Relations to Home Visit Quality.

Objectives This study was conducted to look inside home visits to examine active intervention ingredients used and their relations with ratings of home visit quality. In particular, triadic interactions that engage the home visitor, parent, and child together and provide a context for home visitors to facilitate parent-child interactions by observing, modeling and coaching behaviors that promote optimal child development were examined. Methods Observations were conducted to describe intervention activities (with the HVOF-R) and rate quality of home visit practices and engagement (with the HOVRS A+). Results Analyses revealed the majority of home visit time (71%) was spent in home visitor-parent interactions with only a small proportion of home visit time (17%) spent in triadic interactions and an even smaller proportion of time (2%) during which home visitors actively coached parent-child interactions. Amount of time spent in triadic interactions was related positively to quality ratings of home visit practices and engagement. Moreover, time spent coaching parent-child interactions uniquely predicted home visit quality after accounting for visit length and home visitor time spent observing and modeling. Conclusions for Practice Increasing the percentage of home visitors engage the parent and child in triadic interaction should be a focus for home visiting programs. Home visitors will likely need professional development and supervisory support to enhance their skills in coaching parent-child interactions during triadic interactions.

Are family relations connected to the quality of the outcome in adolescent anorexia nervosa? An observational study with the Lausanne Trilogue Play.

The study aims to explore the connection between the family interactive patterns, investigated with a standardized observational tool based on a recorded play session, the Lausanne Trilogue Play, and the outcome of adolescent patients with anorexia nervosa after a 6 months treatment, based on the Morgan-Russel Outcome Assessment Schedule. Seventy-two parents and adolescent daughters with anorexia nervosa, consecutively referred to an adolescent neuropsychiatric service, participated in the study and underwent an integrated model of treatment, based on constant neuropsychiatric and dietary monitoring, weekly individual psychotherapy for the daughter, and parental counselling and support. A better adolescents' functioning in family relationships, in particular in the triadic ones, at first assessment, was associated with a better outcome. Data on family interactions may help predict the most appropriate intervention for the patient and his family.

A Longitudinal Study of Parental Depressive Symptoms and Coparenting in the First 18 Months.

Although the negative impact of postpartum depression on parenting behaviors has been well established-albeit separately-for mothers and fathers, the respective and joint impact of both parents' mood on family-group interactive behaviors, such as coparenting support and conflict behaviors between the parents, have not yet been investigated. The aim of this study was to examine the association between parental depressive symptoms and coparenting behaviors in a low-risk sample of families with infants, exploring reciprocity between the variables, as well as gender differences between mothers and fathers regarding these links. At 3 (T1), 9 (T2), and 18 months postpartum (T3), we assessed both parents' depressive symptoms with a self-report questionnaire and observed coparenting support and conflict during triadic mother-father-child interactions. The results revealed that higher maternal depressive symptoms at T1 were associated with lower support at T1 and T2. Conflict at T3 was associated with higher maternal depressive symptoms at T3 and, more surprisingly, with less depressive symptoms in mothers at T2 and fathers at T3. Cross-lagged associations suggested that parental depressive symptoms were more likely to influence coparenting than the reverse. Moreover, maternal depressive symptoms were more likely to be linked to coparenting behaviors than were paternal depressive symptoms. These results confirm that parental-mostly maternal-depressive symptoms, even of mild intensity, may jeopardize the development of healthy family-level relations, which previous research has shown to be crucial for child development.

BEYOND THE DYAD: THE RELATIONSHIP BETWEEN PRESCHOOLERS' ATTACHMENT REPRESENTATIONS AND FAMILY TRIADIC INTERACTIONS.

This study examines the relationship between triadic family interactions and preschoolers' attachment representations, or internal working models (IWMs), from a qualitative and dimensional perspective. Individual, relational, and sociocultural variables were evaluated using two different samples. The results showed that triadic family interactions were linked to preschoolers' attachment security levels in both groups, indicating the reliability of the proposed model.

Imagining triadic interactions simultaneously activates mirror and mentalizing systems.

Coordinated triadic interactions, involving oneself, another person, and an external object, are considered a uniquely human skill. However, the exact mechanisms underlying the ability to engage in such social interactions remain hitherto unknown. We used functional neuroimaging to investigate the neural signature of triadic interactions. For this purpose, participants viewed pictures of objects in a 3T functional magnetic resonance imaging scanner and were asked whether they could imagine this object in a social interaction with another person. We also aimed to dissociate this process from, as well as to find commonalities with, purely self-referential or other-referential processing. In all trial-types, we found activations in core mentalizing brain areas (medial prefrontal cortex, posterior cingulate cortex, precuneus and temporoparietal junction). Furthermore, triadic engagements, but not self-referential or other-referential processing, were associated with activations in classical mirror neuron areas (inferior frontal gyrus and inferior parietal lobe). Finally, mentalizing networks showed a strong functional connectivity with mirror neuron areas exclusively during triadic engagements. These results suggest that the imagined interaction of two agents is processed in a more complex neural social cognitive network than purely self- or other-referential considerations.

Triadic Collaboration Between Adolescents, Caregivers, and Health-Care Providers to Promote Healthy Behavior.

PURPOSE: To further elucidate the various aspects of the triadic relationship between health-care providers (HCP), adolescents, and caregivers during adolescent health-care visits, with the goal of helping HCPs better understand how they can best support adolescents to choose healthy behaviors. METHODS: Adolescents (ages 13-18 years) and caregivers of adolescents were recruited to participate in qualitative interviews regarding preferences for provider interactions around health behavior change. Data analysis was conducted using inductive thematic analysis to identify and describe patterns of themes across the dataset. RESULTS: Thirty one adolescents and 30 caregivers participated. Fourteen themes emerged in the analysis regarding adolescent and caregiver preferences for direct and indirect relationships between adolescents, caregivers, and HCPs in promoting healthy behavior. These themes were organized into a triadic collaboration framework to promote healthy behavior using an adolescent-centered and caregiver-involved approach. DISCUSSION: This study supports findings of previous research on triadic interactions between HCPs, adolescents, and caregivers while deepening our understanding of the HCP's role in helping adolescents to choose healthy behaviors. These themes are representative of the continuing shift toward an adolescent-centered and caregiver-involved approach to adolescent health care and provide further guidance to HCPs on how to work collaboratively with both adolescents and caregivers to promote healthy behaviors and improve health outcomes.

TIAP: an observational procedure for assessing family relationships: a clinical case from the parenting evaluation context.

TIAP is an observational procedure to assess family functioning detecting simultaneously the role of each participant and the interdependence of relational behaviors. In particular, the procedure requires family members to play according to different interactive configurations (parent1-children; parent2-children, all together, children and parents as separate units) and therefore different microtransitions from one configuration to another. As such, the procedure allows to study how family members coordinate to maintain stability, promote change, and encourage members to explore different interactive configurations within the family system. TIAP has been validated through several studies conducted with different non-clinical groups of families that have highlighted the salient aspects of family functioning, and significant correlations with variables external to the family system, such as children's social-emotional competence in the educational context. This paper focuses on the use of TIAP in the contexts of assessing parental competence. Specifically, the article aims to describe, through the reference to a clinical case, the results emerged from a study conducted with 33 families involved in a parenting assessment process. The study is part of a broader collaborative project between the Child and Adolescent Neuropsychiatry Clinic of the Italian National Health Service in Parma, the University of Parma, and the Bologna Family Therapy Center. TIAP was administered to all the families involved as a complement to other tools routinely used for all cases handled by the professionals of the clinic. The coding system includes different indices. Some analyze the interactive family modes: family coordination (mutual attention and responsiveness), the responses to potentials for change (disregard, absorption, amplification), and intra-familiar exploration. Other indices concern the quality of the interactions: the relational triadic dynamic of microtransition (detaching-entrusting-welcoming-joining) and the consistency/inconsistency of the communication channels. The results highlighted how TIAP makes it possible to identify the specific interactive modalities of the different members and their interdependence and reciprocity, favoring the identification of both family weaknesses and family resources, including the children's contribution. Furthermore, the general data trend showed that TIAP indices detect some important prognostic elements capable of guiding the court's decisions.

Early triadic interactions in the first year of life: a systematic review on object-mediated shared encounters.

Infants' early interactions with adults and everyday objects are key to socio-communicative development, but their emergence and development are still under debate. Aiming at describing the diversity of theoretical and methodological approaches on triadicity during the first year of life, we conducted a systematic and qualitative review of recent literature. Following PRISMA 2020 guidelines, we explored the scientific production of recent decades on triadic interactions up to 12 months of age. We initially screened 1943 items from which we obtained a final sample of 51 publications. Studies are usually conducted in laboratory settings, while ecological research is becoming increasingly common, especially in home settings. According to a thematic analysis of the data, we discussed the different perspectives on the origin and conceptualization of triadic interactions, and how they contribute to structuring and facilitating other developmental phenomena, such as the children's communicative gestures and uses of objects. Prior to the origin of intentional communication, adults facilitate early forms of triadicity based on fostering opportunities for infants' communication and engagement with both adults and materiality. However, there is a need for further research that explore the potential of early triadic interactions for parenting and early childhood education practises.

Family alliance as a developmental antecedent of depressive and anxiety symptoms in early adolescence: Friendship quality as a mediating factor.

Family interactions constitute a critical context in which children can learn the basic relational skills that they need to make friends. In turn, friendship quality is a robust predictor of child socioemotional functioning. Therefore, friendship is likely to act as a bridge in a socioemotional developmental cascade linking early family interactions to child subsequent socioemotional adjustment. This study aimed to examine a mediation model linking family alliance (the degree of mother-father-child engagement and coordination in joint activities) in kindergarten to anxiety and depressive symptoms in early adolescence through the mediating role of friendship quality in middle childhood. The family alliance of 87 mother-father-child triads was assessed when children were aged 6 years based on a 15-min videotaped interaction. Children reported on the quality of their relationship with their best friend at age 10 and on their anxiety and depressive symptoms at both 12 and 13 years (averaged). Results showed that children who experienced better family alliance at 6 years had higher relationship quality with their best friend at 10 years which in turn, predicted less anxiety (but not depressive) symptoms in early adolescence. There was a significant indirect effect of family alliance on anxiety through friendship quality. Findings suggest that family alliance may play a central role in shaping children's capacity to develop high-quality friendships, with implications for their subsequent socioemotional functioning. Further longitudinal studies are needed to examine the reciprocal influences unfolding over time that are likely to characterize developmental cascades among family systems, children's developing friendships, and their socioemotional functioning.

The multimodality of infant's rhythmic movements as a modulator of the interaction with their caregivers.

Children's rhythmic movements during the first year of life possess a meaningful predictive validity for later communicative development. However, their role within adult-child interactions is still underexplored. In this study, we examined whether children's rhythmic movements were significantly responded by adults and the role of multimodality and object use in this process. We observed 22 dyads of 9-month-olds and their parents in natural play interactions. Infants' multimodal rhythmic movements increased the probability of adult responding. Adults offered different types of responses and significantly followed the child's focus of attention. These dynamics could support communicative development by promoting joint attention frameworks.

What's an early triadic interaction made of? A methodological proposal to study the musical dynamics of interaction.

Classical theories of intersubjectivity hold that the first interactions in which children participate are dyadic (adult-baby). However, thanks to the material shift that is taking place in the cognitive sciences, an increasing number of authors began to recognise the constitutive role that materiality has for cognition, from the very beginning of life. Interactions do not occur in a vacuum, but within a meaning-loaded material world that adults actively seek to bring to children. While in the field of dyadic interactions studies on communicative musicality have shown how interactive exchanges are structured and how that structure unfolds over time, little is known yet about the internal structure of early triadic interactions. In this paper, we propose a longitudinal, mixed and multilevel methodological framework aimed at describing the dynamics of the musical organisation of early triadic interactions between adults, babies and things, and its development over different timescales. We conclude that if researchers want to fully understand early triadic interactions and their musical structuring, further studies that take into account the cognitive relevance of things and the dynamics of our interactions with and through materiality are needed.

Focus on family functioning in anorexia nervosa: new perspectives using the Lausanne Trilogue Play.

31 families of female adolescents affected by anorexia nervosa (AN) and 20 of girls with emotional and behavioral disorders participated in a semi-standardized videotaped game: the Lausanne Trilogue Play (LTPc). We aimed to clarify if there is a typical AN family profile and if the LTPc procedure could predict the risk of developing AN. We confirmed that AN families exhibit dysfunctional alliances. Particularly because of the difficulty of the three members to be available to the interaction at least with their body (participation) and to comply with the role expected at each stage of the game (organization). Moreover, these families show a significant worse functioning, especially regards to the mother-daughter phase of the game, in focal attention and affective contact functional levels, while in triadic and couple phases they present lower scores than comparison group in all functional levels. Furthermore, we found that LTPc may predict the possibility of belonging to a family with a daughter with AN rather than one whose daughter has a different disorder. Therefore, LTPc would allow clinicians foresee the risk of developing AN and tailoring the most suitable therapeutic intervention and finally see its effectiveness using LTPc for later follow-up video feedback sessions.

Communicative Mediation by Adults in the Construction of Symbolic Uses by Infants.

Adult semiotic mediation in the origin and evolution of the first symbolic uses of objects by infants in contexts of triadic interactions was investigated. Six infant-parent dyads interacting together with ten objects were observed longitudinally from 9 to 15 months of age, with an interval of three months between each observation. The communicative mediators used by adults, in the form of demonstrations and ostensive gestures, decrease as infants grow up. The orchestration of these semiotic mediators also decreases and the functions of the demonstrations change. At the beginning, the adults use them merely to demonstrate the symbolic uses of object, but later they use them to evaluate, complete or correct the symbolic uses by the infants. The semiotic mediators are first used to guide the child at the level of attention and later at the level of cultural practices of symbolic uses of objects. These changes in communicative mediators and their functions reveal the educational role of adults through adjustment in communication, always in tune with the infant's knowledge and performance.

The Diaper Change Play: Validation of a New Observational Assessment Tool for Early Triadic Family Interactions in the First Month Postpartum.

The quality of family relations, observed during mother-father-infant triadic interactions, has been shown to be an important contributor to child social and affective development, beyond the quality of dyadic mother-child, father-child, and marital relationships. Triadic interactions have been well described in families with 3 month olds and older children using the Lausanne Trilogue Play (LTP). Little is known about the development of mother-father-baby interactions in the very 1st weeks postpartum, mostly because no specific observational setting or particular instrument had been designed to cover this age yet. To fill this gap, we adapted the LTP to create a new observational setting, namely the Diaper Change Play (DCP). Interactions are assessed using the Family Alliance Assessment Scales for DCP (FAAS-DCP). We present the validation of the DCP and its coding system, the FAAS-DCP. The three validation studies presented here (44 mother-father-child-triads) involve a sample of parents with 3-week-old infants recruited in two maternity wards (n = 32 and n = 12) in Switzerland. Infants from both sites were all healthy according to their APGAR scores, weight at birth, and scores on the NICU Network Neurobehavioral Scale (NNNS), which was additionally conducted on the twelve infants recruited in one of the maternity ward. Results showed that the "FAAS - DCP" coding system has good psychometric properties, with a good internal consistency and a satisfying reliability among the three independent raters. Finally, the "FAAS-DCP" scores on the interactive dimensions are comparable to the similar dimensions in the FAAS-LTP. The results showed that there is no statistically significant difference on scores between the "FAAS-DCP" and the "FAAS," which is consistent with previous studies underlying stability in triadic interaction patterns from pregnancy to 18 months. These first results indicated that the DCP is a promising observational setting, able to assess the development of the early family triadic functioning. The DCP and the FAAS-DCP offer to both clinicians and researchers a way to improve the understanding of the establishment of early family functioning as well as to study the young infant's triangular capacity. Perspectives for future research will be discussed.

Bridging the Gap across the Transition to Coparenthood: Triadic Interactions and Coparenting Representations from Pregnancy through 12 Months Postpartum.

Most family researchers agree that the coparenting relationship emerges some time during the transition to parenthood, though it is unclear whether it originates in pregnancy. Previous studies demonstrated that couples' positive representations of their future coparenting relationship and harmonious coparenting behaviors observed during prenatal triadic interactions predicted better postpartum functioning. However, previous studies did not simultaneously assess prenatal coparenting behaviors and representations as predictors of postpartum coparenting. If the coparenting relationship originates during pregnancy, these behavioral and cognitive aspects of prenatal coparenting should show associations with their postpartum counterparts. Based on family systems-, attachment-, and social-learning theory, the first aim in this study was to explore whether prenatal coparenting representations and behaviors are associated with postpartum coparenting, which would suggest that both cognitive and behavioral aspects of the coparenting relationship emerge during pregnancy. A second aim was to determine whether parental coparenting representations are consistent with concurrently observed coparenting behaviors. A sample of 55 couples expecting their first child was observed during triadic interactions during pregnancy and at 3- and 12-months postpartum. Observations were coded using the Coparenting and Family Rating System. Composite scores were formed to reflect harmonious and antagonistic coparenting behaviors. Parents' representations of harmonious and antagonistic coparenting were assessed via interviews and questionnaires during pregnancy and at 3- and 12-months postpartum. Results indicated that prenatal representations of harmonious and antagonistic coparenting were associated with and predicted unique variance in respective postpartum coparenting representations. Prenatal coparenting behaviors were also associated with coparenting behaviors observed during 3-months-play and 12-months-mealtime interactions and predicted unique variance in postpartum coparenting. Surprisingly, prenatal coparenting representations were not associated with prenatal behaviors, though representations and behaviors were associated at 3 months postpartum. Findings suggest that the coparenting relationship originates during pregnancy with prenatal coparenting representations and behaviors bridging the gap across the transition to coparenthood. Future studies should include assessments of both cognitive and behavioral facets of the prenatal coparenting relationship.

Developmental Changes in Locating Voice and Sound in Space.

We know little about how infants locate voice and sound in a complex multi-modal space. Using a naturalistic laboratory experiment the present study tested 35 infants at 3 ages: 4 months (15 infants), 5 months (12 infants), and 7 months (8 infants). While they were engaged frontally with one experimenter, infants were presented with (a) a second experimenter's voice and (b) castanet sounds from three different locations (left, right, and behind). There were clear increases with age in the successful localization of sounds from all directions, and a decrease in the number of repetitions required for success. Nonetheless even at 4 months two-thirds of the infants attempted to search for the voice or sound. At all ages localizing sounds from behind was more difficult and was clearly present only at 7 months. Perseverative errors (looking at the last location) were present at all ages and appeared to be task specific (only present in the 7 month-olds for the behind location). Spontaneous attention shifts by the infants between the two experimenters, evident at 7 months, suggest early evidence for infant initiation of triadic attentional engagements. There was no advantage found for voice over castanet sounds in this study. Auditory localization is a complex and contextual process emerging gradually in the first half of the first year.

Rhythmic ostensive gestures: How adults facilitate infants' entrance into early triadic interactions.

For decades, the literature on the emergence of triadic interactions considers the end of the first year of life as the time when children become able to communicate with others intentionally about a referent. Prior to that, children only relate in dyads, either with someone else or with an object. However, several researchers claim that referents are not naturally given in human communication and that they need to be established in interaction with others. In this study, we focus on earlier triadic interactions initiated by adults, when young babies still require an adult to bring the material world within their reach. In these early triadic interactions, ostensive gestures (with the object in the hand) are one of the first means of enabling the establishment of shared reference. Such gestures are easier to understand since sign (gesture) and referent (object) coincide. We conducted a longitudinal study with 6 babies filmed at 2, 3 and 4 months old in interaction with their mothers and a sounding object (a maraca). We analyzed different communicative initiatives by the adult and the child's responses. The results show that children come to understand the adult's communicative intention gradually through interaction. Adults include children in organized communicative "niches" based on ostensive actions, both through ostensive gestures and demonstrations of the use of the object. Consequently, the first shared understandings between adult and child take place around the object and its uses. Rhythm is a powerful tool used to structure the interaction. Eventually, adults provide space to children to actively interact with the sounding object themselves. These results highlight the importance of considering ostensive actions as a communicative tool that favors joint attention and action. They also bring some light to the interdependence between a child who actively perceives and acts, and the structured situation that the adult organizes for them.
