The roles of maternal mind-mindedness and infant security of attachment in predicting preschoolers’ understanding of visual perspective taking and false belief

Early relational origins of Theory of Mind: A two-study replication

BACKGROUND

Research implies early relational factors - parental appropriate mind-mindedness (MM) and mutually responsive orientation (MRO) - as antecedents of children's Theory of Mind (ToM), yet the longitudinal path is unclear. Furthermore, little is known about the process in father-child relationships. In two studies of community families in a Midwestern state in United States, we tested a path from parental appropriate MM in infancy to parent-child MRO in toddlerhood to children's ToM at preschool age in mother- and father-child relationships, using comparable observational measures at parallel ages.

METHODS

In Children and Parents Study (CAPS) of children born in 2017 and 2018, we collected data at 8 months (N = 200, 96 girls), 38 months, age 3 (N = 175, 86 girls), and 52 months, age 4.5 (N = 177, 86 girls). In Family Study (FS) of children born mostly in 2001, we collected data at 7 months (N = 102, 51 girls), 38 months, age 3 (N = 100, 50 girls), and 52 months, age 4.5 (N = 99, 49 girls). Parental MM (verbal comments aligned with the infant's psychological state) was observed in infancy, MRO (parent and child responsiveness to each other and shared positive affect) at age 3, and ToM (false belief tasks) at age 4.5.

RESULTS

The findings supported the proposed indirect effects of parents' MM on children's ToM, mediated by MRO, for fathers and children in both studies, and for mothers and children, in CAPS. In FS, mothers' MM predicted MRO and ToM, but there was no mediation.

CONCLUSIONS

This investigation, testing a path from MM to MRO to ToM in both mother- and father-child relationships in two longitudinal studies, adds to the literature that has described relations among those constructs but rarely integrated those in one model.

Mothers' Mental State Talk and 3- to 5-Year-Old Children's Theory of Mind: Their Reciprocal Dynamic Impact

The development of children's social function is influenced by the social environment, and children also play an active role in shaping and nurturing this environment. The present study investigated the potential reciprocal dynamic impact of mothers' mental state talk (MST) and the development of theory of mind (ToM) in children. Using a cross-sectional design, we explored the development of ToM in 3- to 5-year-old children using an unexpected location task, an unexpected content task, an appearance-reality task, and mothers' MST during mother-child reading. The results showed the following: (1) the mothers' MST exhibited a shift from a predilection for subjective terms (such as desires) to a preference for objective terms (such as cognitions) as their children matured; (2) the development of the children's ToM was closely related to their mothers' MST. The overall MST scores, as well as the different categories and referents used in MST, were closely associated with the children's ToM development. Notably, at the age of four, a critical period emerged where the correlation between maternal MST and ToM became significantly pronounced. These findings highlight the reciprocal nature of mother-child interactions as a two-way adaptive process.

Parents' mental state language and child gender: A scoping review of developmental evidence

Mental state language (MSL) is an important mechanism through which children learn about their social world and place within it. Previous research has suggested that parents may use MSL differently towards children based on their child's gender. However, findings are inconsistent. This scoping review explores the consistency of reported differences in parents' MSL use as a function of children's gender while exploring the methodological variables that may provide insights into these differences. Based on a review of the 27 studies included, 12 found a significant relationship between child gender and parents' MSL, while the remaining did not. The included studies used a range of methodological approaches to elicit MSL. This scoping review allows researchers and practitioners to reflect upon assumptions regarding the associations between child gender and parents' MSL. Further, we call for the use of diverse and informed approaches when studying these associations from a developmental perspective in the future.

A smartphone app effectively facilitates mothers' mind-mindedness: A randomized controlled trial

The efficacy of a smartphone app intervention (BabyMind©) in facilitating mind-mindedness was investigated in a randomized controlled trial, assigning mothers and their 6-month-olds (N = 152; 72 girls, 146 White) to intervention or active control conditions. Mothers who had received the BabyMind© app intervention scored higher for appropriate (d = .61, 95% CI .28, .94) and lower for non-attuned (d = -.55, 95% CI -.92, -.18) mind-related comments at follow-up (age 12 months), compared with their control group counterparts. Adjusting for missing data did not alter this pattern of findings. Mothers' baseline parental reflective functioning did not moderate these relations. Results are discussed in terms of the benefits of early intervention and exploring the efficacy of the app in more diverse populations.

Maternal mind-mindedness over infants' first three months

Maternal mind-mindedness refers to mothers' ability to reflect upon their infants' mental states and respond appropriately. The present study assessed mind-mindedness longitudinally from the newborn period to the infant age of three months. The study is the first to assess maternal mind-mindedness in the infant's early life prior to three months (one week, one month, two months, three months). To measure maternal mind-mindedness, mothers' speech to their infants is coded for mental state comments about the infants' thoughts, desires, and emotions. Appropriate mind-minded comments are judged to accurately reflect the infants' mental states; non-attuned mind-minded comments are judged to misinterpret the infants' mental states. Mothers' individual stability (rank order stability) and group level continuity (mean level of stability across the infant ages) were assessed. Mothers showed modest temporal stability in both appropriate and non-attuned mind-mindedness over the infants' first three months. The continuity of mind-mindedness showed that appropriate mind-mindedness increased over the infant ages, but non-attuned mind-mindedness showed no change. In infants' early lives, mothers' ability to accurately interpret their infants' mental states is enhanced as the mother-infant relationship develops and infants become more communicative partners.

Longitudinal associations between mother-child attachment security in toddlerhood and white matter microstructure in late childhood: a preliminary investigation

Early childhood experiences are considered to influence the strength and effectiveness of neural connections and thus the development of brain connectivity. As one of the most pervasive and potent early relational experiences, parent-child attachment is a prime candidate to account for experience-driven differences in brain development. Yet, knowledge of the effects of parent-child attachment on brain structure in typically developing children is scarce and largely limited to grey matter, whereas caregiving influences on white matter (i.e. neural connections) have seldom been explored. This study examined whether normative variation in mother-child attachment security predicts white matter microstructure in late childhood and explored associations with cognitive-inhibition. Mother-child attachment security was assessed using home observations when children (N = 32, 20 girls) were 15 and 26 months old. White matter microstructure was assessed using diffusion magnetic resonance imaging when children were 10 years old. Child cognitive-inhibition was tested when children were 11 years old. Results revealed a negative association between mother-toddler attachment security and child white matter microstructure organization, which in turn related to better child cognitive-inhibition. While preliminary given the sample size, these findings add to the growing literature that suggests that rich and positive experiences are likely to decelerate brain development.

Associations Between Parent Mental State Language and Child Inhibitory Control in Children Who Are Deaf or Hard of Hearing

PURPOSE

Children who are deaf or hard of hearing (D/HH) are at increased risk for neurocognitive delays, which can have cascading effects on development. Associations between neurocognition and the content of parental language-specifically the use of mental state vocabulary-have been observed in typically hearing (TH) children. This study investigated the role of parental use of mental state language (e.g., vocabulary related to thought processes, desires, and emotions) in explaining variability in neurocognition in children who are D/HH.

METHOD

Dyads of 62 TH and 69 D/HH children who wear hearing aids or cochlear implants (ages 3-8 years) and their primary parent were videorecorded during a 20-min play session. Specific mental state words used by parents were extracted. Child neurocognition (specifically, inhibitory control) was assessed using norm-referenced measures.

RESULTS

Parent use of mental state language predicted child inhibitory control differentially based on hearing status, with a significant relation in the D/HH but not the TH group. Mental state vocabulary related to cognition (e.g., "think," "know"), but not to desire (e.g., "want," "like") or emotion (e.g., "feel," "frustrated"), predicted child inhibitory control in the D/HH group. Finally, there was a significant relation between the use of first person, but not second or third person, mental state verbs (e.g., "I think") and child inhibitory control.

CONCLUSIONS

Parental use of cognitive mental state vocabulary models language around thought processes, and parents' use of first-person referents models "self-talk." Modeling of these linguistic forms is likely foundational for developing self-regulation. Children who are D/HH often experience reduced auditory access and/or language delays and thus rely on high-quality parental language input for longer periods of development than their TH peers. Continued support from interventionists is indicated to coach parents to be high-quality models of more abstract, decontextualized language, supporting complex language development and inhibitory control in children who are D/HH.

Maternal mind-mindedness and communicative functions in free-play and mealtime contexts: Stability, continuity and relations with child language at 16 months

The present study aimed at investigating the contextual stability, the contextual continuity and the concurrent associations between maternal measures (general language, communicative functions and mind-mindedness) and child measures (total number of word types and tokens) in two different contexts, free-play and mealtime. To this purpose, the interactions occurring between 25 mothers and their 16-month-old children in each context were video-recorded, transcribed and later coded for the selected measures. Significant contextual stability was observed in the mothers' production of general language measures (total number of utterances, total number of words and MLU), in the children's production of word types and tokens, and in some communicative functions (Tutorial, Control and Asynchronous). No contextual stability was found for the mothers' production of attuned mind-related comments. For continuity, both mothers and children produced more utterances and words in the free-play than in the mealtime context; the production of attuned mind-related comments and the use of the Control function were also more frequent in the free-play context. Lastly, the analysis of the concurrent correlations indicated that, especially in the mealtime context, the number of words produced by children was positively associated with the number of words produced by mothers and by their use of the Tutorial and Didactic functions, but negatively associated with their use of the Control function. The mothers' production of attuned mind-related comments bore no relation with children's expressive language. Similarities and differences with previous findings are discussed.

Caregivers' mind-mindedness and rural left-behind young children's insecure attachment: The moderated mediation model of theory of mind and family status

BACKGROUND

China's rapid development and urbanization since the early 1980s have compelled many rural residents to move from rural to urban areas for work, leaving thousands of children at home.

OBJECTIVE

This study tested the mediating effect of children's theory of mind on the relationship between caregivers' mind-mindedness and their children's insecure attachment differently depending on the different family status (the moderator) of left-behind and non-left-behind.

PARTICIPANTS

The participants were 3 to 6 years old 74 left-behind children (LBHC) and 89 non-left-behind children (NLBHC).

SETTINGS

Participants were from rural counties of central China in Henan province that has experienced a large labor migration.

METHODS

A cross-sectional moderated mediation model linked mind-mindedness (independent variable) and insecure attachment (dependent variable) through the theory of mind (mediator) and family status (moderator: left-behind/non-left-behind), controlling for age, gender, and siblings.

RESULTS

First, LBHC scored higher on insecure-disorganized attachment than NLBHC. Second, the early childhood theory of mind mediated the relationship between the caregiver's mind-mindedness and young children's insecure attachment. Third, family status moderated the effects of the theory of mind on insecure attachment. The mediating role was established only for the left-behind family, and the lower theory of mind ability was associated with the greater insecure attachment of LBHC.

CONCLUSIONS

Our findings highlight the critical role of mind-mindedness, theory of mind, and family status in the attachment theory and clarify the association between different levels of young children's theory of mind and insecure attachment based on family status.

Parental reflective functioning and theory of mind acquisition: A developmental perspective

This study investigated theory of mind (ToM) development in 83 children aged 3-5 years and its associations with parental reflective functioning (PRF), using a multidimensional and developmental approach. Results showed that ToM dimensions (i.e., affective, belief-desire, and cognitive) gradually increased with age. All dimensions of PRF (i.e., prementalizing modes, certainty about mental states, and interest and curiosity in mental states) were associated with ToM dimensions, with different dimensions being differentially related to ToM, including age-related effects.

Imagining the baby: Neural reactivity to infant distress and mind-mindedness in expectant parents

Neural and psychological processes in pregnancy may be important antecedents for caregiving postpartum. Employing event-related potentials, we examined neural reactivity to infant emotional faces during the third trimester of pregnancy in expectant mothers (n = 38) and expectant fathers (n = 30). Specifically, expectant parents viewed infant distress and infant neutral faces while electroencephalography was simultaneously recorded. As a psychological measure, we assessed prenatal mind-mindedness towards the unborn child and examined whether neural processing of infant cues was associated with levels of mind-mindedness. Expectant fathers evidenced greater P300 reactivity to infant distress, relative to neutral, faces than expectant mothers. Furthermore, P300 reactivity to infant distress, relative to infant neutral, faces was associated with levels of prenatal mind-mindedness in expectant fathers but not expectant mothers. These findings indicate significant sex differences in the prenatal neural processing of infant cues and relations between neural reactivity to infant distress and the emergence of parental mind-mindedness.

A Preliminary Investigation Into a Range of Implicit and Explicit Offense Supportive Cognitions in Perpetrators of Physical Intimate Partner Violence

The current study assessed a wide range of offense supportive cognitions in relation to the perpetration of physical intimate partner violence (IPV). This research used both implicit and explicit measures in a U.K. sample of 19 male IPV perpetrators recruited from a community-based IPV intervention program and 20 men from the community with no history of IPV. The study also explored the ability of the implicit measures to differentiate between the two groups. The cognitions assessed included gender-role stereotype, attitudes condoning violence against a partner, attitudes condoning violence in general, hostile attitudes toward women, sense of entitlement in the relationship and over the intimate partner (control and dominance), and general sense of entitlement. Participants completed a number of established self-report measures and a series of computer-based reaction time tasks including two implicit association tests, one go/no-go association task, and four sentence judgment tasks. Significant group differences emerged across all measures both at the explicit and at the implicit level. Most implicit measures had very good discriminatory power, and the combination of all implicit measures showed excellent discriminatory power, equal to that of the explicit measures combined. These findings suggest that some IPV perpetrators hold offense supportive cognitions that may have become fairly well established and have started to operate at an automatic level. Implicit measures could be useful tools for risk assessment purposes and identification of treatment needs alongside already established measures.

Mind-mindedness in out-of-home Care for Children: Implications for caregivers and child

Most out-of-home placed children have experienced early adversities, including maltreatment and neglect. A challenge for caregivers is to adequately interpret their foster child’s internal mental states and behavior. We examined caregivers’ mind-mindedness in out-of-home care, and the association among caregivers’ mind-mindedness (and its positive, neutral, and negative valence), recognition of the child’s trauma symptoms, and behavior problems. Participants (N = 138) were foster parents, family-home parents, and residential care workers. Caregivers’ mind-mindedness was assessed with the describe-your-child measure. Caregivers’ recognition of the child’s trauma symptoms, their child’s emotional symptoms, conduct problems, prosocial behavior, and quality of the caregiver-child relationship were assessed using caregivers’ reports. Foster parents produced more mental-state descriptors than did residential care workers. General mind-mindedness, as well as neutral and positive mind-mindedness, related negatively to conduct problems. Besides, positive mind-mindedness was associated with prosocial behavior and neutral mind-mindedness with a better quality of the caregiver-child relationship and fewer child conduct problems. Negative mind-mindedness related positively to the caregiver’s recognition of the child’s trauma symptoms, and indirectly, to emotional symptoms. In conclusion, mind-mindedness seems to be an essential characteristic of out-of-home caregivers, connected to the understanding of their child’s behavior problems and trauma symptoms, as well as to the relationship with the child. The findings suggest a possible use of mind-mindedness in out-of-home care evaluation and intervention.

Mind-mindedness and parenting stress in mothers of preterm and full-term infants: The moderating role of perceived social support

The goal of this study was to examine the effects of preterm birth and maternal childbirth-related posttraumatic stress and parenting stress on maternal mind-mindedness (MM). The study also investigated the effects of perceived social support on parenting stress and MM. Sixty-five preterm (N = 32) and full-term (N = 33) mother-infant dyads were observed at 6 months. Measures of maternal MM were obtained from observations of mother-infant interaction. Mothers also provided ratings of their posttraumatic stress disorder (PTSD) symptoms, parenting stress, and perceived social support via an online survey. Experiencing a preterm birth did not affect mothers' use of mental state descriptors during mother-infant interaction. Neither childbirth-related posttraumatic stress nor parenting stress directly affected maternal ability to comment on the child's mental states appropriately. However, at medium and high levels of perceived social support, a negative association between parenting stress and MM was observed. Maternal perception of being emotionally supported by significant others promoted MM in mothers showing low or mild levels of parenting stress, but not in mothers experiencing high stress in parenting their infants. Results suggest that a proclivity to MM might be affected by the interaction between parenting stress and social support, rather than by childbirth-related variables, such as prematurity.

Association Between Cognitive Function and Early Life Experiences in Patients with Alcohol Use Disorder

INTRODUCTION

Early life experiences could be potential risk factors for the development of alcohol use disorder. In similar circumstances, it might also influence cognitive impairment in later life. However, the relationship between early life experience and cognitive function in people with alcohol use disorders is unclear. The current study examined the effects of early social environments and experiences on cognitive function in patients with alcohol use disorder.

METHODS

A total of 37 adult male patients with alcohol use disorder and 30 healthy control (HC) subjects were enrolled. The MATRICS Cognitive Consensus Battery (MCCB) was used to evaluate cognitive function. The Childhood Trauma Questionnaire (CTQ) and the Revised Adult Attachment Scale (RAAS) were used to evaluate early life experiences of the participants. The RAAS was used to evaluate the attachment patterns of participants.

RESULTS

Compared with the HC group, the alcohol use disorder group reported higher levels of childhood abuse and were more likely to form an insecure attachment style. Patients with alcohol use disorder who experienced trauma performed worse in terms of discrete cognitive parameters such as social cognition, reasoning and problem solving compared to patients without trauma. Importantly, emotional neglect and social comfort were significantly associated with individual social cognitive skills.

CONCLUSIONS

Our results suggest that the cognitive function of patients with alcohol use disorder, especially social cognitive function, is affected by early life experiences.

Exploring the relation between maternal mind-mindedness and children's symbolic play: A longitudinal study from 6 to 18 months

Relations between mothers' mind-mindedness (appropriate attunement to their infants' internal states) at 6 and 12 months and infants' early symbolic play during infant-mother pretense at 12 and 18 months were investigated in a sample of 43 mothers and infants. Mothers' appropriate mind-related comments were associated with average level, length, complexity, and maturity level of symbolic play. Specific sub-categories of appropriate mind-related comments were identified as independent predictors of children's symbolic play. Appropriate comments about desires and cognitions at 6 months were associated with average level and length of episodes, as well as with maturity level of symbolic play at 12 months. Longitudinal stability in the appropriateness and content of mothers' mind-related comments was also investigated. The results are discussed in terms of the proposal that attunement to specific types of internal state should vary as a function of infant age in order to index mind-mindedness.

Brain Responses to Emotional Infant Faces in New Mothers and Nulliparous Women

The experience of motherhood is one of the most salient events in a woman’s life. Motherhood is associated with a series of neurophysiological, psychological, and behavioral changes that allow women to better adapt to their new role as mothers. Infants communicate their needs and physiological states mainly through salient emotional expressions, and maternal responses to infant signals are critical for infant survival and development. In this study, we investigated the whole brain functional response to emotional infant faces in 20 new mothers and 22 nulliparous women during functional magnetic resonance imaging scans. New mothers showed higher brain activation in regions involved in infant facial expression processing and empathic and mentalizing networks than nulliparous women. Furthermore, magnitudes of the activation of the left parahippocampal gyrus and the left fusiform gyrus, recruited during facial expression processing, were positively correlated with empathic concern (EC) scores in new mothers when viewing emotional (happy-sad) faces contrasted to neutral faces. Taken together, these results indicate that the experience of being a mother affects human brain responses in visual and social cognitive brain areas and in brain areas associated with theory-of-mind related and empathic processing.

Children's theory of mind as a mechanism linking parents' mind-mindedness in infancy with children's conscience

Growing research on parental mind-mindedness has revealed significant positive associations between parents' appropriate mind-minded (MM) comments to their infants and children's future theory of mind (ToM). In turn, ToM has been broadly linked with a range of social-moral competencies. However, few (if any) studies have examined long-term paths from mothers' and fathers' mind-mindedness in infancy to conscience at early school age, with ToM serving as a mediator of those links. We tested such a model in a prospective longitudinal study of 102 community infants, mothers, and fathers. Parents' MM comments to their infants were coded in naturalistic interactions in snack and play contexts at 7 months. Children's ToM was assessed in false-belief tasks at 4.5 and 5.5 years, and two aspects of their conscience were assessed at 6.5 years: discomfort following transgressions and prosocial judgments in hypothetical moral dilemmas. We tested our model in a comprehensive path analysis that accounted for developmental continuity of both aspects of conscience. Children's ToM was positively associated with both measures of future conscience. The long-term paths from parental mind-mindedness in infancy to conscience were found for mother-child relationships only. For mothers and children, we supported the paths from maternal appropriate MM comments during a snack context in infancy to both aspects of children's conscience mediated by children's ToM. The findings extend earlier evidence suggesting the potentially important role of the parent-child interactive context for long-term effects of early parental mind-mindedness and highlight differences in the roles MM comments may play in mother-child and father-child relationships.

Fathers' and Mothers' Early Mind-Mindedness Predicts Social Competence and Behavior Problems in Childhood

Parental mind-mindedness, the parent's propensity to treat the child as an intentional agent, has repeatedly shown to promote children's development of social understanding and secure attachment. Less is known about whether the impact of maternal and paternal mind-mindedness extends to children's social and behavior problems. We investigated the combined effect of mothers' and fathers' (N = 104) mind-mindedness at 4, 12, and 30 months on children's social competence and externalizing and internalizing behavior problems at 4.5 years. Besides, we examined the stability, continuity, parental concordance, and inter-parental differences in the use of mind-related comments. Appropriate mind-mindedness (i.e., correct interpretations of the child's mental states) and nonattuned mind-mindedness (i.e., misinterpretations of the child's mental states) were observed during parent-child free-play interactions. Social competence, internalizing and externalizing behavior problems were assessed using both parents' reports. Hierarchical multiple regression analyses showed that, at 12 months, infrequent use of appropriate mind-related comments of both parents predicted children's externalizing problems, while their frequent use of nonattuned comments predicted children's low social competence. Furthermore, mothers' frequent use of nonattuned comments at 12 and 30 months and fathers' nonattuned comments at 30 months predicted children's externalizing behavior. The findings suggest that both parents' low use of mind-related comments, and frequent misinterpretations of their child's mind, may act as risk factors for later social and behavior problems of their child.

Proof of concept of a smartphone app to support delivery of an intervention to facilitate mothers' mind-mindedness

The present study reports on the first evaluation of a parenting intervention utilizing a smartphone app, BabyMind. The intervention aimed to facilitate mothers' mind-mindedness-attunement to their infants' internal states. Mothers in the intervention group (n = 90) used the BabyMind app from their infants' births and were followed up at age 6 months (n = 66). Mothers in the control group (n = 151) were recruited when their infants were age 6 months and had never used the BabyMind app. Mind-mindedness when interacting with their infants was significantly higher in intervention group mothers than in control group mothers. The intervention was equally effective in facilitating mind-mindedness in young and older mothers. These findings are discussed in terms of the potential for interventions utilizing smartphone apps to improve parenting and children's developmental outcome in vulnerable and hard-to-reach groups.

[Strengthening Attachment Competencies in Parents with Mental Illness: Adaptation and Pilot Testing of the Mentalization-Based Lighthouse Parenting Program]

Strengthening Attachment Competencies in Parents with Mental Illness: Adaptation and Pilot Testing of the Mentalization-Based Lighthouse Parenting Program Mentalizing describes the imaginative ability to understand human behaviour in terms of mental states. Parents with mental illnesses and experiences of early maltreatment frequently show impairments in mentalizing, which negatively impact their caregiving competences for the child. A number of mentalization-based programs to strengthen parental competences have been developed and most of them have been positively evaluated with regard to their efficacy. However, approaches which specifically aim to reach highly impaired families with children from different age groups and which can be implemented in psychiatric settings are currently lacking. The newly adapted mentalization-based Lighthouse-Parenting Program aims to fill this gap and strengthen competences of parents with a mental illness. The specific MBT-based stance, the structure and content of this new program are outlined and first results of a pilot test are presented. The program is a promising approach, which can easily be trained and implemented in existing mental health care systems. The Lighthouse-Parenting Program aims to improve the relationship between parent and child, to reduce parental stress and in the long-term to promote the child's development. A randomized controlled trial to evaluate the program's effectiveness is currently being planned.

Long-term sequelae of mothers' and fathers' mind-mindedness in infancy: A developmental path to children's attachment at age 10

Rapidly growing research on parental mind-mindedness, a tendency to treat one's young child as a psychological agent and an individual with a mind, internal mental states, and emotions, has demonstrated significant links among parents' mind-mindedness, their parenting, and multiple aspects of children's development. This prospective longitudinal study of 102 community mothers, fathers, and infants, followed from 7 months to 10 years, contributes to research on mind-mindedness by addressing several existing gaps and limitations. We examine mechanisms that account for associations between parents' early mind-mindedness and children's future attachment security, using robust behavioral measures. Teams of trained observers coded parents' mind-minded comments to their infants at 7 months during naturalistic interactions, parents' responsiveness in naturalistic interactions and in elicited imitation tasks at 15 months, and children's security, using Attachment Q-Set at 2 years and Iowa Attachment Behavioral Coding at 10 years. Sequential mediation analyses supported a model of a developmental path from parents' appropriate mind-minded comments in infancy to children's security at age 10. For mothers and children, the path was mediated first through responsiveness at 15 months and then security at 2 years. For fathers and children, the path was mediated through attachment security at 2 years. Parents' nonattuned mind-minded comments had no effects on responsiveness or security.

Does childhood trauma predict poorer metacognitive abilities in people with first-episode psychosis?

Research suggests that people with first-episode psychosis (FEP) report more childhood traumas and have lower metacognitive abilities than non-clinical controls. Childhood trauma negatively affects metacognitive development in population studies, while the association remains largely unexplored in FEP populations. Metacognition refers to the identification of thoughts and feelings and the formation of complex ideas about oneself and others. This study hypothesized that childhood trauma would be associated with lower metacognitive abilities in people with FEP. In a representative sample of 92 persons with non-affective FEP, we assessed childhood trauma, metacognitive abilities and symptoms of psychosis. We used the Childhood Trauma Questionnaire (CTQ) and the Metacognitive Assessment Scale--Abbreviated which includes Self-reflectivity, Awareness of the Mind of the Other, Decentration and Mastery. Hierarchical regression analyses were performed with metacognitive domains as outcome variables and childhood traumas as independent variables, while controlling for age, gender, first-degree psychiatric illness and negative symptoms. We found few significant associations between the different types of childhood trauma and metacognitive domains, and they suggested childhood trauma are associated with better metacognitive abilities. Study limitations included the cross-sectional design and use of self-report measures. Future studies could preferably be prospective and include different measures of psychopathology and neuropsychology.

Predisposing Factors for Elevated Restricted and Repetitive Behavior in Typically Developing Toddlers

Little is known about the relation between levels of restricted and repetitive behavior (RRB) in infants and parent factors. The present study investigated maternal and psychosocial factors (depressive symptoms, socio-economic status, social support) and mother-infant engagement factors (mind-mindedness, sensitivity, and infant-mother attachment security) as predictors of children's RRB at age 26 months in a sample of 206 mothers and children. Maternal depressive symptoms predicted levels of sensory and motor repetitive behavior and rigid, routinized, and ritualistic repetitive behavior. Lower socioeconomic status also predicted independent variance in children's sensory and motor repetitive behavior. The relations between maternal depressive symptoms and both types of RRB were not mediated through observational measures of maternal sensitivity or mind-mindedness at 8 months, or attachment security at 15 months. The results are discussed in terms of whether stress regulation, self-stimulation, and genetic susceptibility can help explain the observed link between maternal depressive symptoms and RRB in the child.

Speaking Your Mind: Language and Narrative in Young Children's Theory of Mind Development

Research consistently finds that language and theory of mind are interrelated. The content and qualities of language that specifically predict theory of mind remain under investigation and the question of why language might impact theory of mind development is open. In this chapter we analyze and highlight current findings and theory addressing theory of mind and language. The principal focus is upon typically developing children between ages 2 and 5, a period characterized by extensive development in language and social understanding. We propose that the study of young children's narrative development can inform how and why language and theory of mind are connected. False belief understanding and narrative comprehension share many similarities and this association provides a promising avenue for future work.

[Parental Reflective Functioning and its Relation to Parenting Stress in a Sample with Early Regulatory Disorders]

Parental Reflective Functioning and its Relation to Parenting Stress in a Sample with Early Regulatory Disorders Parents' capacity to reflect on their child as a mental agent, is defined as an important competence for the early parent-infant relationship. One way to operationalize this is parental reflective functioning (PRF) that distinguishes between mentalizing and non-mentalizing modes of reflection. Until today PRF has not been investigated in samples of infants/toddlers with early regulatory disorders. Goal of the present study is to investigate PRF by comparing a clinical group with parents of infants/toddlers with early regulatory disorders (N = 98) with a healthy control group (N = 27) and testing if PRF is related to parenting stress, past mental illness of the mother, and stress factors related to pregnancy and birth. A semi-structured clinical interview, the Parenting Stress Index, the Symptom-Check-List-90R-S, the Parental Reflective Functioning Questionnaire, and an anamnestic questionnaire were used. Compared to the control group, mothers of infants/toddlers with early regulatory disorders reported significant more prementalizing. Prementalizing in the total sample was significantly predicted by parenting stress, accounting for 16.3 % of the variance. None of the other independent variables significantly predicted prementalizing. Results are discussed in relation to early regulatory disorders and implications for clinical practice.

Does Parental Mind-Mindedness Account for Cross-Cultural Differences in Preschoolers' Theory of Mind?

This study of 241 parent-child dyads from the United Kingdom (N = 120, Mage  = 3.92, SD = 0.53) and Hong Kong (N = 121, Mage  = 3.99, SD = 0.50) breaks new ground by adopting a cross-cultural approach to investigate children's theory of mind and parental mind-mindedness. Relative to the Hong Kong sample, U.K. children showed superior theory-of-mind performance and U.K. parents showed greater levels of mind-mindedness. Within both cultures parental mind-mindedness was correlated with theory of mind. Mind-mindedness also accounted for cultural differences in preschoolers' theory of mind. We argue that children's family environments might shed light on how culture shapes children's theory of mind.

Theory of mind as a link between oxytocin and maternal behavior

BACKGROUND

Oxytocin is a neuropeptide associated with maternal behavior. However the mechanisms underlying this link remain unclear. In a previous study we observed an indirect effect of increased plasma oxytocin during late pregnancy on early postpartum maternal interactive behavior via theory of mind, as assessed by the Reading the Mind in the Eyes Test (RMET). The current study aimed to extend these findings by testing whether this indirect effect would hold longitudinally for maternal behavior at 2-3 years postpartum, as well as for an additional observational measure of maternal mind-mindedness.

METHOD

The original sample of 316 pregnant women (M_age = 31.92 years) was assessed at 12-14 weeks gestation (T1), 32-34 weeks gestation (T2), and 7-9 weeks postpartum (T3). Follow-up measures were taken at 2-3 years postpartum (T4).

RESULTS

Mothers' RMET performance (T3) was associated with more structuring and less intrusive maternal behavior at 2-3 years (T4), while their tendency to use mind-related comments (T3) was associated with greater sensitivity (T4). Bootstrap estimates also revealed a significant indirect effect of plasma oxytocin levels during late pregnancy (T2) on maternal structuring and non-intrusive behavior at 2-3 years postpartum (T4) through RMET performance (T3).

CONCLUSIONS

Results: of the current study confirm and extend the previous findings, demonstrating that theory of mind may represent a social cognitive mechanism linking endogenous oxytocin and maternal behavior. Important changes in the oxytocinergic system during late pregnancy may help prepare for motherhood by promoting the awareness of social cues, which in turn promote maternal behavior from the early postpartum to the early childhood years.

Theory-of-Mind Development and Early Sibling Relationships after the Birth of a Sibling: Parental Discipline Matters

This study investigated relations among children's Theory-of-Mind (ToM) development, early sibling interactions, and parental discipline strategies during the transition to siblinghood. Using a sample of firstborn children and their parents (N = 208), we assessed children's ToM before the birth of a sibling and 12 months after the birth, and sibling interactions (i.e., positive engagement and antagonism) and parental discipline strategies (i.e., child-centred and parent-centred discipline) at 4 and 8 months in the first year of siblinghood. Structural equation modelling analyses revealed that children's ToM before the birth of the sibling predicted children's positive engagement with the infant sibling, whereas children's antagonistic behaviours towards the infant sibling negatively predicted children's ToM at 12 months, but only when mothers used low levels of child-centred discipline. These findings emphasize the role of parents in the development of young children's social- cognitive understanding in the context of sibling interactions even as early as the first year after the sibling's birth.

Mothers' Early Mind-Mindedness Predicts Educational Attainment in Socially and Economically Disadvantaged British Children

Relations between mothers' mind-mindedness (appropriate and nonattuned mind-related comments) at 8 months (N = 206), and children's educational attainment at ages 7 (n = 158) and 11 (n = 156) were investigated in a British sample. Appropriate mind-related comments were positively correlated with reading and mathematics performance at both ages but only in the low-socioeconomic status (SES) group. Path analyses showed that in the low-SES group, appropriate mind-related comments directly predicted age-11 reading performance, with age-4 verbal ability mediating the relation between appropriate mind-related comments and age-7 reading. In contrast, maternal sensitivity and infant-mother attachment security did not predict children's educational attainment. These findings are discussed in terms of genetic and environmental contributions to reading and mathematics performance.

Maternal communicative functions and mind-mindedness at 16 months as predictors of children's internal and non-internal language at 20 months

The effects of Communicative functions and Mind-Mindedness on children's language development have been typically investigated in separate studies. The present longitudinal research was therefore designed to yield new insight into the simultaneous impact of these two dimensions of maternal responsiveness on the acquisition of expressive language skills in a sample of 25 mother-child dyads. The frequencies of five communicative functions (Tutorial, Didactic, Conversational, Control and Asynchronous) and two types of mind-related comments (attuned vs. non-attuned) were assessed from a 15-min play session at 16 months. Children's expressive language was examined at both 16 months (number of word types and tokens produced, and number of words attributed to the child in the Questionnaire for Communication and Early Language development) and 20 months (number of internal and non-internal words attributed to the child in the Italian version of the Mac Arthur-Bates Communicative Development Inventory). The main finding was that mothers' use of attuned mind-related comments at 16 months predicted internal state language at 20 months, above and beyond the effects of CFs and children's linguistic ability at 16 months; in addition, mothers' Tutorial function at 16 months marginally predicted non-internal state language at 20 months, after controlling for MM and children's linguistic ability at 16 months. These results suggest that different expressions of maternal responsiveness influence distinct aspects of children's expressive language in the second year of life, although the effects of MM appear to be more robust.

Let's Talk: Parents' Mental Talk (Not Mind-Mindedness or Mindreading Capacity) Predicts Children's False Belief Understanding

Although one might expect parents' mind-mindedness (MM; the propensity to view children as mental agents) to relate to everyday mental-state talk (MST) and theory-of-mind capacity, evidence to support this view is lacking. In addition, both the uniqueness and the specificity of relations between parental MM, parental MST, and children's false belief understanding (FBU) are open to question. To address these three gaps, this study tracked 117 preschoolers (60 boys) and their parents across a 13-month period (M_age  = 3.94 years, SD = 0.53, at Time 1). Parental MM, MST, and theory-of-mind capacity showed little overlap. Both MM and MST were weakly associated with children's concurrent FBU, but in line with social constructivist accounts, only MST predicted later FBU.

Preterm birth enhances the contribution of mothers' mind-mindedness to infants' expressive language development: A longitudinal investigation

Maternal mind-mindedness has been shown to be a powerful predictor of many developmental outcomes and to buffer the impact of psychosocial risk conditions, but no study has investigated whether this parental feature might support child development in the presence of biological risk, such as preterm birth. The present study addresses this gap, by investigating whether early maternal mind-mindedness contributes to the growth of a child's linguistic abilities in the following two years of life, and if the contribution of this maternal feature might be stronger in the presence of preterm birth. Forty mother-child dyads (twenty with a preterm infant) were followed longitudinally, with maternal mind-mindedness assessed at 14 months of age and child's expressive linguistic abilities at 24 and 36 months through observational measures. Multilevel models showed that linguistic abilities increased from 24 to 36 months of age, but that this increase was stronger in full-term infants. Maternal mind-mindedness also contributed to this growth, playing a stronger role in preterm infants than in full-term infants. Altogether, these findings contribute more deeply to the understanding of language development in preterm infants and of the joint contribution made by biological risk and environmental factors; from a practical standpoint, they suggest the importance of addressing mother's mind-mindedness in order to support child's language development.

Proof of concept of a mind-mindedness intervention for mothers hospitalized for severe mental illness

Studies 1 and 2 investigated how maternal severe mental illness (SMI) related to mothers' mind-mindedness (appropriate and nonattuned mind-related comments). Study 1 showed that mothers with SMI (n = 50) scored lower than psychologically well mothers for both appropriate and nonattuned comments, whereas mothers with SMI in Study 2 (n = 22) had elevated levels of nonattuned comments. Study 2 also tested the efficacy of a single-session video-feedback intervention to facilitate mind-mindedness in mothers with SMI. The intervention was associated with a decrease in nonattuned comments, such that on discharge, mothers did not differ from psychologically well controls. Study 3 assessed infant-mother attachment security in a small subset of intervention-group mothers from Study 2 (n = 9) and a separate group of standard care mothers (n = 30) at infant mean age 17.1 months (SD = 2.1). Infants whose mothers completed the intervention were more likely to be securely attached and less likely to be classified as insecure-disorganized than those of mothers who received standard care. We conclude that a single session of video-feedback to facilitate mind-mindedness in mothers with SMI may have benefits for mother-infant interaction into the second year of life.

How do mothers with borderline personality disorder mentalize when interacting with their infants?

Mothers with borderline personality disorder (BPD) have been theorized to have decreased mentalization ability, which is the capacity to perceive and interpret mental states. This could increase the risk for troubled relationships with their infants and therefore have adverse consequences for child social and emotional development. Mind-mindedness (MM), which codes the mother's references to her infant's mental states during an interaction, is one method of indexing mothers' mentalizing ability. However, research has yet to examine MM in mothers with BPD. Our objective was to assess the MM ability of 38 mothers during interactions with their 12-month-old infants, including 10 mothers with BPD and 28 mothers without a psychiatric diagnosis. Trained observers assessed maternal MM from 2 min of videotaped mother-infant free play. BPD was assessed with the Structured Clinical Interview for DSM-III-R-Personality Disorders (SCID-II). Mothers with and without BPD did not differ in the proportion of total comments referring to infant mental states. However, mothers in the BPD group proportionately made 3.6 times more misattuned mind-related comments than control mothers. Thus, mothers with and without BPD appear equally likely to envision mental states in their infants. However, mothers with BPD also appear more likely to misread their infants' mental states.

Prenatal Reflective Functioning and Development of Aggression in Infancy: the Roles of Maternal Intrusiveness and Sensitivity

Maternal reflective functioning (RF) has been associated with quality of parent-child interactions and child development. This study investigated whether prenatal RF predicted the development of infant physical aggression and whether maternal sensitivity and/or intrusiveness mediated or moderated this association. The sample consisted of 96 first-time mothers (M = 22.57 years, SD = 2.13) and their infants (54 % male). Prenatal RF was measured with an interview, maternal behavior was observed during free play at 6 months post-partum, and infant physical aggression was assessed at 6, 12, and 20 months using maternal reports. Multivariate analyses of variance showed that relatively poor prenatal RF was related to relatively high infant physical aggression. These associations were moderated by maternal intrusiveness, with significant differences in physical aggression between RF-groups reportedly only in the absence of intrusiveness. Generally, mothers reported an increase in physical aggression between 6 and 12 months, except when they had both low RF-skills and were relatively less sensitive. It is concluded that prenatal RF is associated with (development of) infant physical aggression, and may be targeted in intervention programs aimed at reducing early physical aggression. Less adequate parenting, however, may counteract the beneficial effects of good RF, or obscure insight into children's behavioral development.
