The effects of mothers' teasing: Do Japanese infants read their mothers' play intention in teasing?

The focus of this study was whether an infant can understand the playful intention in the mother's teasing behaviour. The mother's teasing behaviour can elicit playful interaction with the infant on the one hand, or can result in the infant's distress. In other words, teasing may function as the turning-point in mother-infant interaction. Thus it was hypothesized that the consequence of mothers' teasing behaviour would be positive or negative depending on the success or failure in communication of both mothers' play intention with play signs and infants' interpretation of the play signs. Subjects were 20 mothers and their infants aged from 10 to 13 months (M = 11 months) who were observed during 10 minutes of free play with toys that evoke minor surprise and/or fearfulness. Results showed that about one-third of mothers' teasing behaviour elicited the infant's enjoyment. Especially, mothers' playful teasing accompanied by a smile or laugh led most successfully to infant enjoyment. In contrast, mothers' pretence teasing elicited no particular response from infants. These data suggest that around their first birthday infants develop some understanding of the play intention latent in mothers' teasing behaviour.     

Mothers who are securely attached in pregnancy show more attuned infant mirroring 7 months postpartum

This study contrasted two forms of mother–infant mirroring: the mother's imitation of the infant's facial, gestural, or vocal behavior (i.e., “direct mirroring”) and the mother's ostensive verbalization of the infant's internal state, marked as distinct from the infant's own experience (i.e., “intention mirroring”). Fifty mothers completed the Adult Attachment Interview (Dynamic Maturational Model) during the third trimester of pregnancy. Mothers returned with their infants 7 months postpartum and completed a modified still-face procedure. While direct mirroring did not distinguish between secure and insecure/dismissing mothers, secure mothers were observed to engage in intention mirroring more than twice as frequently as did insecure/dismissing mothers. Infants of the two mother groups also demonstrated differences, with infants of secure mothers directing their attention toward their mothers at a higher frequency than did infants of insecure/dismissing mothers. The findings underscore marked and ostensive verbalization as a distinguishing feature of secure mothers’ well-attuned, affect-mirroring communication with their infants.     

Mother–Infant Joint Attention and Sharing: Relations to Disorganized Attachment and Maternal Disrupted Communication

The normative development of infant shared attention has been studied extensively, but few studies have examined the impact of disorganized attachment and disturbed maternal caregiving on mother–infant shared attention. The authors examined both maternal initiations of joint attention and infants’ responses to those initiations during the reunion episodes of the Strange Situation Procedure at 12 and 18 months of infant age. The mothers' initiations of joint attention and three forms of infant response, including shunning, simple joint attention, and sharing attention, were examined in relation to infant disorganized attachment and maternal disrupted communication. Mothers who were disrupted in communication with their infants at 18 months initiated fewer bids for joint attention at 12 months, and, at 18 months, mothers of infants classified disorganized initiated fewer bids. However, the infant' responses were unrelated to either the infant' or the mother' disturbed attachment. At both ages, disorganized infants and infants of disrupted mothers were as likely to respond to maternal bids as were their lower risk counterparts. Our results suggest that a disposition to share experiences with others is robust in infancy, even among infants with adverse attachment experiences, but this infant disposition may depend on adult initiation of bids to be realized.     

The co‐construction of joint action between mothers and 2–4‐month‐old infants: the mother's role

The purpose of this longitudinal study was to describe object‐centred interactions between mothers and their 2–4‐month‐old infants, before and during the emergence of reaching and grasping movements. We hypothesized that when reaching movements emerge at around 3 months, mothers alternate between attention stimulation and reaching stimulation, before joint actions between mother and infant develop around objects. Twelve dyads were recorded when infants were 2 months, 3 months and 4 months. The interactive sessions lasted 5 min. Three age‐appropriate toys the infant could handle were available to the mother. A principal component analysis (PCA) was performed on verbal and non‐verbal maternal behaviours, motor infant behaviours and co‐occurrences of those behaviours. The developmental course of prehension in infants when playing with their mother follows similar pathways, as was described when they are observed alone. Mothers appeared to early scaffold prehension skills by verbal and non‐verbal means. Moreover, maternal behaviours change according to the infant's behaviour, and conversely, infant's behaviours influence maternal behaviours: mother plays first an active part in joint action, while later on, the infant achieves joint action when motor skills develop.

Maternal correlates of infant temperament ratings and of infant-mother attachment: A longitudinal study

This study examined longitudinally correlates of mothers' ratings of their infant's temperament and of the infant-mother attachment relationship. Measures included Carey's Revised Infant Temperament Questionnaire, child-rearing attitudes, psychophysiological responses to an unfamiliar infant's crying pre- and postdelivery, psychophysiological responses to the mother's own infant's crying, and assessments of infant-mother attachment. The results indicated that maternal ratings of infant temperament at 4 months were significantly related not only to concurrent cry responsiveness but also to cry responsiveness and child-rearing attitudes predelivery, as well as to the quality of attachment at 1 year. It is suggested that a differential response pattern of mothers of “easy” and of “difficult” infants, which affects the developing infant-mother bond, may in part originate in maternal dispositions existing prior to parenthood.     

The song,not the singer: Infants prefer to listen to familiar songs,regardless of singer identity

Parent's infant-directed vocalizations are highly dynamic and emotive compared to their adult-directed counterparts, and correspondingly, more effectively capture infants’ attention. Infant-directed singing is a specific type of vocalization that is common throughout the world. Parents tend to sing a small handful of songs in a stereotyped way, and a number of recent studies have highlighted the significance of familiar songs in young children's social behaviors and evaluations. To date, no studies have examined whether infants’ responses to familiar versus unfamiliar songs are modulated by singer identity (i.e., whether the singer is their own parent). In the present study, we investigated 9- to 12-month-old infants’ (N = 29) behavioral and electrodermal responses to relatively familiar and unfamiliar songs sung by either their own mother or another infant's mother. Familiar songs recruited more attention and rhythmic movement, and lower electrodermal levels relative to unfamiliar songs. Moreover, these responses were robust regardless of whether the singer was their mother or a stranger, even when the stranger's rendition differed greatly from their mothers’ in mean fundamental frequency and tempo. Results indicate that infants’ interest in familiar songs is not limited to idiosyncratic characteristics of their parents’ song renditions, and points to the potential for song as an effective early signifier of group membership.     

The influence of novelty and complexity on exploratory behavior in 12-month-old infants

This study investigated the influence of the novelty of the environment and the novelty and complexity of the objects (toys) it contained on the exploratory behavior of 12-month-old infants. Each infant was given a choice between novel and familiar toys located in two adjacent rooms (toy rooms). The novelty of the objects was manipulated by allowing the infants to play with one set of toys during a 5-min familiarization trial prior to the choice trial. The novetly of the environment was manipulated by allowing some infants to see, enter, and remain in the toy rooms during the familiarization trial. Finally, the complexity of the objects was manipulated by varying the number of familiar and novel toys; some Ss had four toys in each set (complex array) and some had only one (simple array). The results indicate that all three factors influenced the infants' exploratory behavior. Ss first approached, and spent more time manipulating, the novel than the familiar toys; they spent more time in the toy rooms if they were novel; and they spent more time manipulating the complex array of toys than the simple array.     

Evaluation of changes in mother-infant brief psychotherapy: A single case study

Representation-oriented brief psychotherapy with mother-infant dyads is used to examine correspondences between maternal behaviors and maternal representations of her infant. A single case study is presented to illustrate how one can objectify interactional variables that may correspond behaviorally to underlying maternal mental representations. This paper presents the results of a collaboration that focuses on the process of enacting fantasy via the domain of behavior. Attention is drawn to interacted themes that are enacted versions of representational themes. Enacted themes are pathogenic in behavioral terms for the infant. Five themes are identified in the case material. Changes in the mother's representations affect both the mother-infant relationship and the infant's functioning.     

The use of multitreatment modalities in early intervention: A quantitative case study

A quantitative single case study is presented to illustrate how an early intervention program used two therapeutic modalities to treat a depressed mother and her 2-month-old son. Drawing upon an ecological, transactional model of development, the case study utilized a multimethod, longitudinal approach to assess the infant's developmental competence and attachment status, the mother's history and current psychosocial functioning, patterns of mother-infant interaction, and components of the family's social ecology. Measures were administered during a baseline period to assess pre-intervention functioning and were systematically repeated throughout the 2-year period of intervention. The treatment modalities included psychodynamically oriented individual therapy and Parent-Infant Relationship Treatment (PIRT) in which the dyad was also seen by a second therapist to foster more adaptive mother-infant transactional patterns. The findings indicated increased infant developmental competence and a shift from an insecure to a secure attachment classification, improved maternal psychosocial functioning, and a decline in the dyadic interactional pattern of maternal intrusiveness and infant withdrawal. The advantages of using two treatment modalities and a single case approach to evaluation are discussed.     

Number and type of toys affect joint attention of mothers and infants

Establishing joint attention with a caregiver on a physical object provides an optimal environment for language learning for infants. In the present study, we investigated whether 12-month-olds and their mothers establish higher quality joint attention interactions in the presence of fewer compared to more toys. As a secondary goal, we investigated how different types of toys affect how mother-infant dyads establish joint attention. In a five-minute free play setting, mothers and infants participated in either Five Toy (n = 48) or Twelve Toy (n = 33) groups. They were given organizational (i.e., toys that require arrangement of parts), responsive (i.e., toys that emit sounds via manipulation), and symbolic toys (i.e., toys that elicit pretend play). Results showed that compared to the Twelve Toy group, joint attention interactions in the Five Toy group were less frequent, lasted longer, were more likely to be initiated by maternal following than by maternal directing of infants’ attention, and more likely to be coordinated in which infants demonstrated awareness of the mothers’ simultaneous attentional focus by looking at their mothers, vocalizing, or turn-taking. We further found longer joint attention durations on organizational compared to symbolic toys, which were preferred to a lesser extent by the dyads. With responsive toys, mothers were more likely to initiate joint attention by following their infants’ attention. Joint attention interactions lasted longer and were more likely to be coordinated in the second half compared to the first half of the play session, suggesting that over time it became easier for the mothers and infants to settle on certain toys for more elaborate play. In sum, mothers and infants establish higher-quality joint attention with fewer toys in general and with organizational toys in particular.     

Early tactile experience of low birth weight children: links to later mental health and social adaptation

The purpose of this study was twofold: to determine (1) the degree to which specific qualities of maternal touch may contribute to the low birth weight infant's emotional and behavioural problems as well as social adaptation, and (2) the relationship between maternal touch and a mother's other caregiving behaviour. The sample included 114 socioculturally diverse infants and their mothers who were videotaped during an infant feeding when the baby was 3 months old. This videotape was analysed to assess dimensions of mother–infant interaction, including maternal touch. Data on perinatal risk and the mother's acceptance versus rejection of the infant were also acquired. Social adaptation and emotional/behavioural problems were measured when the child was 2 years of age. Hierarchical regression analyses indicated that maternal touch accounted for 15% of the variance in the likelihood of a child having emotional/behavioural problems at age 2. Children who received more nurturing touch had significantly fewer internalizing problems (such as depression) while children receiving both more frequent touch and harsh touch had more externalizing problems (such as aggressive behaviour). Infants who were less responsive to their caregivers were especially at risk of developing aggressive/destructive behaviour as a result of frequent touch. But less responsive infants also appeared to benefit most from greater use of diverse types of maternal touch, accounting for 6% of the variance in superior adaptive behaviour at age 2. Nurturing touch was the only quality that showed even a modest relationship to other caregiving behaviour, suggesting that touch may play a distinct role in the infant's psychosocial development.

Watching,waiting, and wondering: Applying psychoanalytic principals to mother-infant intervention

There is general acceptance that the intergenerational repetition of relational patterns is transmitted within the interactions between mother and infant. The highly invested nature of the mother-infant relationship makes it a prime arena for the playing out of unresolved relational conflicts of the mother. This occurs through the mother's responses to her infant in which she projects into the infant certain disavowed but highly invested positive or negative attributes. This leads to the interactional re-creation of a whole relational system reflecting the mother's current and past relationship experiences. When a mother's conflictual past is unresolved and unmitigated by current relationships, her interactions with her infant are more driven by such perceptions than by real appraisal of the infant's actual attributes. The sleeping, eating, and behavioral management problems of infancy are often manifestations of such situations. A deceptively simple set of instructions to the mother, to become a nonintrusive observer of her infant and only interact at the infant's initiative, allows a role for the infant's initiative in changing interactions and thus potentially changing a relational system.     

Infant's action skill dynamically modulates parental action demonstration in the dyadic interaction

When interacting with infants, human adults modify their behaviours in an exaggerated manner. Previous studies have demonstrated that infant‐directed modification affects the infant's behaviour. However, little is known about how infant‐directed modification is elicited during infant–parent interaction. We investigated whether and how the infant's behaviour affects the mother's action during an interaction. We recorded three‐dimensional information of cup movements while mothers demonstrated a cup‐nesting task during interaction with their infants aged 11 to 13 months. Analyses revealed that spatial characteristics of the mother's task demonstration clearly changed depending on the infant's object manipulation. In particular, the variance in the distance that the cup was moved decreased after the infant's cup nesting and increased after the infant's task‐irrelevant manipulation (e.g. cup banging). This pattern was not observed for mothers with 6‐ to 8‐month‐olds, who do not have the fine motor skill to perform the action. These results indicate that the infant's action skill dynamically affects the infant‐directed action and suggest that the mother is sensitive to the infant's potential to learn a novel action.

Joint attention with the mother and the father at 10 months of age

Joint attention capabilities were assessed in 52 10-month-olds observed independently with their mothers and fathers in a semi-structured toy-play condition. Mothers and fathers were indistinguishable in terms of total number of behaviours aimed at engaging their infant in joint attention. However, infants responded more to mothers' bids for attention than to fathers' bids. Contrastingly, infants tended to display more initiating joint attention behaviours while interacting with their fathers. Although parents did not differ in terms of sensitivity, fathers were less intrusive than mothers. Results are discussed in terms of the specificities of mother-infant and father-infant interaction and how the paternal role should be highlighted in the case of infant's joint attention development.     

Face-to-face interaction behavior across early infancy

Stability and change in mother-infant interaction behavior were assessed across early infancy. At 8 versus 4 months, the infants showed more smiling, vocalizing and motor-activity, and their mothers touched and moved their infants' limbs less often. Stability was noted only for infant distress-brow and mother's touching the infant. Although very few relationships were apparent between mother and infant behavior at 4 months, several maternal behaviors at 4 months were related to infant behaviors at 8 months, and several relationships were noted between maternal and infant behavior at 8 months.     

Infants' responses to mothers' imitative behaviors

Several investigators have suggested that young infants' smiles and vocalizations following their mothers' imitative behaviors might reflect infant recognition that the mother's behavior is imitative or at least contingent. This study investigated whether infants smile and vocalize more frequently subsequent to maternal imitative than non-imitative behavior during both spontaneous and imitative face-to-face interactions. Fourteen 3 1/2-month-old infants and their mothers were videotaped in these two face-to-face interaction situations. The infants vocalized more frequently during the imitative situation and infant vocalizations plus simultaneous smiling, and vocalizations occurred more often following maternal imitative than non-imitative behavior. Although these data suggest that infant vocalizations and simultaneous smiles and vocalizations may reflect the infants' recognition of maternal imitative behavior, they do not establish definitively that it is the imitation per se vs. the contingency aspect that is recognized by the infant.     

Attention-getting vs. imitation effects on depressed mother-infant interactions

The effects of instructing mothers to “imitate” their infant versus “keep their infant's atten tion” were examined during mother-infant face-to-face interactions of 18 mothers reporting depressive symptoms as compared with 22 mothers who did not report such symptoms. Mothers were generally rated as showing more positive facial expressions and more game playing (particularly the depressed mothers) during the attention-getting versus the imitation sessions. The infants received more optimal physical ac tivity, and facial expression ratings during attention getting, and the infants of depressed mothers, in par ticular, showed more positive facial expressivity and more joy expressions. As might be expected for the imitation condition, mothers showed more imitative behavior, contingent responsivity, and silence during gaze aversion. Infants generally showed more disinterest and self-comfort behaviors, and the infants of depressed mothers, in particular, showed more anger expressions, fussiness, and squirming during the imitation condition. The data suggest that the attention-getting condition was the most effective “intervention” for eliciting positive behavior in the depressed mother-infant dyads.     

The social environments of early infancy in Japan and the United States

The social environments of early infancy in Japan and the United States were compared in terms of the context of caregiving and the quality of the month-infant interaction. Mothers of 17 Japanese infants and 17 infants in the United States were interviewed in their homes about the experiences that they provided for their 4-month-old infants, and mother-infant interactions were recorded on videotape. Levels of parents' education were similar in both countries. The context of the infant's development varied substantially with culture. Mothers in the United States provided a greater variety of experiences on the HOME and care of Japanese infants tended to be more exclusively provided by mothers whereas care of infants in the United States was shared by fathers and other caregivers to a greater extent. Examination of behaviour frequencies during mother-infant interaction indicated that mothers in Japan provided their infants with more vocal input and more physical play than mothers in the United States and Japanese mothers were more vocally responsive to their infants' vocalizations.     

Mother's prenatal and postpartum depression symptoms and infant's sleep problems at 6 months

Mother's prenatal and postpartum depression have been associated with infant's sleep problems. This study aimed to analyze (a) the effects of mother's prenatal and postpartum depression symptoms, including the effects of prenatal and postpartum anxiety and depression scores of the Edinburgh Postnatal Depression Scale (EPDS), on infant's sleep problems at 6 months, and (b) the interaction effect between mother's prenatal and postpartum depression symptoms and infant's sex on infant's sleep problems at 6 months. The sample was comprised of 164 mother–infant dyads whose mothers completed measures of depression at the third trimester of pregnancy, 2 weeks, 3 and 6 months postpartum and a measure of infant's sleep problems at 6 months (CSHQ-I). Mother's prenatal depression symptoms, specifically depression scores of the EPDS, predicted more infant's sleep anxiety and daytime sleepiness, while mother's depression symptoms at 2 weeks postpartum, specifically anxiety scores of the EPDS, predicted more bedtime resistance and CSHQ-I total scores at 6 months. Boys of mothers with more prenatal depression symptoms presented more sleep anxiety at 6 months. Both mother's prenatal and early postpartum depression symptoms have a negative effect on the emergence of infant's sleep problems. Additionally, boys seem more vulnerable to mother's prenatal depression symptoms.     

Effects of Labelled Gender on Vocal Communication of Young Women with 4-month-old Infants

Most of the previous studies analyzing the effect of gender label on adults' interactive behaviours with infants concluded that gender stereotypes affect adults' behaviours more than the actual behaviours or characteristics of the infants. These stereotypes and their ensuing behaviours would contribute to the differential socialization experiences of infants according to their gender. The objective of the present study was to investigate further the effect of gender label on adults' vocal communication with infants. Therefore, the prosodic and content features of the language addressed by young women to infants presented as girls and as boys were examined. Sixteen women were observed during two 5-minute sessions of face-to-face interaction with 3-to-4-month-old infants, one introduced as a girl, the other as a boy, in a counterbalanced order. Six girls and four boys served as stimuli. The number of utterances addressed to the infants, their duration and fundamental frequency, as well as the prosodic contour and the content of each vocalization were measured. Results indicated only one significant gender label effect: Women referred more frequently to infant's global motor activity when the infant was presented as a boy. This observation is congruent with other data. However, our results do not demonstrate a consistent pattern of gender label effect when women are talking to unfamiliar infants in such a context.
