Infants at Social Risk: Maternal Depression and Family Support Services as Mediators of Infant Development and Security of Attachment

31 infants at high social risk due to the combined effects of poverty, maternal depression, and caretaking inadequacy were assigned to weekly home-visiting services. At 18 months infant age, the home-visited infants were compared with 2 groups of socioeconomically similar unserved infants on measures of infant development, infant attachment, mother-infant interaction, maternal depression, and maternal social contacts. Home-visited infants of depressed mothers outperformed unserved infants of depressed mothers by an average of 10 points on the Bayley Mental Scale and were twice as likely to be classified as securely attached, with unserved high-risk infants showing a high rate of insecure-disorganized attachments. Duration of services was positively correlated with maternal involvement at 12 months. Results of the study point both to the negative developmental consequences associated with severe social risk conditions and to the buffering effects of developmentally oriented home-visiting services for infants at greatest social risk.     

Prematurity stereotyping: effects on mother-infant interaction

The possibility that the self-fulfilling prophecy process can adversely affect the caregiving environment of premature infants was explored in this study. A portion of this process was investigated experimentally by assessing cognitive and behavioral reactions of 27 mothers to unfamiliar full-term infants who were labeled either full-term or premature. Infants who were described as premature were touched less and given a more immature toy to play with, were rated as smaller, finer-featured, and less cute, and were liked less than infants who were labeled full-term. In turn, infants labeled premature were less active during the interaction than infants labeled full-term. College students who later observed the videotapes made of the mother-infant interactions were able to accurately guess which label was assigned to the infants. The results of this study further support the existence of a prematurity stereotype and the impact of expectations on perceptions and behavior.     

Scaffolding Infants’ Play Through Empowering and Individualizing Teaching Practices

Research Findings: Using a qualitative research approach, this article explores teachers’ roles as scaffolders of infants’ play and the changing nature of their individualized support for infants’ learning and development through play in an infant group care setting. Three infant teachers in a child care center were followed over 3 months. Observations, interviews, ongoing conversations, e-mails, and reflective notes were used as data sources. Findings revealed that the teachers thought deeply about their roles as supporters of infants’ play, and they made intentional choices in scaffolding infants’ play. Each teacher's ways of empowering infants in play were grounded in her views of infants as learners and were individualized to accommodate children's unique learning styles and personalities. Practice or Policy: This study provides a window into the ways in which teachers working with the youngest children can set the stage for later learning.     

Infants entering foster care compared to other infants using birth status indicators

Objective: Infants comprise nearly one fourth of all entries to foster care. Linkage of administrative birth and placement data can provide information about these infants that may otherwise be unavailable or difficult to obtain.Method: Statewide birth records and foster care placement histories were linked via probability matching. Logit regression was used to compare 26,460 maltreated infants who entered foster care between 1989 and 1994 with a random sample of 68,401 other infants born during that time frame.Results: Infants in care were more than twice as likely to have single parents and be born with low birthweight, and twice as likely to have been born with a birth abnormality as other infants, controlling for other factors. The largest difference was in the eightfold increased likelihood for mothers of infants in care to have had no prenatal care. Infants in care were nearly three times as likely to be born into larger families (third or greater live births to the mother). Mothers of infants in care were more than twice as likely to be African American compared to White than mothers of other infants, while Hispanic and Other ethnic groups were underrepresented in the group of infants in care. Foreign born mothers, especially Hispanic women, were much less likely to have infants in care than they were to have children in the other group.Conclusions: Administrative datasets, while often limited in the number of variables they include and scope of their information, can be a valuable tool when used to understand demographics and frame questions for future research. Infants who enter foster care differ in substantial ways from other children. These findings have important implications for future research aimed toward targeting of child welfare services and supports.     

Early childhood educators’ conceptions of infants’ capabilities: the nexus between beliefs and practice

The conceptions early childhood educators (ECEs) hold about infants can guide their pedagogical practices in ways that can enable and constrain infants’ experiences. Literature regarding infants’ development and the role of adults in infant learning theoretically positions infants as both being capable of independent learning, and needing adult intervention and involvement. However, there is a paucity of research about ECEs’ understandings of infants’ capabilities, and how these conceptions influence their practices with babies. Using the theory of practice architectures as a methodological and analytical framework, this study collaboratively examines the ways educators’ conceptions are influenced by cultural-discursive arrangements of the site, and identifies the ensuing practices. The findings show that educators held conceptions of infants as more capable of independently directing their own physical and cognitive learning, and as more dependent on educators for emotional and social learning. Considering infants as both more and less capable is discussed, and implications of how the practices might enable and constrain infants’ learning are explored.     

Fathers' involvement in the care of their infants and their attributions of cognitive competence to infants

The relation between fathers' involvement in the care of their infants and their attributions of cognitive-social skills to infants was investigated in this study. 160 pairs of parents of 9-month-old infants were interviewed. On the average, fathers were available to their infants 2.75 hours per weekday and spent 45-50 min interacting with them. They performed 1 caretaking activity per day, and took sole responsibility for the infant only about once in 10 days. Results indicate that fathers who are less involved in child care attribute lesser competence to infants than relatively more involved fathers, that fathers in general attribute lesser competence to infants than mothers, and that the more involved a father is in infant care, the less difference there is between his attributions and those of his wife's. These results raise the possibility that involvement in care and perception of infants as cognitively competent are mutually reinforcing.     

Biobehavioral Organization in Securely and Insecurely Attached Infants

Attachment research has shown the emergence of individual differences in the security of infant-mother attachment during the first year of life as well as their importance for later social-emotional development. A biobehavioral perspective may help settle disagreements about the validity and interpretation of 12-month-old infants' different behavioral patterns of attachment assessed by Ainsworth's Strange Situation. It was shown that, despite less overt distress in insecure-avoidant infants after short separations from the mother, overall cardiac measures indicate arousal patterns similar to the secure infants during separation. However, differences in cardiac response emerged with regard to object versus person orientation during reunion. Additionally, findings of increased cortisol in both insecure-avoidant and disorganized infants support the theoretical interpretation that these infants, in contrast to secure infants, lack an appropriate coping strategy.     

When half a word is enough: infants can recognize spoken words using partial phonetic information

Adults process speech incrementally, rapidly identifying spoken words on the basis of initial phonetic information sufficient to distinguish them from alternatives. In this study, infants in the second year also made use of word-initial information to understand fluent speech. The time course of comprehension was examined by tracking infants' eye movements as they looked at pictures in response to familiar spoken words, presented both as whole words in intact form and as partial words in which only the first 300 ms of the word was heard. In Experiment 1, 21-month-old infants (N = 32) recognized partial words as quickly and reliably as they recognized whole words; in Experiment 2, these findings were replicated with 18-month-old infants (N = 32). Combining the data from both experiments, efficiency in spoken word recognition was examined in relation to level of lexical development. Infants with more than 100 words in their productive vocabulary were more accurate in identifying familiar words than were infants with less than 60 words. Grouped by response speed, infants with faster mean reaction times were more accurate in word recognition and also had larger productive vocabularies than infants with slower response latencies. These results show that infants in the second year are capable of incremental speech processing even before entering the vocabulary spurt, and that lexical growth is associated with increased speed and efficiency in understanding spoken language.     

Trauma symptoms among infants exposed to intimate partner violence

OBJECTIVE: To determine whether infants have a traumatic response to intimate partner violence (male violence toward their female partner; IPV) experienced by their mothers, two questions were explored: (1) Is the number of infant trauma symptoms related to the infant's temperament and the mother's mental health? (2) Does severity of violence moderate those relationships? METHODOLOGY: Forty-eight mothers reported whether their 1-year-old infants experienced trauma symptoms as a result of witnessing episodes of IPV during their first year of life. Mothers also reported on their own trauma symptoms that resulted from experiences of IPV. RESULTS: For those infants experiencing severe IPV and whose mothers exhibit trauma symptoms, we were able to predict whether infants exhibited trauma symptoms (b = .53, p < .01). This was not true for children who witnessed less severe IPV (b= -.14, ns). Maternal depressive symptoms and difficult infant temperament did not predict infant trauma symptoms for either group of infants. CONCLUSION: Mothers report that infants as young as 1-year-old can experience trauma symptoms as a result of hearing or witnessing IPV. The significant relationship between infant and maternal trauma symptoms, especially among those infants experiencing severe IPV, are consistent with the theory of relational PTSD. Findings suggest that interventions for mothers and families need to consider the influence of the severity of IPV on very young children.     

Infants' responses to strangers: midget, adult, and child.

Infants respond differentially, and at times with fearlike behavior, to unfamiliar persons. This study was designed to see how infants discriminate among strangers. Since it has been shown that infants respond differently to children and adults, the physical characteristics of persons used to make such differentiations were of interest. Facial configuration and height were systematically varied as 4 different strangers--a male and female child, a female adults, and a small female adult the same height as the children (midget)--each approached 40 different infants. The infants responded as if there were 3 classes of persons--adult, child, and small adult, suggesting that both size and facial configuration cues were used. Infants as young as 7 months of age reacted to the size-facial configuration discrepancy of the small-adult condition.     

Toys and social interaction between infant peers

Claims that young infants fail to react in a social manner to one another and that toys preempt attention to peers were assessed by comparing the interactions observed between infant peers when they met in the presence of toys versus in their absence. 44 pairs of unacquainted infants (either 10--12 or 22--24 months of age) came with their mothers to an unfamiliar room. Without toys available in the room, infants of both ages more often contacted one another, smiled at and gestured to one another, and duplicated each other's actions. With toys, they showed and exchanged toys and spent more time synchronously manipulating similar play material. The results document that infants as young as 10 months of age are responsive to the person and behavior of an unfamiliar peer and that they are no less responsive than older infants to the social versus nonsocial aspects of a novel setting.     

Empowering infants through responsive and intentional play activities

This qualitative case study explored how an infant teacher provided meaningful learning experiences for infants through play and the teacher’s educational rationale behind these experiences. Findings were based on multiple sources of data, including classroom observations (natural observation and videotaped observation) for approximately 12 weeks and a teacher interview. The findings confirmed that infant play is critical for infant learning and development and portrayed the process through which the infant teacher created play spaces for infants and supported infants’ play through both pre-planned, teacher-directed, intentional activities, and child-initiated, emerging play activities. Our study highlighted that the designing of infant play and the learning process needs to be flexible and based on careful observation and reflection in order to meet the rapidly changing needs and interests of a group of infants as well as individual infants.     

Infants of depressed mothers show "depressed" behavior even with nondepressed adults

To determine whether the "depressed" behavior (e.g., less positive affect and lower activity level) of infants noted during interactions with their "depressed" mothers generalizes to their interactions with nondepressed adults, 74 3-6-month-old infants of "depressed" and nondepressed mothers were videotaped in face-to-face interactions with their mothers and with nondepressed female strangers. "Depressed" mothers and their infants received lower ratings on all behaviors than nondepressed mothers and infants. Although the infants of "depressed" versus nondepressed mothers also received lower ratings with the stranger adult, very few differences were noted between those infants' ratings when interacting with their mother versus the stranger, suggesting that their "depressed" style of interacting is not specific to their interactions with depressed mothers but generalizes to their interactions with nondepressed adults as early as 3 months of age.     

Common Themes and Cultural Variations in Japanese and American Mothers' Speech to Infants

This study explored both universal features and cultural variation in maternal speech. Japanese and American mothers' speech to infants at 6, 12, and 19 months was compared in a cross-sectional study of 60 dyads observed playing with toys at home. Mothers' speech in both cultures shared common characteristics, such as linguistic simplification and frequent repetition, and mothers made similar adjustments in their speech to infants of different ages. American mothers labeled objects more frequently and consistently than did Japanese mothers, while Japanese mothers used objects to engage infants in social routines more often than did American mothers. American infants had larger noun vocabularies than did Japanese infants, according to maternal report. The greater emphasis on object nouns in American mothers' speech is only partially attributable to structural differences between Japanese and English. Cultural differences in interactional style and beliefs about child rearing strongly influence the structure and content of speech to infants.

Adults'' Responses to Infants Varying in Appearance of Age and Attractiveness

The relations among age appearance, facial attractiveness, and adult expectations of the developmental maturity of infants were examined in 3 studies. In Study 1, a relation was demonstrated between ratings of the attractiveness (77 judges) and age appearance (53 judges) of 6-month-olds: less attractive infants were judged to be older than their attractive age-mates. In Study 2, 75 parents judged the specific developmental abilities of 6-month-old infants and estimated the age of the babies. Parents overestimated both the age and the developmental abilities of the unattractive infants. Furthermore, ability estimates for the unattractive infants were significantly higher than judgments of the typical abilities of 6-month-olds made by another group of 35 parents. Finally, the results of Study 2 were replicated in Study 3 conducted with 348 mothers. It was also demonstrated in Study 3 that, although mothers expected unattractive infants to be capable of more specific developmental skills, they nevertheless rated the general competence of the unattractive infants to be lower than that of attractive infants. Specious contradictions in the attractiveness and age appearance literatures are resolved by these results: age appearance seems to function as an informational cue with respect to specific age-appropriate abilities, whereas attractiveness elicits evaluative attributions of general competence. Both types of information conveyed in faces may have important implications for adult evaluations of infants and older children.     

Perceptual narrowing of linguistic sign occurs in the 1st year of life

Over their 1st year of life, infants'"universal" perception of the sounds of language narrows to encompass only those contrasts made in their native language (J. F. Werker & R. C. Tees, 1984). This research tested 40 infants in an eyetracking paradigm and showed that this pattern also holds for infants exposed to seen language-American Sign Language (ASL). Four-month-old, English-only, hearing infants discriminated an ASL handshape distinction, while 14-month-old hearing infants did not. Fourteen-month-old ASL-learning infants, however, did discriminate the handshape distinction, suggesting that, as in heard language, exposure to seen language is required for maintenance of visual language discrimination. Perceptual narrowing appears to be a ubiquitous learning mechanism that contributes to language acquisition.     

Infant temperament and subject loss in a habituation procedure

It has been assumed that subject loss in habituation procedures is most likely due to random factors such as the behavioral state of the infant during testing. This study explored the possibility that infant temperament might contribute to subject loss. 114 infants at 3 age levels (11, 18, and 28 weeks) were rated by their mothers on a temperament questionnaire and then subjected to a habituation procedure. Analyses showed that female infants who were unable to complete the habituation task were reported as being more fussy and unadaptable. Female infants were less likely to complete at least part of the procedure than were male infants. The results suggest that subject loss in habituation studies may be the result of nonrandom individual difference factors and not just the result of temporary fluctuations in state.     

Spontaneous Leg Movements of Infants with Down Syndrome and Nondisabled Infants

Infants with Down syndrome (DS) represent a population in which new behaviors are acquired significantly more slowly than in nondisabled infants. We propose that infants' spontaneous movements hold a key to understanding the process of development—of integrating intrinsic dynamics and function. In this investigation, we compared the spontaneous leg movements of 10 infants with DS and 2 groups of nondisabled (ND) infants matched for chronological age and motor age. In contrast to common perceptions, we did not observe a significant difference in the frequency of movements between infants with DS and ND infants. But, infants with DS demonstrated significantly fewer of the most complex patterned leg movements, that is, kicking patterns. Further, the frequency with which both DS and ND infants kicked was significantly correlated with the age at which they began to walk. Biomechanical variables were identified, as well, that related to their emergent movement patterns. These data are consistent with Edelman's proposal that spontaneous movements that occur repeatedly in regions of the organism's functional work space facilitate the development of stable behavioral patterns and emphasize the role of the interaction of multiple subsystems in the emergence of new behaviors.
