Suggests that the findings in the study by Blass and Ciaramitaro reported in this monograph support the claim that two systems of infants' behavior state regulation accessible by oral stimulation are mediated by different neural pathways. Discusses the findings in light of the immediate aims of the study itself and for the broader context of…

Infants participated in a nonsocial contingency task immediately after a social interaction with their mothers. The amount of time mothers and infants spent in a state of vocal turn-taking predicted individual differences in infants' subsequent performance on the contingency task. (PCB)

Measures of positive and negative affect and affect ability; of look, approach, and proximity behavior; and of overall response pattern were obtained from 66 infants of 12 months. These measures and other results suggested that both parents are significant sources of emotional guidance for infants in conditions of uncertainty. (RH)

Examined role of mother-toddler attachment in moderating the relationships between behavioral inhibition and changes in salivary cortisol levels in response to novel events. Subjects were 77 infants 18 months old. Found elevations in cortisol only for inhibited toddlers in insecure attachment relationships. Mothers in these relationships appeared…

This study compared the reinforcement effects of imitation to the elicitation effects of noncontingent maternal vocal stimulation. Subjects were 17 three- to six-month-old infants and their mothers. Infants received three successive experimental conditions: contingent imitation B1, noncontingent elicitations, and contingent imitation B2. Under the…

The purpose of this study was to investigate the alternative forms of young children's help-seeking in free play and problem-solving contexts. A total of 72 children aged 18 (N=36) and 24 (N=36) months were observed in pairs in free play and problem-solving settings, as well as in different social contexts--same-age versus mixed-age pairing. Both…

Study supported in part by Research Grant MH-13703-01 from the National Institute of Mental Health.

Sixteen white home-reared babies (eight boys - eight girls) ranging in age from six months to two years were studied during home visits. Piaget's sensory-motor development theory of imitation was employed, and his special thesis of the hierarchical sequence was tested. The examiner proposed four critieria for assessing the development of imitation…

Results from this study of 110 low-risk, middle-class infants showed that a significantly greater proportion of infants whose mothers worked full-time outside the home were assigned to the category "insecure-avoidant" than infants whose mothers remained in the home throughout their children's first year of life.

Quantifies behavioral periodicities or cycles during face-to-face interaction between three- and five-month-old term and preterm infants and their mothers. Compares the temporal organization of social interaction between term and preterm infants. Spectral and cross-spectral techniques showed the existence of periodicities. Differences were found…

Analyzes conversations between one mother and her 22-month-old child, describing sequences the pair used in clarifying each other's focus of attention and in instructing and learning about concepts and motor skills. Results highlight the importance of the intensive learning environment provided by home conversations. (RH)

Training was found to increase both parents' and infants' competence in the parent-infant dyad. A reciprocal relationship between increases in the trained fathers' interactions and decreases in the trained mothers' interactions was found, indicating that the triad may be the crucial unit for studies of parental competence.

Evaluates the effects of continuous lumbar epidural anesthesia on the newborn and on the developing mother- infant relationship. (Author/MP)

This study examined the associations between characteristics of mothers' narratives about their 7-month-olds, maternal depression, and their infants' affect regulation during the Still Face procedure. Findings showed that mothers' representations were linked with individual differences in infants' behavior, the association between mothers'…

The interactive behaviors of eight deaf and eight hearing mothers and their hearing infants were examined during play. Compared to hearing mothers, deaf mothers produced fewer, shorter vocalizations, but more nonvocal initiations. The two groups of infants differed on frequency and duration of their vocalizations only at the 16-17 month age level.…
