Examines research which indicates that in the first days of life infants are able to elicit and respond to their mothers' behavior, however, it appears that the newborns exert more influence over the mothers' actions than the mothers exert over the infants' actions. (MH)

Examined cardiac response and ratings of subjective aversiveness to recordings of unfamiliar infant cries in 60 primiparous women at 32 weeks' gestation. Mothers who prenatally rated the crying recordings as more aversive postnatally described their infants as more fussy and unpredictable. Women who showed greater cardiac acceleration to the cries…

Examined predictive validity of measures of infant habituation and later aspects of temperament. Found babies who habituated sooner (fewer trials to criterion) at five months of age and had fewer peak fixations during habituation were rated by mothers as more active, intense, and negative in mood, and less persistent and adaptable. Age differences…

Contends that cultural practices such as carrying the baby on the mother's back for prolonged periods can impact negatively on development of visual integration during the sensorimotor stage pathways by preventing adequate or enough crawling. Maintains that crawling is essential for cross- modality integration and that higher mental functions may…

Examined in four studies whether and when infants connect information about an actor's affect and perception to their action. Found that 12-month-olds, but not 8-month-olds, recognized that an actor was likely to grasp the object she had visually regarded with positive affect. Replicated findings with 12- and 14-month-olds and with several…

Explores the possibility of sex and socioeducational differences in young infants' patterns of vocal interaction with mothers and strangers at two and three months of age. Infants at both ages vocalized more to mothers than to strangers. (BB)

Argues that this volume's Sanson, Prior, and Kyrios study on the overlap between measures of temperament and psychopathy is too narrowly framed. Maintains that there appears to be a pattern of linkage between specific early temperament scales and specific kinds of later behavior problems. (Author/BB)

Compares differences between adolescent and older mothers on tests of infant motor, cognitive, social and language development; and first- and second-year abilities. Older mothers were better at predicting emergence of infant behaviors and first-year behaviors. There was no difference between groups in predicting second-year behaviors. (Author/BB)

Discusses some of the problems that infants and toddlers experience in infant and toddler day care programs, and suggests four program features that are vital in aiding infants and toddlers in the early years of care. (BB)

Findings of a study of 32 infants attending a neonatal intensive care unit follow-up clinic included mechanically ventilated infants were more irritable than nonventilated infants; infants from lower income families were fussier than infants from higher income families; 5-minute Apgar scores were more predictive of infants' success on a visual…

Describes the core constructs of attachment theory, namely, the attachment system and secure-base behavior. Discusses contextual factors thought to be crucial in development of individual differences in attachment, especially maternal sensitivity, and considers child characteristics, especially temperament, that may contribute to the attachment…

Six children were visited in their homes every 2 weeks for 18 months from the age of 6 months to observe their developing comprehension and production of words. Results showed both similarities and individual differences in patterns of early comprehension. A close relationship was noted between early production and comprehension of words;…

Examined the possibility that auditory stimuli with properties of adult-to-infant speech are more detectable in a noisy ambient environment than ones that resemble adult-to-adult speech. Findings suggests that properties that characterize adult-to-infant speech may compensate for young infants' low-frequency deficits and therefore facilitate the…

Rejects the neuronal fatigue, or selective adaptation, hypothesis of young infant habituation. Holds that studies cited by Dannemiller and Banks do not support the inferences of selective adaptation. Rejects the hypothetical neurophysiological mechanism of neuronal fatigue. Proposes that studies do not indicate that young infants' visual cortical…

Examined the possibility that relations in the family system are affected when infants begin to crawl. Parents' expressions of prohibition and anger, and their use of physical punishment, increased after infants began to crawl. (BG)
