Discusses ways in which Myron Hofer's work (1987), which draws on studies of rodents and primates, alters the traditional perspective on human attachment. Emphasizes the importance of the component of attachment that does not develop in explaining attachment in the first six months of life. (PCB)

Examines the development of intermodal perception in infancy by means of a new method, the intermodal learning method. Results support the claim that only subjects who had been familiarized with appropriate and synchronous film and soundtrack pairs showed evidence of intermodal learning. (Author/RWB)

Reveals that different aspects of the environment differentially contributed to variability in communication performance of one-year-old infants. Findings support the environmental specificity hypothesis and underline the need to consider physical environmental parameters when investigating environmental influences. (Author/RH)

Infant temperamental difficulty was strongly related to mothers' level of postpartum depression, both directly and through the mediation of parenting self-efficacy. Social support appeared to function protectively against depression, primarily through self-efficacy. Practical and theoretical implications are discussed. (Author/RH)

Investigates whether 6- to 12-month-old infants' exposure to the successful search behavior of a sibling in two object-concept tasks would enhance infants' subsequent performance on these tasks. (HOD)

It was hypothesized that infants' examining behavior, in contrast to other activity, reflects focused attention and active intake of information. The first study with 7- and 12-month-olds supported the hypothesis. The second and third studies investigated the effects of age and familiarity on both latency to and duration of examining. (Author/RH)

The behaviors of 57 mothers, their preschool-age children, and their infants were observed using a modified "strange situation" to explore the older siblings' potential to act as subsidiary attachment figures. Gamelike tasks were used to assess the conceptual perspective-taking abilities of the older children. (Author/RH)

Data indicate that the interventions provided differed in their effectiveness in calming newborns to a highly significant degree. (Authors)

The Babkin reflex is a reaction to the simultaneous pressing of the palms of the hands of the infant. (Authors)

Premature infants vocalized less, played less, and were more fretful than full-term infants of the same chronological age, although they looked at objects and looked around their environment more. Mothers of premature infants demonstrated more caretaking and affectionate behavior toward their infants. Between-group differences decreased as age…

Develops a methodology for studying emotion socialization and examines the synchrony of mother and infant expressions to determine whether "instruction" in display rules is underway in early infancy and what the short-term effects of such instruction on infant expression might be. Sixty dyads were videotaped during play and reunion after brief…

Investigated the effect of increasing familiarization time on the visual recognition memory of 6- and 12-month-old full-term and preterm infants. Results suggested that persistent differences exist between preterm and full-term infants throughout at least the first year of life in this fundamental aspect of cognition. (Author/RH)

Preferential looking at stimuli varying in temporal frequency was examined in 11 prematurely born infants. The relationship between amount of looking and stimulus frequency yielded a significant linear trend with the fastest frequency used (4 hertz) being most preferred. (Author/DB)
