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…

In this study of maternal interpretations of infant behaviors, seven mothers of infants with Down syndrome identified 18 of 22 subcategories of potentially meaningful infant behavior previously identified by mothers of typically developing infants. These seven mothers also identified an additional category: developmental status-abilities.…

Reviews the theory and research on the physiological or genetic origins of parenting behavior, noting that an ethological or evolutionary analysis of parenting behavior supports the idea that primates, including man, have evolved psychological structures which are particularly adapted to respond to cues from young children.

Evidence which suggests that pretend activities become increasingly independent of the presence of realistic objects is examined in this paper. Results of research on pretend behavior in children 1 1/2 - 2 years of age are described and analyzed. Striking changes in pretend behavior are shown to occur during the second year of life. Pretend play…

This study investigated at the age at which infants become able to discriminate between their mothers and females strangers, as measured by differential patterns of pauses during the infants' crying while being spoken to by their mothers and female strangers. The subjects, 14 infants ranging in age from 7 to 20 days, were fed, burped, and changed,…

This booklet uses both words and photographs to describe behavior patterns typical of children from one to two years old and to suggest home play activities appropriate for use with children of this age. The booklet is organized into four age ranges: 12-15 months, 15-18 months, 18-21 months, and 21-24 months. Within each of these sections, a…

Seventeen sets of opposite sex twins, 13 to 14 months old, were observed in a playroom situation with their mothers. Attachment behaviors, toy preference, style of play, and activity level were recorded. Analysis of four attachment behaviors indicated that girls looked at, vocalized to, and maintained proximity with their mothers significantly…

Discusses observations of sets of infant twins, aged 6 to 24 months, as they interacted with one another and with an unfamiliar peer. Assesses quality of infant-mother attachment. Finds twins are more likely to react with one another than with a peer. Results are discussed in relation to early peer relationships and attachment. (Author/RWB)

The Mutual Regulatory Model is used to describe the infants' dual task of regulating simultaneously his internal emotional state and his engagement with the external environment. (Author/BB)

Advocates renewed efforts toward assessing attachment on a single continuum of emotional security. Contends that theory is essential to guide attachment assessment and that the constructs of secure base and emotional security provide the needed conceptual foundation. Addresses challenges to the scoring of attachment on a security continuum.…

Observed face-to-face interactions between 39 mothers and their first and second-born two-month olds to evaluate within-family differences in maternal affective behavior toward siblings. Found that mothers were more positive with second-borns than firstborns, and second-borns were more positive than firstborns. Siblings' affective behaviors were…

Studying normal infant development is a challenge for cognitive scientists in general and for neuroscientists in particular because: (1) physiological indices of infant cognition are generally noisy and technically difficult to obtain; and (2) interindividual variability and a paucity of established results make data interpretation very complex,…

This study explores cultural influences in the first three months of life by comparing the daily experiences of first generation Chinese-American and European-American infants whose parents were born in the United States. The study focused on 10 Chinese-American and 10 European-American families whose mothers were recruited during the third…

A study of the effect of the twin sibling relationship upon interactions between monkey mothers and infants. Findings provided strong support for the prediction that the twin sibling presence decreases the amount of behavior directed from infant to mother. Differences in maternal behavior were concluded to be reactions to differences in infant…
