Investigated (1) the relationship between the quality of attachment and the development of symbolic play, and (2) differences in the ways mothers of secure and anxious children involved themselves in play. Frequency, duration, and complexity of children's play, along with differences in maternal involvement, were assessed across bimonthly free…

Compares attachment relationships of infants at 12 months to their visual self-recognition at both 18 and 24 months. Individual differences in early attachment relations were related to later self-recognition. In particular, insecurely attached infants showed a trend toward earlier self-recognition than did securely attached infants. (Author/NH)

Examined relations among adrenocortical stress reactivity, infant emotional or proneness-to-distress temperament, and quality of attachment in 66 infants tested at 9 and 13 months. Adrenocortical activity was not associated with attachment classifications. Significant only at 9 months, elevations in cortisol were small. (RH)

A total of 43 mothers of 13-month-old infants were asked to position individuals who were close to them in a network diagram and to indicate which of those individuals provided support. Mothers reported extended networks. Results affirm the importance of spousal support for mothers of infants in intact families. (Author/RH)

The facial expressions of twenty-eight 13-month-old middle-class children were videotaped during the 3-minute separation episode of the Ainsworth strange-situation procedure. Anger was the dominant negative emotion expressed by the majority of children; patterns of emotion expression varied with type of attachment; and the proportion of time anger…

Two studies were conducted to (1) develop measure of infants' executive capacity, defined as difference between infants' most sophisticated level of functioning displayed first in free and then in elicited play and (2) to test several hypotheses regarding relationship between these performance and competence measures of child functioning and home…

Tested the hypothesis that development of secure attachments is predictable from synchronous, and insecure attachments from asynchronous interactions across the first year. Findings from 30 dyads (10 secure, 10 avoidant, 10 resistant) supported the hypothesis at one and three months, with synchronous interaction observed at significantly,…

Previously published data on infants aged 12 and 13 months who were observed in the Strange Situation with their mothers and fathers were reanalyzed using a component process approach. (PCB)

Reports relationship between asymmetries in frontal-brain electrical activity and individual differences in affective response in 35 ten-month-old females. Stranger-approach, mother-approach, and maternal-separation experiences were presented while an electroencephalogram (EEG) from scalp regions was recorded and facial and other behavioral…

Effects of maltreatment were examined in three domains suggested by attachment theory: relationships with novel adults, effectance motivation, and cognitive maturity. Three samples of four- to eight-year-old children were studied: 93 maltreated children, 67 demographically matched nonmaltreated childen, and 30 nonmaltreated middle-class children.

Examines associations among contemporaneous measures of marital quality, parenting attitudes and behavior, and toddler development in two-parent families. Seventy-five families with one 20-month-old child served as subjects. Results generally indicated that good marital quality was associated with optimal toddler functioning and sensitive…

Distress in response to brief maternal separations was examined in a sample of 93 predominantly home-reared infants using the Ainsworth strange situation paradigm. At 18 months, the age when separation protests begin to decline, securely attached infants are better able than anxiously attached infants to tolerate maternal separations. (Author/RH)

Tested two models of the relationship between a hypothetical attachment mechanism and an incompatible motivation (a tendency to explore) by pitting two levels of attachment motivation against two levels of exploratory motivation among 15- to 18-month-old infants, alternating freely between play with novel toys at one end of the room and visits…

Fifty-six 12-month-old infants, (10 maltreated infants; 18 nonmaltreated, high-risk infants; and 28 matched low-income controls) were videotaped at home with their mothers for 40 minutes and were observed two weeks later in the Ainsworth Strange Situation. Maltreating mothers could be discriminated by uninformed coders from nonmaltreating mothers.…

Investigates the impact of early maternal employment--direct (mother-child) and indirect (father-child) effects--in families with firstborn 20-month-olds. Shows maternal employment is not related to toddler outcomes (security of attachment or problem-solving behavior). (HOD)
