The ability of three-year-old children to deceive was examined in order to determine whether they were able to hide their emotional expression intentionally. Results indicated that very young children have begun the process of learning how to mask their emotional expressions and support the role of socialization in this process. (RH)

The selection of acts from the stream of infant behavior is examined. Adults (140 mothers, fathers, and other men and women) viewed videotapes of 9-, 15-, and 21-month-old infants. One half noted meaningful acts; the other half noted intentionally communicative acts. Parents selected more meaningful acts than nonparents and agreed more about…

Examines the relations of Type A scores of parents to Type A scores of their children. Parent-child correlations were found for father-son pairs. (PCB)

Evaluates the efficacy of a multisystemic approach to treatment of juvenile offenders and their families. One group of delinquent adolescents received family-ecological treatment, another group of delinquent adolescents received an alternative treatment, and normal adolescents served as developmental controls. Findings support a multisystemic…

Tests three previously untested hypotheses central to the theory of Brazelton and colleagues about the sequential structure of mother-infant face-to-face interaction. Results show that with some revision the hypotheses describe the structure of mother-infant face-to-face interaction from three to nine months of age. (Author/RH)

Temperament is examined from a longitudinal, within-individual perspective in order to investigate short-term change and patterns of temperament changes. For 100 consectutive days five mothers completed a temperament survey, reporting on their own and their two-year-old children's behavior. Patterns of change were identified for both mothers and…

Ability of 26 newborns to imitate facial expressions was examined. When infants observed emotional facial expressions, they did not show imitative matching of the modeled expressions. However, when tongue protrusion was modeled, infants did produce the modeled gesture. (PCB)

This study used data from the Berkeley Guidance Study (1954) to identify children with a pattern of temper tantrums in late childhood (ages 8-10) and to trace the continuities and consequences of this behavioral style across the subsequent 30 years of their lives. Life course continuities in behavioral style were found for both sexes. (Author/BN)

Examines the childrearing correlates of impulse control in 18 mothers and their 14-month-old toddlers. Shows that mothers who relied on physical punishment had infants who were more likely to ignore maternal prohibitions, to manipulate breakable objects, and to show low levels of nonverbal competence seven months later. (HOD)

Tests the ability of 43 children, ranging in age from 20 months to 40 months, to discriminate between pictures of boys and girls and male and female adults. Compares children who passed this gender-task with those who failed it on three behaviors most often categorized as sex-typed: toy choice, aggression, and peer playmate selection. (HOD)

Explores the differences between boys and girls (5- and 7-year-olds) in their use of two kinds of strategies with interpersonal conflict: (1) active persuasion and negotiation, and (2) mitigation without disrupting social harmony between the interactors. (HOD)

Examines the social behavior of 34 preschool children, observed both at home and in preschool, to determine patterning interactions among siblings and consistency in children's interactions with siblings and peers. Concludes that children's behavior at home is most affected by relative age of their siblings. (HOD)

Observed play of 52 toddlers with a set of socially stereotyped masculine, feminine, and neutral toys in a day care setting over 14 months to (1) determine the age at which toddlers consistently exhibit sex-stereotyped toy choices in a natural setting and (2) investigate relation of parents' expectations and the children's own knowledge of gender…

Examines adolescents' susceptibility to peer pressure in after-school experiences in a large sample of fifth, sixth, eighth, and ninth graders. Shows that adolescents who report home after school are not significantly different from those who are supervised by their parents at home during after-school hours. (HOD)

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…
