Two experiments using the habituation-dishabituation paradigm examined infants' ability to form and retrieve a basic-level category. Results indicated that infants categorized when tested immediately and after a five-minute delay. (PCB)

Studied was the development of a variety of grammatical-sensitivity and phonological skills in normally achieving, reading-disabled, arithmetic-disabled, and attention deficit disordered children 7 to 14 years old. (PCB)

Criteria for defining event-frequency encoding as automatic were assessed in two experiments involving young children, college students, elderly, and mentally retarded persons. The first experiment used an online word-frequency task; the second used a study-test method with pictures as stimuli. (PCB)

A cross-age technique was used in two studies to extend understanding of cognitive style development and its cross-cultural generality. Chinese-American children were given the Matching Familiar Figures Test. Results were compared with existing data to determine the style development of children from other cultures. (PCB)

Examines relations between aspects of early child care (age entered, full- or part-time structure and number of child-care arrangements and their quality) and school adjustment. Maternal education was found to be more closely associated with children's school adjustment than maternal employment, marital status, or aspects of child care. (PCB)

Type and quality of nonfamilial child care were found to have no significant effect on peer social skills, sociability with strange adults, and child personality. The major determinants of personality maturity were background variables. Prior social skills and age were the best predictors of peer social skills. (PCB)

This longitudinal study investigated the relation between mood, attitudes, and behaviors in a middle-income sample of first-time mothers. (PCB)

Looked at the quality and quantity of interactions between fathers and their firstborn five-year-olds. Goals were to identify predictors of men's parenting from their own adaptation (direct effects) and from their wives' characteristics (indirect effects). (PCB)

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)

Introduces the Social Relations Model as a new approach for understanding reciprocity during parent-child and sibling play. (PCB)

Investigated the relationship between parents' efforts to initiate and monitor children's peer contacts and the qualities of children's peer relations in nonschool and school settings. (PCB)

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)

Examines the reciprocal relation between parent-child distance and pubertal maturation. Analyses indicate that (1) puberty increases adolescent autonomy and parent-child conflict and diminishes parent-child closeness; and (2) parent-child distance may accelerate pubertal maturation among girls. (PCB)

Relations between hormone levels and aggressive behavior of adolescents in family interactions were examined. Higher estradiol and androstenedione levels were associated with higher degrees of aggressive behaviors in girls. Findings for boys were sparse. (PCB)

This critique of Nisan's (1987) study of morality and convention addresses methodological considerations for cross-cultural research on children's moral and conventional concepts. (PCB)
