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…

Longitudinal research has shown that communication deficits (negative interaction) precede the development of relationship distress. To investigate the antecedents of relationship stability and adjustment 31 couples who were seriously considering marriage participated in a longitudinal study. The couples initially completed the Marital Inventories…

This study investigated several questions concerning the amount of viewing and types of programs children and parents watch alone and together. Patterns of children's viewing with and without parents were examined, as well as how parent-child coviewing affects individual family members' viewing. Children 3 to 5 and 5 to 7 years old, and their…

Social competence of 239 students with and without learning disabilities (LD) was followed from kindergarten through fifth grade. Students with LD demonstrated the same trends in social competence as non-LD students. Students with LD differed significantly from average-high-achieving non-LD students on social skills and behavior problems, but not…

Using a longitudinal design, investigates the interactive behaviors of mothers of normal infants and mothers of infants who are known to differ on a host of cognitive, behavioral, and biological parameters. Examines the developmental course of emotional expressivity in these infants. (HOD)

Combines and examines evidence from two longitudinal studies of infant and family development to determine whether experience of extensive nonmaternal care in the first year is associated with heightened risk of insecure infant-mother attachment and, in the case of sons, infant-father attachment. (Author/RWB)

Even though attrition presents a serious threat to the validity of longitudinal research, there is a lack of standardization for reporting it. To examine the effectiveness of four tests for attrition -- two for external validity and two for internal validity -- the tests were applied to two large scale projects: the first, Project HASP, is a…

Research in the area of social cognition has suggesed that actual stimuli don't predict later judgments and responses as well as cognitive representations of and cognitive responses to those stimuli, in the form of attitudes, impressions, or causal attributions. To identify the factors most important in predicting adolescent smoking, a 4-year…

The Carolina Longitudinal Learning Disabilities Project identified 42 first- and second-grade students with learning disabilities (LD) and compared their development over 5 years with that of randomly selected peers. Different variables were predictive for the two groups. Teacher perceptions of intelligence, measured intelligence quotient, grade…
