Little is known about how children's value priorities develop over time. This study identifies children's value priority profiles and follows their development during middle childhood. Australian children (N = 609; ages 5-12 at Time 1) reported their values over 2 years. Latent Transition Analysis indicated four profiles: Social-Focus, Self-Focus,…

Speech productions of 40 English- and 40 Japanese-speaking children (aged 2-5) were examined and compared with the speech produced by 20 adult speakers (10 speakers per language). Participants were recorded while repeating words that began with "s" and "sh" sounds. Clear language-specific patterns in adults' speech were found,…

Evaluated the relation between fetal activity and postnatal behavior and development by measuring the amount of fetal movement occurring in response to stimulation and the number of stimulus applications necessary for habituation. Preliminary evidence suggests that fetal rate of habituation predicts some aspects of infant behavior and development…

Examined Bowlby's proposition that early experiences and the adaptations to which they give rise influence later development, even beyond the influence of current circumstances or very recent adaptation. Groups whose adaptation were similar during preschool years but consistently different earlier were defined and compared. Results supported…

Studied perceptions of self-competence and task values, documenting domain-specific growth trajectories for 761 children from grade 1 through 12. Found that self- perceptions of competence and subjective task values declined as children got older, although extent and rate of decline varied across domains. Found significant gender differences in…

Predicted children's loneliness and social satisfaction growth curves based on changes in peer victimization status from kindergarten through third grade. Found that trajectories for children moving from nonvictim to victim classification showed increasing loneliness and decreasing social satisfaction. However, moving from victim to nonvictim…

Used heart rate and respiratory sinus arrhythmia (RSA) assessed at 33 to 35 weeks gestational age to predict developmental outcome at 3 years for very low birth weight infants. Found that RSA measures predicted developmental outcome beyond effects of birth weight, medical risk, and socioeconomic status. For infants < 1,000 grams, RSA maturation…

Presented are a literature review and new data on correlates of newborn auditory brainstem evoked responses (ABRs). Concludes that disorders of the central components of the ABR may be more of prenatal than of postnatal origin. The I-V interval had low but reliable correlations with four of 11 Brazelton scale variables. (RH)

Investigated the extent to which family environment predicted differences in trajectories of adaptive development in young children with Down syndrome. Found that growth in communication, daily living skills, and socialization domains were predicted by family cohesion and mother/child interaction beyond that predicted by maternal education. Bailey…

Identified groups of economically disadvantaged children showing high externalizing behavior in first grade that persisted (persistent) or decreased (improver) in third grade, or low first- grade levels that were stable (unproblematic) or increased (new problem) in third grade. Found that verbal ability, behavioral impulsivity, parent…

Used new administration procedure of Self Description Questionnaire to assess dimensions of young children's self-concept in a multicohort-multioccasion study. Found that the scale's reliability and stability improved with age and from one year to the next. Gender differences were stable over age. Time 1 teacher ratings contributed to the…

The results, which contrasted markedly with findings of major group differences at 12 months of age, indicated that by age two no group differences were apparent on any child development, mother-child interaction, or maternal attitude measures, except that preterms were significantly poorer in motor skills than were full-term infants.
