This paper presents tables for converting raw scores on the Bayley Scales of Infant Development to Mental Development Index and Psychomotor Development Index values. The tables were developed to generate index values for young children with developmental delays, based on recent revision of the scales and standardization procedures. Methodology is…

Examined the attachment status of infants in the home and laboratory by observing infant temperament and maternal parenting sensitivity, as well as parent reports of infant temperament. Subjects were 49 families and their infants. Results highlighted the need to consider other factors besides maternal sensitivity to explain the variability in the…

A review of studies on identity status and of a study involving 2,557 Dutch adolescents who completed the Utrecht-Groningen Identity Development Scale (W. Meeus, 1993) supports a refinement of the identity status model that shows progressive developmental trends and indicates that the difference between high and low statuses increases with age.…

Possible antecedents of toddler gender separation were studied with 57 toddlers with a mean age of 35 months. There were no differences between gender-segregating and nonsegregating children regarding gender toy preferences or gender awareness, but teachers saw gender-segregating girls as more socially sensitive.

Whether mental attentional capacity increases as a linear function of age during normal childhood development, as predicted by the neo-Piagetian developmental theory of J. Pascual-Leone (1970 and later), was studied with 215 children aged 5 to 12 years. Results provide only partial support for the Pascual-Leone theory. (SLD)

Describes the integration of research-based practices into youth problem behavior prevention, examining the developing integration of science and prevention practice regarding: increasing use of epidemiological evidence about youth problem behaviors to guide prevention; a system for monitoring the incidence, prevalence, and context of youth…

Describes the occurrence of childhood Unwanted Sexual Attention (UWSA) and explores its relation to child sexual abuse (CSA). Findings suggest that UWSA is an almost universal experience for girls that causes significant anger and fear. Assessing UWSA will be important from a public health perspective in evaluating if such behaviors pose a risk…

Used a matched-schools design, school-level achievement, and disciplinary data to evaluate the effectiveness of the elementary-level Positive Action program on students' performance and behavior over time. Results indicated that program participation improved student behavior, school involvement, and academic achievement into high school. The…

Examined the effect of attention on infants' responses to briefly exposed visual stimuli. Found that the duration of stimulus exposure in the familiarization phase was positively correlated with the preference for the novel stimulus in the paired-comparison procedure, and processing of briefly presented visual stimuli differed depending on the…

Explored whether a system between written place-value system and base-10 manipulatives helped children understand place-value. Found evidence that the intermediate system helped children differentiate between face values and complete values of digits in multidigit place-value number representations, and to grasp that the sum of the digits'…

Investigated intra-individual development of ability to modify the size of a human figure drawing. Found through longitudinal data that children between ages 7 and 9 were able to reduce drawing size. Discovered that the larger the figure initially, the more complex the level of spatial axes system, and the more persons in the picture, the greater…

Studies show that children who have trouble making and keeping friends during their early years often develop negative attitudes toward school. Friends provide important functions in child development, which include supplying emotional and cognitive resources. Friends also help one another develop social skills. (MLF)

Describes the impact of violence on young children. Discusses the prevalence of children's exposure to violence, research on violence and young children, the impact of media violence on children, and characteristics of children who live with violence and those who witness violence. Recommends comprehensive, multidimensional strategies to address…

This study used a pluralistic model to examine the procedures used by two preschoolers to achieve written productions using invented orthographies. The model allows children's procedural variations to be taken into consideration by understanding the hierarchy of different processing modes available to children in completing the task and…

Discusses social, economic, and political conditions that influence the growth and health of children of Guatemalan Maya immigrants to the United States. As of 2000, Maya-American children age 6-12 years were, on average, 11 centimeters taller, and also heavier, than their Guatemalan peers. The heaviness is probably due to sedentary lifestyles.…
