Examines the tendency of observers to make less reliable recordings of behavorial events when a calibrating observer is absent. Using four different multicategory systems, 26 experienced observers coded 200 hours of videotaped family interactions. Concludes that observers lapse into a less attentive "set" prior to coding without a…

This study of the stability of parent behaviors toward toddlers over a 3-week period used both aggregated and nonaggregated data. Comparison of stability correlations indicated higher stabilities for aggregated scores, with the level of stability increasing as scores from additional single sessions were aggregated. (PCB)

Habituation to single female faces and to single geometric patterns was observed separately in two groups of infants who participated in two sessions separated by 10 days. Habituation was found to be distributed into three patterns and showed moderate but significant reliability between assessment sessions. (Author/RH)

Describes a new observational study of home television viewing by young children which involved placement of time-lapse video cameras in the homes of five-year-olds from middle-class families for a 10-day period. Families maintained TV viewing diaries, and control groups of families were employed to assess the impact of observational equipment in…

The short-term reliability and long-term stability of visual habituation and dishabituation in infancy were assessed in a sample of 186 infants from four age groups (3-, 4-, 7- and 9-month-olds) seen for two within-age sessions, and in a sample of 69 infants seen longitudinally at 3, 4, 7, and 9 months of age.

Estimates confluence model of intellectual development for a within-family sample of 321 children from 101 transracial adoptive families. Mental ages of children and their parents and birth or adoption intervals were used in a nonlinear least-squares estimation procedure to obtain children's predicted mental ages. Results suggest efficiency of the…

Explains that from a prediction standpoint the confluence model is not very efficient. Very modest increments in accuracy are associated with family configuration variables once chronological age is covaried. Suggests that the major postulates of the theory be tested directly, within individuals and with longitudinal data. (Author/AS)

A neurobehavioral maturity assessment which used data from preterm infants was developed. Eight dimensions of neurobehavioral functioning were found to be stable, nonredundant, and developmentally valid. (PCB)

Results of two studies suggested that acquisition of route mapping during the preschool years provides a means of organizing spatial information and internal representations necessary for successful problem solving in general. (Author/RH)

A 16-item self-report measure of loneliness and social dissatisfaction was developed to survey 506 third- through sixth-grade children. The measure was found to be internally reliable; more than 10 percent of subjects reported feelings of loneliness and social dissatisfaction; and children's feelings of loneliness were significantly related to…

Examines the reliability and validity of the scores of diverse informants from the Child's Report of Parental Behavior Inventory (CRPBI). Also considers the utility of aggregating scores of parental behavior derived from multiple observers. CRPBI items were adapted to obtain mother's, father's, sibling's, and subject's ratings of parental behavior…

While controlling for overall intellectual level, this study assessed the interpersonal problem-solving skills of 150 families via written tests and behavioral performances. Interrelationships between written and behavioral interpersonal cognitive problem-solving skills were examined, as were the relationships of each problem-solving measure to…

Five common play criteria were applied by subjects to a videotape of nursery school children's behavior, rated separately for occurrence of play. The idea that play is best predicted by a combination of criteria was supported by the finding that, when more criteria occurred simultaneously, the more certainly a judgment of play was implied.…

Reviews bases for contemporary discontinuity theories of mental development, presents findings that support alternative proposition of continuity and scrutinizes assessment methods from which these continuity results derive. Also offers several models that help explain the continuity findings, and argues that individual differences in mental…

Describes a new 48-item self-report instrument, the Multidimensional Measure of Children's Perceptions of Control, which defines children's perceptions of control as understanding the locus of sufficient cause for success and failure. Three dimensions of third- through ninth-grade children's perceptions of control are assessed within three…
