Is an attenuated physiological response to family conflict, seen in some youth exposed to early adversity, protective or problematic? A longitudinal study including 54 youth (average age 15.2 years) found that those with higher cumulative family aggression exposure showed lower cortisol output during a laboratory-based conflict discussion with…

Using strict and lenient mathematics achievement cutoff scores to define a learning disability, respective groups of children who are math disabled (MLD, n = 15) and low achieving (LA, n = 44) were identified. These groups and a group of typically achieving (TA, n = 46) children were administered a battery of mathematical cognition, working…

Results of this replication study indicate considerable agreement with Piaget and Inhelder's description of stage-related verbal features while failing to confirm their description of stage-related nonverbal features. (JMB)

A total of 61 children from first through sixth grades participated in four balance-scale and four inclined-plane problem types in a study testing for invariance of subject classifications as rule-users across problems whose products differed but whose type did not. Results indicated that many children's classifications differed across…

Reexamines data from a study by Bayley and Schaefer and argues that no significant sex difference was demonstrated in their study. Points out that the male and female samples differed significantly with respect to both level of mother's education and children's IQ variance. (Author/JMB)

Five experiments tested whether children understand pretense intentions before they understand pretense mental representations. Findings revealed that children did not understand that intention is crucial to pretense. Various methodological factors that might have compromised results such as force choice versus yes-no questions or using a…

Maintains that Lillard's and Joseph's articles provide an example of how apparently divergent empirical results may turn out to reflect interesting differences between children and adults. The researchers agreed that for young children, pretense is often, but not necessarily, intentional and neither found evidence for a representational…

A transcript-narrative analysis technique was used to identify interpersonal negotiation strategies of two nine-year-old boys selected from a pool of children with socioemotional and interpersonal difficulties. Strategies were classified according to four developmental levels: impulsive/physical, unilateral/coercive, reciprocal/influential, and…

An analysis using data drawn from Nancy Bayley's Berkeley Growth Study is performed for didactic purposes to illustrate the use of structural equation modeling on a child development data set. Alternatives to standard latent factor approaches are demonstrated for use in research situations in which the subject-to-variable ratio is less than…

Provides an introduction to loglinear analysis of cross-classification tables, including tables with nominal and ordinal variables. Compares the chi-square test of independence with the loglinear model of independence. Reviews the advantages and overall strategy of loglinear modeling. Each model discussed is applied to data from the developmental…

Reports three experiments which investigated the ability of children aged four to nine years to organize body-location information in recall. Attempted to correct for methodological confounding in previous similar research. (JMB)

Examined implicit learning in 432 four- to 10-year-olds in 3 experiments, using a new paradigm based on drawing behavior. Found that children modified drawing behavior following specially devised practice in such a way that the changes could not be viewed as resulting from deliberate adaptive strategies, with modifications lasting for at least 1…

Examines language effects in class-inclusion performance with 224 children ages 3 through 12 by comparing the standard Piagetian question with two alternate question forms. Overall, the findings were inconsistent with the Piagetian assertion that logical inability produces errors in comparing subclasses; inclusion performance was a function of…

Maintains that recent theoretical and methodological advances have sparked renewed interest in studying children's learning. Describes consistent and interesting findings regarding how children learn and intriguing proposals regarding mechanisms underlying learning. Argues that increasing the focus on children's learning promises practical…

Examines 16 major community surveys designed to measure prevalence of childhood emotional and behavioral conditions, discussing definitions of deviance, instruments, and methodologies used, as well as potential correlates of disorders studied. Suggests directions for research. (Author/MP)
