Given the value placed on honesty and the negative consequences of lying, encouraging children's truth-telling is important. The present investigation assessed honesty promotion techniques for encouraging 3-8-year-old Canadian children's (Study 1: n = 301, 54% female; Study 2: n = 229, 50% female from predominantly White middle-class samples)…

To successfully navigate an uncertain world, one has to learn the relationship between cues (e.g., wind speed, atmospheric pressure) and outcomes (e.g., rain). When learning, it is possible to actively manipulate the cue values to test hypotheses about this relationship directly. Across two studies, we investigated how 5- to 7-year-olds actively…

Anger is a central characteristic of negative affect and is relatively stable from infancy onward. Absolute levels of anger typically peak in early childhood and diminish as children become socialized and better able to regulate emotions. From infancy to school age, however, there are also individual differences in rank-order levels of anger. For…

Despite the well-established protective functions of guilt across childhood, its underlying physiological mechanisms have received little attention. We used latent difference scores (LDS) to model changes in children's (N = 267; 4- and 8-year-olds, 51% girls) skin conductance (SC) and respiratory sinus arrhythmia (RSA) while they imagined…

Although abundant research has demonstrated associations between psychologically controlling parenting and adolescent problem behavior, little is known about the moderating role of adolescent personality herein. This study examined whether adolescent personality moderates the associations between parental psychological control and internalizing…

Illustrates contribution of genetic and environmental factors to differential ratings of within-family behavior and environmental differences. Maintains that, assuming differential ratings are a linear function of underlying trait differences, it is simple to recover within-family statistics, offering a more legitimate basis than comparing mean…

Studied the adjustment status associated with engagement in gender normative versus gender nonnormative aggression for boys and girls. Teacher and self-reports were used to assess internalizing and externalizing difficulties. Found that 9- to 12-year olds who engaged in gender nonnormative aggression were more maladjusted than children who engaged…

Reviews research examining the predictive aspects of childhood sex-typed behavior for sexual orientation. Prospective studies suggest that childhood cross-typed behavior is strongly predictive of adult homosexual orientation for men, whereas retrospective studies are useful in determining how many homosexual individuals displayed cross-sex…

Examined predictive relations between infant assessments and behavior problems at age 7 in a low-income sample. Found that disorganized infant attachment behavior and below average mental development at 18 months were associated with externalizing behavior at 7 years. Avoidant infant attachment behavior was associated with later internalizing…

Two studies examined children's and adolescents' attitudes toward aggression. Found that boys viewed physical aggression as more hurtful than social aggression and girls rated social aggression as more hurtful. Girls rated an aggressor as more angry than did boys. Middle and high school participants viewed social aggression as indicating more…

Replicated and extended American research on overt and relational aggression with Italian children. Found that peer and teacher nominations for aggression and prosocial behavior were highly stable, although with very poor concordance between them. Peer nominations for overt and relational aggression were linked to peer rejection. Boys' scores were…

Related maternal depressive symptoms obtained when infants were 1, 6, 15, 24, and 36 months old to child functioning at 36 months. Found that women with chronic symptoms were least sensitive during mother/child play from infancy through 36 months. Maternal sensitivity accounted for group differences in school readiness and verbal comprehension and…

Developed measures of relational aggression for young children. Found that relational aggression appears at young ages and can be distinguished from overt aggression.
