Examines the conceptual and empirical foundations of individual drug use stage development and progression related to tobacco, alcohol, and other drugs. Research examining interdrug use progression among youths supports the idea of a generally invariant sequence, involving nonuse to legal drug use, marijuana, and finally other illegal drug use.…

Examination of 53 children with autism supported the validity of the subtypes "aloof" and "active-but-odd" as predictors of behavior across language/communication, reciprocal social interaction, and stereotyped behavior/restricted interest domains. Partial support for an intermediate, "passive" subtype was garnered. (Author/JDD)

Studied whether behavioral styles at age 3 are linked to personality traits at age 18 after identifying 5 temperament groups (undercontrolled, inhibited, confident, reserved, and well-adjusted). Results pointed to continuities across time. (DR)

Study of same-sex play networks found that between ages four and six, the size of girls' play networks decreases along with the number of girls excluded. Although results did not confirm the hypothesis that the size of boys' play networks increases, there was a trend for boys in the older classes to exclude fewer playmates from their networks. (AA)

The relation of prosocial behavior of 53 preschoolers to different modes of vicarious emotional responses was examined. Videotapes were used to elicit empathy, whereas vicarious emotional responses and defensive behaviors were assessed by means of self-report, facial, and heart-rate indexes. (SH)

In contrast to earlier notions, a systems view of an organism's development sees genes as only one component in a hierarchy of influences that produces finished traits and differentiation. Developmental canalization proceeds from genes, behavior, and environment as well as from the coaction of these factors. (BC)

Notes that psychologists' interest in behavioral development concerns individual differences in behavior. Explores complexities of genetic and environmental determination of development, and of canalization. Intelligence is considered as an example of the canalization of human behavior. (BC)

Maintains that (1) research questions must address intra- and extraorganism contextual relations and must be multidisciplinary in scope; (2) research must be sensitive to contextual variability and individual differences; and (3) scholars must develop empirically generative models linking the development of human beings with changing contexts. (BC)

This paper on the problem of sex offending among individuals with intellectual disabilities examines the incidence of this problem, characteristics of intellectually disabled sex offenders, determination of whether the behavior is a paraphilia or functional age-related behavior, and treatment options, with emphasis on the situation in New South…

The Battelle Developmental Inventory (BDI) was administered to 121 young children, and parents rated them with the Social Skills Rating System 2-3 years after entry into the study. Correlations between the two measures revealed very weak to modest relationships, providing limited support for the BDI as a predictive measure of future…

Examined early adolescents' self-esteem and perceived competence in the cognitive, social, and physical domains. Self-esteem, perceived social and physical competence, and cognitive competence were either stable or increased for most children. Concluded that early adolescents' perceptions of self-esteem and competence are not adversely affected by…

Describes a teacher's experiences with a kindergarten class of developmentally delayed children. Offers strategies for changing behavior, stimulating cognition, influencing self-esteem, and teaching early academics. Two students' stories demonstrate progression from uncontrollable behavior to attention and eagerness to learn. (SH)

Described is an ongoing study of monozygotic and dizygotic twins, separated in infancy and reared apart. Discussed are the procedures and results of this study with interpretations of the results. The effects of parenting, education, and other interventions are considered. (CW)

A portrait is presented of the toddler with slow expressive language development (SELD), based on research examining the health history; cognitive, communicative, and adaptive skills; behavior; and phonology of 30 toddlers with SELD and 30 nondisabled toddlers. The paper offers a review of research on the outcomes of SELD, and explores…
