Adolescent marijuana use: the role of the physician

Adolescent marijuana use is an issue of concern to the community at large. Physicians now have the technology to identify marijuana use and thus are in a unique position to deal with the issue. This article addresses the moral issues related to screening and surveillance of adolescent marijuana use and postulates the justification for active physician intervention.     

Violent crime, sociopathy and love deprivation among adolescent delinquents

Ever since Wechsler observed that the adolescent sociopath characteristically scored higher on the performance section of the Wechsler IQ scale relative to the verbal section, psychologists have been debating its meaning. This study examines the relationships between P-V discrepancy scores, love deprivation, and juvenile delinquency among a sample of juvenile probationers. P greater than V scores were significantly related to love deprivation and violent crimes. It was determined that much of the explanatory power of P greater than V with regard to violent delinquent behavior was mediated by love deprivation. We also found that P greater than V scores could not be explained away by social class, low verbal scores, or lower full-scale scores. Only love deprivation was found to be significantly related to P greater than V scores in our path model, thus offering some support to the assertions of some authors that early emotional stresses affect subsequent autonomic nervous system function.     

How adolescents perceive their relationships

In order to determine how adolescents perceive their relationships, a set of eight drawings representing one, two or three characters, whose sex and relationships where not clearly defined, were shown to 403 Parisian adolescents (227 girls and 176 boys) aged 15 to 19. The majority of data converge for all subjects, regardless of the sex, curriculum or socioeconomic factors. The subjects consistently identify more mixed-sex dyads and triads than same-sex in all pictures. This predominance does not imply that the adolescents perceived all relationships as having a romantic connotation. Some data seem consistent with the traditional sex role stereotypes. The subjects' responses do not seem to reflect the reality of their own peer relationships.     

A DAY AT DEVELOPMENTAL DOWNS: SPORTSCAST FOR RACE #2 - NEO-PIAGETIAN THEORIES OF COGNITIVE DEVELOPMENT

This article discusses the neo-Piagetian theories of cognitive development proposed by Robbie Case, Andreas Demetriou and Anastasia Efklides, Kurt Fischer, Jeffrey Farrar, Graeme Halford, Juan Pascual-Leone, Michael Shayer, and Robert Siegler. Each theory is discussed in terms of its basic assumptions, and propositions regarding structure, process, novelty and automatization, context, and mechanisms of development. Then some general conclusions are drawn about the enterprise of neo-Piagetian theorizing as a whole.
