Observational learning of a left-right behavioral asymmetry in mice (Mus musculus).

B6D2F1 hybrid mice that were allowed to observe a trained female mouse open a pendulum door to the right (or to the left) to enter a food compartment later solved this problem faster than pupils that had been placed behind a visual barrier. Male pupils that had observed a "left-handed" teacher performed sinistrally; males that had observed a "right-handed" model performed dextrally. Female pupils did not exhibit their demonstrator's laterality. Observational learning may provide a means to maintain certain lateralized behaviors. Such social learning may lead to the emergence of local traditions and to the cultural diffusion of behavioral asymmetries.

The moderation of adolescent-to-peer similarity in tobacco and alcohol use by school levels of substance use.

Using the National Longitudinal Study of Adolescent Health, this study examined the impact of school-level smoking and drinking on adolescent-peer similarity for smoking and drinking. Hierarchical linear modeling revealed that adolescent-peer similarity was significantly moderated by school-level substance use for both tobacco and alcohol use. For tobacco, similarity between adolescent and peer use increased from .18 in the lower quartile of tobacco-using schools to .44 in the upper quartile of tobacco-using schools. Corresponding similarities for alcohol use ranged from .25 to .34. These results suggest that schools with relatively few substance-using peers provide less opportunities for adolescents to pick niches that expose them to risk factors that correspond to their own substance-use behaviors.
