RT Book T1 Developmental trajectories of nonsocial reinforcement and delinquency in adolescence: An exploratory study of an understudied part of social learning theory A1 Marcum, Cathy LA English YR 2011 UL https://krimdok.uni-tuebingen.de/Record/186613258X AB Within social learning theory, nonsocial reinforcement has been hypothesized to have a link with offending. The purpose of the present study was to address two questions: (1) Does nonsocial reinforcement change or remain stable over time? And (2) does nonsocial reinforcement have a reciprocal link with offending, as Wood et al. (1997) would expect? Methods: We used a subsample (N = 413) of the National Longitudinal Survey of Youth (NLSY) data and semi-parametric group-based modeling (SPGM). Results and Conclusions: The SPGM suggested three distinct groups of nonsocial reinforcement (one trajectory group appeared to have a low but stable rate of nonsocial reinforcement, one trajectory appeared to be higher but stable, another trajectory higher but also stable). A cross-tabulation of the nonsocial reinforcement trajectories and offending trajectories indicated that offending increased as nonsocial reinforcement became greater. Study limitations and implications are also discussed
