Parenting,Effortful Control,and Adolescents’ Externalizing Problem Behavior: Moderation by Dopaminergic Genes

Research shows that genetics and effortful control play an important role in the link between parenting and problem behavior. However, little is known about how these factors act simultaneously. This article used a moderated mediation model to examine whether effortful control mediated the link between parenting and externalizing problem behavior, and whether dopaminergic genes (i.e., polygenic index score including DAT1, DRD2, DRD4, COMT) moderated this link. Two three-wave studies were conducted on community samples (adolescents: Study 1: N?=?457; M_age?=?15.74; Study 2: N?=?221; M_age?=?12.84). There was no mediation by effortful control, but a moderation by dopaminergic reactivity was observed. Despite inconsistent evidence, this article indicates that the development of externalizing problem behavior is subject to genetic characteristics and parenting.

     

Determinants of State Economic Perceptions

Despite a greatly increased emphasis on state economic development, citizens' perceptions of state economic conditions have been infrequently studied, leaving a serious question as to how well citizens distinguish between national and state economic performance. We investigate the sources of state economic perceptions using data from 1990 Voter Research and Surveys exit polls of 23 states along with measures of state economic conditions. We find strong support for the proposition that perceptions of state and national economies are distinct phenomena. We also find that state economic perceptions are well grounded in economic reality—that is, in the conditions of the state economy. Finally, we show that state economic perceptions are based on a variety of indicators, including measures that have not heretofore been included in models of economic voting.
