Abstract

Introduction The neural underpinnings underlying individual differences in nicotine-enhanced reward sensitivity (NERS) and smoking progression are poorly understood. Thus, we investigated whether brain resting-state functional connectivity (rsFC.) during smoking abstinence predicts NERS and smoking progression in young light smokers. We hypothesized that high rsFC between brain areas with high densities of nicotinic receptors (insula, anterior cingulate cortex [ACC], hippocampus, thalamus) and areas involved in reward-seeking (nucleus accumbens [NAcc], prefrontal cortex [PFC]) would predict NERS and smoking progression. Aims and Methods Young light smokers (N  = 64, age 18–24, M = 1.89 cigarettes/day) participated in the study. These individuals smoked between 5 and 35 cigarettes per week and lifetime use never exceeded 35 cigarettes per week. Their rsFC was assessed using functional magnetic resonance imaging after 14 hours of nicotine deprivation. Subjects also completed a probabilistic reward task after smoking a placebo on 1 day and a regular cigarette on another day. Results The probabilistic-reward-task assessed greater NERS was associated with greater rsFC between the right anterior PFC and right NAcc, but with reduced rsFC between the ACC and left inferior prefrontal gyrus and the insula and ACC. Decreased rsFC within the salience network (ACC and insula) predicted increased smoking progression across 18 months and greater NERS. Conclusions These findings provide the first evidence that differences in rsFCs in young light smokers are associated with nicotine-enhanced reward sensitivity and smoking progression. Clinical trial registration NCT02129387 (preregistered hypothesis: www.clinicaltrials.gov). Implications Weaker rsFC within the salience network predicted greater NERS and smoking progression. These findings suggest that salience network rsFC and drug-enhanced reward sensitivity may be useful tools and potential endophenotypes for reward sensitivity and drug-dependence research.

7. Examining Household Composition, Parental Style, and Consumer Socialization Practices Towards Children's Media Consumption.

Abstract

This study investigates the consumer socialization practices of parents in single versus multi-child and nuclear versus extended families in an emerging market. Previous consumer socialization research has focused primarily on western cultures. We examine parenting in a developing market and suggest that single-child families are more nurturant and maintain greater control of their children's media exposure than multi-child families. The findings indicate that Modal Indian consumer socialization practices may be shifting from an Authoritarian to an Authoritative parental style with greater maternal intervention in media exposure and support for regulating children's advertising. Implications for marketers, consumer educators, and public policy makers are discussed. [ABSTRACT FROM AUTHOR]
