As a group, cigarette smokers exhibit blunted subjective, behavioral, and neurobiological responses to nondrug incentives and rewards, relative to nonsmokers. Findings from recent studies suggest, however, that there are large individual differences in the devaluation of nondrug rewards among smokers. Moreover, this variability appears to have significant clinical implications, since reduced sensitivity to nondrug rewards is associated with poorer smoking cessation outcomes. Currently, little is known about the neurobiological mechanisms that underlie these individual differences in the responsiveness to nondrug rewards. Here, we tested the hypothesis that individual variability in reward devaluation among smokers is linked to the functioning of the striatum. Specifically, functional magnetic resonance imaging was used to examine variability in the neural response to monetary outcomes in nicotine-deprived smokers anticipating an opportunity to smoke—circumstances found to heighten the devaluation of nondrug rewards by smokers in prior work. We also investigated whether individual differences in reward-related brain activity in those expecting to have access to cigarettes were associated with the degree to which the same individuals subsequently were willing to resist smoking in order to earn additional money. Our key finding was that deprived smokers who exhibited the weakest response to rewards (i.e., monetary gains) in the ventral striatum were least willing to refrain from smoking for monetary reinforcement. These results provide evidence that outcome-related signals in the ventral striatum serve as a marker for clinically meaningful individual differences in reward-motivated behavior among nicotine-deprived smokers.  相似文献

This essay reflects an ongoing dialogue between a clinician versed in mainstream psychological research and theory, and a social psychologist with experience both as a researcher and contributor to applied undertakings in various domains about the “incremental value” of research-based knowledge—that is, its value beyond that provided by the other sources of knowledge available to the practitioner. These sources include knowledge about the needs and coping strategies of all human beings, as well as knowledge both about the specific life circumstances of those one is seeking to help, and knowledge about language and culture. Examples from the clinical practice of the first author are offered, coupled with in-principle arguments about the underspecified and contingent nature of research-based generalizations. By way of rebuttal, examples of arguably useful findings are provided by the second author—especially findings that serve as correctives to biases in lay psychology (notably unwarranted “dispositionism”) and to widespread shortcomings in judgment and decision-making (particularly, Kahneman and Tversky’s work on “prospect theory” ). Both authors agree on the value of a “bricoleur” treatment strategy that relies on careful attention to the specifics of the case at hand and avoids one-size-fits-all applications of theory and prior research, and both agree that research-based findings are more useful in predicting behavior and designing intervention strategies that apply to groups and large samples of individuals rather than single actors. A concluding discussion focuses on necessary criteria and strategies for increasing the usefulness of laboratory and field research for the practitioner.  相似文献

Understanding how parents influence their child’s medical procedures can inform future work to reduce pediatric procedural distress and improve recovery outcomes. Following a pediatric injury or illness diagnosis, the associated medical procedures can be potentially traumatic events that are often painful and distressing and can lead to the child experiencing long-term physical and psychological problems. Children under 6 years old are particularly at risk of illness or injury, yet their pain-related distress during medical procedures is often difficult to manage because of their young developmental level. Parents can also experience ongoing psychological distress following a child’s injury or illness diagnosis. The parent and parenting behavior is one of many risk factors for increased pediatric procedural distress. The impact of parents on pediatric procedural distress is an important yet not well-understood phenomenon. There is some evidence to indicate parents influence their child through their own psychological distress and through parenting behavior. This paper has three purposes: (1) review current empirical research on parent-related risk factors for distressing pediatric medical procedures, and longer-term recovery outcomes; (2) consider and develop existing theories to present a new model for understanding the parent–child distress relationship during medical procedures; and (3) review and make recommendations regarding current assessment tools and developing parenting behavior interventions for reducing pediatric procedural distress.  相似文献

There has historically been much less research on the literacy skills of adolescents with emotional and behavioral disorders (EBD) compared to the amount of intervention research targeting their behavior. Within the limited literacy research available, there are multiple issues that need to be addressed, including (a) a predominant focus on children in elementary school, (b) gender differences in students with EBD, and (c) variation in the labels of research participants. The purpose of this integrative, comprehensive review was to investigate these concerns and provide a summary of the data to guide future research studies. A total of 63 articles targeting the reading and/or writing skills of middle and high school students with EBD were identified, spanning 37 years of research (1980–2016). Analysis of the articles revealed that less than 15% of the participants were female, and the percentage of females included in this research has declined across time; 11 different labels have been used to describe research participants; oral reading fluency, persuasive writing, and reading comprehension were the three most common dependent variables; and less than 5% of studies took place in inclusive general education settings. Recommendations for practitioners serving students with EBD and for researchers are discussed.  相似文献

Religious involvement has long been argued to have protective effects for negative behavioral health outcomes for vulnerable youth. This study builds on the existing resilience literature and need for more studies that examine protective factors associated with behavioral health. A sample of 638 low-income African American adolescents in Chicago to examine within group variations of the influence of religious involvement on delinquency, school engagement, substance use and sexual risk behaviors, and whether such relationships differ by gender, sexual orientation, and socioeconomic status. Logistic regression findings documented that greater religious involvement was protective with regards to lower rates of delinquency, drug use, risky sexual behaviors and higher rates of school engagement, and that gender, sexual orientation and socioeconomic status varied for several of these relationships. Overall findings are discussed with regards to future research.  相似文献

Our objective was to predict change in maternal stress over the course of a randomized clinical trial comparing the efficacy of two interventions for Oppositional Defiant Disorder (ODD): Parent Management Training and Collaborative & Proactive Solutions. In a secondary analysis of data collected from this randomized clinical trial, we examined whether children’s self-reported positive relations with their parents impacted responsiveness to treatment, which in turn impacted maternal stress. One hundred thirty-four children and their parents (38.1% female, ages 7–14, M age?=?9.51, SD?=?1.77) were tracked across three time points: pre-treatment; one-week post-treatment; and six-month post-treatment. Hierarchical linear models tested change in children’s reports of positive relations with parents, clinician reports of ODD severity, and maternal reports of parenting stress. Models then tested multilevel mediation from positive relations with parents, through ODD severity, onto maternal stress. Hypothesized indirect effects were supported such that children’s reports of positive views toward parents uniquely predicted reductions in ODD severity over time, which in turn uniquely predicted reductions in maternal stress. Results highlight the promise of potential secondary benefits for parents following interventions for children with oppositional problems. Furthermore, results underscore the importance of the parent–child relationship as both a protective factor and as an additional target to complement interventions for child disruptive behaviors.  相似文献
