Impulsive choice and pre‐exposure to delays: iv. effects of delay‐ and immediacy‐exposure training relative to maturational changes in impulsivity 下载免费PDF全文

Impulsive choice describes preference for smaller, sooner rewards over larger, later rewards. Excessive delay discounting (i.e., rapid devaluation of delayed rewards) underlies some impulsive choices, and is observed in many maladaptive behaviors (e.g., substance abuse, gambling). Interventions designed to reduce delay discounting may provide therapeutic gains. One such intervention provides rats with extended training with delayed reinforcers. When compared to a group given extended training with immediate reinforcers, delay‐exposed rats make significantly fewer impulsive choices. To what extent is this difference due to delay‐exposure training shifting preference toward self‐control or immediacy‐exposure training (the putative control group) shifting preference toward impulsivity? The current study compared the effects of delay‐ and immediacy‐exposure training to a no‐training control group and evaluated within‐subject changes in impulsive choice across 51 male Wistar rats. Delay‐exposed rats made significantly fewer impulsive choices than immediacy‐exposed and control rats. Between‐group differences in impulsive choice were not observed in the latter two groups. While delay‐exposed rats showed large, significant pre‐ to posttraining reductions in impulsive choice, immediacy‐exposed and control rats showed small reductions in impulsive choice. These results suggest that extended training with delayed reinforcers reduces impulsive choice, and that extended training with immediate reinforcers does not increase impulsive choice. 相似文献

Gay-Straight Alliances Vary on Dimensions of Youth Socializing and Advocacy: Factors Accounting for Individual and Setting-Level Differences 下载免费PDF全文

Gay‐Straight Alliances (GSAs) are school‐based youth settings that could promote health. Yet, GSAs have been treated as homogenous without attention to variability in how they operate or to how youth are involved in different capacities. Using a systems perspective, we considered two primary dimensions along which GSAs function to promote health: providing socializing and advocacy opportunities. Among 448 students in 48 GSAs who attended six regional conferences in Massachusetts (59.8 % LGBQ; 69.9 % White; 70.1 % cisgender female), we found substantial variation among GSAs and youth in levels of socializing and advocacy. GSAs were more distinct from one another on advocacy than socializing. Using multilevel modeling, we identified group and individual factors accounting for this variability. In the socializing model, youth and GSAs that did more socializing activities did more advocacy. In the advocacy model, youth who were more actively engaged in the GSA as well as GSAs whose youth collectively perceived greater school hostility and reported greater social justice efficacy did more advocacy. Findings suggest potential reasons why GSAs vary in how they function in ways ranging from internal provisions of support, to visibility raising, to collective social change. The findings are further relevant for settings supporting youth from other marginalized backgrounds and that include advocacy in their mission. 相似文献

The salience map is a crucial concept for many theories of visual attention. On this map, each object in the scene competes for selection - the more conspicuous the object, the greater its representation, and the more likely it will be chosen. In recent years, the firing patterns of single neurons have been interpreted using this framework. Here, we review evidence showing that the expression of salience is remarkably similar across structures, remarkably different across tasks, and modified in important ways when the salient object is consistent with the goals of the participant. These observations have important ramifications for theories of attention. We conclude that priority--the combined representation of salience and relevance--best describes the firing properties of neurons. 相似文献

This study examines whether availability of mental health resources in the county of residence is associated with subsequent suicidal behavior after a previous suicide attempt. Among 10,922 individuals who attempted suicide in Colorado between 1998 and 2002, residence in a county that offered a minimum safety-net of mental health services significantly reduced the risk of suicidal behavior for at least 1 year after the index attempt. Safety-net services included mental health treatment, crisis treatment, and case management. These results suggest one strategy for prevention of suicidal behavior that could inform state-level health policy development and resource allocation. 相似文献

What effect does witnessing other students cheat have on one's own cheating behavior? What roles do moral attitudes and neutralizing attitudes (justifications for behavior) play when deciding to cheat? The present research proposes a model of academic dishonesty which takes into account each of these variables. Findings from experimental (vignette) and survey methods determined that seeing others cheat increases cheating behavior by causing students to judge the behavior less morally reprehensible, not by making rationalization easier. Witnessing cheating also has unique effects, controlling for other variables. 相似文献

Lutheran theological discussions over the morality of same‐sex sexuality not only raise “ethical” questions, but point to deeper interpretive tensions that arise when resources of the tradition are interpreted in new contexts. Responding to these debates, in this article I propose that Luther's application of the law to challenging ethical situations provides a historically situated hermeneutic that can redirect theological discussions on same‐sex sexuality. Drawing upon feminist Lutheran and queer theological work, I consider how we may reengage with Luther in a way that is both faithful to his commitments, and also takes queer people seriously as moral subjects. 相似文献

Minnesota Multiphasic Personality inventory (MMPI) norms developed by Marks and Briggs (1967/1972) have served as the standard adolescent norms used for over 10 years. Additional adolescent, norms, have recently been produced by Gottesman, Hanson, Kroeker, and Briggs (1987) and by Colligan and Offord (1989), thereby providing MMPI users with a potential choice of adolescent norms. Our study examines the effects of these adolescent norm sets on single-scale and profile elevations. In addition, we examine the ability of these norm sets to generate T-score values that would serve to discriminate accurately among adolescents in outpatient (n = 100), inpatient (n = 100), and normal (n = 100) settings. Results indicated teat the choice of adolescent norms resulted in important differences in profile elevation. Findings from the discriminant function analyses, however, indicated that these normative sets were roughly equivalent in discriminating among adolescents in the three settings. 相似文献
