Using Conger’s family stress model as a theoretical framework, a series of mediated associations among economic hardship, perceived economic pressure, parental depression, marital conflict, psychologically controlling parenting, and children’s reticent behaviors in Romanian families were studied. The sample consisted of 121 Romanian mothers and fathers of 4–5-year-old children. Children’s kindergarten teachers living in urban and rural locations evaluated child reticence. Findings generally support the family stress model. Structural equation modeling showed that after controlling for living in a rural location, economic pressure was indirectly linked with marital conflict through depression. Depression was indirectly related to psychological control through marital conflict, and marital conflict was indirectly linked to child reticence through psychological control. Directions for future research and recommendations for interventions and public policy are described.  相似文献

The primary aim of this paper is to conceptualise the influence of shopper religiosity on perceived risk and the moderating role of moral potency when purchasing religiously questionable products from retailers. An extensive review of extant literature was undertaken, drawing together the General Theory of Marketing Ethics and the concept of moral potency, in a retail context. A conceptual model is developed that provide the basis for future inquiry. The model elucidates the complex relationships between the dimensions of religiosity and social and psychological risk and then explains the moderating role of moral potency. The model offers a strong psychological explanation of how a shoppers' religion may increase their perceptions of risk in a purchase situation. The model also argues that risk perceptions may be heightened (or lessened) as a result of the shoppers' personal responsibility, confidence and courage. Retail managers may choose to implement this model in order to better predict shopper adoption behaviour of new religiously questionable products. The model allows for future empirical examinations across multiple shopping contexts and may be employed to estimate levels' demand for new products based on the extent of religiosity, moral potency and risk. The role of religion within retailing and shopping behaviour is emergent. Extant retailing literature has previously overlooked the role of religion as an antecedent to risk and the role of moral potency in moderating that relationship. This is the first paper to highlight these gaps and propose a testable model. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

Despite an increasing focus over the past 2 decades by federal and state governments on the care of persons with severe mental illness, psychologists remain underrepresented among behavioral health professionals working with this population. Within the discipline there is growing concern about the need to adequately train, recruit, and retain psychologists in this specialty. This is a particular concern in academic medical settings where the overall severity of illness among those receiving psychiatric services continues to increase. The purpose of this qualitative research study was to intensively examine the experience of predoctoral interns engaged in treating individuals with severe mental illness in an academic medical center in order to identify the professional developmental experiences and training needs of those learning to care for this population. This analysis, conducted with semistructured interviews at four points during the internship year, yielded a series of recommendations for improving internship training and recruiting psychologists to this specialty.  相似文献

Despite abundant evidence that systemic administration of adrenergic drugs and hormones can produce retrograde memory enhancement, the literature contains no clear demonstration that postlearning systemic administration of adrenergic antagonists produces retrograde amnesia. Here we demonstrate retrograde amnesia for a stressful learning task (a spatial water maze) with systemic administration of the β-adrenergic antagonist propranolol (5 mg/kg). The amnesic effect of the drug depended on the degree of learning in the subjects: Propranolol caused a robust retrograde amnesia in “good learners,” but did not significantly affect memory in “poor learners.” The findings provide critical additional support for the hypothesis that postlearning adrenergic activation modulates memory consolidation processes after emotionally stressful events and help explain previous failures to detect memory impairment after systemic administration of adrenergic blocking drugs.  相似文献

The acquisition of skills by individuals with developmental disabilities typically includes the attainment of a certain mastery criterion. We conducted a survey of practitioners who indicated the most commonly used mastery criterion as 80% accuracy across three consecutive sessions. Based on these results, we conducted a series of three experiments to evaluate the relation between mastery criterion and subsequent skill maintenance with 4 individuals with various developmental disabilities. Results suggest that 80% accuracy across three consecutive sessions may be insufficient for producing maintenance in some cases.  相似文献

In Colombia, many adolescents have experienced violence related to the decades‐long armed conflict in the country and have witnessed or been directly victimized by violence in their communities, often related to gang activity or drug trafficking. Exposure to violence, both political and community violence, has detrimental implications for adolescent development. This study used data from 1857 Colombian adolescents in an urban setting. We aim to understand the relations between exposure to violence and adolescent outcomes, both externalizing behaviors and developmental competence, and then to understand whether school climate (i.e., safety, connectedness, services) moderates these relations. Results demonstrate that armed conflict, community violence victimization, and witnessing community violence are positively associated with externalizing behaviors, but only armed conflict is negatively associated with developmental competence. School safety, connectedness, and services moderate the relation between community violence witnessing and externalizing behaviors. School services moderates the relation between community violence victimization and developmental competence. As students perceived more positive school climate, the effects of community violence exposure on outcomes were weakened. This study identifies potential levers for intervention regarding how schools can better support violence‐affected youth through enhancements to school safety, connectedness, and services.  相似文献

The degree to which social norms are processed by a unitary system or dissociable systems remains debated. Much research on children’s social-cognitive judgments has supported the distinction between “moral” (harm/welfare-based) and “conventional” norms. However, the extent to which these norms are processed by dissociable neural systems remains unclear. To address this issue, 23 healthy participants were scanned with functional magnetic resonance imaging (fMRI) while they rated the wrongness of harm/welfare-based and conventional transgressions and neutral vignettes. Activation significantly greater than the neutral vignette baseline was observed in regions implicated in decision-making regions including rostral/ventral medial frontal, anterior insula and dorsomedial frontal cortices when evaluating both harm/welfare-based and social-conventional transgressions. Greater activation when rating harm/welfare-based relative to social-conventional transgressions was seen through much of ACC and bilateral inferior frontal gyrus. Greater activation was observed in superior temporal gyrus, bilateral middle temporal gyrus, left PCC, and temporal-parietal junction when rating social-conventional transgressions relative to harm/welfare-based transgressions. These data suggest that decisions regarding the wrongness of actions, irrespective of whether they involve care/harm-based or conventional transgressions, recruit regions generally implicated in affect-based decision-making. However, there is neural differentiation between harm/welfare-based and conventional transgressions. This may reflect the particular importance of processing the intent of transgressors of conventional norms and perhaps the greater emotional content or salience of harm/welfare-based transgressions.  相似文献

The current studies utilized drift diffusion modeling (DDM) to examine how reinforcement and stimulant medication affect cognitive task performance in children with ADHD. In Study 1, children with (n = 25; 88 % male) and without ADHD (n = 33; 82 % male) completed a 2-choice discrimination task at baseline (100 trials) and again a week later under alternating reinforcement and no-reinforcement contingencies (400 trials total). In Study 2, participants with ADHD (n = 29; 72 % male) completed a double-blind, placebo-controlled trial of 0.3 and 0.6 mg/kg methylphenidate and completed the same task utilized in Study 1 at baseline (100 trials). Children with ADHD accumulated information at a much slower rate than controls, as evidenced by a lower drift rate. Groups were similar in nondecision time and boundary separation. Both reinforcement and stimulant medication markedly improved drift rate in children with ADHD (ds = 0.70 and 0.95 for reinforcement and methylphenidate, respectively); both treatments also reduced boundary separation (ds = 0.70 and 0.39). Reinforcement, which emphasized speeded accuracy, reduced nondecision time (d = 0.37), whereas stimulant medication increased nondecision time (d = 0.38). These studies provide initial evidence that frontline treatments for ADHD primarily impact cognitive performance in youth with ADHD by improving the speed/efficiency of information accumulation. Treatment effects on other DDM parameters may vary between treatments or interact with task parameters (number of trials, task difficulty). DDM, in conjunction with other approaches, may be helpful in clarifying the specific cognitive processes that are disrupted in ADHD, as well as the basic mechanisms that underlie the efficacy of ADHD treatments.  相似文献

The objective of this study is to investigate cognitive and attentional function in adolescents and young adults with operated congenital heart disease. Previous research has indicated that children with congenital heart disease have deficits in broad areas of cognitive function. However, less attention has been given to survivors as they grow into adolescence and early adulthood. The participants were 18 non-syndromic adolescents and young adults with tetralogy of Fallot and d-transposition of the great arteries that required cardiac surgery before the age of 5 years, and 18 healthy, unaffected siblings (11–22 years of age for both groups). Cases with congenital heart disease and their siblings were administered Wechsler Intelligence scales and reported attention problems using the Achenbach System of Empirically Based Assessments. Cases were compared to both healthy siblings and established norms. Cases performed significantly lower than siblings on full scale IQ and processing speed, and significantly lower than norms on perceptual reasoning. Cases also reported more attention problems compared to both siblings and norms. Effect sizes varied with medium-to-large effects for processing speed, perceptual reasoning, working memory, and attention problems. Findings suggest that neurocognitive function may continue to be affected for congenital heart disease survivors in adolescence and young adulthood, and that comparisons to established norms may underestimate neurocognitive vulnerabilities.  相似文献
