Parent Cognitions as Predictors of Child Treatment Response in Attention-Deficit/Hyperactivity Disorder

Using a subsample of 105 children and their parents (100 mothers, 57 fathers) from the Multimodal Treatment Study of Children with ADHD (the MTA), the value of parents' baseline cognitions as predictors of children's treatment outcome at 14 months was examined. Measures of parents' cognitions about themselves, their ADHD children, and their parenting, as well as a self-report measure of dysfunctional discipline were included. Both mothers' and fathers' self-reported use of dysfunctional discipline predicted worse child treatment outcome. Low self-esteem in mothers, low parenting efficacy in fathers, and fathers' attributions of noncompliance to their ADHD child's insufficient effort and bad mood also were associated with worse child treatment outcome. All of these predictive relations were obtained even after MTA treatment effects had been taken into account. Secondary analyses indicated that mothers had a more external locus of control, lower self-esteem, lower parenting efficacy, and a greater tendency to attribute noncompliance to their ADHD child's bad mood than did fathers.     

Oral drug self-administration in rhesus monkeys: interactions between drug amount and fixed-ratio size.

During daily 3-hr sessions, 5 rhesus monkeys drank drug solutions and water that were concurrently available. The drug solutions were: 1 milligram per milliliter (mg/mL) pentobarbital (2 monkeys), 1 mg/mL pentobarbital plus 0.5% ethanol (1 monkey), 1 mg/mL pentobarbital plus 1% ethanol (1 monkey), and 8% ethanol (1 monkey). The drug solution and water were available under identical two-component tandem fixed-ratio continuous-reinforcement N schedules. Two variables were manipulated: the size of the fixed-ratio component and the number of liquid deliveries (N) in the second component. Deliveries of the drug solution maintained higher rates of responding than did deliveries of the drug vehicle, water. The number of drug deliveries per session increased with increases in the number of deliveries per fixed ratio and decreased with increases in fixed-ratio size. Analysis of the results in terms of the proportion of deliveries to responses showed that the number of drug deliveries per session was directly related to the size of this quotient. Finally, when fixed-ratio size was repeatedly doubled, the following orderly relationship emerged: The greater the number of available drug deliveries per fixed ratio, the less was the percent decrease in the number of fixed ratios completed per session. It was concluded that increases in the number of liquid deliveries per fixed ratio resulted in increases in reinforcing efficacy.     

Cocaine and food as reinforcers: effects of reinforcer magnitude and response requirement under second-order fixed-ratio and progressive-ratio schedules.

Reinforcer magnitude and fixed-ratio requirement were varied under two second-order schedules. Under one, the first sequence of a fixed number of responses completed after the lapse of a 10-min fixed interval produced reinforcement. Under the second, a second-order progressive-ratio schedule, the fixed number of responses increased after each reinforcement. Either cocaine (0 to 300 micrograms/kg/inj) or food (0 to 5,700 mg/delivery) reinforcers were delivered. Under some conditions, a 2-s illumination of stimulus lights occurred on completion of each ratio sequence. Under the second-order schedule, as cocaine dose or amount of food increased, rates of responding increased; at the highest values, rates of responding decreased. Increases in the ratio requirement from 10 to 170 responses minimally decreased overall response rates. Under the second-order progressive-ratio schedule, increases in dose of cocaine or amount of food increased rates of responding; at the highest amounts of food, rates of responding decreased but response rates at the highest dose of cocaine remained relatively high. The highest ratio requirement that was completed (breaking point) depended on the dose of cocaine but was less dependent on the amount of food. Removing brief-stimulus presentations had a greater effect on completion of ratio requirements with cocaine compared to food.     

The efficacy of postdivorce intervention programs for children: A meta-analytical review

Preventive postdivorce interventions aim to help children cope with divorce and promote their adjustment. Nevertheless, questions remain regarding the concrete outcomes of these interventions and the intervention characteristics that influence them. This meta-analysis of 30 studies analyzes the efficacy of postdivorce interventions on children's symptomatology, personal resources, and adaptation to divorce. Likewise, it explores whether the intervention impacts the putative mediators from the family context and whether the characteristics of the studies themselves also influence the results. Using a data set of N = 4344 individuals, 258 effect sizes were calculated. Random effects analyses evidenced the impact of the interventions on specific variables instead of on children's global adjustment. There were no significant effects on children's mental health outcomes, and none of these effects were qualified by the moderators that were examined. Preventive postdivorce interventions had significant effects, specifically on children's divorce adjustment and self-esteem. The study of the moderators found that the interventions were generally homogeneous, and only one of the 20 moderators examined had a significant effect. Based on children's age, the interventions had an impact on family functioning only when they involved younger children, but this result should be interpreted with caution due to the small sample of studies. This meta-analysis provides evidence of the relevance of postdivorce interventions to critical variables as well as information about the role of the intervention characteristics in the effects and makes suggestions for future research on divorce interventions that encompass both practical and empirical developments.

领悟社会支持、应对效能和压力性生活事件对青少年学业成就的影响机制

为揭示领悟社会支持与青少年学业成就的关系,以及应对效能的中介效应和压力性生活事件的调节效应,采用领悟社会支持问卷、应对效能问卷、压力性生活事件量表和学业成就问卷对1687名青少年进行研究。结果显示：（1）领悟社会支持能够促进青少年的学业成就;（2）应对效能对领悟社会支持与学业成就的关系具有中介效应;（3）压力性生活事件能够调节应对效能的中介作用。因此,领悟社会支持对学业成就的影响是有调节的中介效应。     

Constructing the Citizen

Discussions of citizenship and citizenship education have been conducted largely within the worldview of stable, Western societies and have been based on psychological models that emphasize individual cognition. The concepts of citizenship that evolved in this context have become taken for granted. But during the past decade, different concepts of citizenship have arisen from emergent democracies, from societies in transition, from the dissolution of the left-right spectrum in Western society, and from a changing perspective in psychological theory that attends to language and to social and cultural context. These developments have implications for defining the goals of citizenship education and for formulating educational programs, particularly in relation to identity, positioning, narratives, and efficacy.     

情绪对不同智力水平学生推理操作的影响

本研究试图探讨三种情绪状态(喜悦、中性、悲伤)对13岁不同智力水平学生思维推理操作(简单、一般、复杂)的影响及相互关系。研究表明,在简单和中等推理中,喜悦对优等、中等智力组的推理起更大的促进作用;在较高难度推理中,优等智力组受喜悦情绪的干扰,悲伤对不同智力组都产生干扰作用。对优等智力组而言,情绪强度(由负到正的变化)与智能操作活动效果之间的关系符合耶尔克斯—道森定律,即优等智力组在完成较复杂推理中以中性情绪为最佳;中等智力组和中下等智力组的操作效果不符合该定律。
