Two main theories have been used to explain the arithmetic split effect: decision‐making process theory and strategy choice theory. Using the inequality paradigm, previous studies have confirmed that individuals tend to adopt a plausibility‐checking strategy and a whole‐calculation strategy to solve large and small split problems in complex addition arithmetic, respectively. This supports strategy choice theory, but it is unknown whether this theory also explains performance in solving different split problems in complex subtraction arithmetic. This study used small, intermediate and large split sizes, with each split condition being further divided into problems requiring and not requiring borrowing. The reaction times (RTs) for large and intermediate splits were significantly shorter than those for small splits, while accuracy was significantly higher for large and middle splits than for small splits, reflecting no speed–accuracy trade‐off. Further, RTs and accuracy differed significantly between the borrow and no‐borrow conditions only for small splits. This study indicates that strategy choice theory is suitable to explain the split effect in complex subtraction arithmetic. That is, individuals tend to choose the plausibility‐checking strategy or the whole‐calculation strategy according to the split size. 相似文献

Improvements in parenting skills do not necessarily lead to improvements in child and parent outcomes for children with attention deficit and hyperactivity disorder (ADHD). Cognitive factors such as parental cognitions and parenting self-efficacy may influence such outcomes. Clinical research on the effects of cognitive-behaviour therapy (CBT) on parental cognitions, parenting self-efficacy and mental health in Chinese parents of children with ADHD is lacking. This quasi-experimental study intended to assess the effects of a culturally attuned group CBT treatment on the mental health and quality of life of Chinese parents aged 26–58 years, with children with ADHD in Hong Kong. Participants in the experimental group received group CBT and standard treatment and their counterparts in the control group received standard treatment. Primary outcome variables of mental health and quality of life and process variables including parenting stress, parenting efficacy and dysfunctional attitudes were measured at baseline, post-treatment and 3-month follow-up. Data were analysed using 2?×?3 ANCOVAs, Cohen’s d statistics and multiple mediation analyses. Group by time interactions were found for most outcome variables. Effect size statistics indicated that group CBT had small to moderate effects on most outcome variables at post-treatment and follow-up assessments. The effect of CBT on mental health was mediated by the reduction in parenting stress and the effect of CBT on quality of life was mediated by the reductions in parenting stress and dysfunctional attitudes. Given its potential benefit, it is worth considering incorporating this group CBT programme into interventions for Chinese parents with ADHD children. 相似文献

恶性肿瘤作为我国的常见病、多发病,其死亡率高居首位.手术、化疗和放疗成为现代医疗对于癌症的常见治疗手段.中晚期癌症患者作为癌症临床诊疗对象的主体,常伴有各种慢性疾病或营养不良.从而,化疗、中药辅助巩固治疗及营养支持治疗成为中晚期癌症患者临床治疗过程中的主体.治疗方法决定给药途径,静脉输液成为了中晚期癌症患者治疗肿瘤的主要手段之一.然而中晚期肿瘤患者静脉穿刺难度大,易发生输液渗漏和静脉炎等特点,以及各种高浓度强刺激性药物和输液器材对静脉血管造成的损伤,都对中晚期癌症患者的疾病治疗产生了不同程度的不利影响.对于中晚期癌症患者来说,静脉保护的程度直接关系到患者疾病治疗的进程及享受到的生命质量.因此,医护人员应对静脉输液致血管损害的相关因素予以高度重视及时采取血管维护的对策,同时加强对输液患者进行静脉维护知识的宣教,促使其树立静脉护理的意识和能力. 相似文献

Dispositional traits and life narratives represent two different levels of personality that have not previously been empirically linked. The current study tested five hypotheses connecting Big-Five traits to life-narrative indices of emotional tone, theme, and structure. Students (Study 1) and adults (Study 2) completed a self-report measure of the Big-Five traits and provided extended written accounts of either ten (students) or eight (adults) key life-narrative scenes, including life high points, low points, and turning points. Content analysis of the narrative data revealed that for both samples Neuroticism was positively associated with an emotionally negative life-narrative tone, Agreeableness was correlated with narrative themes of communion (e.g., friendship, caring for others), and Openness was strongly associated with the structural complexity of life narrative accounts. Contrary to prediction, however, Conscientiousness was not consistently associated with themes of agency (e.g., achievement, self-mastery) and Extraversion was unrelated to positive narrative tone. The results are discussed in the context of contemporary research and theorizing on the narrative study of lives and the relation of narrative research in personality to more conventional, trait-based approaches. 相似文献

The fundamental premise of this paper is the primacy of the child's experience of biological-familial continuity in establishing his sense of self and personal significance. This paper examines the effects of current child placement practices on the child's ties to his biological, foster, and adoptive families. It explores alternative practices that would take into account biological-familial continuity.Comment is invited. 相似文献

Research on the impact of ex-romantic partners on current romantic relationships is mainly focused on negative aspects. Here instead we focus on the potential positive influence of reflecting on nostalgic memories of one's ex-partner. In three studies, we found that reflecting on nostalgic memories of one's ex-partner increased the perception of current relationship quality (Studies 1– 3) and approach motivation towards the current relationship (Study 3), compared to a control condition. We also tested a potential underlying mechanism—perception of self-growth. We found that perception of self-growth mediated the positive effects of reflecting on nostalgic memories about an ex-partner on perceived current relationship quality (Studies 2 and 3) and approach motivation in the current relationship (Study 3). Implications for research and therapy are discussed. 相似文献

We examined the effectiveness of the Qungasvik (Tools for Life) intervention in enhancing protective factors as a universal suicide and alcohol prevention strategy for young people ages 12−18 living in highly affected rural Alaska Native communities. Four communities were assigned to immediate intervention or to a dynamic wait list. Outcomes were analyzed for 239 young people at four time points over two years of community intervention. Outcomes assessed two ultimate variable protective factors buffering suicide and alcohol risk, and three intermediate variable protective factors at the individual, family, and community level. Dose dependent intervention effects were associated with growth in ultimate but not intermediate variables. This evaluation of the Qungasvik intervention provides support for the effectiveness of its Indigenous strategies for suicide and alcohol misuse prevention in this rural Alaska Native setting. Though findings did not provide support for a theory of change where growth in ultimate variables is occasioned through effects on intermediate variables, research designs focused on young people who enter intervention at lower levels of preexisting protection hold promise for better understanding of intervention change processes. The Qungasvik intervention is responsive to an acute public health need for effective rural Alaska Native suicide and alcohol risk prevention strategies. 相似文献

通过对情感决策的常用研究工具——标准爱荷华博弈任务进行了得失总量不变而频率改变的修改,并使之适合于年幼的3~5岁儿童,可以比较幼儿在不同奖惩频率任务中的表现,从而考察奖惩频率对幼儿情感决策的影响。对120名3~5岁幼儿在四种不同类型的任务中的表现进行分析后,所得实验结果如下:(1)儿童对惩罚和奖励频率的变化比较敏感:正向博弈任务中,"有利纸牌不变,不利纸牌的惩罚总量不变,只增加不利纸牌的惩罚频率"可以使3~5岁儿童完成博弈任务的成绩有显著提高;逆向博弈任务中,"不利纸牌不变,有利纸牌的奖惩总量不变,而有利纸牌奖励频率的增加"能促使4~5岁幼儿更多更快地做出正确选择。(2)幼儿的情感决策能力在3~4岁时期发展迅速,而在4~5岁时仍然有较快发展。 相似文献
