中文双音节词视觉识别与短时记忆保持量 总被引:3,自引:0,他引:3
两个实验探讨了汉语双音节词的使用度、笔画复杂性与发音长短对短时记忆保持量的影响。结果表明发音长度显著不同的词在记忆保持量上无显著差别;使用度和笔画复杂性对短时记忆保持量有显著影响;笔画复杂性不同的词识别时间与其记忆保持量有显著负相关。最后讨论了笔画复杂性的短时记忆量与词的识别阶段的可能关系。 相似文献

The relationship between creativity and executive control has long been controversial. Some researchers view creative thinking as a defocused process with little executive control involvement, whereas others claim that executive control plays a vital role in creative thinking. In this study, we focused on one subcomponent of executive control, cognitive shifting, and examined its relationship with creativity by using latent variable analysis and structural equation modeling. We also analyzed whether this relation was mediated by intelligence. The results showed that: (a) cognitive shifting ability had a positive relationship with creativity, but only on the quantitative aspects (fluency and flexibility); (b) Intelligence had a positive relationship with both quantitative and qualitative aspects (originality) of creativity, and its effect on qualitative aspect was stronger than that on the quantitative aspect; (c) There was a mediating effect of intelligence on the relationship between creativity cognitive and shifting. 相似文献

Bimanual coordination is a commonplace activity, but the consequences of using both hands simultaneously are not well understood. The authors examined fingertip forces across 4 experiments in which participants undertook a range of bimanual tasks. They first measured fingertip forces during simultaneous lifts of 2 identical objects, noting that individuals held the objects with more force bimanually than unimanually. They then varied the mass of the objects held by each hand, noting that when both hands lifted together performance was equivalent to unimanual lifts. The authors next measured one hand's static grip force while the other hand lifted an object. They found a gradual reduction of grip force throughout the trial, but once again no evidence of one hand influencing the other. In the final experiment the authors tested whether tapping with one hand could influence the static grip force of its counterpart. Although the authors found no changes in static grip force as a direct consequence of the other hand's actions, they found clear differences from one task to the other, suggesting an effect of task instruction. Overall, these results suggest that fingertip forces are largely independent between hands in a bimanual lifting context, but are sensitive to different task requirements. 相似文献

本研究基于双重认知控制理论,通过比较学困组和对照组在持续性操作任务上的表现来探究学习困难青少年的认知控制特点。结果发现:(1)在反应性控制的指标上,学困组和对照组的反应时和正确率不存在显著差异,但学困组对探测刺激的辨别力指数更低,显示学困组的反应性控制能力存在一定不足;(2)在主动性控制的指标上,学困组的反应时更长、正确率更低,且对线索刺激的辨别力指数更低,显示学困组在对线索刺激保持的各项指标上都比对照组更差,说明学困组在主动性控制上的缺陷更为明显。 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
