采用改进的点–探测范式,考察熟练双语者在情绪注意偏向中对情绪信息加工的优势效应及该效应产生的原因。采用2(熟练双语者和非熟练双语者)×3(靶刺激与消极词汇出现的位置一致、不一致和中性条件)×2(线索呈现时间为100 ms和400 ms)的混合实验设计,记录被试对靶子的按键反应时和错误率。结果发现:线索呈现100 ms和400 ms时,两组被试在注意定向分数上无显著差异;线索呈现100 ms时,两组被试的注意解除分数无显著差异;线索呈现400 ms时,熟练双语者的注意解除分数显著小于非熟练双语者。结果表明,在情绪注意偏向任务中,熟练双语者比非熟练双语者表现出了对情绪词汇信息更好的注意抑制控制能力,体现出对情绪信息加工的双语优势效应,产生这一优势效应的原因是熟练双语者在注意的晚期阶段比非熟练双语者具有更好的情绪信息注意解除能力。 相似文献

Rheumatoid arthritis (RA) prevalence increases with age and old people are special patient population. The recognition of functional disability related to RA could be challenging in elderly patients because aging itself and potential co-morbid disease may also cause functional disability. In this study, we aimed to look at the correlation between disease activity and functional disability in elderly RA patients. Elderly RA patients, ≥65 years old at their routine visits were included in the study. The composite ‘disease activity score’ in 28 joints (DAS-28) was used to determine disease activity groups. Health assessment questionnaire (HAQ) scores were calculated to describe the functional disability and compared across the disease activity groups. Two hundred and fifty-eight RA patients with the mean age of 71 ± 5 (65–90) and a total disease duration of 8.4 ± 8.5 (.5–50) years were recruited. The proportion of patients with high and moderate disease activity was 70%. HAQ scores were significantly correlated with disease activity (p < .05). Functional disability estimated by HAQ was correlated with disease activity in elderly patients with RA 相似文献

研究采用同伴提名法、教师和家长报告法,对农村135名一年级小学生进行了为期一年的追踪调查,在此基础上,考察了学前教育年限、母亲受教育水平与学校适应之间的关系。结果表明:(1)学前教育年限越长,小学生越多地表现出积极社会行为,但这种优势仅体现在小学入学初期;(2)母亲受教育水平越低,小学生越多地表现出敏感退缩行为和受拒绝同伴关系;(3)对于母亲受教育水平较低的小学生,学前教育年限越长,其攻击冒犯行为越多;而对于母亲受教育水平较高的小学生,学前教育年限越长,其攻击冒犯行为越少。可见,母亲受教育水平与学前教育年限相互作用,共同影响儿童发展结果,且母亲受教育水平的影响作用更为明显。 相似文献

The ability to inhibit unproductive motor responses triggered by salient stimuli is a fundamental inhibitory skill. Such motor self-regulation is thought to underlie more complex cognitive mechanisms, like self-control. Recently, a large-scale study, comparing 36 species, found that absolute brain size best predicted competence in motor inhibition, with great apes as the best performers. This was challenged when three Corvus species (corvids) were found to parallel great apes despite having much smaller absolute brain sizes. However, new analyses suggest that it is the number of pallial neurons, and not absolute brain size per se, that correlates with levels of motor inhibition. Both studies used the cylinder task, a detour-reaching test where food is presented behind a transparent barrier. We tested four species from the order Psittaciformes (parrots) on this task. Like corvids, many parrots have relatively large brains, high numbers of pallial neurons, and solve challenging cognitive tasks. Nonetheless, parrots performed markedly worse than the Corvus species in the cylinder task and exhibited strong learning effects in performance and response times. Our results suggest either that parrots are poor at controlling their motor impulses, and hence that pallial neuronal numbers do not always correlate with such skills, or that the widely used cylinder task may not be a good measure of motor inhibition. 相似文献
