采用追踪研究考察258名学前儿童执行功能与语言的双向关系,及二者关系是否受社会经济地位调节。交叉滞后结果表明,学前儿童语言发展与执行功能三个子成分(抑制控制、认知灵活性、工作记忆)存在双向关系;T1时儿童语言对T2时认知灵活性的预测作用受家庭社会经济地位调节:在高社会经济地位家庭中,T1时间儿童的语言能显著正向预测T2时认知灵活性,低社会经济地位家庭中预测作用不显著;其余双向关系中调节作用均不显著。本研究表明,学前儿童执行功能三个子成分与语言均存在双向关系,且社会经济地位在部分关系中起到调节作用。 相似文献

微表情是一种持续时间极短、不易被察觉的面部动作, 揭示了个体的真实情绪, 可以被广泛地应用于谎言识别等领域。而微表情检测的研究受到小样本问题的限制。针对该问题, 本文结合计算机视觉技术与认知心理学实验方法进行探索。首先, 结合眼动技术和呈现-判断范式与阈下情绪启动效应的行为实验范式, 考察微表情识别中选择注意分配的认知机制, 细化人类识别微表情时的特征兴趣区域。其次, 结合人类注意机制, 提出基于自监督学习的多模态微表情检测方法。通过理论和关键技术的突破, 为真实场景下微表情检测的应用奠定基础。 相似文献

Three intersection mechanisms with the gliding planes (111)TB, (001)TB and (115)TB respectively have been observed by high-resolution electron microscopy in the type-I twin intersection of gamma-TiAl. It was found that the intersection mechanism that occurred was related to the thickness of the incident twin. The accommodation mechanism on the (111)TB atomic plane is preferred when the incident twin becomes very thin. The dislocation dissociations of the (111)TB plane accommodation are the most energetically unfavourable of the dissociations of the three intersection mechanisms; however, the resultant dislocations on the (111)TB planes are the easiest to propagate away from the intersection area. Accordingly, (111)TB atomic plane accommodation is considered to be the only mechanism allowing shear transmission under the small local stress of the pile-up of the incident twinning partials. 相似文献

The alpha -> beta polytypic transformation in SiC was observed during ball milling at room temperature. Microstructural evolution was characterized on an atomic scale by high-resolution electron microscopy (HREM). HREM observations showed that partial dislocations play an important role in the transformation under the complicated conditions during ball milling. 相似文献

口腔疾病有时表现并不典型,需要医生拥有强烈的责任心,对患者详细问诊和检查,方能得出正确结论,避免误诊给患者带来身心痛苦。笔者在以下几个方面对误诊原因进行了深层次的分析:(1)医生缺乏批判性思维;(2)医生的人文关怀精神不够;(3)医生对医患沟通重视不够;(4)专科医生往往思路狭隘。通过对3例临床误诊患者就医过程的介绍和分析,再一次提醒广大口腔医务工作者,在临床工作中要重视详细问诊,仔细查体,不断拓展临床其他学科知识,避免思路狭隘和惯性思维。 相似文献

Previous evidence had revealed gender differences in perception of pain and its socialization. The present research studies gender differences by mapping the central structure core in social representation of pain. Eighty males and eighty females participated in a free evocation task for collecting cognitive elements of “pain.” By defining the elements as nodes and their co‐occurrences as lines, structural characteristics of social representation are analyzed by network analysis. Females have a central structure core in their network structure of social representation of pain. In contrast, males have no such core. These results suggest gender differences in socialization processes around the concept of pain and extend practical methods for studies of the central nucleus theory of social representation. 相似文献

Does temporary mood influence how fair or selfish we are in interpersonal situations? These three experiments predicted and found that when people have the power to allocate scarce resources between themselves and others in the dictator game, positive mood increased selfishness, and sad mood produced greater fairness. In a public setting (Experiment 1), happy persons kept more raffle tickets to themselves when making allocations, and Experiment 2 confirmed this effect in the laboratory. Experiment 3 showed that mood effects on selfishness were strongest when the external norms for fairness were relaxed. The results are discussed in terms recent affect-cognition theories, suggesting that positive mood recruits more assimilative, internally focused processing, while negative affect promotes more externally oriented, accommodative processing and thus greater concern with social norms. The implications of the findings for everyday interpersonal decisions are considered. 相似文献

强化治疗是最近几年反复提到的话题。很多临床试验研究各种强化治疗对心血管疾病预后的影响,但结果显示强化治疗并未能带来更多的益处,甚至有害。因此我们必须理性地看待这些所谓的强化治疗。更应该倾向于个体化治疗、综合治疗,包括控制各种危险因素,改善生活的方式。把治疗的眼光放到疾病发生的早期,早治疗,以求更多获益。 相似文献
