潜艇环境对艇员认知功能和作业能力的影响

本研究运用基础心理实验仪器和国际标准的韦克斯勒成人智力、记忆量表(中国修订版),对海军某潜艇艇员和岸勤人员进行了部分认知功能和作业能力的逐个测量。通过对照研究,探讨了潜艇环境对艇员注意力、领悟力、记忆力和作业能力的影响特点。发现:(1)潜艇艇员选择反应时测验,对3种声音反应错误次数多,尤其是低音错误多,说明潜艇艇员的低音听觉和判断力受到了明显的影响,军龄大于5年的多期士官影响显著。(2)潜艇艇员注意集中能力测验,脱靶次数多,且只是军龄小于2年的士兵表现显著,注意分配能力测验中对光反应错误次数多,但随着军龄的增加影响不明显。(3)潜艇艇员领悟理解能力差,上艇5年以上是艇员领悟力开始受损的重要时期。(4)潜艇艇员双手协调和手指灵活用时较短,但出轨和掉针次数略多,艇员双手作业速度在潜艇的岗位训练中得到了增强,但因潜艇环境的不利影响其准确性有待提高。     

主人公的动机水平对句子理解中心理模拟的影响

通过两个实验, 考察了主人公的动机水平对句子理解中读者的心理模拟的影响。实验1采用移动窗口技术, 记录读者阅读句子中目的地词语的时间; 实验2采用视觉情景眼动范式, 主试播放描述运动的句子, 同时呈现相应的情境图片, 记录读者扫描图片中主人公、路径和目的地的时间。实验结果表明：(1)主人公的动机水平影响读者对目的地词语的阅读时间, 主人公的动机水平越高, 读者的阅读时间就越短; (2)读者对情景图片的扫描受主人公的动机水平影响, 主人公的动机水平越高, 读者对路径区域的扫描时间就越短, 对目的地区域的扫描时间就越长。两个实验均表明, 在句子的实时加工中, 读者可以通过再入情境, 遵循先内后外的顺序, 先模拟主人公的动机水平, 继而模拟主人公的动作, 从而影响对句子的注视和理解。研究结果支持语言加工的具身认知观。     

On feeling understood and feeling well: The role of interdependence

The present research examined whether people feel happier and healthier when they feel more understood in daily social interactions. A two-week diary study showed that people reported greater life satisfaction and fewer physical symptoms on days in which they felt more understood by others. Moreover, we found that individuals who tend to see themselves in relations to others (i.e., women or those scored high on interdependent self-construal measure) showed a stronger association between daily felt understanding and daily life satisfaction or physical symptoms. These findings demonstrate that daily social experiences, such as felt understanding, are associated with daily well-being, particularly for individuals with greater interdependent self-construal.     

临床思维的逻辑性

卫生法制建设是社会主义法治建设的必然要求,也是卫生与经济、社会协调发展的迫切需要;卫生法制建设需要确立科学的认识观和发展观,需要构架现代化发展战略目标。只有这样,才能务实地推进国家与地方区域的卫生法制现代化进程。     

On being stuck in time

It is sometimes claimed that non-human animals (and perhaps also young children) live their lives entirely in the present and are cognitively ‘stuck in time’. Adult humans, by contrast, are said to be able to engage in ‘mental time travel’. One possible way of making sense of this distinction is in terms of the idea that animals and young children cannot engage in tensed thought, which might seem a preposterous idea in the light of certain findings in comparative and developmental psychology. I try to make this idea less preposterous by looking into some of the cognitive requirements for tensed thought. In particular, I suggest that tensed thought requires a specific form of causal understanding, which animals and young children may not possess.

小学儿童羞耻情绪理解能力的发展

先通过收集和验证羞耻情境故事和情绪词来编制考察小学儿童羞耻情绪理解能力的测量材料,然后对300名1-6年级小学儿童的羞耻情绪理解能力的发展特点进行测查。结果表明：（1）小学儿童的羞耻情绪理解能力随年级增长而发展,并且在2-3年级有一个快速发展阶段。（2）4种羞耻情境中,小学儿童在公德情境中的羞耻情绪理解能力最高,其次是当众出丑情境和欺骗情境,最低是学习情境。（3）小学儿童的羞耻情绪理解能力无显著性别差异;4种羞耻情境中,只有在公德情境中的羞耻情绪理解能力有显著性别差异,即男生高于女生。     

幼儿情绪理解层次的发展及其与依恋的关系

采用情绪理解测验和儿童依恋行为卡片中文版,探讨幼儿在不同情绪理解层次上的发展特点,并考察其与依恋的关系。114名3～6岁儿童完成了测试。结果显示,不同层次的情绪理解随儿童年龄的增长不断发展:面部表情识别和情绪外因的发展时间相对较早,而混合情绪理解和道德情绪理解相对较晚;不同依恋类型儿童在不同情绪理解层次上存在差异:安全型依恋儿童在情绪理解总分以及情绪外因、基于愿望的情绪理解、基于信念的情绪理解、基于记忆的情绪理解任务的成绩均显著高于非安全型依恋儿童。     

Mirror Neurons and the Evolution of Embodied Language

ABSTRACT— Mirror neurons are a class of neurons first discovered in the monkey premotor cortex that activate both when the monkey executes an action and when it observes the same action made by another individual. These neurons enable individuals to understand actions performed by others. Two subcategories of mirror neurons in monkeys activate when they listen to action sounds and when they observe communicative gestures made by others, respectively. The properties of mirror neurons could constitute a substrate from which more sophisticated forms of communication evolved; this would make sense, given the anatomical and functional homology between part of the monkey premotor cortex and Broca's area (the "speech" area of the brain) in humans. We hypothesize that several components of human language, including some aspects of phonology and syntax, could be embedded in the organizational properties of the motor system and that a deeper knowledge of this system could shed light on how language evolved.     

Speech-associated gestures, Broca’s area, and the human mirror system

Speech-associated gestures are hand and arm movements that not only convey semantic information to listeners but are themselves actions. Broca’s area has been assumed to play an important role both in semantic retrieval or selection (as part of a language comprehension system) and in action recognition (as part of a “mirror” or “observation–execution matching” system). We asked whether the role that Broca’s area plays in processing speech-associated gestures is consistent with the semantic retrieval/selection account (predicting relatively weak interactions between Broca’s area and other cortical areas because the meaningful information that speech-associated gestures convey reduces semantic ambiguity and thus reduces the need for semantic retrieval/selection) or the action recognition account (predicting strong interactions between Broca’s area and other cortical areas because speech-associated gestures are goal-direct actions that are “mirrored”). We compared the functional connectivity of Broca’s area with other cortical areas when participants listened to stories while watching meaningful speech-associated gestures, speech-irrelevant self-grooming hand movements, or no hand movements. A network analysis of neuroimaging data showed that interactions involving Broca’s area and other cortical areas were weakest when spoken language was accompanied by meaningful speech-associated gestures, and strongest when spoken language was accompanied by self-grooming hand movements or by no hand movements at all. Results are discussed with respect to the role that the human mirror system plays in processing speech-associated movements.     

Young children's reports of when learning occurred

This study investigated young children's reports of when learning occurred. A total of 96 4-, 5-, and 6-year-olds were recruited from suburban preschools and elementary schools. The children learned an animal fact and a body movement. A week later, children learned another animal fact and another body movement and then answered questions about when the different learning events occurred. Responses of children who responded correctly to control questions about time supported the hypothesis that temporal distance questions would elicit more correct responses than would temporal location questions. Partial support was also found for the hypothesis that behavior learning would generate more correct reports than would fact learning. Implications for characterizations of children's developing understanding of knowledge and for applications of those characterizations in education and eyewitness testimony are discussed.
