微创心脏外科的发展与思考

微创心脏外科是心脏外科发展的必然趋势,其中蕴含丰富的人文关怀精神,体现了人文关怀的精神实质.在临床工作中,应该以"以人为本"的人文关怀精神实质为指导,辩证地采用微创心脏外科手术,实现人文关怀.     

医务人员言语偏误的伦理评介

通过具体临床言语资料的分析,发现医惠交际中存在着言语信息失量、言语态度失衡、言语策略失慎和言伴信息失却等问题.医务人员对患者缺乏必要的人文关怀和伦理照应是问题产生的关键.加强医务人员的言语伦理修养,是对传统医学伦理的尊重,也是新形势下促进医惠关系和谐发展的一项重要举措.     

自闭症儿童依恋及其与功能领域关系的研究

以中国大陆16个特殊儿童康复机构的278名自闭症儿童作为研究对象,通过问卷法探讨自闭症儿童的依恋及其与功能领域的关系。结果发现:(1)自闭症儿童依恋总体水平偏低;(2)自闭症儿童依恋与各个功能领域的发展有着极为紧密的联系;(3)影响自闭症儿童总体依恋发展水平的因素是儿童自身的障碍程度,具体取决于交往、认知、感觉、生活自理等功能领域的发展情况。     

How health information affects college students’ inclination toward variety‐seeking tendency

Chien‐Huang, L. & Hung‐Chou, L. (2010). How health information affects college students’ inclination toward variety‐seeking tendency. Scandinavian Journal of Psychology 51, 503–508. College students often consume too much snacks (e.g. potato chips) and such high‐fat snacks are found to be related to obesity. This paper seeks to explore the effect of health‐related information on the relationship of mood states and variety seeking (VS) behavior among enjoyable snacks. Health warnings and nutritional labeling are used to examine the moderating effects on this relationship. Consistent with our hypotheses, the results indicate that the presence of health warnings attenuates the influence of mood states on VS, so that happy and sad students tend to converge to similar levels of VS. However, in the absence of health warnings, sad students tend to incorporate significantly more VS than happy students. Similarly, the presence of nutritional labeling attenuates the influence of mood states on VS, so that happy and sad students tend to converge to similar levels of VS. However, in the absence of nutritional labeling, sad students tend to incorporate significantly more VS than happy students. The results provide evidence that making health warnings and nutritional labeling more salient might be a good way to decrease students’ VS tendency for high‐fat snacks.     

视觉正常的自闭症儿童双眼注视点间距的特点及其意义

视网膜上物象对应的外在注视点之间的距离, 即双眼注视点间距(distance of binoculars point of regard, DBPR)在自闭症谱系障碍(autism spectrum disorders, ASD)个体上存在异常的表现, 而ASD个体伴随较高的斜视发病率, 可能会对其双眼注视点间距产生影响。研究采用正弦曲线平滑追踪任务范式, 探索视觉正常的ASD儿童在动态刺激加工过程中DBPR的鉴别意义。结果发现, ASD儿童DBPR过大且具有跨任务类型的稳定性, 且与斜视无关。DBPR在大振幅、快速度的条件下具有优良的鉴别力, 并与自闭症行为量表总分以及感知觉维度显著正相关。结果表明, 双眼注视点间距具有良好的鉴别价值。     

指向性遗忘中认知抑制能力的发展

采用组块提示法,以小学二年级、五年级学生和大学生共104名为被试,考察语词记忆指向性遗忘效应的机制及其发展.结果表明:(1)各年龄段被试都明显存在着指向性遗忘效应;(2)指向性遗忘效应是提取抑制和选择性编码两种机制共同作用的结果,且年幼儿童与年长儿童、成人之间作用情况可能存在差异;(3)小学二年级、五年级学生和大学生之间认知抑制能力差异显著,随年龄增长,认知抑制能力不断增长.     

经颅电刺激与视功能调控

经颅电刺激(Transcranial Electrical Stimulation, TES)通过电极将特定模式的低强度电流作用于大脑头皮以调控皮层活动, 是一种非侵入、无创的神经刺激方法。根据刺激电流的模式的不同, TES分为经颅直流电刺激(tDCS), 经颅交流电刺激(tACS)和经颅随机电刺激(tRNS)。TES能对视功能诸如光幻视阈值、视野、对比敏感度、视知觉运动等进行一定程度上的调控, 并且能够与传统的视觉知觉学习训练相结合以调控视觉功能。对于不同的视觉功能, 不同的TES参数和模式的调控效果有所不同。     

嵌入于社会情境的工作重塑

工作重塑实质上是一种情境性的主动性行为。基于已有研究成果,首先系统归纳工作重塑与社会情境因素之间关系的4种研究视角,即社会情境是工作重塑的目标、社会情境因素是工作重塑的组成部分、社会情境因素影响工作重塑、社会情境因素为工作重塑设立边界条件。此外,梳理并讨论社会情境因素影响工作重塑的内在机制以及社会情境因素与个体特征的交互对于工作重塑的影响、工作重塑在特定情境中的有效性两方面的研究。在此基础上,结合其他相关变量的研究现状对嵌入于社会情境的工作重塑的未来研究进行展望,包括探索工作重塑对他人的影响、探索团队工作重塑驱动个体工作重塑的多重路径、探索社会情境影响工作重塑的内在机制、探索社会情境与个体特征的交互如何影响工作重塑,以及探讨基于中国社会情境的工作重塑的有效性。     

Enduring cognitive dysfunction in unipolar major depression: A test–retest study using the Stroop paradigm

Hammar, Å., Sørensen, L., Årdal, G., Oedegaard, K.J., Kroken, R., Roness, A. & Lund, A. (2009). Enduring cognitive dysfunction in unipolar major depression: A test–retest study using the Stroop‐paradigm. Scandinavian Journal of Psychology. The aim of the study was to investigate automatic and effortful information processing with the Stroop paradigm in a long term perspective in patients with major depressive disorder (MDD). Patients were tested at two test occasions: at inclusion with a Hamilton Depression Rating Scale (HDRS) score >18, and after 6 months, when most patients had experienced symptom reduction. The Stroop paradigm is considered to measure aspects of attention and executive functioning and consists of three conditions/cards: naming the color of the patches (Color), reading of the color‐words (Word) and naming the ink color of color‐words (Color‐Word). The Color‐Word condition is proved to be the most cognitive demanding task and requires the proband to actively suppress interference and is therefore considered to require more effortful information processing, whereas naming the color of the patches and reading the color‐words are expected to be more automatic and less cognitive demanding. A homogenous group of 19 patients with unipolar recurrent MDD according to DSM‐IV and a HDRS score of >18 were included in the study. A control group was individually matched for age, gender and level of education. Depressed patients performed equal to the control group on the Color and Word cards at both test occasions. However, the patients were impaired compared with the control group on the Color‐Word card task at both test occasions. Thus, the depressed patients showed no improvement of effortful attention/executive performance as a function of symptom reduction. The results indicate that the depressed patients showed impaired cognitive performance on cognitive demanding tasks when symptomatic and that this impairment prevailed after 6 months, despite significant improvement in their depressive symptoms.     

Modeling the Gratification-Seeking Process of Television Viewing

This study attempted to establish the audience activity construct as an intervening factor in the gratification-seeking process, by taking into account the expanded viewing options in the emerging multichannel environment. It examined the viewing motives, activities, and satisfaction of adolescents—the first generation to grow up in that environment. The major theoretical assumption tested was whether more strongly motivated viewers would more actively engage in various audience activities throughout the viewing process and receive greater viewing satisfaction afterwards. Findings from testing the path model generally support this assumption. However, the role of media exposure in the gratification-seeking process comes into question due to its lack of causal linkage to several model components. A revised theoretical model is proposed to help inform future research.
