改革开放以来我国媒介伦理的研究及其反思

改革开放以来,随着传播学研究的深入开展,媒介伦理学的研究也取得了相当的成就。学者们重点研究了传媒伦理的基本理论、实践中的问题与冲突、以及提高传媒伦理建设水平的措施等问题,也有少数学者就媒介伦理的功能、媒介伦理与和谐社会建构、媒介伦理的研究历史作了尝试性的探讨。但也应该看到较之医学伦理等其他分支伦理学的研究,媒介伦理学的研究依然处于起步阶段,还存在诸多的研究空白。     

和谐医患命运共同体建设的思考

医患关系作为医疗诊治活动中最主要的关系,是以医护人员为核心的群体与以患者为核心的群体之间的关系。近来,医患关系在一定程度上的对立以及由此引发的社会公共事件激起了广泛的社会反响。旨在通过构建人类命运共同体对医患关系的启示,结合社会现实和医患关系实际,从医患双方生命至重的理念统一、防病治病的过程统一、平等尊重的人文情怀统一以及权利义务的关系统一等方面,对当前医患关系进行深入分析,对“和谐医患命运共同体”的建设加以阐释,以期对医患关系的深入探讨提出可行性的建议和支持。     

An associative account of the development of word learning

Word learning is a notoriously difficult induction problem because meaning is underdetermined by positive examples. How do children solve this problem? Some have argued that word learning is achieved by means of inference: young word learners rely on a number of assumptions that reduce the overall hypothesis space by favoring some meanings over others. However, these approaches have difficulty explaining how words are learned from conversations or text, without pointing or explicit instruction. In this research, we propose an associative mechanism that can account for such learning. In a series of experiments, 4-year-olds and adults were presented with sets of words that included a single nonsense word (e.g. dax). Some lists were taxonomic (i.,e., all items were members of a given category), some were associative (i.e., all items were associates of a given category, but not members), and some were mixed. Participants were asked to indicate whether the nonsense word was an animal or an artifact. Adults exhibited evidence of learning when lists consisted of either associatively or taxonomically related items. In contrast, children exhibited evidence of word learning only when lists consisted of associatively related items. These results present challenges to several extant models of word learning, and a new model based on the distinction between syntagmatic and paradigmatic associations is proposed.     

The relationship between fluid intelligence and sustained inattentional blindness in 7-to-14-year-old children

Previous researches have shown that people with higher fluid intelligence are more likely to detect the unexpected stimuli. The current study systematically explored the relationship between fluid intelligence and sustained inattentional blindness in children. In Experiment 1, we measured one hundred and seventy-nine 7-to-14-year-old children’s fluid intelligence and sustained inattentional blindness. The results showed that fluid intelligence was negatively related to sustained inattentional blindness only in 7-to-8-year-old children. In Experiment 2, we explored sustained inattentional blindness in sixty children with high Raven’s scores. We found that compared with children who have average Raven’s scores aged 11-to-12 years old, children with high Raven’s scores were unable to better avoid sustained inattentional blindness. In general, this research implies that the relation between fluid intelligence and sustained inattentional blindness is weak. Fluid intelligence could predict sustained inattentional blindness only when children do not have enough perceptual capacities to complete the primary task.     

Spatial navigation: Cognitive variables involved in route retracing among an elderly population

The cognitive processes involved in route retracing are not well known. This study aims to highlight them in an elderly population in which contradictory results have been obtained, certain studies showing specific difficulties for route retracing, others not. Thirty-nine elderly subjects performed a route-learning task (forward-backward) in a garden, then completed spatial knowledge tasks and standardised cognitive tests. Results show four factors that were predictive of route retracing performance: route repetition, the pointing task, and two standardised cognitive tests, one assessing spatial working memory, and another global cognitive efficiency. According to these results, route retracing involves route and survey knowledge (i.e., egocentric and allocentric strategy), and the integration of forward-backward perspectives is underpinned by the spatial working memory. Moreover, the subjects did not make more errors in route retracing than in the route repetition task, suggesting that a real environment could compensate for a failing allocentric strategy.     

Using Experiential Learning Theory to Train Career Practitioners

Effective instructional strategies are needed for career practitioner training. Experiential learning theory (ELT; A. Y. Kolb & Kolb, 2009) provides an instructional foundation from which awareness of the various components of career development can be enhanced. Support for ELT as an effective method of instruction exists in various fields (Hoover, Giambatista, Sorenson, & Bommer, 2010; Ti et al., 2009). ELT integrates 6 shared propositions derived from John Dewey, Jean Piaget, William James, Carl Jung, and Carl Rogers (A. Y. Kolb & Kolb, 2009). This article outlines components of ELT and their application in training career service practitioners.     

Direct assessment of the cognitive correlates of attention deficit disorders with and without hyperactivity

The cognitive functioning of children identified as attention deficit disorder with hyperactivity (ADD/H) was compared to that of children identified as attention deficit disorder without hyperactivity (ADD/WO). Based on information on symptoms supplied by teachers, 20 ADD/H and 15 ADD/ WO children were selected according to DSM-III criteria from a large elementaryschool learning disabilities and behavior disorders population. For comparison purposes, 16 normal children from regular classrooms were also selected. Children from all three groups were evaluated with a battery of cognitive tests. Intelligence test scores differentiated the two ADD groups, with the ADD/H children obtaining significantly lower Full Scale IQ scores than both ADD/WO and control children. In addition, ADD/H children obtained significantly lower Verbal IQ scores than ADD/WO children. Both ADD groups performed more poorly than controls on Spelling and Reading Achievement, and the ADD/WO group performed more poorly on Math Achievement. The two ADD groups took longer to complete six Stroop and rapid naming tasks than the control groups but did not differ among themselves. The ADD/WO group made more errors on a visual matching task than the controls, but neither ADD group differed from controls on the accuracy of the Stroop tasks, rapid naming tasks, measures of receptive and expressive language, visual-motor integration, or sustained visual attention. The differences between the two ADD groups were fewer than expected on the basis of previous research and are more global than specific.The assistance of John Junginger, Jason Walker, and Cynthia Jones at various stages of the project is gratefully acknowledged.
