索引词不同于专名和限定描述语,因此需要一个专门的语义理论对其进行解释。本文首先介绍了索引词的经典解释理论——Kaplan([15])的二维语义论,然后考察了反驳Kaplan理论的四类反例:(a)"only"辖域中受宽松约束的"Ⅰ";(b)第一人称涉己信念报告;(c)转换索引词;(d)延指现象。综合这四类反例的最新研究成果,我们得出的结论是:这些反例不足以否定Kaplan关于索引词直接指称的论断,但Kaplan所否认的"怪兽"确实是存在的。基于此,我们指出需要进一步研究的问题,并在文末从索引词研究的角度探讨了汉语中的"我"和"自己"。  相似文献

Previous work has demonstrated that cued recall of a term from a fact yields learning that does not transfer, relative to a restudy control, to recall of another term from the same fact. Here we report six experiments in which a series of manipulations during the initial study and training phases of learning, hypothesized to increase transfer for process‐based biology concepts, were investigated. In Experiments 1 and 2, fill‐in‐the‐blank questions combined with immediate or delayed and repeated correct answer feedback improved learning but not transfer. In Experiments 3 and 4, practice questions that involved recalling process steps, understanding ordinal relationships, or making inferences did not improve transfer. Positive transfer was produced, however, in Experiments 5 and 6 via retrieval–verification–scoring, a new method in which difficult fill‐in‐the‐blank questions were combined with extensive feedback processing. We discuss implications for transfer in both theoretical and applied contexts.  相似文献

以依恋理论为基础的研究已证明依恋对情绪调节的影响,但这些研究忽视了情绪调节作为一个过程的复杂性和多样性,因此现有研究无法回答依恋为何会对情绪调节产生影响。扩展过程模型将情绪调节分为三个阶段,并清晰地描述了情绪调节的过程以及过程中各因素之间的关系。从该模型来看,在情绪调节的三个阶段均可发现与依恋有关的个体差异,并且依恋对于情绪调节早期阶段的影响可能是导致后期阶段产生个体差异的原因。未来的研究应在探讨依恋对情绪调节的影响的同时关注环境因素的影响;设计新的实验范式以证实情绪调节三阶段的连续性并探索依恋影响情绪调节的潜在机制;探讨依恋对情绪调节灵活性的影响。此外,未来的干预研究应设计更具针对性的干预措施来改善非安全依恋个体的情绪调节。  相似文献

ABSTRACT

A within-person diary research design with 39 full-time workers was used to examine the effects of daily cross-domain usage of information and communication technologies (ICTs) on job-related performance and stress in both workplace and home domains. Segmentation preference effects on links between cross-domain ICT usage and both job performance and job stress were also analyzed. A positive association was found for the first relationship in mixed home-workplace contexts, and a negative association for the second in home contexts only. A stronger segmentation preference effect on the negative relationship between cross-domain ICT usage and job stress was found for integrators (employees who integrate work and home domains) compared to separators (employees who separate work/non-work activities). Our findings suggest that daily cross-domain ICT usage can enhance job performance and reduce job stress, with a moderating effect of segmentation preference on the link between cross-domain ICT usage and job stress.  相似文献

池莉倡导“原生态写作”,主要表现在文本的实录感上。池莉从不将人物变成政治道德价值的符号,她的作品中毫无概念化的痕迹,她反对按理论教条营造情节,将生活理性化,也不愿片面地去搜寻自然界、社会中的温馨的美好,将生活“诗意化”,而是要“写和我们生活一样真实的小说”。因此,她以实证的方式考察生活,以实录的方式再现生活,给人以真人真事的实录感。在其写作中,非常集中而深刻地表现了女性的情怀,表现在有意模糊性别、突出欲望主体、逃离爱情的意义几方面。  相似文献

ABSTRACT

Sequential modulations in symbolic cueing tasks have been attributed to complete versus partial repetition/alternation of stimulus features between consecutive trials. This feature-integration hypothesis is questioned by recent findings and further investigated in the present study. In the first two experiments, when the cueing axes switched between trials, only complete alternation of cue directions and target locations existed. Nevertheless, significant sequence effects were still found in this condition, which did not support the feature-integration hypothesis. Furthermore, although sequence effects were still significant when stimulus identities were manipulated in Experiment 3, it was abolished when different cue categories (gaze and arrow) were presented as cues in Experiment 4. The findings suggest that the integration of stimulus features is not the only source of the sequential effect and some higher level cognitive mechanisms, possibly as described in the task-file or task organization hypotheses, are involved in the sequential modulations of symbolic cueing.  相似文献

Drug poisoning is the leading method of suicide‐related deaths among females and third among males in the United States. Alcohol can increase the severity of drug poisonings, yet the prevalence of alcohol overdoses in suicide‐related drug poisonings (SRDP) remains unclear. Data from the Nationwide Inpatient Sample was examined to determine rates of inpatient hospital stays for SRDP and co‐occurring alcohol overdoses in adolescents (ages 12–17) and young adults (ages 18–24) between 1999 and 2008. Among adolescents, there were 14,615 hospitalizations for drug poisonings in 2008, of which 72% (10,462) were suicide‐related at a cost of $43 million. Rates of SRDP in this age group decreased between 1999 and 2008. The prevalence of co‐occurring alcohol overdoses increased from 5% in 1999 to 7% in 2008. Among young adults, there were 32,471 hospitalizations for drug poisonings in 2008, of which 64% (20,746) were suicide‐related at a cost of $110 million. Rates of SRDP did not change significantly between 1999 and 2008. The prevalence of co‐occurring alcohol overdoses increased from 14% in 1999 to 20% in 2008. Thus, while rates of SRDP decreased for adolescents and remained unchanged for young adults, the prevalence of co‐occurring alcohol overdoses increased for both age groups. Such hospitalizations provide important opportunities to employ intervention techniques to prevent further suicide attempts.  相似文献

In this reply to the commentaries by Xinyin Chen, Charissa Cheah, Yiyuan Xu, and Dawn Watling, we further discuss the conceptual and methodological challenges that arise when attempting to study beliefs about social withdrawal (1) in the unique cultural context of China and (2) in the unique developmental age period of early childhood.  相似文献
